The Long Straddle

View chapters →

10.1 – The directional dilemma

How many times have you been in a situation wherein you take a trade after much conviction, either long or short and right after you initiate the trade the market moves just the other way round? All your strategy, planning, efforts, and capital go for a toss. I’m certain this is one situation all of us have been in. In fact this is one of the reasons why most professional traders go beyond the regular directional bets and set up strategies which are insulated against the unpredictable market direction.

Strategies whose profitability does not really depend on the market direction are called “Market Neutral” or “Delta Neutral” strategies. Over the next few chapters we will understand some of the market neutral strategies and how a regular retail trader can execute such strategies. Let us begin with a ‘Long Straddle’. M6-C10-Cartoon

10.2 – Long Straddle

Long straddle is perhaps the simplest market neutral strategy to implement. Once implemented, the P&L is not affected by the direction in which the market moves. The market can move in any direction, but it has to move. As long as the market moves (irrespective of its direction), a positive P&L is generated. To implement a long straddle all one has to do is –

  1. Buy a Call option
  2. Buy a Put option

Ensure –

  1. Both the options belong to the same underlying
  2. Both the options belong to the same expiry
  3. Belong to the same strike

Here is an example which explains the execution of a long straddle and the eventual strategy payoff. As I write this, the market is trading at 7579, which would make the strike 7600 ‘At the money’. Long straddle would require us to simultaneously purchase the ATM call and put options. Image 1_Setup As you can see from the snapshot above, 7600CE is trading at 77 and 7600 PE is trading at 88. The simultaneous purchase of both these options would result in a net debit of Rs.165. The idea here is – the trader is long on both the call and put options belonging to the ATM strike. Hence the trader is not really worried about which direction the market would move.

If the market goes up, the trader would expect to see gains in Call options far higher than the loss made (read premium paid) on the put option. Similarly, if the market goes down, the gains in the Put option far exceeds the loss on the call option. Hence irrespective of the direction, the gain in one option is good enough to offset the loss in the other and still yield a positive P&L.  Hence the market direction here is meaningless. Let us break this down further and evaluate different expiry scenarios.

Scenario 1 – Market expires at 7200, put option makes money This is a scenario where the gain in the put option not only offsets the loss made in the call option but also yields a positive P&L over and above. At 7200 –

  • 7600 CE will expire worthless, hence we lose the premium paid i.e Rs. 77
  • 7600 PE will have an intrinsic value of 400. After adjusting for the premium paid i.e Rs.88, we get to retain 400 – 88 = 312
  • The net payoff would be 312 – 77 = + 235

As you can see, the gain in put option after adjusting for the premium paid for put option and after adjusting for the premium paid for the call option still yields a positive P&L.

Scenario 2 – Market expires at 7435 (lower breakeven) This is a situation where the strategy neither makes money nor loses any money.

  • 7600 CE would expire worthless; hence the premium paid has to be written off. Loss would be Rs.77
  • 7600 PE would have an intrinsic value of 165, hence this is the gain in the put option
  • However the net premium paid for the call and put option is Rs.165, which gets adjusted with the gain in the put option

If you think about it, with respect to the ATM strike, market has indeed expired at a lesser value. So therefore the put option makes money. However, the gains made in the put option adjusts itself against the premium paid for both the call and put option, eventually leaving no money on the table.

Scenario 3 – Market expires at 7600 (at the ATM strike) At 7600, the situation is quite straight forward as both the call and put option would expire worthless and hence the premium paid would be gone. The loss here would be equivalent to the net premium paid i.e Rs.165.

Scenario 4 – Market expires at 7765 (upper breakeven) This is similar to the 2nd scenario we discussed. This is a point at which the strategy breaks even at a point higher than the ATM strike.

  • 7600 CE would have an intrinsic value of 165, hence this is the gain in Call option
  • 7600 PE would expire worthless, hence the premium paid towards the option is lost
  • The gain made in the 7600 CE is offset against the combined premium paid

Hence the strategy would breakeven at this point.

Scenario 5 – Market expires at 8000, call option makes money Clearly the market in this scenario is way above the 7600 ATM mark. The call option premiums would swell, so much so that the gains in call option will more than offset the premiums paid. Let us check the numbers –

  • 7600 PE will expire worthless, hence the premium paid i.e Rs.88 is to be written off
  • At 8000, the 7600 CE will have an intrinsic value of 400
  • The net payoff here is 400 – 88 – 77 = +235

So as you can see, the gain in call option is significant enough to offset the combined premiums paid. Here is the payoff table at different market expiry levels. Image 2_payofftable As you can observe –

  1. The maximum loss (165) occurs at 7600, which is the ATM strike
  2. The profits are unlimited in either direction of the market

We can visualize these points in the payoff structure here – Image 3_Payoff From the V shaped payoff graph, the following things are quite clear –

  1. With reference to the ATM strike, the strategy makes money in either direction
  2. Maximum loss is experienced when markets don’t move and stay at ATM
    1. Max loss = Net premium paid
  3. There are two breakevens – on either side, equidistant from ATM
    1. Upper Breakeven = ATM + Net premium
    2. Lower Breakeven = ATM – Net premium

I’m certain, you find this strategy quite straight forward to understand and implement. In summary, you buy calls and puts, each leg has a limited down side, hence the combined position also has a limited downside and an unlimited profit potential. So in essence, a long straddle is like placing a bet on the price action each-way  – you make money if the market goes up or down. Hence the direction does not matter here. But let me ask you this – if the direction does not matter, what else matters for this strategy?

10.3 – Volatility Matters

Yes, volatility matters quite a bit when you implement the straddle. I would not be exaggerating if I said that volatility makes or breaks the straddle. Hence a fair assessment on volatility serves as the backbone for the straddle’s success. Have a look at this graph below – Image 4_volatility The y-axis represents the cost of the strategy, which is simply the combined premium of both the options and the x-axis represents volatility. The blue, green, and red line represents how the premium increases when the volatility increases given that there is 30, 15, and 5 days to expiry respectively. As you can see, this is a linear graph and irrespective of time to expiry, the strategy cost increases as and when the volatility increases. Likewise the strategy costs decreases when the volatility decreases.

Have a look at the blue line; it suggests when volatility is 15%, the cost of setting up a long straddle is 160. Remember the cost of a long straddle represents the combined premium required to buy both call and put options. So at 15% volatility it costs Rs.160 to set up the long straddle, however keeping all else equal, when volatility increases to 30% it costs Rs.340 to set up the same long straddle. In other words, you are likely to double your money in the straddle provided –

  1. You set up the long straddle at the start of the month
  2. The volatility at the time of setting up the long straddle is relatively low
  3. After you set up the long straddle, the volatility doubles

You can make similar observations with the green and red line which represents the ‘price to volatility’ behavior when the time to expiry is 15 and 5 days respectively. Now, this also means you will lose money if you execute the straddle when the volatility is high which starts to decline after you execute the long straddle. This is an extremely crucial point to remember. At this point, let us have a quick discussion on the overall strategy’s delta. Since we are long on ATM strike, the delta of both the options is close to 0.5.

  • The call option has a delta of + 0.5
  • The put option has a delta of – 0.5

The delta of call option offsets the delta of put option thereby resulting in a net ‘0’ overall delta. Recall, delta shows the direction bias of the position. A +ve delta indicates a bullish bias and a -ve delta indicates a bearish bias. Given this, a 0 delta indicates that there is no bias whatsoever to the direction of the market. So all strategies which have zero deltas are called ‘Delta Neutral’ and Delta Neutral strategies are insulated against the market direction.

10.4 – What can go wrong with the straddle?

On the face of it a long straddle looks great. Think about it – you get to make money whichever way the market decides to move. All you need is the right volatility estimate. Therefore, what can really go wrong with a straddle? Well, two things come in between you and the profitability of a long straddle –

  1. Theta Decay – All else equal, options are depreciating assets and this particularly hurts long positions. The closer you get to expiration, the lesser time value of the option. Time decay accelerates exponentially during the last week before expiration, so you do not want to hold onto out-of-the-money or at-the-money options into the last week and lose premiums rapidly.
  2. Large breakevens – Recollect, in the example we discussed earlier, the breakeven points were 165 points away from the ATM strike. The lower breakeven point was 7435 and the upper breakeven was 7765, considering the ATM strike was 7600. In percentage terms, the market has to move 2.2% (either ways) to achieve breakeven.This means that from the time you initiate the straddle, the market or the stock has to move atleast 2.2% either ways for you to start making money…and this move has to happen within a maximum of 30 days. Further if you want to make a profit of atleast 1% on this trade, then we are talking about a 1% move over and above 2.2% on the index. Such large move on the index is quite a challenge in my opinion and I will explain why in the next chapter.

Keeping the above two points plus the impact on volatility in perspective, we can summarize what really needs to work in your favor for the straddle to be profitable –

  1. The volatility should be relatively low at the time of strategy execution
  2. The volatility should increase during the holding period of the strategy
  3. The market should make a large move – the direction of the move does not matter
  4. The expected large move is time bound, should happen quickly – well within the expiry

From my experience trading long straddles, they are profitable when setup around major market events and the impact of such events should exceed over and above what the market expects. Let me explain the ‘event and expectation’ part a bit more, please do read the following carefully. Let us take the Infosys results as an example here.

Event – Quarterly results of Infosys

Expectation – ‘Muted to flat’ revenue guideline for the coming few quarters.

Actual Outcome – As expected Infosys announces ‘muted to flat’ revenue guideline for the coming few quarters. If you were the set up a long straddle in the backdrop of such an event (and its expectation), and eventually the expectation is matched, then chances are that the straddle would fall apart. This is because around major events, volatility tends to increase which tends to drive the premium high.

So if you are to buy ATM call and put options just around the corner of an event, then you are essentially buying options when the volatility is high. When events are announced and the outcome is known, the volatility drops like a ball, and therefore the premiums. This naturally breaks the straddle down and the trader would lose money owing to the ‘bought at high volatility and sold at low volatility’ phenomena. I’ve noticed this happening over and over again, and unfortunately have seen many traders lose money exactly for this reason.

Favorable Outcome – However imagine, instead of ‘muted to flat’ guideline they announce an ‘aggressive’ guideline. This would essentially take the market by surprise and drive premiums much higher, resulting in a profitable straddle trade. This means there is another angle to straddles – your assessment of the event’s outcome should be couple of notches better than the general market’s assessment.

You cannot setup a straddle with a mediocre assessment of events and its outcome. This may seem like a difficult proposition but you will have to trust me here – few quality years of trading experience will actually get you to assess situations way better than the rest of the market. So, just for clarity, I’d like to repost all the angles which need to be aligned for the straddle to be profitable –

  1. The volatility should be relatively low at the time of strategy execution
  2. The volatility should increase during the holding period of the strategy
  3. The market should make a large move – the direction of the move does not matter
  4. The expected large move is time bound, should happen quickly – well within the expiry
  5. Long straddles are to be set around major events, and the outcome of these events to be drastically different from the general market expectation.

You may be wondering there are far too many points that come in between you and the long straddle’s profitability. But worry not, I’ll share an antidote in the next chapter  – The Short Straddle, and why it makes sense.

Key takeaways from this chapter

  1. Strategies which are insulated to market direction are called ‘Market Neutral’ or ‘Delta neutral’
  2. Market neutral strategies such as long straddle makes money either which way the market moves
  3. Long straddle requires you to simultaneously buy the ATM Call and Put option. The options should belong to the same underlying, same strike, and same expiry
  4. By buying the CE and PE – the trader is placing the bet on either direction
  5. The maximum loss is equal to the net premium paid, and it occurs at the strike at which the long straddle has been initiated
  6. The upper breakeven is ‘strike + net premium’. The lower breakeven is ‘strike – net premium’
  7. The deltas in a long straddle adds up to zero
  8. The volatility should be relatively low at the time of strategy execution
  9. The volatility should increase during the holding period of the strategy
  10. The market should make a large move – the direction of the move does not matter
  11. The expected large move is time bound, should happen quickly – well within the expiry
  12. Long straddles are to be set around major events, and the outcome of these events to be drastically different from the general market expectation.

    Thanks for the wonderful chapter.. Where to find the financial events sir.?

  2. Ravinder singh sandhu says:

    Thanks sir ji, you are a super man

  3. sastry says:

    Dear Sir,long and
    Please indicate the probable range of VIX- LOW VOLATALITY AND HIGH VOLATALITY in general out of your very good experience for both INDEX and OPTIONS strategies either for long or short because I am a new beginner for my guidance. Thanks and Best Regards, R V N Sastry

    • Karthik Rangappa says:

      Sastry – I’d consider ViX values around 15% as low and about 25-28% as high. However for stock it can vary…something like 40% for Infy is high and 20% can be low.

  4. suresh.ks says:

    How many days will it take to complete this OPtion Strategy module and how many lessons are left?

  5. Ravi says:

    Sir when u start module – Trading Psychology and Money Management.. Which consists 90% of trading ( 60% for trading Psychology + 30% for money management)…
    U r covering only 10% of trading….
    Please Start Trading Psychology module as soon as possible..
    Its my opinion that without knowing Trading psychology and money management… No one can become successful trader ..
    Ur writing skill is superb.. I have been waiting for Trading Psychology module for 5 months…still I think I have to wait 4-5 months. ?

  6. Yes this works out perfectly when the direction of the market trend is one sided, either well up or well down.

  7. Jatin says:

    Sir, I am eagerly waiting for PDF modules. When can we get it?? As they are more suitable for printing and reading

  8. Sushreet Pattanayak says:

    Isn’t a long put straddle better than a long straddle in all scenarios? Wherein we’d be taking a long position and a put option with a strike price of the entry price for the same underlying script. You’d be saving on the call option premium so your margins would be better. Rest would work the same way. Would there be a scenario when a long straddle is better than a long put straddle?

    • Karthik Rangappa says:

      Not sure if there is anything like a ‘long put straddle’. The strategy that you are talking about – isit like buying Futures plus buying put? If yes, this would be an expensive strategy as it requires margin deposits for the futures.

      • R P HANS says:

        Sir, Long future and long put will it not be equal to long call synthetic? Its pay out will be entirely different from the long straddle.
        pl. correct if i have misunderstood the question of Shri Sushreet Pattanayak

        Just a minor thing. This module has started and its 10 chapters are over so it is better to remove the word “Coming Soon” from the module graphics.

        • Sushreet Pattanayak says:

          Hi R. Wouldn’t the payouts be similar? Your profit would be future price-strike price-premium if the script appreciates or strike price-future price-premium if the script depreciates. Am I right Karthick? If so notwithstanding margin money isn’t this a more efficient trade with respect to payouts (no CE premium)? Sorry if my understanding is off point, very new to F&O.

          • Karthik Rangappa says:

            Sushreet – I guess the best way to understand the payoff would be to actually plot it and visualize it on excel. Whenever we have more than 2 option legs, the payoff are tricky and you need to visualize it to understand how they work.

        • Karthik Rangappa says:

          Long Call and short put would make a synthetic call and its payout will be similar to that of a long futures, and yes, it is completely different from a long straddle.

          Thanks for point the graphics bit :)… we are just few more chapters away from closing this module, guess we will replaced it the module graphics at a later stage.

  9. Sushreet Pattanayak says:

    Oh also a big shout-out to you guys for Zerodha Varsity. Very lucid writing!

  10. Nivedita Natekar says:

    Request you to kindly send somebody to explain the whole procedure of buying and selling on the website

  11. Preetam says:

    An observation which I would like to share.
    Call Delta: 50
    Put Delta: 50
    Nifty increase from 7760 to 7791.
    VIX decreases from 17.84 to 17.42

    But increase in call option is only 9 points, whereas put option decreased by 20 points. Why is the increase in call option less than put option?


    • Karthik Rangappa says:

      Couple of reasons –

      1) When Volatility drops, premiums drop. In this case volatility dropped and market increased , both are favorable for the drop in Put premiums
      2) Call option has gone up because the markets increased, but then volatility has dropped which limits the increase in premiums.

  12. shravan says:

    how to calculate delta value and how to know that volatility is 15 % sir?


    Hi Karthik,

    When will i expect the commodity module. I’m wait for that.

  14. Beena Chauhan says:

    Sir please suggest me some website name which gives me the knowledge about base metals

  15. Khyati Verdhan says:

    Hi kartik
    Please teach me some rules/ways of BTST/STBT trade

    • Karthik Rangappa says:

      The only two things to keep in mind while doing BTST – look for high volume breakouts and trade only liquid stocks!

  16. Deepak gagrani says:

    Sir can you share u comment when we can take positions on CE and PE at same time. Means just after the expiry or wait 4-5 days after the expiry and how to calculate premium.

    • Karthik Rangappa says:

      To calculate the premium you can use the B&S calculator here –

      You can initiate the straddle anytime you wish – just make sure the volatility is low and you expect it to increase over your holding period.

      • Deepak gagrani says:

        But how much minimum volatility %. Link which u have shared.
        Not working

        • Karthik Rangappa says:

          The least volatility I’ve seen in Nifty is around 13%, hopefully this should give you a perspective.

          • Deepak gagrani says:

            Sir on 13-04 icici bank trading on 244 on days high and same time 240 PE was trading on implied volatility 27.75 and CE at 27.31. So can we buy or sell put or call. And the same time 220 PE was trading in implied volatility in both the scenario can we buy put and hope market will come down

          • Karthik Rangappa says:

            Well, this depends on many factors including Volatility. You will have to check how the volatility of 27.75 fares with respect to ICICI’s historical volatility. If its low and expected to increase, then yes volatility is a favorable factor for establishing a Long position.

  17. Sooraj Jogendra Mishra says:

    Karthik Sir,
    As you said long straddle is useful when event are coming like announcement of quarterly results….We come to know results dates on site like moneycontol etc but do you know any site that also tells about timing of such announcements…?? because some companies results are announced after market hours while some announced during market hours… that make me confused whiling making positions…

  18. Shanky Agrawal day. says:

    Hello Sir

    How can we exercise the option purchased. On the last expiration day can we exercise on any price prevailing on that day.

    • Karthik Rangappa says:

      Yes, you can exercise the option only on the day of the expiry at prevailing market rates.

      • SUBHANKAR SAHA says:


  19. Rajesh says:

    This year, I have some profit from Intra Day trading and for which I have to fill up ITR 4 for speculative income. Pls tell me what details should I provide to CA to enable him to fill up the speculative income part of the ITR 4. I plan to take the help of AERI.

  20. rohan says:

    By volatility you mean IV?
    nifty spot is at 7884, 7900CE IV is 15.7 and 7900PE IV is 15.13, is it advisable to place long straddle before 19 may election results?

    • Karthik Rangappa says:

      Yes, provided you also expect the volatility to go up in the timeframe you expect to hold the trade.

  21. Naresh says:

    Hi Karthik, Is there a workable and accessible software in which one can create a marketwatch of spreads, strangles etc and track the daily variations and its chart of premiums paid/received ? Both for current series and historic records etc. Something like show me the strangle price from 1st June to 17th June for 8100 June series. Maybe past records as well for comparison. Does options oracle do the same job ? IS it a working software ? Is it a licensed product ? Thanks

  22. CHAIT says:

    Can we check IV in real time in the charts?
    “Historical Volatility” in the studies column of KITE is not at all close to IV in the options chart of NSE. how is HV related to IV in NSE chart?
    please give clarity.

    • Karthik Rangappa says:

      As far as I know there are no charts where you can track the live IVs. Probably the India Vix is your best option. HV is the realized volatility in the past, and IV is what the market is expecting as on now.

  23. Vishal Javakhedkar says:

    I think this strategy is better suited for bank nifty weekly option, where you will start making profit once it move 1.5 % in either direction or stocks like Bhel which generally is very volatile, and yes as you said key is to buy when volatility at the lowest.

  24. Chandan says:

    Since the premium for ATM might be higher can we take this strategy on slight OTM strike?

  25. Rajesh Gupta says:

    Thanks for such a beautiful article on option. In your this chapter point no 11.4, there is a question from your side. After initiating straddle, as the market move, will your position still remain delta neutral???. I am not sure about the answer of this question. However i think, After initiating straddle, as the market moves, the strategy will NOT BE DELTA NEUTRAL. But i don’t know how to keep it Delta neutral. Please gives us more insight on this.

    Rajesh Gupta

    • Karthik Rangappa says:

      You are right Rajesh. After you initiate the position, and when the market moves…the position will not be delta neutral. I will try and put up an additional chapter (but not anytime soon) related to this topic.

  26. amit gupta says:

    for long straddles,it is necessary to buy at ATM only ,or choose to buy whether the least volatility at both CE&PE .because it is quite rare to get the low volatility at ATM ,so suggest ,whether choose to buyat strike where volatility would low compare to other strikes ,whether it is otm/itm ,not necessary at ATM.Kindly suggest.

    • Karthik Rangappa says:

      If you choose low volatility strikes, then chances are you will pick two different strikes (as its hard to find the same strike at which vols are low)…and therefore it will not be a straddle.

  27. Dwaipayan says:

    I have one confusion, when you are calculating the final price of the option , you are showing the difference between the purchase price and the intrinsic value. This holds good in case of a contract , but if we compare the spot price of the contracts at the day of expiry both the call and put option values reach close to zero. Thus , when the market squares off my position will it pay me the difference on basis of intrinsic value of the option or the spot price ?

    • Karthik Rangappa says:

      I’m a little confused with your question. Can you please quote with an example? The intrinsic value will be zero, if the option is OTM.

      • Dwaipayan Chakraborty says:

        Ok let me rephrase and make it simpler, the LTP for NIFTY CE 8400 for Sep 29,2016 Expiry as on close of Sep 29,2016 was 188.3, as the price of underlying asset i.e NIFTY was 8591, the intrinsic value of the contract should be 191, so after the exchange squares off the option on expiry what is credited to my account, 188.3 or 191 ?

  28. amit gupta says:

    I have read all your chapters and find long straddles and long strangle both are similar ,only difference moneyness selection .please clear the doubt while execution of buy CE&PE in long strangle must be same time or i can execute at different time interval .and generally delta would never be zero in long strangle ,and it is also possible the liquidity and OI would not be available in one of the OTM moneyness during execution ,then what would have to do ,Should wait for time passes ,kindly elaborate with certain example ..

    • Karthik Rangappa says:

      The idea behind both the strategies is to execute them at same point. Executing at different intervals may not really give the desired outcome of the strategy.

  29. Vishal Javakhedkar says:

    Hi Karthik,
    I am able to apply this strategy on weekly banknifty and success rate has been closed to 70% but issue is with stoploss, in case bank nifty doesn’t move I am not able to take a decision when to put stoploss and because of it I am still in loss position. any input on the scenario?

    • Karthik Rangappa says:

      Try hedging it with month end contract 🙂

      • Vishal Javakhedkar says:

        I didn’t get you. Do you mean to say I should apply long straddle on Monthly bank nifty options?

        • Karthik Rangappa says:

          Long straddle on weekly and short on monthly…this is just an idea, you may want to test inside out to see if it makes any sense.

          • Vishal says:

            Can I back test using zerodha, i tried it but i don’t think option trading strategics best testing is available

          • Karthik Rangappa says:

            Its hard to back test option strategies…you will need to download the data and probably run some code to back test.

  30. amit gupta says:

    Hi Karthik,

    Can you suggest books or online availability of data for knowing depth knowledge of technical analytics ,and also suggest some free trading platform so i can execute my trade ,I have done enough paper trading,in which 90% were perfect ,but when i actually started on pi ,result was different due to my sentiments .I have done day trading most of the time .so suggest accordingly .

  31. Bhaskar says:

    Hi please let me know following trade can I execute or not?

    SBI market price 250
    CAll buy OTM 235 = 1.85 rs
    Put buy OTM 275 = 1.85rs
    if sbi price moves to 270 then following is the scenario
    CAll value 235 = 0.85 rs
    Put value 275 = 3.85rs
    I can square off it and take profit or sbi should reach strike price??

    • Karthik Rangappa says:

      If SBI is 250, 235CE is ITM and its minimum value should be Rs.15….like wise fro 275PE.

      • Bhaskar says:

        sorry for confusion..
        just learning thru eg before actual option trading
        Sbi today price 270.00

        If I buy call 11.75 & put 6.75

        and next day sbi moves to 290

        then can I square off money making call option?

  32. Sachin Jain says:

    Is it a good time to entering in Long Straddle Strategy as the market is moving very fast in either directions. Should we enter into Dec’16 7900 call and put. The call premium is 229 & put is 133.

    • Karthik Rangappa says:

      If you have the conviction, you should 🙂

      If you do not have the conviction, then you need to ask yourself – why so? Probably, you will be required read up and understand more 🙂

    Is it possible from your end to share the Nifty options data for 16 years? It’s a pain to download manually from nse site.

    • Karthik Rangappa says:

      Options is not more than 10 years old in India 🙂

      Btw, this may not be possible from our end. I’d suggest you speak to a licensed data vendor like ‘True data’ for this. Good luck.

    Hy karthik

    “‘Delta Neutral’ and Delta Neutral strategies are insulated against the market direction.” what is the meaning of this…Delta neutral means position not making money either market move up or down right? why we use delta neutral in our strategy ? is there any perticular time ? please help karthik ,,,,i am very confusing this word “delta neutral”


  38. K R Ashok says:


    In the money options has very high premiums. Why can’t I short slightly ITM and collect the premiums?

    • Karthik Rangappa says:

      Cause the chances of ITM options remaining ITM at expiry is high. You don’t want to be writing such options.

  39. NK says:

    I think the below statement is incorrectly framed. 1% move over and above the 2.2% will give ~75 points to Nifty Index which will increase the premium and the profilt should be calculated on this increased premium. So the sentence “profit of atleast 1%” seems incorrect.
    “Further if you want to make a profit of atleast 1% on this trade, then we are talking about a 1% move over and above 2.2% on the index.”

    Do correct me, if i am wrong. Thanks.

    • Karthik Rangappa says:

      Are you doing this calculation based on current Nifty prices? Anyway, let me check this. Thanks for pointing anyway.

  40. Pawan says:

    as banknifty is very volatile can we make this strategy on daily basis on opening for 5 points daily

  41. Rajiv says:

    Hi Sir, for may 7th french elections, there may be volatility predicted. So on May 4th (Thursday) by 3 pm can I buy NIFTY ATM CE and ATM PE for a long staddle (for may series)? and exit on early morning trade on May 8th (Monday) by 9.20 AM. there is a one day in-between buy and sell for the volatility to go up. is this a sensible trade set up. please clarify. Thanks.

    • Karthik Rangappa says:

      Yes, you can. But its best if you can close the position just before the event. I’m saying this purely out of my personal experience.

  42. Virochan Prabhu says:

    Do we have any site where we can see all fno stocks with its current volatility to understand higher n lower volatility stock to plan for straddle ? as its difficult to check stock one by one to understand which stock has less volatility

  43. Sai Sreedhar says:

    When you say “The volatility should be relatively low at the time of strategy execution”, which volatility will you refer to. When Put Option (Implied) Volatility increases the Call Option (Implied) Volatility Decreases and vice-versa. So how would it be practical to get both side strikes at low Volatility? Or are you referring to the volatility of the underlying itself, like when there is Bollinger Bands Squeezing and Ranged/Forming of Doji candle kind-of situation? Or is it the volatility of the overall market gauged by something like Vix?
    I was wondering if this is practically achievable?

    • Karthik Rangappa says:

      Sreedhar, I’m talking about the IV of a particular strike. All else equal, the IV of a call and a put for the same strike should be same.

      • Sai Sreedhar says:

        Ah, Thanks SO much for clarifying Karthik!
        So if I understood correctly, these are the conditions to initiate the Long Straddle:
        1. Strike of CE = SPOT = Strike of PE
        2. Delta of CE = (-) Delta of PE = 0.5
        3. IV of CE = IV of PE
        How much should we consider margin of error here – I mean 1% above or below the conditions should hold good or we have to consider more room for adjustment?

        • Karthik Rangappa says:

          Yes, most importantly, I’d look for the volatility. If you are going long straddle, then it’s best if the volatility is low and expected to go higher soon. If you are shorting a straddle, it’s best if volatility is at an elevated level and expected to go down soon.

  44. SANDEEP says:

    thank you karthik rangappa.
    and also SAI shreeder for sharing valuable knowledge.

  45. ZD2412 says:


    For the below point:
    “The volatility should be relatively low at the time of strategy execution”

    Please let me know how to find the volatility is high or low at the given point of time. Tried reading volatility chapter but couldn’t make out.

    Example, i have to execute the trade now, i need to decide based on the volatility to find the right time, how can i do this.

    Help much appreciated and the articles are too good.


    • Karthik Rangappa says:

      In such cases, you can quickly check the current implied volatility and compare it with the historical volatility. Both these volatilities are published on the NSE website, and I guess I have shared the links in the earlier comments.

  46. Priya says:

    Dear Karthik Sir,
    First of all thanks for this wonderful module provided by you. 🙂
    I have an issue regarding LONG STRADDLE, I’m asking with help of following example:

    On 1 March 2018, ADANIENT spot = 199.15. Thus, I decided to apply long straddle blindly 🙂 🙂 🙂
    Okay Jokes apart. Back to the point,
    I selected strike price = 200CE & 200PE. And, lot = 4000 & EXPIRY – 28/3/2018
    Buy ADANIENT 200CE = 10 premium paid
    Buy ADANIENT 200PE = 7.7 premium paid

    On 26 March 2018,
    ADANIENT 200CE = 0.1
    ADANIENT 200PE = 39.9

    (1) Can I close both these leg-positions before expiry?
    (2) Profit = (CE)+(PE) = (-9.90)+(32.2) = 22.3 Is it correct?
    (3) Can I close CE & PE positions in 1 day by taking profit of premium difference?
    (4) Is my Question No. (2) calculation is correct?

    Thanks Karthik Sir.

    • Karthik Rangappa says:

      1) Yes, you can close both the positions before expiry – in fact, I’d suggest you close this rather than keeping it open
      2) Yes, that is correct. Or you can look do this – you paid a net of 17.7 and if you square off you will get 39.8. Hence you make 22.3 as profit
      3) Yes, you can
      4) Yup.

      Good luck, Priya.

  47. Hari Haran says:

    @Karthik . Thanks for putting effort to prepare all these topics so new bees like me can an great understanding.

    How do u think this will effect trading options ?

  48. neel says:

    Message from NSE
    Dear, your traded value for 06-06-2018 CM Rs 240000.
    What does it mean i have to pay this amount?

  49. Anand says:

    I have one basic question, please consider below example

    BankNifty weekly expiry: 21June 26500CE
    Scenario 1: Buy Price: 50 Sell Price: 70. Profit = 20*40 = Rs 800/-
    Scenario 2: Buy Price: 50 Sell Price: 40. Profit = -10*40 = Rs -400/-

    Is the above profits correct? In your examples, we are completely subtracting the premiums paid. Please clarify

    • Karthik Rangappa says:

      Yes, you can simply take the difference between the buy and sell price of the premium, multiply it with lot size and get the P&L.

  50. Aksh says:

    When we buy a straddle. The strategy will no more be delta neutral when the market starts to move.

    If the morket moves up delta and gamma of the call option would go up. As the option will be moving from ATM to ITM. at the same time the gamma and delta of Put option wil be decreasing as the put option will be moving from ATM to OTM. which will result in net profit for every point the market moves.

    Same scenario with put option in case the market goes down.

    Am I right?

    If we apply the straddle for intraday or swing trade with a long expiry,Do u think it will be more benificial ? as the effect of theta will be less and both call and put premium will hold some value and will not expire at zero.

    This strategy is best suited when we expect the market to move a lot in either direction bcz of election result ,quaterly result, RBI rates, correction phase of market etc. If we expect the market to move substantially we should place the trade some time before we expect the maeket to move. As near the announcement or other event the IV will be high which will offset any gain which we may make. If we apply stradle before some time we expect the market to move we may even gain from high IV at the time of announcement. Am i right in thinking so?

  51. Aksh says:

    EDIT :
    When we buy a straddle. The strategy will no more be delta neutral when the market starts to move.

    If the market moves up delta and gamma of the call option would go up.

    i think long straddle works for banknifty as it is highly volatile and 200 points move is not a a big deal for banknifty

  54. Yazad says:

    Hi Sir,
    Thank you for these informative articles.. I just wanted to know how do you estimate the ‘implied volatility’ of a stock? Also for an index, is VIX the implied volatility?

    • Yazad says:

      In continuation to my above question, if implied volatility < historical volatility at the start of the month, then there is a high probability that this strategy will yield profit.. Is my understanding correct or am I missing out something?

    • Karthik Rangappa says:

      Yazad, this is a complex task and highly quantitative. Models such as GARCH (1,1) and GARCH (1,2) helps you estimate IV. Yes, VIX is the index’s IV.


    Sir, can this strategy used during election results?

  56. Santhosh says:

    I am proposing a hypothetical situation. I will short a straddle of the present month and go for long straddle of the next month expiry preferably after second half of the present month ( calender spread). I am expecting three things to happen.
    1. I will be benefitted by theta decay as the theta of current month will decay faster than next month. So range bound market will be desirable
    2. If there is any drastic increase in IV, i will still be benefitted as the vega of an option with more time to expire will increase faster than short month expiry option. Since I had gone long on next month expiry, I will be benefitted.
    3. If there will be a drastic movement on one side, one of my options gies ITM and I dont have to worry about the delta as the delta of deep ITM will be near to one irrespective of the time to expiry. Delta of deep OTM options will be negligible in both the cases.
    Even if it gives small profit, I am almost risk free.
    Please correct me if I am wrong

    • Karthik Rangappa says:

      1) Yes, the theta decay of the current month will be faster than the 2nd month
      2) This can be a bit tricky, your current month options can bleed. But this really depends on the way markets are position at that point and how other greeks stack up
      3) Agree, but this cant be entirely risk-free for reasons mentioned above. I’d suggest you plot this on excel and see the payoff.

  57. Santhosh says:

    1. Yes sir, you are right. Current month option can bleed high. I tried using sensibull builder. May be because of higher gamma. The rate at which the delta changes at current month may be higher than the next month. Because the IV was higher for far month options. However for me, this looks better than naked straddle/strangle!. It protects me to some extent from any black swan events. And price has to move significantly for me to incur substantial loss.
    2. I could not draw its payoff using excel as we are not certain about the options prices for the next month at the time of this month expiry. Hence used sensibull. Could not predict the volatility to use black scholes calculator. How I could do it?

    • Karthik Rangappa says:

      1) I agree, Santhosh. But a black swan event, by definition, is supposed to be extreme 🙂
      2) Hmm, I should have thought about it. B&S does not help you predict the volatility, you’ll need separate models to do that.

  58. Xavier Ghorkana says:

    Hello Sir,
    How to Calculate Implied volatility for stocks and Index?


    • Karthik Rangappa says:

      There are several models such as Arch (1,1), GARCH (1,1), which will help you calculate the implied volatility. However, this is quite complex.

  59. Harsh Singh says:

    Dear Karthikji
    I’ve few questions here
    1) Since we know if implied volatility increases price of options premium increases. But big doubt is that due to increase in volatility the index or stocks will fall, thereby reducing call options premium but increases put premiums. Isn’t this contradiction. Or is it so that increase in volatility only increases put premiums ?? Will call premium increases if market falls due to high volatility. Only one example of deep OTM call premium u’d shown in late August 2015 5% big market crash. Kindly cLear me this with some examples
    2) Can we implement OTM options long straddles ? In this can both put and call be slightly OTM equidistant from ATM during major events like coming elections results or two weeks before(if got such opportunity when time to expiry is long & low volatility) corporate results ? Although payoff structure, market direction, volatility and theta I’ll keep in mind…
    Thank u for giving time 🙂

    • Karthik Rangappa says:

      1) But big doubt is that due to increase in volatility the index or stocks will fall, thereby reducing call options premium but increases put premiums. Isn’t this contradiction —-> due to the fall, the delta plays a role and the premium of PE increases. However, the increase in volatility has an equal effect on both CE and PE, where in the premiums increase. This happens most of the times. Check section 20.4 –

      2) Yes, but be mindful of the payoffs.

  60. Manoj says:

    Hi Karthik,

    Amazing article..

    One question though..
    When we are talking about volatility in this, which one are we talking about?
    is it IV (Implied volatility) or VIX (India VIX)?
    And if its IV, how do you guage if IV would increase or decrease? does VIX has any relation to IV of each option?

    Many Thanks,

    • Karthik Rangappa says:

      We are talking about the IV, Manoj. You can use any basic B&S option calculator to extract this. Check this –

      • Manoj says:

        Thank for a reply Karthik.. Really appreciate it..

        Just a last time… it leads 2 questions for me then..

        1) Does that mean IV is separate value for each stock & Nifty and also differs by strike price and expiry?
        2) Does IV for each stock and Nifty have any standard gauge to assess if its low or high?

        • Karthik Rangappa says:

          1) Yes, IVs are different for each stock/strike/expiry
          2) Yes, volatility cone helps you figure this out. You should check out for this.

          • Manoj says:

            Hi Karthik,

            One query before actually jumping on it 🙂

            Suppose trader writes a call, lets say writes a call of strike price 12000 on Friday for next Thursday expiry (5 days to expiry).

            Now during week till next Thursday expiry,

            1) if spot moves above 12000 in intra-day, would it be termed as lost contract and call writer loses money since it touched above 12000 in intra-day?

            2) if spot closes above 12000 in one of the day before expiry, would it be termed as lost contract and call writer loses money since it closed above 12000?

            3) Only on expiry day if spot closes above 12000 then call writer lose money??

            Many Thanks,

          • Karthik Rangappa says:

            1) He may experience a notional loss, but then he has time till expiry
            2) Same as above
            3) Yes, he will.

  61. Satya says:

    Hi Kartik,
    Bollinger bands show volatility. Can we use that while creating a straddle?
    While creating a straddle should I check volatility of the spot or I should check for each strike(Call and put)

  62. Satya says:

    I am totally confused with the movement of option price. Right now market is 11673 up by 30points but both CE and PE are down. If I take a straddle then both are down. How the profit will come?

    • Karthik Rangappa says:

      Satya, this depends on the strike you’ve selected. Also when the volatility lowers, the premiums also come down.

      • Satya says:

        I saw your post in varsity regarding this. I was so much frustrated that day.
        There is many things to learn from market

        • Karthik Rangappa says:

          Markets are the best teacher and has many lessons for all, so we all end up learning all the time 🙂

  63. Satya says:

    Dear kartik
    I am a beginner to option trading and TA.
    Recently I learnt OI analysis to initiate a trade. It is fantastic. Now I am facing some challenges like analysing bank nifty. The OI change is so fast I couldn’t track and lost money heavily.
    I checked OI data from NSE INDIA.COM
    But the Oi data gets updated every 3minutes.
    Can u suggest anywhere I can check the OI changes every minute or less than that

  64. Satya says:

    I track OI data along with RSI, volume, MacD.
    Now after watching varsity trying for hanging man and hammar to catch the trend.
    But still I am not sure, if these set up are enough.
    Can u suggest a guideline

    • Karthik Rangappa says:

      I personally think the emphasis should be on the candlestick pattern and not really on the OI/indicators. The patterns reveal trends when they form.

      • Satya says:

        For trading prospective I get lot of noise in 1minute candlestick chart.
        Can u share the habits of successful traders.
        How do they choose a trade?

        • Karthik Rangappa says:

          That’s largely based on the experience of the trader, Satya. But yes, I do agree, 1 minute is a lot of noise. It is best to deal with 10-15mins for intraday if not for EOD candles.

          • Satya says:

            Dear Kartik,
            If i am following 10minutes candle, I am missing big moves like today. All big moves are over in a span of 10minutes.
            What should be the strategy.
            I want to learn the right approach.

          • Karthik Rangappa says:

            Well, the same big move can be in the opposite direction whipping out your gains. So at the end of the day, this is about figuring out the right balance between risk and reward. I still think 10 or 15mins works well for intraday. Maybe you should evaluate this over more trades.

  65. Satya says:

    Now I agree to your views regarding 15minutes candle.
    Please suggest the other combinations of indicators which I should follow

    • Karthik Rangappa says:

      Frankly, indicators should be secondary, your primary analysis should be based on candlestick patterns 🙂
      Anyway, apart from that, I like trading setups based on indicators such as Bollinger bands and ATR.

      • Satya says:

        Dear Kartik,
        I am using Bollinger band too. When it gets narrow, a breakout follows.
        Now if I take a straddle position, will it become profitable?
        Like yesterday bank nifty moved 500 points. In the case of yesterday, what would have been day end scenario?

        • Karthik Rangappa says:

          The position needs to be initiated when the band expands…with a hope that it will narrow down (reversion to mean). If you are following BB for options, then you should also look for the volatility. This is because BB deals only with the price but straddle is also dependent on volatility.

          • Satya says:

            Dear Kartik,
            I couldn’t follow your reply.
            What I mean to say that BB narrows just before a breakout either up or down.
            If I consider to take a straddle position intraday, during this narrow period, do u think it will b profitable?

          • Karthik Rangappa says:

            Ah, sorry…I didn’t get your question earlier. When the BB is narrow then it implies that the stock is at the mean. There are two problems here –
            1) The breakout (or expansion) can happen in either direction, which is still ok considering you are setting up a straddle
            2) The stock can remain in the narrow state (at the mean) for an extended period.

  66. Satya says:

    Dear Kartik
    Can u please advice when should we go for straddle and when we should go for strangle

    • Karthik Rangappa says:

      Straddle when you expect a sharp movement in the stock almost on an immediate basis but not sure which direction. For example corporate results of a company. Strangle (short) when you expect the stock to be range bound over the defined time period. You can almost always work with a long straddle over a long strangle.

      • Satya says:

        Everyday is a new day and everyday we come across cases like Yes bank or something else, which makes the market highly volatile.
        Then how do we judge the market whether range bound or directional

        • Karthik Rangappa says:

          Satya, the only differentiator is momentum. If you see momentum picking up across a wide set of stocks, then perhaps the market is setting itself in a direction. In the absence of momentum, it is range bound. You can start with this assumption.

  67. Satya says:

    Hi Kartik,
    I need a strategy for may in options. I am convinced that this is a very rare opportunity in equity markets. Can u help

  68. Satya says:

    Now I am learning candlestick. I have a doubt. If I am interested to take a trade in options, should I concentrate on spot candle or the strike candle

  69. Harsh Singh says:

    Dear Karthikji

    Straddles or strangles, according to theory, requires large move of market movement, large breakevens & perhaps other things into account like volatility, time etc. But what I’d seen in real trades are very different. I took many screenshots of different price actions, at different points & put that things on paper studies too from last 2 months. As u’d seen period of March is relatively low volatility months & Nifty shootup 1200 pts. April is high volatility months. My observations is that along with some questions many times on both “high & “low” volatility day there HAPPENED CONTRADICTIONS TO ABOVE THEORY.
    The gain in say call premium offset put premiums much before breakeven point happens. Both in nifty or banknifty etc.
    My question is
    I’m confused here why this happens & differ from theory, even strategy like bull call spread is showing different results from theory ?? Or is the above theory valid only for options holding till expiry day or is real time trading is different from theory… kindly feedback your experience for my doubt ?

    • Karthik Rangappa says:

      Volatility is the key factor for these strategies, Harsh. You need to assess where the volatility stands before initiating the strategy. This is more important than the directional move.

      You can hold till expiry, or do what most do – once the directional move kicks off, the square of the loss-making leg and ride on the winner.

      • Satya says:

        Dear Kartik,
        What is the ideal volatility level to initiate a trade

      • Satya says:

        Now if I check volatility, at a particular spot price, it is different for spot, PE, CE
        Which one to consider to initiate the trade.

        • Karthik Rangappa says:

          Yes, that is because each of these strikes has its own demand-supply dynamics. I generally look at the ATM CE option volatility.

  70. Raj says:

    Hello Karthik,
    Can you please help me to know this:
    Case 1: Low volatility and market goes up (bullish)
    I recently experimented long straddle when volatility is low (VIX) and at the rise, and buying CE + PE at the money (zero delta) works as expected.

    Case 2: Low volatility and market falls (bearish) ===> And here is where i see straddle fails at times.
    I see at times that CE loses more money than rise in PE, hence net result is a loss in long straddle.

    But again when market falls, shouldn’t the volatility increase, increasing the price of both CEs and PEs. Then why do CEs lose more value than PEs when market falls? Is long straddle not an ideal situation here in bearish markets?

    Kindly suggest.
    Thanks much

    • Raj says:

      Same as in Case (3) is also seen in case of high volatility and bearish fall. That is CE loses value more than PE.
      I know fall in volatility implies fall in premium. Shouldn’t CE and PE lose premium equal rate, rather than CE losing more than PE?

      Or in summary, strangle fails more often in bearish cases.

      • Karthik Rangappa says:

        Like I mentioned in my reply to your earlier comment, this depends on both Delta and the volatility, Raj.

    • Karthik Rangappa says:

      Raj, with the drop in markets, the volatility increases. With the increase in volatility, the options gain value. However, this depends on the extent of the fall and the extent of the increase in volatility. Sometimes it can so happen that loss in CE (attributable to Delta) is more than the expected gains in CE (attributable to volatility).

  71. Anshul says:

    Hi Karthik,

    First of all hats off to your amazing knowledge. I read your fundamental posts and now this technical stuff, you seem to know everything 🙂 and have put lot of effort to explain stuff in a simple way. Thanks for this.

    On quick question, Is it true that IV will increase in case of both breakout and breakdown? If thats the case consolidating stock will always benefit from long straddle assuming we are beginning of expiry hence insulated from Theta, isnt it?



    • Karthik Rangappa says:

      Thanks for the kind words, Anshul!

      In case of a breakout, I IV may actually drop. Yeah, with the passage of time, you will benefit from Theta decay.

      • Anshul says:

        Theta Decay will hurt the long straddle right?

        Also suggest me something, lets say IV is low (1st or 2nd quadrant), stock is consolidating and a breakout happens at start of the series. In this scenario can a long straddle be expected to make money?

        Since overall Vega and Theta are both against and only Delta favours the strategy hence does this mean that Long Straddle will work only when when breakdown happens?

        Getting confused with this stmt in the chapter — The market should make a large move – the direction of the move does not matter

        • Karthik Rangappa says:

          Yes, you can as the effect of theta decay is lesser at the start of the series. Here are two generic things to remember with long option strategies –

          1) Theta will have a -ve impact on long options
          2) Hedge against theta decay is more time to expiry…which means long options are best deployed at the start of the series.

    Hi kartik
    Now I want to go for straddle ( will buy both PE and ce) only for intraday. Let’s say I have a capital of 50k. How much exposure I will get for intraday straddle buy. Same question for intraday straddle sell.

    • Karthik Rangappa says:

      I’d suggest you check the margin calculator –

      • Satya says:

        I am not able to understand span. Because there are 2 options. One is buy and another is sell. But in my case I want to buy both buy PE AND CE.
        And want to sell I PE AND CE
        Roughly some broker are giving 20x, 50x margin for intraday Index trading.

        • Karthik Rangappa says:

          Satya, to buy options you need to pay up the entire premium required. If you want to hold the short position intraday then yes, you will get some margin advantage, but for all the overnight position you will have to pay the entire margin/premium required. The broker will have to pay a penalty in case of a margin shortfall from the client’s side.

          • Satya says:

            Kartik, that’s what I want to know. I want trade intraday straddle with a capital of 50k. How much multiple I will get exposure. How to know it and whom to contact?

          • Karthik Rangappa says:

            Satya, to know the exposure, you will have to add the stock/index name on the span margin calculator and see the margins required. Else, I’d also suggest you call our support desk for this.

  73. Satya says:

    Today I just saw my Zerodha page and it is showing that nifty at 12032 up by 209 points.
    Vix is low at 13.9
    Can u please help me to understand what is this. How come it is showing a growth of 209 points

    • Karthik Rangappa says:

      Y’day was mock trading session, Satya. Mock trading sessions are for brokers to test their systems. So the values you saw were all random.

  74. Satya says:

    I want to go for straddle. Which expiry should I choose

  75. Satya says:

    What is your opinion. I think this is a perfect point to enter a straddle. Vix is all time low. Some news and events including budget is on monday. Text book copy paste position.

    • Karthik Rangappa says:

      For a long straddle maybe. But I’d have been more convinced if the volatility was higher to a short straddle.

  76. Satya says:

    Hi kartik,
    This market is still a puzzle. And many things to learn.
    What I observed that selling a straddle doesn’t work in a trending market. It works only in a range bound market.
    Can u guide regarding choosing the strike price. For intraday straddle

    • Karthik Rangappa says:

      That’s right, in a trending market you need to be net long delta (if the trend is bullish) or net short delta (in the trend is bearish). Delta neutral works best when the markets are not trending.

  77. Satya says:

    Where to find greek values Kartik! Including delta figures

  78. Satya says:

    Day before yesterday, nifty had a bearish candle. Market was waiting for direction to move up or down. International concerns pushed market below. And all indicators were negative. But market sentiment changed yesterday and it went up 100 points.
    In this scenario, let’s say yesterday morning, what could have been done to anticipate the market movements either up or down!

    • Karthik Rangappa says:

      Satya, it is tough to take a call. Most often the cues come from the price action (charts), but then when there is fundamental news, then that has a bigger impact on the market’s direction.

  79. satya says:

    Can you please give example

    • Karthik Rangappa says:

      For example, when the budget is around the corner (fundamental event), the candlestick patterns do not play a part.

  80. Satya says:

    Kartik, can u plot a sale with ideal situation.
    Range bound market
    Delta neutral straddle
    Volatility around 17

  81. PL Subramanian says:

    I have reading your varsity article. They are very good and flow is interesting.
    I have a question
    How would I manage margin? Zerodha or any broker holds to a big amount as margin. If I carry over a position say Put Spread to next day my money will be held? Is there any way to handle it. Zerodha had products BO and CO but that works for intraday only.. please advise

    • Karthik Rangappa says:

      If you intend to carry forward a position, then you will have to have the entire margin required for it. In fact, any shortfall in the margin, the exchange will levy a penalty on the broker.

  82. Satya says:

    I mean to say an example of an ideal scenario where we can take a position.
    Like described in text book

  83. Satya says:

    I have a query. Today nifty closed to 11950. Then why PE and CE for 11950 became zero. What is the rule. Can u please elaborate on this topic

    • Karthik Rangappa says:

      You must be looking at the weekly expiry. Options that are out of the money and at the money expire worthless, hence the value was 0.

  84. Satyam says:

    Sir Please add other strategies also like iron condor and iron butterfly

  85. Satya says:

    I have a query regarding Friday 12th July nifty movement. There was a movement of 100 points. Most of the time nifty stayed above pivot. But I couldn’t identify a single candle which was a clear buy. May b my limited knowledge. I am following 5minutes candle.
    Can u please check and elaborate the candles to understand the move.

    • Karthik Rangappa says:

      Satya, if there was no trade opportunity, then it is fine that way. There can be a movement in the market, but if the market does not present you with an entry opportunity, then there isn’t much that you can do.

  86. Satya says:

    Dear Kartik, my question was “Did i miss any candle?
    I am a student, therefore I want know, if my observation was right or wrong.

  87. Francis says:

    Hi Karthik,
    First of all Thank you for an amazing series of modules in zerodha varsity.It gave a lot of insight to newbies like me.
    My question.
    1)Is it a good idea to buy a long call option with 1 or 2 years of expiry, instead of buying stocks/etfs ,if it is available at low volatility.
    2)And in case if market direction reverses buy a put option to hedge it on a short series like monthly expiry,still holding the long term call option.
    3)Is the overall strategy a good one.
    4)is there any other factors to be considered to make it a more safe bet.
    note:- I work in U.S. and as far as know long term u.s etfs and stocks options have good liquidity as compared to nifty.

    • Karthik Rangappa says:

      1) If you have such a long term view, you’d rather buy the stock right? Anyway, if you do get the pricing right, then maybe its worth it. I’ve never explored this much by the way (simply because we don’t have such a market in India)
      2) The costs would go up, not sure if you will have any added advantage after considering the cost/tax benefit
      3) Yes, provided you get the pricing, tax, and cost angle right
      4) Frankly, I can’t think of any now, have to spend some time understanding these long-dated option contracts (also called leaps)

  88. Karthik says:

    Hi Karthik,
    This maybe offtopic but I don’t know where to ask this.
    I am confused in executing the orders.
    As I m doing intraday, I want to act quick and square off my position..

    For eg: I buy 200 lots of banknifty option at 150. When the market goes up, I want to sell only 100 lots at 160 and hold other 100.

    For this, how to do. Also, I need to put stop loss too.

    • Karthik Rangappa says:

      Since you want to position size, your only option is to do this manually on Kite. You can do this from the position tab on Kite and sell the desired quantity.

  89. Karthik says:

    Ah thanks.
    So, I need to modify and exit the position right?
    As I put sl sell order for 200 quantities
    Do I need to modify that as 100?

  90. Maaz says:

    The speed at which one option contract hits the stoploss is not the same at which the other hits the target. Hence, the straddle is broken off at one end and before the target price is achieved at the other end, the market turns again, resulting in loss in both.
    How to deal with such a situation.

  91. Maaz says:

    Umm…but say I buy the call options at the start of the month and the straddle breaks off on the 15th day wherein the target is not hit but the stoploss at one end is hit, then should I straddle again till expiry? Or is long straddling a good strategy when the option contract nears expiry (but then again, the closer the expiry, the worse it is for call/put buyer) I’m confused.

    • Karthik Rangappa says:

      Hmm, near to expiry I’d prefer a short straddle as opposed to a long straddle. By the way, if the straddle breaks, you can adjust the straddle with the new ATM strike.

  92. Satya says:

    Hi karthik,
    I am trying to improve my analytical skills and now what I found that candlestick are the best ones.
    Then should I buy naked calls based on patterns or I should still follow the different strategies to trade option like sell a strangle, iron condor etc.

    • Karthik Rangappa says:

      Traders base their naked option trades on candlesticks, no harm with that. It is just that you need to build an appetite for risk.

  93. Satya says:

    Dear Kartik, it is true that I should have appetite for risk, but what I found that in a day market gives several safe opportunity to trade where risk is minimum.
    But I am finding it difficult to choose the right stop loss in option.
    I want to elaborate. Today I guessed that nifty has a strong resistance at 12150. Hence I purchased 12150pe @25.
    But to minimise the risk I purchased bo with sl 5 point down with trailing sl of 1 point.
    Before moving up to 50 it gave sideways movement for some minutes and my Sl triggered at 24.
    I wished if I can know the 12150 pe price at 12150, then I could have given a proper sl.
    Can u suggest how to find out the price of option at underlying price at upper or lower side.

    • Karthik Rangappa says:

      Satya, this is common and unfortunate. The only way to avoid this is to have a deeper stop loss with proper reasoning behind it.

  94. Satya says:

    Hi kartik,
    Thanks for your reply. Can u advice, how can I get the probable option price at a particular underlying price.
    Nifty at 12056
    I want to know the price of 12100 pe (now [email protected]) will be when market will reach 12010.
    Any website or any formula to get that. Greeks will be required. I don’t have access to Greeks. I need to know this to decide my target and SL

    • Karthik Rangappa says:

      Satya, that depends upon multiple factors. This non-linearity is what makes options difficult to understand.

  95. Umang says:

    Hello Karthik,
    I have some doubt regarding the long straddle strategy. It would be really helpful if you could clarify it.
    Today i have initiated long straddle in YESBANK when spot was trading around 69. I bought DEC 70 CE at Rs7.60 and DEC 70 PE at Rs11.15.

    Currently YESBANK is trading at Rs66 but DEC 70 PE is at 11.00 where as DEC 70 CE was at 6.10

    My question is when spot price decreased from 69 to 66, PE option should have increased in value where as CE option should have decreased.
    Can u please clarify what could be the scenario which didnt let PE option to increase in it value.
    Thanks in advance 🙂

    • Karthik Rangappa says:

      Umang, along with the directional movement of the price (delta), you also need to watch for the volatility (vega). With the increase in the volatility, the premium is also supposed to go up and vice versa. I suspect the volatility dropped at the same time, hence the slight decrease in PE premium.

  96. Satya says:

    I am passionate about options and want to learn
    Please guide me

  97. Satya says:

    Dear Kartik
    Please guide me How to trade in trending market

    Today I checked at 11am and saw market is falling. Market halted at 12020. I thought it will respect 12020 and will return. I bought CE Which was against the trend. Market again came down. And I booked loss.
    What is the right approach to identify a counter trend or supporting trend.
    I am confused. Need help

  98. Kishor Barde says:

    Very informative and useful from Profit as well as risk assessment point of view….Thanks Varsity team

  99. Manvendra Agrawal says:

    Hi I have entered a Long Nifty Straddle today for trading long volatility for tomorrow’s budget. Please suggest an appropriate exit strategy/timing. I am confused whether I should exit at tomorrow’s closing, before budget announcements or after the announcement. Please help.

    • Karthik Rangappa says:

      The IVs are likely to drop post budget, which will have a -ve impact on your long positions. Hence its best to close the position at the start or early stages of the budget speech.This is my personal opinion though 🙂

  100. Kishore Ranjan Das says:

    But let me ask you this – if the direction does not matter, what else matters for this strategy?

    Ans: The PROFIT.

  101. Sachin says:

    Hi Karthik,

    Bear with me as I am repeating one of my earlier question.

    If I take position with this strategy, then I can skip SL and exit both positions, even before contract expiry, at a point when I’ve enough profit or reached acceptable loss. Correct?

    As usual, thanks for all your knowledge sharing!

  102. Akshay Malhotra says:


    I back tested long straddles/strangles on NIFTY and found that they almost always lose money when NIFTY goes up (due to decrease in Volatility) and make money when NIFTY goes down (due to increase in Volatility). That would make them not exactly direction neutral.

    Under what condition will these strategies be really delta neutral?


    • Karthik Rangappa says:

      The thing, when you set up the straddle or strangle, it will be delta neutral or direction neutral. However, as market moves, it wont be. It has to be constantly adjusted to maintain the neutrality.

  103. Akash says:

    In the end of this chapter, it is written “Download Bull Call Spread Excel Sheet”. It should be “Download Long Straddle Excel Sheet”.


  104. Akash says:

    Its my suggestion that Zerodha should have a platform on Virtual Trading also that covers all F&O stocks and indices and NOT ONLY the Nifty. There are certain brokers that offer virtual trading but for Nifty only. Virtual Trading available at Sensibull is for paid members.


  105. Ritesh Jha says:

    Hi Karthik, wanted to know your views on how to appropriately encash the change in volatility keeping an upcoming event in mind.. for example ICICI Bank results are supposed to come out in first week of May, volatility may increase during that time.. what would be the right entry and exit points for this event?

    • Karthik Rangappa says:

      If you expect –
      1) Volatility to increase – buy options
      2) Volatility to decrease – sell options

      Everything revolves around this.

  106. Sajith says:

    Brother i have one doubt u are saying buy a one lot.ok but one lot in nifty is ltp is 15 means i have to pay 15×75=1125 or just 15

  107. Sajith says:

    Brother i cant understand anything easily its so tough to understand.but i like to trade.i am new for share market.what should i do now?

    • Karthik Rangappa says:

      Please do read through and if you have any question then let me know, I’ll try and help you to the best of my ability.

  108. Pratik Pravin Marathe says:

    Sir , if Bank Nifty is so volatile , why don’t everybody just use the long straddle to earn easy money. It could be a good strategy for daily earning on Bank Nifty right ?

  109. Naveen says:

    I was wondering how would the straddle profit/loss chart look like before expiry based on price movement of underlying asset.

    For instance :

    Today’s Nifty50 closing price: 9553

    NIFTY MAY 9500 PE : 295
    NIFTY MAY 9500 CE : 350

    Suppose in next 10 days nifty moves to 9000. (Assume Implied Volatality remains same.) If I squareoff the positions at the end of 10th day will I still lose money?

    1) Delta neutrality.
    2) Volatality remains same.
    3) Theta decay

    These will make sure I loose money. Or am I missing something?

    • Karthik Rangappa says:

      If you square the position before expiry, what matters is the difference in premium. You can anticipate the change in premium though, I guess Sensibull has this option on their platform.

  110. Chirag says:

    Can I set up straddle to any strikes other than ATM? If yes, how to identify best strike to setup straddle ?

  111. Manjunath says:

    Hello Karthik,
    I simply get amazed by the way you simplify things. If you want to read the same concepts from a foreigner author(Infact I’am reading one now) he will explain in 30 -50 pages by the time you finish it off, you would have completely lost.
    I have few questions related to volatility. I am sure you will enlighten me on this particular topic.

    1. Volatility can be any number, to know whether it is high or low, i need to compare how it was historically. For nifty, i can check and volatility ranges between 10 – 38(ignoring what happened in last few months where VIX shot up to 80+. I hardly see IV below 35 for index options these days. does it really make sense to go for straddle? I agree that IV goes till 60, but above 35 IV is at the extreme end. how can i compare IV for a stock?

    2. For 1 point increase in spot, how much does volatility increase? Let’s assume for the sake of discussion,just like delta, it is 0.5. Now, spot increases by 10 points, so volatility for CE will increase by 5 points. For put, volatility decreases by 5 points. That means, call premium will increase by 5rs and put premium will decrease by 5 rupees. am i correct here?

    3. Besides spot, what affects IV? I heard and read that IV increases based on market expectation. but how do we quantify market expectation? As you mentioned above, IV shoots up during events, but how much does it shoot up? since options are nothing but math formulas, there should be a way to calculate how much volatility shoots up

    4. Premium for options are calculated using Black Scholes model. Once we get the premium, we treat IV as unknown and derive from same BS model. I am not getting this point. how can we derive premium first and use that premium to calculate IV?

    I some confused w.r.t IV. please shed some light on above points.

    • Karthik Rangappa says:

      1) 35 can be the new normal, so as the market dynamics change, look for a change in pattern 🙂
      2) This is captured by Vega i.e. the change in premium for every % change in volatility
      3) The speed at which market is moving is what determines IV. There are quant models to predict this, check for GRACH(1,1) volatility models
      4) B&S is not just a premium calculator. It can be used to calculate IV also.

      Hope this helps 🙂

  112. Manjunath says:

    Thank you Karthik,

    Let me check on GRACH(1,1). Like delta, do we have any range for vega?

  113. Apu says:

    Thank you, Sir, for understanding it so clearly keeping volatility and time in the perspective…
    Any book you would like to recommend on option strategies ?

  114. Apu says:

    Thanks … Downloaded the pdf version 🙂

  115. Yets says:

    Hi sir,
    First of all Thank you so much for Varsity. I mostly find the answers of my doubt. Every morning I read 2-3 articles of Innerworth-Mind over markets and its very helpful to improve the thought process on any trade. It taught me to control the emotions over market.

    I wanted to request you something, It would be great if you can write something regarding predicting market fundamentally with option chain like what type of events can affect market in positive or in negative ways. How to understand market sentiment with surrounding clues. And how can we read option chain effectively to get the confirmation of our sentiments (bullish or bearish view). People always says if you have bullish sentiments then buy call or use bull spread or any kind of that strategies and if you have bearish view then use related to that strategies but no one taught how to make those views and decide the strategies accordingly.

    Will be very helpful if you guide us something on this.

    • Karthik Rangappa says:

      Thanks 🙂

      Also, thanks for the feedback. I will try and put up something on this as and when time permits 🙂

  116. Yets says:

    Thank you. 🙂

  117. Anil says:

    Hi Sir,

    Nifty jul 10800 ce at 199
    nifty jul 10800 pe at 227 7

    Now if I buy 10800 ce in one dmat account and sell 10800 pe in another demat account
    I get 227 premium and I am paying 199

    In this case I am not seeing any loss situation. Can you clarify ?

    say market is below 10800 199 gone in one but I got 227 in another so 28 rs profit here

    say if market has clsoed at 10900 100 is loss to seller but since I have received 227 still I will be in 127 profit

    I see in all scenarios positive pls clarify

    • Karthik Rangappa says:

      Anil, no need to take this trade in two different trading accounts. You can initiate the trade in the same trading account. Yes, as long as the market moves in any direction, you will make money. However, if it stays at 10800, you will lose money on this trade.

    In long straddle strategy,one need not to worry Abt volatility when date of expiry is near… that time directional move on either side only matters?

    I am trying to contact zerodha helpdesk but it’s saying ‘currently no person’s available to contact’.
    Can you plz help?

  123. Neil says:

    Hearty thanks for preparing such a enriched study material, hardly any other one match it, the beauty of this literature is simplification of content in such a way , even a beginner can understand. Definitely Zerodha , deserve a big pat for the lovely work helping budding traders in a big way.

  124. Siddhant says:

    One question. This strategy and all other strategy teaches us theory about profit and loss with strike price and instrinct value. But if i am not wrong in the practical market we mostly trade with premiums only. So will this strategy work if we trade with premiums. And will this work if we trade with premiums irrespective of waiting for the expiry.

    • Karthik Rangappa says:

      That’s right, practically speaking you only trade the premium, but you can also hold these positions to expiry as well. The logic remains the same.

  125. Piyush Parmar says:

    Ideally the strategy should work either in favor of CALL or PUT based on the direction of the market but this is only good in books, in practical this may not work as expected.
    Today (4th Nov 2020) Banknifty moved up by 0.45% between 9:15 AM to 14:15 PM BANKNIFTY 25600PE moved DOWN by -54.17% as expected but interestingly BANKNIFTY 25600CE also moved DOWN by -20.08%?? Trying to understand how the CE and PE of the same strike price 25600 for same expiry would move in the same (-ve) direction while the underlying is moving up? No doubt buying a straddle in this case would have resulted in loss anyways.

    • Karthik Rangappa says:

      Piyush, this is quite common for both CE and PE Premium to lose value when the volatility drops. The resulting gain in either PE or CE is not restricted to books, it happens if you hold to expiry 🙂

  126. Prathamesh mallya says:

    Dear Karthik Sir,

    Your explanations of options are way simple. I have never touched Greeks, because i could never understand it. You really made it simple through the NSE webinar as well as the VARSITY lessons.

    How can long strangle be deployed taking in to consideration the high premiums of ATM call options in gold?

    It is only beneficial when the premiums are superb low for the call as well as put option for you to breakeven easily. Please explain ?

  127. Ashish says:

    Hi Karthik,
    Even if premium prices drop, we can still make profit by selling at expiry. We just need one large move(around event), Right?

  128. Gautam says:


    Some confusion in my understanding. Once I have bought a CE or PE at a particular price, how does it matter if the Geeks change unless i buy additional options for adjustment. If i dont buy adjustment options, then geeks dont matter. Pls clarify.

    • Karthik Rangappa says:

      Lionel, please stop using CAPS to type in the query, it is very difficult to read especially when its such a long query.

      1) Yes
      2) Yes, an increase in volatility has a similar impact on both CE and PE

      A) Yes, but the trade has to pan out in your favour
      B) Yes, you can. Short is an expiry strategy.
      C) Yes, varies based on the market

    Hi Karthik,

    Nifty went from 14433 to 14281 from 15th to 18th which is just two trading days.
    What I found is If had bought 14400 CE and PE of 28 Jan exp on EOD on 15th, It would have cost me 250+186.15=436.15 and on the next trading day EOD after Nifty dropped 152 points these same options were trading on 139.85+282.1=421.95 making a -14.2 loss despite a significant movement by Nifty. The change of value of CE (139.85-250)=-110.15 is much more than the Change in value of PE(282.1-186.15)=95.95.

    If you can explain how and why this occurs it would help a lot.

    • Karthik Rangappa says:

      Karan, the reason for the inflated premium is the higher volatility. Higher the volatility, higher is the cost of the premium. When volatility drops, so would the premium. At times, the effect of volatility (vega) is higher compared to the underlying move itself.

  134. LIONEL says:

    What should be the preferable order type while executing Long straddle strategy, whether it should be limit order or market order; because if we place a limit order it could happen that due to sudden movement in one direction ; either CE or PE order get filled and the other one remains untriggered ?

  135. Rajat pahuja says:

    hello sir,
    by volatility you mean index vix or strike iv ?

  136. Ganesh Patel says:

    Hi Sir,

    I applied this strategy on budget day and the next day.

    Worked wonderfully!!!

    Thanks a lot 🙂

  137. santonu says:

    I observe that stock price of TCs, infosys, Tata steel etc make strong move in one direction after their quarterly result and this long straddle is ideal strategy for these events. TCS announces their result after market hour and guide me which would be better option for someone to initiate the strategy.
    1. Taking the position just before market closing as premium would be lower, no fear of time decay though we would not get the benefit of volatility but strong one sided move may give us good profit
    2. Taking the position just few days before to get the benefit of increased volatility . But this would be little bit expensive and time decay factor would be there

    • Karthik Rangappa says:

      1) Yeah, before the event, ideally at least a day to ensure you capture higher premium
      2) The play is on losing the volatility premium and not really theta

  138. ASHIS says:

    Sir, What I have noted is that when market reacts significantly to certain events and if the long-straddle has been initiated before the spike in the movement and the volatility, better to square off in profit than to hold (for retail traders). Eventually, the euphoria/ desolation will die down and premiums will collapse. That will have serious adverse impact a long-straddle guy ‘coz he’ll be bleeding from both the ends.

  139. VIDYADHAN GEDAM says:

    Dear Sir,
    I trade only on Wednesday and Thursday in index.
    I think this strategy is best on weekly expiry day.

    I have some questions:-
    1. For index should we see VIX or IV of ATM strike.
    2. Your example id showing VARIATION in ask and bid price of CALL (equal) and PUT(large gap).. is it matters.
    3. What is the best time to execute this trade on expiry. Is it when both call and put premium reaches same value. Most of time one of them shoot up…

    Thanks in advance,
    Vidyadhan Gedam

    • Karthik Rangappa says:

      1) Both are ok to use, I’d prefer the ViX
      2) Not much
      3) Yes, preferably when the premiums are more or less equal

  140. Devashish says:

    I have noticed that you rarely mention setting a stop-loss/targer on options trade. is there any particular reason for it, how should one set stop-loss on options.

    • Karthik Rangappa says:

      Not really, you can set SL based on the underlying prices. I’ve discussed this in the comments I guess. Personally, I prefer to keep like 40-50% SL on the option premium.

  141. AYAN MUKHERJEE says:

    Wonderful explanation.

  142. Shreesha Innanje says:

    Hi Karthik,

    How to calculate target date P&L ? I know my P&L on expiry but what to know to how to calculate for target date.
    Let’s say I execute this strategy on 1st of month, how to develop a table of P&L for upcoming days corresponding to spot prices respectively. Sensibull bull gives “on target date” data in strategy builder but what is the formula if I want to put it in excel ?


    • Karthik Rangappa says:

      I’d suggest you use Sensibull for this, they have the facility to showcase the P&L before expiry.

  143. Anil Pandey says:

    Excellent explanation.
    Thanks so much sir.

  144. sonu sharma says:

    Sir, in scenario 1 , u consider that IV 400 but as per option chain it is 15.08 . Please clarify it.

  145. Atul says:

    Hello Sir,

    For implementing long straddles/strangles before quarterly results or rbi events or budgets, when is the ideal time to initiate the strategy? 5 days/10 days before the event to gain on the IV rise, keeping in mind the time till expiry.
    Naturally all IVs rise before events

  146. Atul says:

    Hello Sir,

    Lets say initiate a long strangle 5 days before.

    How much IV do I know said stock will gain? How does one even know that?
    And when should one square off the position, post result or before the result?

    • Karthik Rangappa says:

      That’s hard to estimate, Atul. Although things like Volatility cone can help you get a perspective on this.

  147. Santosh says:

    Hello Sir,
    You have mentioned that volatility rises before the event and crashes right before/after the event.

    Couldn’t I purchase a strangle 5-6 days before an event, watch IV rise and then sell right before the event?

    • Karthik Rangappa says:

      You can. In fact, you can reverse the positions before the event and buy it back post-event. Check how this works on paper a few times before you actually trade it. Good luck!

  148. Tushar Kumar says:

    Is it necessary to buy straddle at ATM strike price
    Ex- if Banknifty opens at 35500, ATM would be 35500pe and 35500ce, but can we buy 35200ce and 35200pe.

    Your reply would be life saviour for me.

    • Karthik Rangappa says:

      It’s best if you can buy it at ATM. But like all things in trading, these are not rigid rules.

  149. priyanshu soni says:

    what can be the minimum amount required to start trading in option buying…

  150. Abhijeet Durge says:

    Stocks aren’t generally liquid. Say if you pick this strategy for Hero Moto Corp…the current month is Aug 21, there are mixed signals when it comes to directional move (monthly long, weekly and daily short), volatility has dropped after earnings announcement, IV of September is low (more or less similar to Aug), IV is less than historical volatility. So if I want to deploy this strategy or long iron butterfly, liquidity would be a big problem. Add to that European Options vs American Options problem. Also please explain exit strategy for example exiting which legs first in case of profit or loss.

    • Karthik Rangappa says:

      Some of the stocks are liquid, but yes, generally speaking stocks are not as liquid as the indices. Mixed singles is a problem if you are following too many indicators. Follow a few in which you have the highest conviction. European vs American is not a problem 🙂

    how to buy call and put option at one time throght streak on tlhursday

  154. Trading Professional says:

    Wonderful Chapter.

    I performed back testing on this and it works quiet well and in this way we can safeguard capital instead doing naked options.
    Can someone throw some ideas where/ when exactly we need to close positions. Do we need to close both the positions same time or we need to close one position and average the other position and close with minimal profit/Loss . Kindly share your ideas please.

  155. Trading Professional says:

    Thank You for the reply sir.
    One more small question Sir. I purchased call option and put option premium at the same price ( Rs.125 ) for Long Straddle Strategy.
    I initially saw both the premiums on Green. How can we understand this scenarios?
    Majority of the times net P&L of both the premiums are minus. Do we need to wait for a breakout/breakdown and then need to close both positions irrespective of same day closing ? Can you please guide.

    • Karthik Rangappa says:

      When volatility increases so do the premium of options regardless of the call or put option. I guess the volatility increased after you bought these options, hence the premiums.

  156. Trading Professional says:

    Thanks for the reply Karthik Sir.
    In Long Straddle scenario, when we have a Call Option and Put Option at same premiums, then irrespective of VIX increases or decreases, the ney P&L will be in positive right. ( I assume increase in VIX from 19.2 to 20.5 increases PE premium and in the same way if VIX decreases from 19.2 to 18 it increases CE option right ) . Please correct me if my understanding is wrong.

    • Karthik Rangappa says:

      If its just the volatility increasing, then yes. But chances are that your Call option will lose premium.

  157. Shrikant says:

    Dear Sir,

    Thank you so much for putting your valuable time to create new generation of traders from INDIA by providing this valuable and immense knowledge.

    I have implemented this strategy and have some question wrt long straddle.
    1. How to find the volatility of any FNO stock to implement this strategy.
    2. Normally before events volatility shoots up so weather stock price always go up or it can go down also?
    3. What are chart patterns by which we can say volatility is going to shoot up?
    4. Can you suggest any indicator to identify the increase the probability of trade?

    Just to inform you, I have executed this strategy on stocks.
    Just before day ends (3.20-3.30) I buy long straddle and on next day when market opens I sell straddle (9.15-9.20). Does volatility will always be high in the first 15mins?

    • Karthik Rangappa says:

      1) You can use the ‘=stdev()’ function on the returns time series, have explained in the volatility chapter in the previous module
      2) No one can predict this 🙂
      3) No chart pattern, but you can check out the Bollinger band and ATR indicator, these are based on volatility
      4) No indicator as such. But you can backtest the strategy that you are using to figure out the odds

      Generally, the volatility is on the higher side at market open, but this is just an observation, not backed by data.

  158. Prachi M says:

    Hi Karthik,
    How can we place a trigger on the underlying stock price to sell off both the CE and PE options at once, once we observe good profit payout has accumulated? Is this possible instead of placing GTTs on the individual option prices?

  159. Naval Singh says:

    Very well explained.Would try to implement.

  160. Sri says:

    Hi Sir, where to get chapter 10.5

  161. Prabhu Krishnan says:

    Dear Karthik, I’ve below query help me to understand

    Assume I initiated the Long straddle when the nifty is at 17000 ATM and after I initiated it was very bullish

    1. Say for example nifty moved from 17000 to 17500, so my question is when it moving should I stick with the 17000 strike(ATM to ITM) or based on the move should I keep shifting the strike (assume I’ve enough margin)

    2.And also after I initiate the long straddle, if the view is bullish and the overall delta would be in positive and same for downside move but it won’t be the neutral once its started moving, is this correct ?

    • Karthik Rangappa says:

      1) You can shift strikes, but doing this continuously increases your costs
      2) No, it won’t be neutral. Delta will change as and when the underlying price changes.

  162. Prabhu Krishnan says:

    Thanks a lot karthik 🙂

  163. GOPAL LAHOTI says:

    Hello Sir, Pls clear my doubts:-
    (i) If volatility increase then market decrease and vice versa ?
    (ii) How to estimate when will be the volatility decrease so that we implement our long straddle strategy ?
    (iii) In previous module, u said the slow the market goes in upward direction, the faster time it takes to move downward and here in this module u said Call premium speed is faster than decrease in put premium if market moves in upward direction and vice versa ?
    (iv) This strategy should be applied only if there is any result, event, election etc. Right ?
    (v) In previous comment u said exit before event then how we capture the movement at the time of event and as u said long straddle is only for movement
    (vi) Suppose expiry is on 28th April and result/election is on 25th April so If I implement long straddle strategy on 22nd April than THETA also play an important role at that time which result into may be loss. ? Then what we do in that case


    • Karthik Rangappa says:

      1) Usually yes. But there are times when markets increase and volatility also increases
      2) You can check the current volatility and compare it with historical volatility to get a sense of what is likely to happen.
      3) I said that in the context of option writing
      4) YOu can apply this otherwise also. For example when you expect markets to remain flat, you can deploy the opposite of this
      5) By staying long 🙂
      6) I’d suggest you apply the reverse of this.

  164. GOPAL LAHOTI says:

    Sorry Sir, Can u pls elaborate point no. 5th and 6th.

  165. Sagar Gandhi says:

    Can we use implied volatility percentile as to know wheather volatility is high or low ?

  166. SARAVANAN says:

    Wow. i learned much much better about Straddle Model. The way in which explanation given is give as a live tutor.
    I keep learning from Zerodha.

  167. Ashutosh Ghuley says:

    In this module everywhere you say that we have to hold our strategy till expiry. Do you mean 3.29 pm or what?

    • Karthik Rangappa says:

      You can hold it till the expiry day and if the position works in your favor you can let it expire as well. But generally its a good idea to close position before 3 PM on expiry days.

  168. arun prasad says:

    Hello sir
    Is it true that stock options trading more risky than index option if it expired in the ITM. Then one have to settled the either by paying all the amount of the shares or if you are buyer of the option ; you have to buy all the stock offered by the seller.

  169. Sitesh Kumar Barik says:

    Hello Sir,
    1) if suppose Today TCS CE ATM strike has Implied volatility- 16 and PE ATM has implied volatility of 19. In this case which IV to use to compare with historical IV to find out if it is in lower side or higher side. I means I will consider 16 or 19 ??
    2) kindly mention the formula to find historical volatility with which I will compare the current 16 or 19 .(point no 1)

    • Karthik Rangappa says:

      1) Ideally the IV for CE and PE should be the same. But they differ due to market dynamics. I’d suggest you go with the conservative approach. For example, if you are looking at writing an option, consider IV at 16 and if you are looking at buying consider IV @ 19. But if the difference is just 3%, it should not really make any difference.
      2) I’ve explained that in the previous module.

  170. Sitesh Kumar Barik says:

    Thank you sir for your previous reply which helped me a lot. kindly consider my below doubts.

    suppose TCS is currently at 3000 .
    Implied volatility of ATM-CE is 28 and ATM-PE is also 28
    I observed historical volatility is 35. But I want to short 3200 CE which has implied volatility of 40.

    so before shorting 3200 CE, should I compare historical volatility (35) with ATM IV (28) or with 3200 CE (40) which I want to short.

    • Karthik Rangappa says:

      Ideally, you should compare the strike’s IV with HV. But the 3200 CE may not reflect the accurate IV due to lack of liquidity (this may not be particularly true with TCS), but generally OTMs dont. Hence ATM is a generalization.

  171. Mohit K says:

    Hey Karthik!

    1. I implemented a long straddle with bank nifty few days before RBI policy declaration on 8 june 2022. VIX was 20 which I believe is not high but before the announcement the volatility remained same. I believe RBI policy declaration is a pretty important event. Was that because the event was already factored in the current price?
    I know that for a long straddle to work all the points should be ticked but I expected at least the volatility to work in my favour. Similarly, as volatility did not increase before/during the event it did not fall after the event.

    2. Any pointer on gauging the change in volatility better?

    3. Also it appears, to implement iron candor we need to buy far OTM strike but there is a restriction on zerodha to buy far OTM strikes.
    Once this custodian account is enabled, Can I still trade or buy equities from my normal account?

    • Karthik Rangappa says:

      1) Yup, factored in is the most easiest explanation 🙂 I cant speak of all events, but after the previous rate hike, this one was clearly factored in, making it a non event
      2) the Easiest way is to compare current ATM strikes IV with historical volatility to get a sense of where the volatility is
      3) YOu get the sell leg first? Also you can shrink the strikes, no need to stick to far OTMs right?

  172. Mohit K says:

    Thanks Karthik.

    On 1).
    How do we know if the
    a) Price is already factored in for an event or change?
    b) Volatility is already factored in? Was it because the change in volatility was way more than expected in this case? How much more or less determines the “factored in” part?

    • Karthik Rangappa says:

      1) General market observation and price behavior will reveal this
      2) Yes, again you can observe and calculate this.

  173. Mohit K says:

    Thanks Karthik. Really appreciate your response.

    Any example that you can provide for, How do I know if volatility is already factored in for a stock/index?

    Also, a slightly unrelated question, any twitter handle who dissects market movement that happened that day for educational purposes? For example, why market went today etc or what were the reasons of the rally today etc?

    • Karthik Rangappa says:

      Mohit, you can pick any stock due for corporate action and track this. If the stock has rallied or tanked before the event, then the news is getting factored in already. For example, if say a stock is tanking before the quarterly result and the result is positive, then it implies that the market expected a better quaterly result, hence it tanked. So watch out for things like these.

      About Twitter handle, I’m not sure 🙂

  174. Rohit says:

    Sir I have doubt , is Friday a good day for execute the long straddle in nifty weekly? And if yes then think if i made a straddle on Friday what if the large move come on the Thursday ( expiry day) would that effect my break even point or it will give me the same profit as it gives any other day like Monday, Tuesday, Wednesday

    • Karthik Rangappa says:

      Its hard to conclude that one particular day is best for executing a particular strategy. It really depends on your market conditions. But yes, if you write on Friday, you do get a maximum premium.
