The USD INR Pair (Part 1)

View chapters →

4.1 – The contract

We make an extremely critical assumption at this stage – we will assume you are familiar with how Future and Options contracts work.

Technical Analysis plays an important role in setting up short term currency trades, so we’ll assume you know Technical Analysis as well.

If you are not familiar with these topics, then I’d strongly suggest you read through these modules before proceeding further. The currency and commodities market is largely a Futures market; hence a working knowledge of these derivative instruments is the key.

Now, assuming you understand these concepts fairly well, let us begin by slicing and dicing the USD INR futures contract. The contract specification of the USD INR futures gives us insights on trade logistics.

Here are the salient features of the USD INR pair –

Particular Details Remark
Lot Size $1,000 Inequity derivatives, the lot is number of shares, but here it’s a dollar amount
Underlying The rate of Indian Rupee against 1 USD
Tick Size 0.25 Paise or in Rupee terms INR 0.0025
Trading Hours Monday to Friday between 9:00 AM to 5:00 PM
Expiry Cycle Upto 12 month contracts Note, equity derivatives have an expiry upto 3 months.
Last trading day Contracts trade till 12:30 PM, 2 days before the last working day. Equity derivatives continue to trade till 3:30 PM of the expiry day.
Final Settlement day Last working day of the month
Margin SPAN + Exposure Usually, SAPN is about 1.5%, and exposure is around 1%. Hence roughly about 2.5% is the overall margin requirement.
Settlement Price RBI Reference rate on the day of Final settlement The closing price of spot

To give you a sense of how this works, let’s take an example –

Image 1_USDINR

This is the 15-minute chart of the USD INR pair, as you can see the encircled candle has formed a bearish Marubuzo. One can initiate a short trade based on this, keeping the high of the Marubuzo as the stoploss.

Note that I’m not trying to justify a trade here, my objective is to showcase how the USD INR contract works.

The trade details are as below –

Date: 1st July 2016

Position – Short

Entry – 67.6900

SL – 67.7500

Number of lots to short – 10

1 lot of USD INR = $ 1000

The contract value of 1 lot of USD INR = Lot size * price

=1000 * 67.7000


The margin required for this can be fetched from Zerodha’s margin calculator; here is the snapshot of the same.

Image 2_margins

As you can see, the margin required to initiate a fresh position in USD INR is about Rs.1,524/-. Therefore on a contract size of 67700, this works out to –


= 2.251%

Out of this, I’m guessing about 1.5% would be SAPN margin requirement (read as the minimum margin required as per exchange) and the rest as exposure margin.

Further, the idea is to short 10 lots, hence total margin required is –

10 * 1525

= 15,250/-

A point to note here – when trading equity futures, one has to earmark anywhere between 15% and 65% of the contract value as margins, this obviously varies from stock to stock. In contrast to equities, the margin charged in currencies is way lower. This should give you a sense of how leveraged currency trading really is.

On the other hand, currency sticks to a tight trading range compared to equities—hence higher leverage.

4.2 – The contract logistics

Notice how the currency futures are quoted – they go upto the 4th decimal digit. There is a reason for this – when it comes to currency futures, a number as small as this – 0.0025 is considered big.

When RBI states the reference rate, they quote upto the 4th decimal. Even a minor difference at the 4th decimal can alter the foreign reserves by a large degree. In fact, it is a norm world over to quote the currency to 4th decimal – in case of USD INR, this is 0.0025. This is called the tick size or in currency parlance, a ‘pip’. A pip/tick is the minimum number of points by which a currency can move.

So when the USD INR moved from 67.9000 to 67.9025, it is said that the currency has moved up by a pip.

How much money would you make per pip in the USD INR pair? Well, this should be easy to figure out –

Lot Size * pip (tick size)

= 1000 * 0.0025

= 2.5

This means to say, for every pip or every tick movement you make Rs.2.5/-.

Going back to the short trade, here is how the Marubuzo panned out –

Image 3_Short exit

After initiating the short, the currency pair declined 67.6000. If I choose to close this position, he is how much I would make –

Entry = 67.6900

CMP = 67.6000

Total number of points = 67.6900 – 67.6000 = 0.0900

Position – Short

This could be a bit tricky, do pay attention. A pip as you know is the minimum number of points the currency can move. To know how many pips a currency had moved when it moved by 0.09 paise, we divide the total number of points moved by the pip size.

Number of pips = 0.0900/0.0025

= 36

As you can see the trade managed to capture 36 pips, let us now calculate how much money one would make –

Lot size * number of lots * number of pips * tick size

We know, Number of pips * tick size is as good as the total number of points caught with this trade. Therefore we can restate the above formula –

Lot Size * Number of lots * total number of points

= 1000 * 10 * 0.0900

= 900

Remember this is an intraday trade. What if you were to carry this forward to expiry? Well, we can carry this forward as long as we maintain the adequate margin requirements. The July contract will stay in series 2 days before the last working day of the month.

Here is the calendar –

Image 4_expiry

So 29th July happens to be the last working day of the month. Hence 27th July will be the expiry of this series. In fact, you can hold the contract only till 12:30 PM on 27th July.

Of course, you can always look at the contract to see the exact date of the expiry.

Another question at this stage – at what price will the settlement happen?

The settlement will happen at the RBI reference rate set for 27th July, and it is important to note that the P&L will be settled in INR.

So for example, if I hold this position till 12:30 PM on 27th July and let it expiry, assume the price is 67.4000, then I’d stand to make –

= 1000 * 0.29 * 10


And this money will be credited to my trading account on 28th July 2016. Needless to say, as long as you hold the contract, your position will be marked to market (M2M). This is similar to the way it works for equity futures.

Hopefully, this example should give you a sense of how the logistics for the currency futures work.

Let us quickly run through the USDINR options contract.


4.3 – USD INR options contract

Let us have a look at how the USDINR option contract is structured. You may be interested to know that the option contract is made available only for the USD INR pair. Hopefully, in the future, we could see option contracts on other currency pairs as well. While most of the parameters are similar to the futures contract, there are few features specific to option contracts.

Option expiry style – European

Premium – Quoted in INR

Contract cycle – While the future contracts are available for 12 months forward, the options contracts are available just 3 months forward. This is similar to equity derivatives. So, since we are in July, contracts are available for July, August, and September.

Strikes available – 12 In the Money, 12 Out of the Money, and 1 Near the money option. So this is roughly 25 strikes available for you to pick and choose from. Of course, more options are added based on how the market behaves. Strikes are available at every 0.25 paisa intervals.

Settlement – Settled in INR based on the settlement price (RBI reference rate on expiry date).

Let’s have a look at the USD INR option contract and figure out the logistics. Have a look at the following image –

Image 5_options

From the option quote, we know the following –

Option type – Call option

Strike – 67.0000

Spot price (see RBI reference rate) 67.1848

Expiry Date – 27th July 2016

Position – Long

Premium – 0.7400 (quoted in INR)

We know the lot size is $1000, although the lot size has not been mentioned in the quote above.  Usually, this information is made available in the quote for equity derivatives. So if you are seeing this for the first time, be aware that the lot size is $1000.

Now, if you were to buy this option, what would be the premium outlay? Well, this is fairly easy to calculate –

Premium to be paid = lot size * premium

= 1000 * 0.7400

= 740

The option contract works similar to the equity derivative contracts. Here is another snapshot I captured –

Image 6_option exit

As you can see, the premium has shot up, and I can choose to close my trade right away. If I did, here is how much I would make –

= 1000 * 0.7750


This translated to a profit of 775 – 740 = 35 per lot.

What if you were to sell/write this option instead? Well, you know that option selling requires you to deposit margins. You can use Zerodha’s F&O Margin calculator to get an estimate on the margin required.

Have a look at the snapshot below; I’ve used the calculator to identify the margin required to write (short) this option –

Image 7_option margins

As you can see, the margin required is Rs.2,390/-.

I hope this chapter has given you a basic sense of how the USD INR contracts are designed. In the next chapter, we will try and discuss some quantitative aspects of the USD INR pair and perhaps look at the contract specification of other currency pairs.

Key takeaways from this chapter

  • The contract specification specs out the logistics of the USD INR derivative.
  • The lot size is fixed to $1,000, but this can be changed by the exchange anytime.
  • Expiry of the USD INR contract is 2 days before the last working day of the month. The contract can be held/traded till 12:30 PM.
  • Margins applicable = SPAN + Exposure, usually the margins add upto 2.25 – 2.5%.
  • Currency pairs are quoted upto the 4th decimal place.
  • A pip is the minimum price moment allowed in a currency.
  • Currency options are European in nature.
  • The premium quoted in currency options is in INR.
  • Strikes are available at every 25 paisa price difference.
  • Margins are blocked when you intend to write currency options.


  1. ShreyaDR says:

    Option writing in currency is similar to option writing in Equity?

    If only 2390/- rupees are required to sell one lot n keeping short position till expiry , isn’t it cheaper instrument that index / stock options?

  2. Chandrasekhar kara says:

    Sir how long time will it take to complete module 9&10 i am eagarly waiting for them. Can you please update it with in 2 months?

  3. Darshan says:

    Shreyadr – I completely agree with you. Infact I try the margin with 10 lots and it comes to Rs. 25,433 only. Premium that will be earned is Rs. 7,800. If this trade moves in our favour than there is return on investment of 30.67%. Is there a catch that we have not discussed in this chapter ?

    • ShreyaDR says:

      can you explain which strike price u traded? what was the futures price then? and when u had taken the position, i mean at start of the month or middle or last week of the month or whatever?

    • Karthik Rangappa says:

      There is no catch 🙂

      Margin requirements for trading currency is lesser, simply because of the restricted movements in currency. A diligent trader can explore great trading opportunities here!

  4. ShreyaDR says:

    e.g. say i am bearish on USDINR (futures 67.6250 at present) and wanted to short 4 lots of 69CE… trading at 0.04, i requires Initial margin Rs: 1,530 + Exposure margin Rs: 4,047 = Total margin ?Rs: 5,577
    but Premium receivable ? is only Rs: 240.
    so is it worth to take this trade? now on 7th July and waiting till expiry by blocking 6k for 4 lots and more if wanted more lots?

    • Karthik Rangappa says:

      I cant really comment on the trade 🙂

      You would receive 240 for a deposit of 5577, which if works in your favor turns out to be around 4.3% over next 15 days. Not bad I’d say from a return perspective !

  5. SARATH says:

    F EURUSD: 1.0925 / 1.0950; USDINR: 68.02 / 68.03 how to calculate EURINR (I MEAN BOTH BID AND ASK)? Please help, I am preparing for Nism Currency Exam… i am confused with these calculations on work book,

  6. Naresh says:

    Dear Karthik , Since the trading is done till 12:30 on 27th July and the settlement is done based on RBI announced rates of 27th July, so at what time does RBI announce the rates for that day Thanks

  7. amit says:

    Is carry trade a better strategy for usdinr?
    Pls explain.

  8. amit says:

    Short usdinr each month and carry this trade for the premium at expiry.
    U will receive some 30 paisa.
    I used to do this, but usdinr suddenly shoot from 66 to 67 during china news.
    I booked loss. But if i would continued to hold my position would be in profit in next month or so.
    Now i think the solution for such movement is sell puts.
    Ur opinion.

  9. someonesceptic says:

    Hi Kathik
    What are these restrictions in the movement of currency prices that you are referring to?

    About the RBI reference rate- It is arrived at, by polling quotes from major forex dealing banks. Does it mean that there is no singular spot rate? That if I am an importer and want to buy USD against INR then two different banks might offer me two different rates?

    • Karthik Rangappa says:

      There are a set of designated banks that can participate in this process. RBI calls them individually and asks them for a two way quote, then RBI averages this and arrives at the rate for the day. This is the official rate that everyone quotes.

      Restrictions is mainly in terms of RBI intervening whenever there is a drastic move in the markets – they either buy or sell dollars to support the currency.

  10. sarath says:

    There are lots of currency pair are in the world and we can check each pair rate online in any forex website , my doubt is these pair are trading in which exchange , same currency pair trading different exchanges in the world?now (11-07-2016 08: 45) i watch forex market section and we can see price movement of forex pairs there . and they are trading which market…
    please help karthik . i’m totally confused..

  11. cyberfun says:

    Please explain about creating a Calendar spread with USDINR. Suppose I want to buy August series and sell September series, how do I do it using Ztrader or Pi ? How much margin will be required ? Will it be counted as one trade and brokerage charged accordingly ? How and when is it squared off ?

  12. John Jayasheelan T says:

    What is Tick size and importance of tick size in currency futures and options.

  22. Sainudheen says:

    What is the normal average Volatility in Currency trading, Can you please give an example USD/INR

  23. arvind says:

    Karthik Sir

    I have 2 questions : for example if i buy 1 lot of (USD-INR Aug 2016) @ 67. 30 on july 28th 9: 15 am . if price falls to 67. 10 by evening ( 3: 45 pm ) . should i sell it at a loss of 20 paisa ( by 5 pm ) or hold it till next day to recover my loss ?
    next day price moves to 67. 50 . should i exit next day with 20 paisa profit or hold it till expiry ?

    • Karthik Rangappa says:

      If you expect the prices to recover then you should hold. Or if you a pure intraday trader and do not like taking on overnight risk, then its prudent to square it off.

      For reasons such as this, you need to pre define your trade with stoploss, target, and timeframe…without this there are bound to be a lot of confusions.

  24. arvind says:


  25. Vishwa says:

    Sir, While trading intraday for CDS, will Profit or Loss be credited the same day.

  26. Vasanth says:

    1) As u mentioned above if the rupee depreciates drastically RBI will intervene and buy the rupee to strengthen the local currency like wise fed also will do the same to strengthen the USD. That means both the parties trying to make the market move in sideways only. If so when will be there intervention if its -0.5/1 percentage..In this kind of scenario pls advice that ta is fully not realiable with ta..its better to blend ta with the levels-pls comment

  27. Vasanth says:

    How can I get the usdinr spot rate charts for technical analysis. I think its not available in pi only future contract charts are available. The rates I can get from RBI site as mentioned but is there any possibility to get the spot data chart in pi for better understanding??

    • Karthik Rangappa says:

      Spot is not traded on exchanges, hence difficult to get the data. However you can download the data from RBI site and try plotting on the excel. Or you could try a site like or

  28. Vasanth says:

    As u mentioned there is negative correlation b/w nifty and usdinr. For eg nifty is giving the buy signal and the USD inr is in somewhat higher level with a major resistance. At this point if I buy nifty/sell usdinr can good a better result. Is it the right way by taking position in keeping view of the other with ta for the short term trades(may be intra or swing).if so what’s the odds of winning as per ur exp.

    • Karthik Rangappa says:

      Negative correlation does not mean a signal to trade is generated :)…but of course you can use this information to build a trading system of sorts, something like a pair trade.

  29. Rakesh.K says:

    Hi Karthik,
    today on 19/9/2016
    RBI ref rate INR/1USD =66.8737
    FUTURES(28/9/2016) USD/INR=67.0600 (FROM MONEY CONTROL)
    now my doubt is , [1]In the above chapter you said ref rate is spot rate.
    [2]If i want to enter into futures contract today , at which price i have to enter AND if i want to square off my position at what price in the above list i have to close position.
    I am totally confused . please give some clarity on this sir.

    • Karthik Rangappa says:

      There are only two important rates here – RBI Ref rate and Futures Rate. RBI Ref rate is not tradable. You can only trade the futures…so this is the only rate that matters while initiating and closing the position.

  30. vijay says:

    HI Karthik
    well currently i don’t have any question but just want to say thanks to you and all Zerodha team you guys are doing great job keep continue.
    and I love Zerodha.

  31. manusharma says:

    Hi, I am a newbie as far as futures are concerned. When I am looking at GBPINR then there are two dates like….
    CDS NORMAL FUTCUR GBPINR 26OCT2016 GBPINR16OCTFUT Why are there two dates 26 OCT and 16OCT?

  32. Joseph says:

    Dear Sir,

    Thanks for the chapter, I want to ask how many decimal places a currency exchange rate can go upto and is there a standard practice banks follow in terms of defining decimal places of an exchange rate?


  33. Anjali says:

    Thanks for this module Sir. Is technical analysis concepts applicable on Currency charts as well?

    • Karthik Rangappa says:

      Certainly, TA is applicable on any asset which has continuous time series data (open, high, low, and close).

  34. sohail says:

    can i use pledged stockholding to write currency options?

  35. saurabh1292 says:

    I have a Zerodha Account. How can I view the USD-INR pair (the underlying ) while trading Options and Futures on Kite.

  36. Rahul Sharma says:

    Hi karthik,
    I want to know has options writing (mis)been blocked for currency in zerodha

    • Karthik Rangappa says:

      You are right, MIS is not allowed for option writing in currency. These options are volatile and lacks liquidity. Besides the regular margins itself is very less.

  37. rohit sharma says:

    Hi karthik,
    I have lot of confusions
    If I have option or future contract then after 11:30 on 29 may, I can not trade (May series)
    Let RBI ref rate on 29 is 64.75
    on 31 ref rate is 65.1
    What would be settlement price?
    Does RBI ref rate changes intraday wise
    On one business channel I noticed they show Rs rate vs dollar. What is importance of that if I trade currency
    Please reply

    • Karthik Rangappa says:

      The reference rate would be 64.75 – basically the reference rate of the day of expiry. Note, ref rate of the expiry is also the settlement rate for the series.

      No, RBI ref rate does not change intraday.

  38. Neha says:

    If I buy call option (ATM)on 26 may and ref rate on 26 may is 64.55
    On 29 may ref rate is 67 and on 31 may ref rate is 62
    I want to know I would be in profits or in loss.
    My profit or loss would be according to which reference rate

    • Karthik Rangappa says:

      It depends on the strike price, but in general, a long call option position profits when the spot price increases.

  39. M Kithan says:

    Hi Zerodha,

    Is there any possibility that Cryptocurrency like Bitcoin or Ethereum would be introduced for Trading on Zerrodha Platform?

  40. Prashant Warrier says:

    Hi Karthik,

    As usual, wonderful wonderful work ………Is there any reason that options have such thin volumes on currency…..Considering the very low premium costs, shouldnt it be an attractive instrument for currency traders….

    • Karthik Rangappa says:

      Thanks, Prashant, you’ve been reading Varsity for a while now, glad you still like the contents 🙂

      It’s just lack of liquidity and nothing else.

  41. Aejaz says:

    If I trade with 1 lot of USDINR currency , and take profit of 1pip. . Then what is the profit in rupees?

    • Karthik Rangappa says:

      Copy pasting this from the above chapter, for your reference –

      Lot Size * pip (tick size)

      = 1000 * 0.0025

      = 2.5

      This means to say, for every pip or every tick movement you make Rs.2.5/-

  42. Darshan says:

    Suppose today I entered the trade “Shorted USDINR Sep 64 PE @ 0.15 with 200 Lots” then the premium I collected is Rs. 30,000. Please answer following questions to clear my doubt
    If on settlement day (27-Sep-2017 @ 12.30 PM) if RBI ref rate is 64.5
    1- Will this contract settle just like any other Equity / index contract i.e. CASH SETTLED ?
    2 – Since this contract settled as OTM, it will expired worthless ?
    3 – If this contract expires worthless than I as an option seller will keep the entire premium i.e. Rs. 30,000 ?


  43. Saify says:

    Hi karthik, pls help me with the query :
    Taking Darshan’s example :
    Suppose today I entered the trade “Shorted USDINR Sep 64 PE @ 0.15 with 200 Lots” then the premium I collected is Rs. 30,000.
    Now on the second day if RBI ref rate is 64.5, can i square off my trade on the second day ? If yes, will i be getting margin – the loss(difference in USD) and also will my margin amount gets unblocked ??
    Could you please elaborate.

    • Karthik Rangappa says:

      Yes, you can close the position next day (or anytime after you’ve initiated the position). The moment you block the position your margins will be unblocked.

  44. Saify says:

    Thanks !
    And what if I am squaring off in loss ?
    How will my profit gets calculated ? The loss incurred – Premium ??
    Pls explain..

    • Karthik Rangappa says:

      In this case you will have to take the loss. No profits. Again, the loss will be the difference between the premium received and paid.

  45. Shailendra Saxena says:

    Dear Sir, as we do our homework in stock markets with EOD data of Open/High/Low/Close and volume, applying diferent indicators to adjudge the trend and important levels, is there any website to provide such historical EOD data for currencies ?

  46. Nandan says:

    Hi Karthik ,

    How much money one needs in his account to short 200 lots of usdinr ?

  47. karthikjayasimha says:


    You are doing a great job by educating everyone in a simple language. My doubt is can we apply option strategies to currencies also?

  48. Daniel says:

    ”Currency sticks to a tight trading range compared to equities.”
    Dear sir, I did not understand this sentence. Please elaborate a little.

    • Karthik Rangappa says:

      It means just that – the range within which the currency operates on any given day is much lesser compared to equities.

  49. vipulkumar patel says:

    pls provide currency future demo videos…..

  50. raja sekhar says:

    If I sell 1 lot on GBP INR in one month of contract in option trading. Can I buy it any day within contact.

  51. Rajesh says:

    Hi Karthik,
    Can you please explain the settlement of ITM Currency Options (Call & Put) if I leave it until expiry?

    Thanks in advance…

  52. Pradnesh Mhaskar says:

    I shorted 1 quantity of USD/INR JUN FUT at a price of 65.7675 hold it overnight and bought it back at the price of 65.7200 on the next trading day. On kite in positions it was showing a profit of 47.50 but when I checked my ledger it is showing credit of 59.99 and in particulars it is showing debtors on 2018-04-13. Please explain me why the credit is more than my profit.?

    Also I saw the contract note, there it was written that position carry forward price of 65.7900(it was the closing price of the scrip) and buying price of 65.7200 also it was calculated as 65.7900 – 65.7200 = 70

    Please explain me why there is difference in the selling price.?

  53. shuvam says:

    d)long call
    According to me and as i understand that for bullish we will go for long call and for bearish we will go for short call.But i am still unsure of the understanding or answer i have.Can you please clear my doubt whether i am right or not…???

    I have a confusion here
    Suppose i have taken usd/inr 10 slots in Normal and its in loss so i keep it in postion for 3 days.. so everyday the loss will dibit from my account or only when i sell it.
    Secondly will i get profit everyday
    {if its profit} or only after selling it.


  55. Ranjith says:

    Hi I want to know if dollar increase then usd/inr will also increase and vice versa is this right
    Also, can a correlation between dxy(dollar) and USd/inr can be done while trading

    • Karthik Rangappa says:

      Yes, with $ going higher, the USD/INR is expected to go higher, which implies Rupee is weakening. You can use the DxY data points as an indicator.

  56. Arjun says:

    I sold a put option contract at premium of 1000*0.01=10.. After few days premium was 1000*0.005=5… Wat premium should I receive 10 or 5 or 15

    • Karthik Rangappa says:

      You will receive the amount at which you have written the option. In this case, it will be Rs.10.

      • Layak says:

        There is a catch here.
        Real example that was happened to my account.
        on day 1: I bought USD INR position @68.99 and it was in loss of 8k since USD was gone down @68.75. I took it to carry forward. 8k debited from my account as daily settlement as loss.
        on Day2: When market open, i had seen USD gone down @68.45 and it was showing loss of 17k because whatever the buying rate on day1 was still same (@68.99). on day2, 17k as loss had been debited from account. now total loss became 25k. this was huge loss and my account value reduced by 25k when I seen on day3.
        Here catch was they had debited 8k again on day2.
        Why this was happened, can someone explain?

        • Karthik Rangappa says:

          Layka, how many lots did you have? The math is like this –

          1) Day 1 – you went long @ 68.99, but EOD the price was 68.75. So you will lose 0.24*1000*number of lots. This gets debited from your trading account.

          2) Day 2 – The reference price for the day is 68.75, but the day closed at 68.45, hence you will lose 0.3*1000*number of lots

          The total loss for the 2 days is 68.99 – 68.45 = 0.54 * 1000 * number of lots you hold.

  57. p.s.perumal says:

    I couldn’t able to understand a profit and loss calculation please help me to understand that
    lot size=1000
    tick size=0.0001
    tick value=lot size*tick size=1000*0.0001=0.1
    entry price=1.1639
    exit price=1.1652
    pip=exit price-entry price=1.1652-1.1639=13
    CONVERTING FROM USD TO INR=pip*(usd to inr)
    is my profit calculation is correct or not if wrong means teach me how to calculate

    • Karthik Rangappa says:

      Perumal, on the EUR USD paid, you make

      Sell Price – Buy Price
      = 1.1639 – 1.1652
      = 0.0013

      Multiply this with lot size

      =0.0013 * 1000

      Since the pair is quoted in USD, this is $1.3, converting this back to INR @ fixed reference rate of 69-

      1.3 * 69

      =89.7. This will be your profit.

      So when you take this position, there are 3 risky elements –
      1) EUR
      2) USD
      3) INR Reference rate to USD.

      • p.s.perumal says:

        still i have one more doubt that is in currency we will say
        if Digit ==5 point=0.00001
        if Digit==4 point =0.0001
        pip=(close position-open position)/point
        take profit=pips*no .of lots
        my friend suggested this way to calculate profit is it right

        • Karthik Rangappa says:

          The number of decimals is restricted to 4. A pip is defined as the minimum movement in a currency pair. For example, if EURUSD moves from 1.1784 to 1.1786, then its said to have moved 2 pips.

          Profit = Number of pips in your favor * 1000 * lots.

  58. Joseph says:

    Dear Sir, my question is on intraday futures, what happens to the existing open position when I buy or sell intraday futures. For example, I have an outstanding long infosys carry forward position and today I short intraday infosys. Will my long position be squared off or there is no link between intraday and carry forward contracts.

  59. Javed says:

    Dear Sir,
    I have 10 lots of USDINR SEP 73 CE. Currently its showing Rs 200 profit. I don’t know should I sold all 10 lots or hold it.
    I want to know, how can I claculate profit/loss at end of SEP? If $ Price is say 73.0275 at september last.
    Please answer?

    Hiii sir good morning ‘ I want to trade in usdinr options , will option value become zero on the expiry date as like nifty options

  61. Manas Pandey says:

    Dear sir,
    I am not able to understand how to calculate my profits for currency on brokerage calculator. Like in buy i entered 72.4400 & in sell i entered 72.4475 but what about quantity ? Do one lot means quantity =1000 ?
    & if it so then it is showing a profit of around 5000. & since i can buy 1 lot for around 1000 or 2000 rupees, would i really profit 5000 from just 3 pips movement ?
    Since 5000 seems to be crazy profit for just 1000 rupees or so, i think i am mistaken somewhere, am i ?

  62. Gaurav says:

    Is there any STT trap for “in the money’ currency options, like it is in case of EQUITY options?

    Hi Karthik, I have a question.

    I have a Zerodha account and I have only NSE & BSE segments enabled. Can I trade USDINR with this or do I need to enable CDS or NFO?

    Please help!

  64. Akshay says:


    I have observed that USD-INR quote on Google search is almost same as USD-INR current month NSE future rate during the 9-5 trading hours. However, beyond 5PM, the rate keeps moving on google and the next morning the NSE future price almost always opens at the price being quoted on google. What is the source of google data? I am assuming it is some other international exchange where the same pair is traded. Which exchange is it and should this information anyway affect our trading stratgey on NSE USDINR futures?


    • Karthik Rangappa says:

      I’m really not sure about their data source (NSE I’m guessing). However, you can check for disclosures on the Google finance page.

    Hi sir
    I want to know what would be last trading day for currency options Friday or Thursday and timing

  66. ROHIT SHARMA says:

    Weekly options

  67. Dhrutika says:

    In Kite, I found below issues while trading in USDINR weekly options (on all platforms Kite Web/Mobile/Android app).
    – Unable to square off open positions from “Positions”. Buy/Sell buttons not working from “Positions” list.
    – Unable to Modify order from Pending Order list. However, Cancel order is working. So I used Cancel and placed fresh order.

    Above issues are only in USDINR Weekly options. Monthly options are working fine.

    Please fix them.

  68. Aashna says:

    I wanted to ask that in the last few lines, you said that profit would be of 35 per lot.
    so I can I calculate that in terms of rupees (with a minimum margin of aprox 2000 required for buying one lot as you stated) ?

  69. John Christopher says:


    Hello, I am looking forward to seeing a detailed documentation on the weekly CDS options.

    Well, i am not able to put USDINR graph pair on Marketwatch. All i can see is future contacts. Is there any reason for that? Any symbol error?

  72. Ram says:

    Hey Karthik,
    I was reading about L&T taking over Mindtree by a hostile Takeover, I was thinking why not a article or so should be added to the First module so we can learn about such actions.

    P.S I think a tool should be added to the comments section so that when we are going through a article again, we can find our comments.

  74. Aniruddhsinh Rathod says:


    As per the specs table the settlement price should be the RBI rate on final working day of month.But in the calculation part you took price of last trading day which 2 days prior to last working day. Which one is correct?


    • Karthik Rangappa says:

      They are two different things 1) Settlement price upon expiry and (2) M2M P&L. For both, we end up using the RBI reference rate.

    Where I can get chart of spot price of usdinr pair as futures chart of usdinr available on kite does not show prices after 5pm.

  76. Mani says:

    Hello sir, I am of the view that RBI can intervene any time to control USDINR unlike NIFTY, is it correct sir?

  77. Mani says:

    which means even if I implement a trading system tested over 10 years of data, due to RBI intervention the probability of making money will decrease, isn’t it sir? Which means I am better off sticking with indices?

    • Karthik Rangappa says:

      Yes, fundamentals do play a role. Also, remember, RBI to looks at the market for arriving at the settlement price. So it is not completely dependent on RBI.

    What is the maximum number of lot that I can trade in usd/inr ?

  80. Abhishek says:

    I wanted to ask that I recently went through the nse website, it is stated that the maximum open positions for an individual client cannot be more than 6% of total open interest or 10 million $ for USDINR, the question I have is that if I wanted to take 6 – 7 month far futures in usdinr, so if the amount goes to more than 10 million, so will I be the 6% oi rule be calculated on the specific contract that I am trading or it refers to 6% of total oi in all expires together?

  81. Abhishekk says:

    Thanks sir, but as per my observation far contracts in USDINR have a bid and ask value of anywhere between 8000 – 10000 lots during any time in forex market hours. Please correct me if I’m wrong.

  82. Abhishek says:

    Yup, you’re right there it is reasonably big around 8 – 9 pips.

    Writing to you after a long time. Hope all’s well. So happy to see Zerodha’s progress.

    I have a basic query. I want to initiate a 1SD strangle in USDINR options for Dec series. Please advise what is the reference figure to look at – Dec futures price? Or “REFERENCE RATE – FBIL *” mentioned above option chain? Or spot rate as per Google? or some other rate?

    Though I understood from the above that settlement price is RBI reference rate on expiry date. But my question is – what is the base price as on this moment?

  87. Shyamal says:

    What happened to an ill-liquid loss making ITM currency option(Selling) position on expiry if it is not square-off before expiry.

    Example: 27th Dec Expiry.
    My writing positions are as below: Capital 25.00 Lac. I am sitting with a profit of 1.00 Lac at today’s close(19.12.2019)
    Your Sensibull analysis says If USDINR closes at 71.5 on 27th Dec, My profit will be around Rs.3.25 Lac. which I am expecting.

    200 – 71 CE / 200 – 71 PE
    200 – 71.50 CE / 200 – 71.5 PE
    200 – 72 CE / 200 – 72 CE
    200 – 72.50 CE / 200 – 72.50 PE
    But what will happen to 200 – 72.5 PE on expiry. At what price it will get settled. And what impact will be there in overall charges if this position are left as it is on expiry. Because this position will become ill-liquid by next week.

  88. Namrata Jain says:

    the last working day of this month is 31st December, that is on Tuesday, so the option will expire on Friday i.e., 27th December?

    Hi Karthik,

    When RBI states the reference rate, expiry will close at which price..?
    ex: If USDINR April future is trading at 77.8(assume spot price at 77.5) on expiry morning at 11.25 am and If RBI announces the price at 77.5 (77.2 spot price)so it will be lose for whoever it is holding where earlier profit.

    Hello Folks,

    I have a very basic query and you can help clarify if my understanding is correct. Whenever I trade currency futures like USDINR and hold it for a day or two and sell it at a best profitable price in the mid of the day, I observe that the profit is calculated as per the day’s closing price and not per the price at which I sold.

    Is that how currency futures work?

    • Karthik Rangappa says:

      No, not true. Your P&L is based on the price at which you buy and sell. That is the only reference price to settle your trade.

  110. DP says:

    Thanks Karthik for you prompt response!

    What I have observed is – though I book profits and close the trade the Currency Contract Notes which are received in email always show the the days closing price which is not the one at which I had closed my trade and net amount receivable dosent show the actual amount/ profits.

    I assume Currency Contracts are similar to Future Contracts – let me know if I am correct.

    • Karthik Rangappa says:

      I’d suggest you speak to the support team once for this. I suspect this could be an expiry trade.

  115. vijay says:


    >> Lot size is fixed to $1,000 but this can be changed by the exchange anytime.

    How does one come to know what is the current lot size fixed by the exchange (if it has been changed by the exchange? I checked the USDINR contract on zerodha and it says the quantity as “1”, which I assume to indicate the lot size (unlike in stock index derivatives)

  116. Keshav says:

    hi why i am not able to view weekly usdinr options and futures? Can you please provide the code for the same, say for next week expiry. And for more clarification, reference rate is now officially not polled by RBI. FBIL is now the designated agency to publish the reference rate which i believe is now used by RBI. FBIL has its own methodology of publishing rates daily from the one hour OTC spot market window 11.30 am-12.30 am and the earlier process of polling via banks has been discontinued. Since the methodology is opaque and not published freely, obviously there are many instances when rates published has greyness in them since lot of money is at stake!!!!

    when I try to access the currency margin file (currencySpan.pdf), it says “file is in owner’s bin”
    i would like to know the MIS and BO/CO margin for currency..

  118. vijay says:


    In the Zerodha margin calculator, there is no option of separately checking the margin for a currency future and a currency option. I only see pairs listed with various experies and margin next to them….

    1. does this mean that the margins are the same for futures and options (shorting an option)?
    2. If answer to 1 is yes, then is there any margin benefit for a covered call (as is the case for nifty covered call)?…and if so, where does one compute that?

  119. vijay says:

    Thanks Karthik..

    Your response on 2 – example and even your margin calculator tool shows this for Nifty/BankNifty….what about currency pairs – have you guys worked a provision for reduced margin for a hedged strategy in currencies?

  120. Vijay says:


    read few comments above – can you please confirm that the trading terminal (Kite) is in sync with the margin calculator and not continuing to charge previous margins?… if it is not, can you please advise by when it will be?

    • Karthik Rangappa says:

      Both are in synch, Vijay. Margins on Kite is always right, margin calculator may at times have few minutes lag.

  121. Vijay says:

    Kite margin is much much higher (approx 3x) of margin calculator…i again rechecked today….can you pls have this thoroughly investigated internally and revert?

    This single clarification will completely alter the strategies and position sizes I use hence awaiting…

  122. vijay says:


    My original question was – where can I see the reduced margin for hedged currency trade? your margin calculator has no provision for showing this for currency pairs

  123. vijay says:


    This window doesnot have an option to attach a screen shot….below is what you get in the currency margin calculator tool…this just gives you an option to enter amount of cash against which it will display how many lots I can buy….but nowhere it there an option to enter a future and a call and check margin for a hedged trade.

    What is the underlying for usdinr options, spot or future? If underlying is spot, where do we get real time chart of usdinr spot?

  125. Sharan says:

    Hi Karthik,
    I have a doubt. Future prices and option premium change when the spot price of the underlying equity changes. But as you mentioned the spot price of the Dollar-rupee pair (reference price) given by RBI Remains constant for an entire given day. Then what is the reason for currency derivatives price changes, mirroring those of live actual FOREX market prices, without actual change in RBI’s reference price?
    Is it the anticipation that the next day’s RBI’s New Reference Price will represent the price closest to that prevailing in the FOREX markets for the $-₹ pair at the time of its issue by RBI ?


    • Karthik Rangappa says:

      That is right plus the local demand and supply factor acts as a catalyst for movement in futures price.

  126. Padma says:

    Karthik Sir,

    The knowledge you are sharing here is amazing for beginners like us.

    in general what is the average number of lots a retailer can execute successfully on a USDINR futures , assuming that the target price met. I understand it is case to case basis, but just wanted to understand based on the past data. This is to plan how much i can invest on trading USDINR. is 500 lots a reasonable number for the orders to go through.

    Thank you for your response , in advance.


  127. Padma says:

    Ok Sir, will wait for confirmation. Please provide your thoughts on below also

    1) for scalping on USDINR futures, which exchange is more liquid. NSE or BSE?
    2) on zerodha calculator observed that charges collected by BSE is way far too less compared to NSE. please let me know if I noticed it right
    3) what is the approx. maximum number of lots I can use per trade in NSE so that the trade goes through without much waiting assuming the target price is hit.
    4) what is the approx. maximum number of lots I can use per trade in BSE so that the trade goes through without much waiting assuming the target price is hit.

    • Karthik Rangappa says:

      Max is 10K USD per order.

      1) NSE
      2) Yes, BSE charges are lower

    when can we expect the following
    Currency option chain and
    Nifty weekly options details in Zerodha Marging Calculator

    Are you all working on this front.

    • Karthik Rangappa says:

      This is on the list of things. Hopefully soon. Btw, you can now see the margin in the order placement window itself.

  130. Shyamal says:

    Thank you.
    But if I want to place a multi legged order say Long Put Calendar & Long Call Calendar, is there any place where I can see my Capital requirement for all the 4 legs in place.
    If I place the order through Sensibull option chain than the capital requirement that I see in the Summery (on analyzing the basket order) is not correct.
    For example just now, I was seeing basket order:
    Sell – Nifty11000 put -6th August expiry – 1 lot
    Buy – Nifty11000 put – 27th August Expiry – 1 lot
    Capital requirement was showing as Rs.14.20K which is not correct.
    May I have your comment on this.

  131. Shyamal says:

    This was in the Sensibull Option chain Analyzing Summery. After selecting the legs.

  132. Shyamal says:

    Is there any way we can we can put the screen shot of these Analysis Pages here in this blog. That will give you correct picture of what we see when we analyse the multi legs baskets in Sensibull Option Chain.

  133. Shyamal says:

    Thank you.
    But in Zerodha Margin Calculator, Margin requirement for weekly expiry can not be calculated. Only Monthly expiry can be.

  134. Shyamal says:

    Ok. Thank you.

  135. Shyamal says:

    There is something wrong in 60 day Challenge Profit update.

    For example One of my 60 day Challenge for currency has started on 24th July. Till 7th August my actual profit is 24.06 K, however in 60 day challenge, its showing as 11.06 K.

    Sir, Can i trade forex on any time of the day? Or the time of trade is fixed

  137. Venugopal says:

    In the table it ia mentioned that settlement price is the RBI reference rate on the final settlement day i.e last working day.

    But in the example the settlement price is mentioned as RBI reference rate on 27th july instead of 29th july as said in table.

    Please confirm

  138. Lino says:

    Hi karthik,I’m a big fan
    Could you please tell me if the forex and commodity market is also included in the new leverage rules?

  141. Bharath kumar says:

    Thank you very much karthik. Varsity is the foundation for me to enter into stock market, i cannot describe my thanks to you and zerodha team in words. You guys are the best.

  142. Bikash Naskar says:

    I have a demart account of zerodha. Can i trade the currency & how it’s possible ?

  143. Gowtham h Sankar says:

    Is the maximum risk being limited to span margin or could it incur higher losses , is currency trading price movements regulated ?

  144. Dhruvil says:

    Rbi reference rate is price for settlement but price of Rbi will be as per 12.30 pm or 5 pm for expiry?

  145. Jay says:

    The Indian market closes at 5 pm, and the USA market begins much later after that.

    Suppose something unexpected happens in the USA market against your position and hits your stop loss, what do you do?

    You will have to wait till next day 9 am (Indian time) to exit.By this time your position would have got worse, how to handle this problem?


  146. Jay says:

    You are correct that the stop loss won’t get triggered. This is actually the problem.

    In cases like NIFTY index, stocks etc. you can get out during the market hours when your stop loss is hit. This is because market hours and trading hours are the same.

    This is not the case with currencies, after the Indian trading hour closes at 5:30 PM the rest of the world continues to trade. FOREX is 24/7

    For example

    Buy USD INR at 74.0000 at 4:30 PM on Tuesday
    Stop loss .1000, thus get out price is 73.9000

    Due to some panic in the USA markets, USDINR becomes 73.4000. This will reflect in the Indian markets next day (Wednesday). When I sell I will be selling at 73.4000 instead of 73.9000.

    If USDINR futures in India was 24/7 I could have sold at 73.9000 before it reaches 73.4000. Unfortunately that is not the case .Now I end up with a bigger loss by selling on Wednesday.

    I hope you understand my problem. I want the stop loss to get triggered. Leaving the position overnight might result in a bigger loss than that I was prepared to take.

    The only solution I can think of is to do only intraday trades, and avoid positional trades.

    What do you think?

    • Karthik Rangappa says:

      Jay, but how will that even work when the markets are closed? There is no way that the order can go through. This is how it works in the commodities market as well. At best you can keep your overnight positions hedged and remove the hedge at market open.

  147. Jay says:

    In commodity markets like the MCX, trading hours ( 9 am to 11:30 pm approx.) are similar to the market hours. So you do have opportunities to exit.

    In USD INR the trading hours (in India) are (9 am to 5pm) whereas the market hours are say (from 7 am to midnight, maybe more as forex is 24/7). This means that you cannot exit once the trading hours are closed (at 5pm). The period from 5pm to midnight is when the USA markets open, this makes overnight USDINR positions riskier than commodities.

    I agree with you the order can’t go through, but things would be better the USDINR trading hours would match the market hours (say from 7 am to midnight). That way the overnight risk is reduced, and it would be similar to commodities.

    In the current scenario, hedging is probably the only way out.

    • Karthik Rangappa says:

      True. If you remember the April Crude episode, our markets were closed, but Crude continued to slide. But anyway this is a dead end situation unless exchanges keep the segment open.

  148. Jay says:

    Apart from hedging or doing only intraday, do you there are other solutions?

  149. Pradeep says:

    Hello Karthik,

    Thanks for providing these good information for free..

    However i need some information on the below trade executed in the zerodha platform.

    This trade was taken on 24th Nov.

    I had sold the 20Nov 74 CE USD INR Pair 5 lots and it has made 387 rs loss, i am not able to the close the position now it says 1628 Security has matured, and also it has hit the lower circuit,

    could you please guide me on the next steps.

  150. Sunil Kumar says:

    What is the intraday square off timing for currency trading like USDINR? I mean equity market closes at 03:30, can I continue my USDINR intraday trade even after 03:30?

  151. Roshil says:

    i cant find USDINR indices in kite. where we can find the underlying value price?

  152. Prem says:

    Can u plz explain about how to calculate capital?Based on which I can decide no.of lots for trading.

  153. Rahulsinh says:

    Is the currency segment is included in the new leverage rules? or there will be the same leverage as Zerodha is used to give?

  154. Dhawal says:

    My question is with regard to settlement in Option Trading :

    USD INR Futures Price 73.83 (31-03-21——10:22 AM)
    Expiry – 31-03-2021
    Strike Price 73.5 PE
    Assuming at 12:30 it expires at 73.75 and option goes worthless
    Assuming At 1:30 RBI Ref Rate comes out to be 73.25 based on spot rates .

    So will I get profit 1000 * 0.25 = 250

  155. Amey Palsule says:

    Very Good and simple explanation. Thank You.

  156. R P HANS says:

    One question
    Lot size is $1000 then one pip or ,0025 shall be = 1000*.0025. And also * $ to ₹ conversation ie

    1000*.0025.72= 175/-
    Why conversation of $ to inr is not considered.

  157. Ruben says:

    Today (5/7/21) at 12:30 PM at the time of Weekly Expiry, USDINR May FUT price was trading 73.88 and USDINR 73.75 PE option premium was 0.0225..
    My question is if at the time of expiry PE/CE strike price is on OTM then it expires worthless and premium become zero.. In this case strike price was on OTM but premium was not zero..

    Why it happened?

  158. Ruben says:

    Thanx 4 ur rply..
    I have another one question, on April 29th I have sell 74.25 PE USDINR option whose expiry was on 30th April. I have taken it on the basis of May FUT becoz on 28th April ‘April FUT’ expired.
    At the expiry time at 12:30 PM, May FUT traded at 74.52 but 74.25 PE option premium was .2100..
    Why huge premium being the strike price was on OTM??
    Am I right by choosing the strike price on the basis of May FUT?

  159. Ruben says:

    Why huge time value? I have taken the trade on 29th April of weekly expiry. One day before the expiry.. Which expired on 30th of April..

  160. Embrose says:

    I placed AMO BUY Order for USDINR In Normal ,CNC but It was made sell Order in market price,why it happened ? And In zerodha there is option to place AMO ORDER FOR USDINR or Not, Please reply

  161. Goutham says:

    How does the option pricing premiums are calculated for USD INR contracts. Does Black & Scholes calculator helps here sir.

    • Karthik Rangappa says:

      There is a variation of B&S called the Black 76 pricing model which is used here. The only difference is that instead of spot price, futures price is considered as the underlying.

  162. Vishwak says:


    May I know as to why the margin requirements in Currency Options Selling is so much lesser than say index/stock options? Is there any specific reason for this? Also are currency options strike price dervied from the futures price?

  163. Shiva says:
