## Comment on Basics on Options Shorting/Writing

Hi Nithin ,

So is it possible to get a rough premium value of the option for the next day by putting in these values. From the site “http://www.nseindia.com/products/content/equities/indices/historical_pepb.htm”. I am not seeing any volatility%. But when I put the below values in “http://www.option-price.com/implied-volatility.php”. I got the volatilty as 18. I would like to know if i am doing it correct. Pls correct me if I am wrong

Calculate Implied Volatility for 14800 Put Option 28-aug-14

Underlying Price =14700

Exercise Price =14800

Days Until Expiration =19

Interest Rate =8.3

Dividend Yield =1.34

Market Price =265

Implied Volatility = 18 %

Then putting these same values in option calculator I got Below values. So what i guess is the premium for the 14800 Put Option 28-aug-14 would be around 278 Rs?
