How to know if relative volatility is higher for the option?

So I was going through Bull Call Spread / Bear Put Spread . Both of these strategies are recommended when the relative volatility is higher so we can cash in maximum premium value.

From nse-india website , I’m able to find the current volatility of the option , but I am not sure if it’s relatively higher than yesterday or so .

Can someone please help me out here ?

Hi Siva,

Thank you for your patience , although I think you must be wondering why I’m not referring Varsity for details like this . But I do refer topics here and there though not completely :slight_smile: .

What I’m having trouble is that I could find the current implied volatility of an option , but I also want to know what was the value yesterday or a week ago .

Thank you again for your patience , and please don’t mind my stupidity :slight_smile:

I have been trying to get this data for months now. There is not a single site including nseindia which provides the historic implied volatility. Everywhere it is only the stocks hostoric actual volatility. The solution I am using is to manually maintain IV of each stock daily from NSE option chain page. My wife does this for me (for all 170 odd fno stocks) by the time I return from office. :slight_smile: Yes she is so sweet;) But I am trying a macro to automatically pull the IV in excel to unburdon her. :slight_smile:

Implied volatility changes every second and is different for every strike of option and it is impossible to capture for all strikes so we can consider IV on daily basis and at individual stock level.
Niftyvix index captures the same for nifty so index is taken care and data is readily available.
Coming to stocks there are data vendors like esignal,optionwin,tickerplant who provide these details for a premium, one can contact them or as mentioned above one can start saving them on daily basis.


Implied Volatility(IV) is basically required to calculate the option price. The value of IV is of less significance historically as the volatility averages out over certain period of time.
I believe, the relative volatility is w.r.t volatility of different option strikes in comparison. So to enter BullCallSpread/BearPutSpread strategy, i think current volatility values of different option strike is enough.
