How to Calculate FII Index Option Net buy/sell value

#1

Hi Friends,

I am trying to understand the below data found at
Question: How to calculcate the net buy/sell? Also is it possible to calulcate the net profit
by combining all option writer? Does max-pain gives value 10/20K Crores(2Billion dollars) is real value?
Please point me to correct threads to understand this.

For example for the below data net position is
FII Data on 31st May 2019
Derivative Segment:
Index Futures: -404.59 Crs
Index Options: 2693.02 Crs ====> How this value is reached? Is it true that FII baught options
worth 2692Cr or its notional value? Or the actual value of option baught would be 2692/(12000 nifty strike) = in Lakhs only?
Stock Futures: 2430.99 Crs
Stock Options: 51.23 Crs
