The key to understand this is to look at that * and ** at the bottom of the table.

* means notional turnover

1) Notional turnover is calculated as strike price + option premium * lot size
Eg. from you data table using record of 2-Apr-18:
this is (10700 + ATP) * Total contracts traded
so say on that day you bought 1 lot for inr. 12, then,
your notional turnover is : (10700 + 12) * 75 = inr. 9.63L

This is a simple way of calculating what you would actually
inr. 12*75 = inr. 900

Now you can see how bloated the notional TO really appears. That's why NSE has been criticized when Daily F&O values are released
bcos it looks like huge Trx have taken place when they haven't.

Since the criticism, you can read the line in ** wef 2015.....
which means that two values are reported and that is Premium TO using the calculation explained above.
