Comparing NSE and INX has its own caveats as NSE reports premium over and INX reports notional turnover.
For example 27 June 2020 index options at NSE
premium turnover is 7200 Cr
Notional turnover is 1046624 Cr
This is only true for options and not for Futures. INX main turnover is in options. So taking absolute turnover for comparison is bit tricky. As options value traded is much lower than notional turnover ( which represents the underlying asset ). This is why I calculated is based on money per contract.
