One query related to 'Volume' and 'Change in OI' on NSE option chain for scripts under F&O ban.
As during ban period, one is only allowed to close open position and cannot add new position, Number of contracts traded, i.e. Volume should equal Change in OI. But when I check on option chain for securities like SAIL, IDEA, which are in F&O ban today, it does not seems to be the case. There is difference in volume traded and Change in OI.
Request if someone can help clear my understanding on the same. Thanks.

Nowhere did NSE say your order will be rejected only penal/disciplinary action will be taken for increasing position.
Retail brokers put a layer of security over their clients trades but that's not true for all types of NSE members esp those who have direct access.
so just as an example, i had sold 10 lots a week ago, now i bought 4 today and then sold back 1.
Day open OI = 10 and chg in OI -3 but volume is 5.
so why should they be equal and my net position is also decrease in overall position( OI ) ?
Same math for counter-party, they could have same positions reduced or someone has actually increased OI and will get flagged EoD.
