There are two things to this
-
Looks like margin required to trade F&O is going to go up slightly more again.

I just updated my answer to this post
There was a very old rule from SEBI which allowed brokers to either collect MTM losses the same day or the next day. Most brokers to manage risk would do it on the same day and square off positions which didn’t have enough money before market close. We recently had an arbitration order which went against us for doing so, and the client took refuge in this old rule from SEBI that said we could have waited till next day. It is practically impossible to run a broking business if we let clients hold positions overnight without sufficient margins (after the MTM losses). SEBI has now fixed this bit by saying losses have to be collected the same day.
