I have GMR Nov futures and I want to rollover to December as today is expiry. I want to square off Nov futures and then buy December futures. But the issue is that GRM is in ban period, I trade online and if I square off my Nov futures I won’t be allowed to take a fresh position in Dec futures unless the contract is removed from Ban.
You should call zerodha for this, they will set up permissions for your Client ID to open new position in Dec future, since you are closing Nov future. They will give instruction also, how to do it.
Since you are closing Nov and opening Dec, the overall OI remains same, and hence there is no violation of ban also. So they will help you to do this. Just call them.
