Tricky interface of Exchange penalty for inadequate margin and interest charged on cash deficit

[ShubhS9]

Had this case in mind, so better to be cautious.

Bought options on Monday, sold on Tuesday, after which I bought options immediately and got charged a penalty, why?

This happend very recently. It was quite shocking to know that most of the profits I made were wiped off because of some exchange/Sebi policy which is very hard to understand.
