If I sell an option can I buy it back or (square off) the position after just 15 min or 30 mins and still receive the premium
Yes u can do that
That is known as intraday trading
U can very well do it
still receive the premium
U wont have the premium with u as soon as u sq off
Then after a day or something will I still have the premium
Sorry for asking i am still a novice for options selling
I ask this because I believe the exchange is in favour of buying the contract yet imposes restrictions on selling
