What if ITM sell let expire

General
1

If Seller sells Banknifty ITM option at 3:25 suppose 25 rs and market closed near this premium and seller lets it expire. My assumptions are

  1. Buyer will not be able to sell because seller lets it expire
  2. This 25 rs premium will be seller’s profit? (Buyer’s option will be lapsed).

Am i right?

2

if it is closed as ITM buyers option will not lapse. Under new rules if buyer lets it expire he may not get any thing.

3

will seller get this 25 premium

4

Both let expire then who will get profit

5

Short Seller will get Premium. he gets it at the time entry itself.

6

It means if seller sells just ITM at 15:29:58 he will be always in profit.!!!
