I don’t think that’s true. Long term contacts would have a difference. You basically can’t close all of your position until expiry, if you fail to do so now.
I have more than 20 short options I cannot exit all of them .
in case I am continuing , since from tomorrow its only 65 Quantity per lot , so if I have to exit I should have 65*75%5 = 975 quantity then only I can exit right ?
