@Hope is life In such case you and me can't do anything as big players have lakhs of quantity and the way they can manage side.
Live GMP is just to decide where it can be maximum potential to open.
Ex. Just before listing someone posted yatharth GMP 77 now opened at only 6.1 premium on the day so nothing can he do who posted.
If someone can't bear that GMP is now decreasing after allotment then not read comment here in forum or any source. Positivity is the only key of hoping good until 9:45 but face the reality at same time.
