You can see buy/sell order quantities and observe them together with movement of price post listing.
Generally most big moves(bulk deal or QIB buying) come till 11 am and whole day it moves in a range. You can put stop loss of price lowest between 10 am to 11 am and keep on trailing your profit as much as high it goes.
Usually 2nd day opening of price and next 5-10 minutes price is highest and then profit booking comes. Here you can also get to know any bulk deal happened on listing day.
These are general observation and every listing is different and this concept doesn't work always so book profit as per your expectation with falling into trap of greed or fear.
