See, the best timings for Equity Intraday Trading, are when the markets open. It is very volatile, rates keep fluctuating at a very high speed. So if your analysis is correct, you can go ahead and trade during market opening (immediately when the market opens and after market opening). Word of caution though, it is very risky to trade during market opening.
Actually, if you are trading NIFTY (Index), it is good during market opening, but equity is risky, you will have to check the individual scrip (company) i.e their fundamental and technical analysis. Only if you are 100% sure of the trend/movement of the scrip/equity, then only go ahead and trade by taking the advantage of market opening.
One indicator of NIFTY opening in the morning, is in line with SGX NIFTY, check out SGX NIFTY rate on TV before the market opening, when I say market, it is NIFTY. Our NIFTY will open exactly close to SGX NIFTY. So, this indicator also you can use, while market opening.
Secondly, in the afternoon (around 1:30 PM IST), markets move as per the opening of European Markets (like DAX, CAC and FTSE). If European markets open positive then, NIFTY will go up and vice versa. See, this is a general indicator, just for your support.
Equity/Scrip will not move as per what I have said above, only NIFTY will move.
P.S. The above things that I have said is based purely on my personal experience and is all my view. You need to exercise caution while you trade, or rather have your own taste and feel of the market. Please and please do not trade as per what I have said above, it is only my perspective/view.
Hope this helps,
