it will be good if we have everything integrated.
if you want to short list the stock before the market opens then chartink and screener could be good choices.
the developers are selling screener as a seperate product if i am not mistake.
so we have realtime data with broker and screener with trading view (website seperately).
if these two are in same place, we should be able to get realtime signals. forgive me, i have made the above assumption. dont know if fyers is offerring the trading you screener already within the trading window.
