I came across this line eg, for today if nifty closes above 8010 be long, some say 8060, if not then be short? HOW TO FIND THIS POINT?

there is nothing like this thing , if you want to do like this thing then you should watch options data , where significant amount of call writing or put writing has happen , look today example , even after market open gap up , huge call writing is seen . at lower levels stronger hands are buying puts from start of the trade , may be something is left for monday due to fed member comment about rate rise,
