This is my very own peronal opinion that it will test the bottom channel and we can c further tumbling. Better to close long positions for now and observe the price to come inside the channel if want to go long on nifty
I think There is still a strong support line near 10928.36 (in Daily chart). It can go further down till 10928.365 then it can bounce back or further down upto 10000 (In Daily Chart). Lets see what will happen. If we draw trendline from 28th sep 2017 Candle to 10928.36 (below today's candle) then we find exact location of strong support.
