It's a falling wedge pattern (BULLISHNESS)
IF 2 move sustain the support line and 3rd wave breakout the resistance level then buy above the resistance level.
As per my view I think nifty might touch 12020 resistance and might break the resistance line.
SBIN might touch the down trendline again and that is the buying point can also buy at around 185-190 price but with small qty and if it touch the line buy more qty and avg it. For mid and long term it can go 240-50-60-70-80!! (RECOVERY IN NOV) this is only a view point.
As of now banknifty have filled the gaps of 19 oct and if it break the first support my view is it should once touch the trendline and market may go down as bc of US election so trade safe till 3 NOV.
