If banknifty open flat then
Banknifty buy above 31300 for target 31350,31400,31430-450 now at 31480 good resistance so if cross and sustain then 31550 then trail SL and extend the target 30 30 point
Banknifty sell below 31180 but small risk so small quantity for target 31120-110,31060,31000-30980 then trail SL and extend the target 30 30 point if banknifty sustain below 30980 then possible to gap fill 30850-770
