move around 15500, +,- last three month its in sideways Is it strong resistance? and what happen next is it brake resistance?
agreed. BNF has been in a range for a long time. Break out likely, but direction is uncertain.
I am biased towards upside.
Even in this range bound market of Bank Nifty you get around 750 points (15500 to 14750) which is good enough for doing some decent trades/profits. In the long term, if breakout happens, I feel it will be up trend.
