NSE:BANKNIFTY seems to be in a range and there is lot of resistance on the UPSIDE from Sell Zone b/w 33450 - 33600 levels. If BNF manages to cross this with good volumes on BNF Futures contract then, next resistance can be seen at 33800 levels. On Downside, Upward trendline would act as good Support, if it breaks with volumes then next Downside target would be todays low around 32650 levels followed by 32400 which is a Big Buy zone.
