bank nifty is in parallel channel, wait till the market comes @ sopport area(lower parallel line) the you can go long, with good R2R ratio, stoploss would be plased below the support line.
But don't SHORT the market @ Resistance line(upper parallel line) because market is in uptrend, so try to cath the Dips
