Banknifty has taken support in the level 20100 - 20150. It will move upside with the targets 20200, 20280, 20320, 20380, 20420. When it breaks 20420 we can add 20480 as our next target. Stoploss is 20080. Always use trailing stop to protect your profit! In yesterday's comment I have shown the support level for banknifty.
