Long bank only if 15 min candle closes above 30845.80 for call option buy trade. Use these trendline and fibo levels for scalp intraday trades. The market will be volatile . Best thing to do is use a strangle (Sell call put in a range ) and sell few more lots if premium increases on either side . If scared hedge with buying far OTM call put. This hedge part is used by big fund houses like JP Morgan , Barcklays etc to hedge their billion dollars in trading. Like they do insurance of their billion dollars by paying few crores, :p.
