All support and Resistance are drawn on the chart. Today my prediction is that Banknifty Future may touch the shaded region which I have drawn on the chart. If banknifty future rejects from the shaded region we can buy put with the SL of upper line of the shaded region. You can buy atm or slight ITM put along with selling of 500 points far OTM if you get the above mentioned scenario. Above shaded region, it'll turn bullish.
