1. Nifty Bank is only Bullish for one sided direction is above 37700 (Thick Blue line). You can buy ATM/ITM CE to grab fast 100-200 or more points.
2. Nifty Bank is only Bearish for one sided direction is below 36800 (Thick Red line). You can buy ATM/ITM PE to catch 200-300 or more points.
3. My view is that market will be volatile with ups and downs between the range of 37000-37500, let the market cross this range and then look for the opportunity to trade.
