Banknifty is looking bullish. On daily chart, in last session, it finished as a base-like green candle with almost same high as last session but higher low despite Nifty finishing as LH & LL candle. Option chain doesn't show much resistance at 30500, next logical level. The total CALL OI at 30500 is 2nd highest and call writing is very weak. The highest total Call OI and fresh Call writing is at 31000. As for support, on PUT side, highest total OI and fresh Put writing is at 30,000. This means if BNF scales 30500 and closes above it then till around 30680, there is no resistance. However I could not find any clear cut buying levels, so if it drops till 30000, which is unlikely, one may buy there for current expiry.
All the best. Happy trading.
