Banknifty was bullish today, unlike yesterday. It finished as a true bulling engulfing pattern with higher high, lower low and much higher close with strong green body. The high made today (30699) is higher than highs made during last few trading sessions. So now it is near high made on 23rd September, 30801 and hence selling pressure will also be there. So as shown on 15 min chart, sell between 30750-30800 and buy at buying area shown which was created when BNF staged smart rally this morning. All the best. Happy trading.
