If you look at 30 min chart of Bank nifty for today session it was clear from start of the day that buyers are going take the session look at first 30 min candle a pure "bullish wick reversal pattern" it confirmed that options buyers will take over the day!!
Already discussed on 31st Jan analysis keep eye on opening for confirmation of trade. "Check" 45400 ce was trading at 200 at 10 am at 10.15 am it closed at 556 a net 323 points candle it makes your day!
lets look for tomorrow might be same action as today as bank nifty was trading in range in later sessions. But also failed to break resistance twice May take jump from last support at 45600. Still bullish side are bit stronger.
Gap down opening can change the view from bullish to bearish.
