Bank Nifty Options 12 Dec 2019

As discussed Bank Nifty made a high 31337 which was 2 points from our resistance level. It made a low around our support zone , although last hour volatility pushed bank nifty further to 30996 where it could not stay for 30 min and we saw a sharp reversal towards close. Overall , good day for those who just watch price action to make trading decisions. Hopefully my subcribers were able to make some money out of those key levels.
