Update - 22 March 2019
I was expecting a sideways rally, but we got a bearish day. I am still bullish. First the fall was not swift and second we had frequent bounce.
I did have to manage some positions. I have taken a bearish straddle in Bank Nifty -3 X 30400CE & -2 X 29000PE.
I have also taken a neutral straddle in Nifty -2 X 11700CE & -2 X 11300PE.
Here are the overall positions:
