Update - 11 December 2019
Previous trades were all fine. But suspecting call writing the previous day, I got out of my 11800 put.
I wrote 11950 CE and 12050 CE spread but I was skeptical of writing bearish spread at bottom so I closed it and wrote a 11900 straddle.
At little lower levels I wrote Bank Nifty calendar which incurred loss but got countered by other trades.
I was looking for sideways movement and suddenly market started jumping so I closed some strangles at profit and loss and wrote bull put spread on Bank Nifty and Nifty.
Here are the open positions:
Here is the detail of the trades:
