Update - 23 July 2019
I had created strangles and ratios yesterday which were very far, so when market fell, they proved to be delta resistant. Theta decay also helped.
Near 29000, I created two separate calendars with -5X29000 PE 25 July, +5X28700 PE 1 Aug and later or -5X29200 PE 25 July, +5X28800 PE 1 Aug 2019. Later I covered it at profit of 31 points collectively. Market fell after that.
At 29200 I also created -5X29300 CE, -5X29300 PE, +5X29500 CE, +5X29100 PE on Bank Nifty which I am still holding. At 29100, I again created -3X29200 CE, +3X29400 CE, -3X29200 PE, +3X29000 PE. Both the strategies are limited loss limited profit with good risk reward and suitable if the market is to expire sideways. I also did the same on Nifty with -3X11350 PE, -3X11350 CE, +3X11300 PE, +3X11400 CE.
Let us see how the trades goes. Here is the screenshot of final positions:
