Update - 13 September 2019
I was expecting a sideways movement so I sold 28400 CE and 26800 Put. But around 27800, I felt bullishness and I exited it.
I then sold 19 Sep 2019 10900 Put and bought 10700 26 Sep Put. I was expecting a rally but not so swift. So I closed 10900 Put and replaced it with 10950 Put of 19 Sep 2019.
Here are my net positions:
