Update - 9 September 2019
I was holding my 26300 Put and 28100 Call. Later I squared off 26300 Put and replaced it with 26600 Put.
To test the bottom, I sold 10750 Put and bought 10650. It immediately came in profit.
I created another position. I sold 10800 Put and Bought 10600 Put of 19 Sep 2019. It immediately came in profit so I replaced 10800 Put with 10850 Put.
Market kept making new high so I created some more calendars with 10900 Put sell and 10750 Put buy of 19 Sep 2019.
