If that is 20700 level, 11L:1L is P:C, it is doubtful bcos there is Calls unwinding in OI 20700, currently at todays LoD and highest call unwinding at that level.
20800 +/-50 appears to remain closing tgt as of now.
Towards 20650-700 can be as its within +/- 100-150, so upside we've seen, now downside is pending
