Options/futures data for 27th Jul (EOD)

From options action:

1. 5500 now looking like Himalayas with 1.2Cr Calls vs 16L puts

2. 5400 had confusing action 7.8L 5400CEs covered looked fine but almost 9L puts covered too! Fake move? Profit booking since decay mostly over?

July: 2Cr OI down 22% (58L shares cut from OI)

Aug: 1.5Cr OI up 63% (58L shares cut from OI)
