Looks like they are going too fast to match NSE. NSE charging 5k/1 cr. These limit won’t affect to retail but might affect to Prop desk & FII. Also they have tactically done it only for nearest expiry. So that if someone wants to play 0/1DTE might pay high or if they wants lower charges then they can go for monthly expiry.
Volumes are very dry except nearest expiry. These move can fetch dual benefit.
