Please see news for NSE cuts fees on options, currency derivatives.
When will Zerodha pass on the fee cuts to its customers?
This is meant for trading members/brokers and not clients. For the first 3 crores for the broker (not for one client), there is a saving of Rs 12500 which is across all clients in a month. If a broker has 50,000 clients, it will be Rs 12500 across 50,000 clients, less than Rs 0.5 for a month. The charges after that is Rs 50/lakh itself. The entire first slab is introduced I think to get inactive brokers to start paying money or start trading F&O.
