Clarification regarding brokerage rate

In Zerodha brokerage charges list, the charges for equity options are Rs 20 per executed order. Is it per order or per lot? If I place 200 Nifty option in a single order, then will I be charges Rs. 20 or Rs. 80.

Also, if order gets executed in 2 trades, i.e., 150 qty in one trade and 50 in another then charges will be Rs. 20 or Rs. 40?

Brokerage charges are per order not per lot.

Rs. 20

A single order can execute in multiple trades, but it’s still one order, so the brokerage will be Rs. 20 only.
