Your Brokerage must be for Apr 2022 till date, I guess !
OP's Brok charges are only for a few days - IF I read his trade-diary correctly. He has not mentioned the exact period.
I think - if his brokerage is FREE , then *My Brok charges* which HE refers , must be Taxes and other charges .
Anyways, GST should be only 18% on the Brokerage+STT etc amount, I assume !
Only pretext of future hope on behalf of all small traders, in very near future , MOST of the brokers MAY follow , FREE Brokerage model or at least very cheap Monthly Brokerage Plans !
That day is not far away.
