I don't understand how you calculate brokerage

 i understand maximum 20 rs means 20 rs buy and 20 rs  sell 

 total 40 rs brokerage. so  more than 40 rs brokerage not possible in

 1 execute order.

but my cipla delivery order show me 104.25 rs   brokerage.

how you calculate? please explain in detail. i am confuse.

Please check in your contract note, how many trades have been executed and what charges has been applied.

For equity, 0.1% is what max it can be charged on your turnover.

Something is not correct as per your snapshot. Check the actual contract notes to see how much brokerage has been charged.

The trade book is available by means of link Trade Analysis in your old back office, you can use that to get exact trade book details.
