This is not true, you are deducting brokerage from the dmat. You are taking brokerage from profit as well as wallet balance.
On 17th October I had a profit of 1100.25, for one lot of BankNifty.
Buy Price - 237
Sell Price - 310.35
(310.35-237) x 15 = 1100.25

Charges:
Brokerage - 36
Security Transaction Charge - 3
Exchange Transaction Charge - 4.15
Sebi TurnOver Fees - 0.01
SGST - 3.61
CGST - 3.61
Total Charges = 36+3+4.15+0.01+3.61+3.61=50.38

Amount Credited to Account = Profit - Total Charges = 1100.25-50.38=1049.87

So does that mean you are taking brokerage from profit and wallet as well?

Total charges including brokerage

Hello Team,
I have opened an account and taken a Tradepoint subscription as well. I got 15299 wallet points, I don't know how I can use these points. Whenever i trade some points get debited, where do these debited points go? Kindly provide some details.

Profit should be in red color and Loss should be in red color.

Loss is shown in red color but profit is basically shown in faint blue color. Think on it.
