Some mistake in calculation, buddy...
If u entered with 2 lots & exited 1 lot in "scalp" trade and the 2nd lot as per the "flow", then you should average your exit price to know the CORRECT figure of your profit.... you have just added profit from scalp trade & profit from flow trade, and the resulting figure appears as if that was the total profit by selling 2 lots at one go....
the correct picture will be exactly half of what u have shown... reason as I just mentioned...
I think seniors will agree to this method of calculating profit....
Total GP = Rs 490 * 100 nifty = Rs. 49000
Assuming brokerage cost to be Rs 250 per trade of 100 nifty (both sides including), such exps. = Rs250 * 13 trades = Rs. 3250
So, Net profit = 49000-3250 = Rs 45750...
verify with your contract notes...
no misunderstandings to be there, bro
