Ok, just looked over the statement again.
Made approx 450 round trip trades over 2 days/nights (delineation is kinda blurry since I traded the overnight session too) - mostly ES and a small number of RTY.
Trade sizes were between 1 and 6 contracts max, mostly 1, 2 or 3, rarely 6...
Would you agree that it's kinda hard to "in your head imagine the fee structure" given the above?
Yes, I would agree that trying to keep track of THAT many trades in the head during a trading day would be quite a challenge.
I am trying to visualize what that would be like in the NT7 environment, and it is difficult for me. I have never pushed around that volume of contracts.
The easiest way to handle that, I guess, is to remember the number 4. Or 5, if you are conservative. That is your cost per RT, all commish inclusive.
So nearing the end of the trading day, you look at your final balance, and look at the number of trades you made in the trade summary screen, and do the maths of number of trades *5 bux, and work it from there.
That what I do in my head every time I take a swing trade in the index futures.
I do not sit there and over-lever on max contracts...Rather, I am constantly calculating in my head what the overnight margin is, times number of contracts, +/- PnL, remembering my NLV from the previous session, and determining if I will survive the terrible, horrible, very scary overnight session.
