this looks great! I found most trading journal is all abt "in trade" and "after trade". not much abt "before trade". If you are a manual trader, make pre-trade checklist i believe is very import.
I've done similar work like you by create checklist by excel.
Well, sadly, i still can NOT follow my rules, so now im neither using full automatic strategy(multicharts) or semi-auto strategy(computer do the entry ,attach with ninjatrader ATM) or computer do the entry ,tp1, breakeven and trailing stp, im doing all the pnl count and starting ending time..
