The numbers your firm grades you on
Your firm doesn’t judge your strategy. It judges your rule-breaks.
A funded account doesn’t die from a bad strategy — it dies from a daily-loss breach on a Tuesday. Prop firms grade you on two numbers, daily loss and max drawdown, and the trades that breach them are rarely your setups: they’re the revenge entry ten minutes after a stop-out, the doubled size after two green days, the position held through news you swore you’d skip.
PnL Book is a trading journal built around that fact. Tag the trades that broke your rules and it totals what each habit costs in your account’s currency. Revenge trading: −$1,840 this month is not a feeling — it’s the exact slice of your drawdown budget that one habit ate, priced in the same dollars your firm measures you in.
