🔒 PA lock active: the threshold stopped trailing at start + $100.
Intraday engine: the threshold follows your peak equity including open unrealized profit, tick by tick. An open winner that retraces still moved the line up.
Threshold = peak equity − drawdown amount. On the Intraday engine, peak equity updates in real time and includes open unrealized profit. On the EOD engine, the peak is your highest end-of-day balance, so intraday spikes don't move the line — only the close does.
Funded (PA) lock: once the threshold climbs to your starting balance + $100, it stops trailing permanently. From that point you can't trail yourself out of an account — the breach line is frozen.
Breach price: room left ÷ (contracts × point value) = how many points against you before the account dies. Two NQ contracts at $20/pt turn $1,300 of room into 32.5 points. That number should exist in your head — or on your chart — before every entry.
Apex's 4.0 restructure removed the legacy 75K/250K/300K accounts, the MAE rule, and 30% consistency (now 50%, PA only). Trailing drawdown by account: $1,000 (25K), $2,000 (50K), $3,000 (100K), $4,000 (150K). Guides written before March 2026 quote dead numbers — full side-by-side rules for FTMO, Topstep and Apex are on our prop firm rules comparison.
