About Apex Trader Funding's rules
Apex Trader Funding is a futures-focused prop firm with a trailing threshold drawdown that locks in profits. The trailing nature significantly raises the effective risk for swing-style equity curves.
Key risk rule
Trailing threshold follows your highest equity peak intraday. Larger accounts have proportionally tighter drawdowns, making them harder to survive.

Why most Apex Trader Funding traders fail
The 5% drawdown ceiling looks generous in isolation. The math says otherwise. At 2% risk per trade, you bust after just 2 consecutive losers. With a 50% win rate, that sequence happens roughly once every 4 trades — and most evaluations require enough activity that you'll see it.
Apex Trader Funding's trailing drawdown makes it worse. Every winning streak permanently raises your floor, so a strategy that nets +5% across volatile swings can fail before reaching the profit target.
The fix is structural, not tactical. Reducing risk per trade from 2% to 1% cuts your expected ruin probability by roughly 75%. Reducing it to 0.5% effectively eliminates rule-based failure for most positive-edge strategies.
