Trailing vs static drawdown
Static: your max drawdown is measured from your starting balance. Trailing: it 'follows' your highest balance up, then locks. Trailing is stricter.
Daily loss limit
Most firms also enforce a daily loss limit (often 3–5% of the account) that resets each session. Hit it once = evaluation over.
Why traders fail
They size for the profit target, not for the drawdown. One bad morning takes them out. Sizing for the drawdown first automatically keeps you inside the daily limit too.
