Trailing drawdown, explained: the rule that ends most evaluations

Drawdown rules cause an estimated 60–70% of all challenge failures, and about two-thirds of failures happen in the first 10 trading days. The word "drawdown" hides at least four different machines:

Static: the floor is fixed at the starting balance minus the maximum loss. The most forgiving shape (FTMO 2-Step, FundedNext, The5ers).
End-of-day trailing: the floor rises with your highest closing balance (Topstep, Earn2Trade, MyFundedFutures evaluations). Intraday spikes don't move it; closed profits do.
Intraday trailing: the floor follows your highest open equity, tick by tick (Apex; the funded stages at MyFundedFutures and Take Profit Trader). A strong morning raises your floor into your afternoon.
Dynamic: the floor trails your gains directly (E8 One's 4%) — room you believe you have may already be spent.

The switch nobody rehearses

At two tracked firms the drawdown changes character when you pass: end-of-day in the evaluation, intraday once funded. The demo you practiced on — and the evaluation itself — trained you for a floor that no longer exists. When you rehearse on a demo (the cheap door), rehearse the funded version of the rule, not the evaluation version.

The geometry, in one line

A 6% target against a 4–5% trailing floor means the account ends after roughly one bad day at full size. Sizing so that a normal losing day costs 0.5% of the account is not caution; it is the only sizing the geometry permits — and it is testable, free, on a demo under the same numbers.

Before you pay, take the whole walkthrough

The verdict gives you the expected cost and the rule that applies to you. The Challenge Odds Kit gives you, program by program, the before-you-buy checklist, the style-versus-rules worksheets, the expected-cost workbook, and the payout-protection playbook: how to never hand a firm the excuse to refuse your payout.
