Bad trading doesn't end
most evaluations.
Rules do.

One realistic trader. Eight real prop-firm rule sets, verified 2026-07. The same seeded Monte Carlo engine that powers our free simulator. Scroll — and watch which rule actually ends the account.

01 · The trader

Meet the trader who should pass.

Modestly profitable, disciplined, consistent — the profile every firm says it wants. Every number in this tour is this same trader. Only the rules change.

Positive expectancy, sane size. Under a plain 10% static floor this profile passes ~91% of evaluations.

the trader's edge, unconstrained — path illustrative; probabilities measured
static floor — this pullback survives trailing floor — follows every high path ends — trailing floor hit

02 · The floor that follows you

A floor that rises with every high.

Apex's drawdown floor trails your best intraday mark. The pullback a static account absorbs becomes, here, the end of the evaluation. Swap only the drawdown mechanism — hold every other rule constant — and the price of trailing appears:

0.0%pass — static floor
0.0%pass — real Apex rule
0.0 ptsthe mechanism alone

MyFundedFutures' end-of-day variant costs 14.1 pts the same way (81.3% → 67.2%). Full method in the study.

trailing floor — never reached −2% daily loss limit day over — the floor never mattered
topstep combine · trail EOD 4% + daily 2% + consistency 50% · mechanism illustrated; pass rates measured
03 · The rule that binds first

Sometimes the famous rule isn't the killer.

Run the same swap at Topstep — replace its trailing floor with a static one — and the pass rate moves by zero. The 2% daily limit and the 50% consistency check end or block the path before the floor is ever touched.

0.0%pass — real rule
0.0%pass — static swap

The drawdown label on the marketing page doesn't tell you which rule will actually end your evaluation. Rule sets interact.

04 · The size cliff

Under tight rules, size is the whole game.

Scale one input — risk per trade — and watch the archetypes separate. The static account degrades gracefully. The tight-rule accounts fall off a cliff: Topstep collapses from 69.6% to 6.0%.

Halving risk from 1.0% to 0.5% buys +44.7 pts at Topstep and only +9.2 at FTMO. Risk size and rule set are one joint decision, not two.

Rules interact.
Simulate the full set.

No single rule killed this trader — combinations did, and the binding rule changed from firm to firm. These odds are measured, seeded and reproducible. Yours are one free run away: your stats, the full rule set, in your browser, nothing uploaded.
