Leeloo Trading Challenge Simulator

Rules as published on leelootrading.com, checked 21 October 2026. Prop firms revise rules often — confirm on their site before you buy; the source for each program is in the fine print below. Account sizes offered: $25k, $50k, $100k, $150k, $250k, $300k.

The same trader passes one firm's challenge far more often than another's, and the difference is the rules, not the trader. To isolate it, each program below was run through the CRTLAB challenge simulator for three traders: a break-even one (50% wins at 1:1 — zero edge, so any pass is the rules' slack plus luck), a small edge (45% at 1:1.5) and a solid edge (45% at 1:2).

A break-even trader passes Leeloo Practice Account 33.2% of the time — that is luck alone, and it is the number to beat.

Simulated: $100k account, 1% risk per trade, 2 trades a day, 60 trading days or the program's own limit; multi-phase programs multiply each phase's pass rate. Min-day and consistency rules are not simulated. Run your own numbers in the prop firm challenge calculator.

On Leeloo Practice Account the target (6%) is 1.2× the 5% loss allowance — a middle-of-the-road shape. Neither rule dominates; an average edge at sensible risk passes more often than not.

The max loss trails intraday, including open profit: a trade that runs 5% in your favour and comes back to break-even has used your entire allowance without closing a loss. This is the rule that catches traders who let winners breathe, and it is the first thing to rehearse.

There is no daily loss limit in the evaluation, so the max loss is the only floor — one undisciplined day can use all of it.

You need at least 10 trading days before a phase can pass, so a single big day does not finish it.

In simulation, a trader with a small edge (45% wins at 1:1.5, 1% risk) fails 48.6% of phase-one attempts on the max loss; the ones who pass take a median of 7 trading days.

The button opens CRTLAB with prop firm mode running on Leeloo Practice Account rules. The chart's HUD carries your progress to target, the distance to the max loss and the daily floor, and it calls the verdict — passed, phase two, or breached — the moment a rule is hit, exactly as the firm's dashboard would. Every Leeloo Trading program and account size is one click away in the rules panel, and so are the other 98 firms in the catalogue.

What makes it a rehearsal rather than a demo account: you replay real historical data, candle by candle, on any of 38 markets from 1-minute to weekly, and you can do in an evening what a live challenge takes a month to show you. Run the same week three times with three different risk sizes and watch which one the intraday trailing floor catches.

There is no account to fund and no time limit on practice — the replay waits for you. When your rehearsals pass consistently, you know the edge survives Leeloo Trading's rules before the fee is spent.
