At a glance
The short version
MasterFunders runs 3 evaluation programs for forex and CFD traders. The headline one, Core Challenge, asks for 8% then 5% across 2 phases with a 10% static max loss and a 5% daily loss limit. This page puts every MasterFunders rule set in one table, runs each through thousands of simulated challenges to show what the rules alone do to your odds, and opens a chart that enforces them candle by candle — so you can rehearse the MasterFunders challenge on real historical data before you pay for one.
MasterFunders challenge rules, program by program
Rules as published on masterfunders.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: $3k, $5k, $10k, $25k, $50k, $100k.
What the MasterFunders rules do to your odds
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).
Of MasterFunders's 3 programs, Core Challenge leaves a break-even trader the most room (28.5% pass) and Lite Challenge the least (25.3%).
| Program | Break-even trader | Small edge | Solid edge |
|---|---|---|---|
| Core Challenge | 28.5% | 71% | 93.4% |
| Lite Challenge | 25.3% | 48.3% | 71.4% |
| Speed Challenge | — | — | 1-day limit: not comparable |
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.
The rule most likely to end a MasterFunders attempt
On Core Challenge the target (8%) is no larger than the loss allowance (10%). That is a generous shape — the account can absorb as much as it needs to make — and it is why this program's odds sit close to what your edge alone would predict.
The max loss is static, measured from the starting balance — the most forgiving kind. Profit you bank widens your room rather than dragging the floor up behind you.
There is a 5% daily loss limit. With only 10% in total, two bad days are the whole account.
In simulation, a trader with a small edge (45% wins at 1:1.5, 1% risk) fails 13.7% of phase-one attempts on the max loss; the ones who pass take a median of 16 trading days.
Rehearse the MasterFunders challenge on a real chart
The button opens CRTLAB with prop firm mode running on MasterFunders's Core Challenge 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 MasterFunders 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 static 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 MasterFunders's rules before the fee is spent.
