At a glance
The short version
FTUK runs one evaluation program for forex and CFD traders. The headline one, Flex Challenge, asks for a 4% profit target with a 6% intraday trailing max loss and a 5% daily loss limit. This page puts every FTUK 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 FTUK challenge on real historical data before you pay for one.

What the FTUK 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).
A break-even trader passes Flex Challenge 54.2% of the time — that is luck alone, and it is the number to beat.
| Program | Break-even trader | Small edge | Solid edge |
|---|---|---|---|
| Flex Challenge | 54.2% | 70% | 85.1% |
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 FTUK attempt
On Flex Challenge the target (4%) is no larger than the loss allowance (6%). 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 trails intraday, including open profit: a trade that runs 6% 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 a 5% daily loss limit. With only 6% in total, two bad days are the whole account.
A 20% consistency rule applies: your best day can be at most 20% of total profit. One outsized winner can leave you above the target and still not passed.
In simulation, a trader with a small edge (45% wins at 1:1.5, 1% risk) fails 30% of phase-one attempts on the max loss; the ones who pass take a median of 5 trading days.
Rehearse the FTUK challenge on a real chart
The button opens CRTLAB with prop firm mode running on FTUK's Flex 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 FTUK 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 FTUK's rules before the fee is spent.
FTUK fine print worth knowing
Flex Challenge: Pay after you pass (activation fee after target). No min or max days; consistency 20% as listed. Promos can lower target to 2%. FTUK's rules page.

CRTLAB is free to try. You get prop firm mode with FTUK's rules and every other firm's, with every tool the product has, for your first 10,000 candles of replay — roughly two hours of stepping through a chart, no card needed.
