The risk per trade each challenge actually needs
One per cent is the number everyone reaches for, and it is described everywhere as conservative. Across the 46 challenges whose rules we have read, it works on 2 — where working means a four-in-five chance of reaching the target before a losing streak ends the attempt.
The size each one does need is below, worked out from its own published caps. It runs from 0.1% down to 0.1% .

A 40% win rate taking 2R winners. “Needs” is the largest size at which the chance of a fatal losing streak drops to one in five or below; “trades there” is how many the target then takes. Each programme links to its rules, with the source and the date they were read.
Why the answer is so far below instinct
Because the cap that ends most attempts is the daily one, and it is small. At 1% risk a 3% daily limit is three consecutive losses — and at a 40% win rate, three in a row is not an unusual week, it is a normal one. Over the fifty or so trades a 10% target needs, seeing one somewhere is close to certain.
Halving the risk doubles the losses you can absorb, and the probability of a run twice as long does not halve — it collapses. That asymmetry is the whole reason the useful answer sits where it does, and it is also why the step from 1% to 0.5% buys more than the step from 0.5% to 0.25%.
What it costs is time. Half the size means roughly twice the trades to the same target, so the attempt takes about twice as long. That is the actual trade being made, and it is worth making: the fee is the same either way, and a slow attempt you finish beats a fast one you do not.
What this table assumes
- · One in five is a choice, not a finding. It is roughly where a failure reads as bad luck rather than as arithmetic. Prefer one in ten and every figure here roughly halves.
- · Assumes each trade is independent. Correlated positions — three majors against the dollar — lose together and count as one.
- · Assumes every trade risks the same amount. Raising size after a loss shortens the streak you can survive.
- · Uses your stated win rate. If that came from a demo account or a good month, the figure below is optimistic.
- · It applies each cap at its starting level — pessimistic on a static drawdown, close to right on one that trails at the end of the day, and optimistic on one that trails intraday. The static programmes are shown at their worst; the intraday-trailing ones at better than they are.
On the numbers above
Fidelcrest — Micro Trader — Aggressive
It comes out ahead on the chance a losing streak ends the attempt, at 1% risk per trade, at 19% — 6 percentage points clear of Fidelcrest's Pro Trader — Aggressive, the next best.
This is computed from the published rules, not chosen. Whichever programme wins that calculation appears here, including firms we earn nothing from, and it changes when the rules do. It says nothing about payout reliability, platform, spreads, or whether a firm pays at all.
Questions
- What risk per trade should I use in a prop firm challenge?
- Between 0.1% and 0.1% depending on the programme, not the 1% that is treated everywhere as conservative. At 1% risk, only 2 of 46 gives you a four-in-five chance of reaching the target before a losing streak ends the attempt. The figure is set by the tightest cap that can end the attempt, divided by your risk — so it is a property of the programme, not of your strategy.
- Why is the answer so much lower than 1%?
- Because the daily loss limit, not the overall drawdown, is what ends most attempts, and it is small. At 1% risk a 3% daily limit is three consecutive losses. A 40% win rate produces three in a row often enough that, over the fifty or so trades a 10% target needs, it is close to certain. Halving the risk doubles the losses you can absorb, and the probability of a run twice as long falls away far faster than by half — that is why the useful answer sits well below where instinct puts it.
- What does trading smaller cost me?
- Time, and that is the whole trade. Half the risk means roughly twice the trades to reach the same target, so an attempt that would have taken a month takes two. It is worth making: a slower attempt you finish beats a fast one you do not, and the fee is the same either way.
- Does this mean the challenges are unpassable?
- No. It means they are unpassable at the position size most people bring to them. Every programme here reaches the threshold at some size, and the ones with a wider daily limit reach it while still letting you trade meaningfully. What the table rules out is buying an attempt and trading it the way you trade your own account.
Once you have the figure, the position size calculator turns it into lots for the instrument you trade — which is not $10 a pip on gold or on anything quoted in yen, whatever the round numbers suggest.
