Why do most people fail prop firm challenges?

Not for the reason the advice assumes. At 1% risk per trade — the figure treated everywhere as conservative — a 40% win rate at 2R gives roughly a 78% chance of hitting a losing streak long enough to end an FTMO 2-Step attempt before the target is reached. The trader did nothing wrong on any individual trade. The risk setting and the drawdown cap were simply incompatible, and that was knowable before paying the fee.

What risk per trade should I use in a prop challenge?

Far less than you would trade normally, and the reason is arithmetic rather than caution. Halving risk from 1% to 0.5% roughly doubles the number of consecutive losses you can absorb, and the probability of a run that long falls away much faster than linearly — on FTMO’s 2-Step it drops from about 78% to about 19% at a 40% win rate. It also doubles the trades needed, which is the trade you are making: more time in exchange for surviving the streak.

Does a higher win rate make challenges easier?

It helps twice over: fewer trades to reach the target, and shorter expected losing runs. But it is the input you control least. Risk per trade you set in the order ticket; win rate is a property of a strategy measured over enough trades to mean anything. Adjust the one you can actually change.

Is a 1-step challenge easier than a 2-step?

Usually the opposite, and the pricing implies otherwise. One phase means a lower total profit target, but 1-step programmes generally pair it with a much tighter drawdown — FTMO’s 1-Step allows 3% daily against the 2-Step’s 5%. At 1% risk that is three consecutive losers instead of five, and the probability of three in a row is far higher than five. Fewer phases, less rope.

What is the difficulty ratio?

Total profit target divided by total drawdown allowance. FTMO’s 2-Step is 1.5: you must make half again as much as you are permitted to lose. Alpha Capital’s Alpha Three is 2.67. It is computable from figures every firm publishes and appears on no pricing page, and it is the single most useful number for comparing two programmes.

How to pass a prop firm challenge

Every guide to this says manage your risk and stay disciplined. That advice is not wrong, it is just not actionable — nobody sets out to be undisciplined. The useful version is arithmetic, and it can be done before you pay the fee.

Here is the whole of it. A profit target needs a certain number of trades. Over that many trades, your win rate makes a losing streak of a given length either likely or unlikely — that is not opinion, it is a calculation. The firm's drawdown cap decides how long a streak you survive. Put those together and you get the probability that the attempt ends before the target does.

What that probability actually is

Every programme whose rules we have read, ranked by the chance that a losing streak ends the attempt first. Move the sliders to your own numbers.

The number that surprises people

One per cent risk per trade is the figure everyone treats as conservative. At a 40% win rate taking 2R winners, it gives roughly a 78% chance of hitting a fatal streak on FTMO's 2-Step before reaching the target — and about 97% on their 1-Step, where the daily cap is tighter.

Those traders did nothing wrong on any individual trade. They took a normal position size and met a normal losing run. The setting and the rule were incompatible from the moment the fee was paid.

Halving the risk does not halve the danger

It collapses it. Going from 1% to 0.5% doubles the losses you can absorb, and the probability of a run twice as long is much less than half as likely — FTMO's 2-Step falls from about 78% to about 19%.

The cost is time: half the risk means twice the trades to reach the same target. That is the actual trade being made, and it is worth making. A slower attempt you survive beats a fast one you do not.

Fewer phases usually means less rope

A 1-step challenge looks easier because the total profit target is lower, and it is priced as though it were. But firms pair the single phase with a tighter drawdown: FTMO's 1-Step allows 3% daily where the 2-Step allows 5%. At 1% risk that is three consecutive losers instead of five — and three in a row happens far more often than five.

Set the slider above to 1% and sort by the last column. The 1-step programmes cluster at the bottom.

What this model assumes, and where it is wrong

· 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 the drawdown cap at its starting level throughout. On a trailing drawdown that is accurate. On a static one it is pessimistic once you are in profit, because banked gains buy room the model does not credit you with.

The first three push the real figure up and the last pushes it down, so treat the number as the shape of the problem rather than a forecast. The shape is what matters: it is the difference between a setting that can work and one that cannot.

What follows from this

Three moves, in the order they help. Cut risk per trade until the fatal streak is one you would be surprised to see — the table will tell you where that is for your win rate. Then pick the programme, not the price: the difficulty ratio and the daily-limit rule differ far more between firms than the fees do, and a daily limit that pauses the account rather than closing it is worth more than any discount.

Only then think about the fee. And price the attempt rather than the sticker — three goes at $500 is $1,500 unless the firm refunds on passing, which some do. The challenge calculator does that arithmetic, and the published rules are here with the source and date for each.
