Prop firm challenges are not usually failed by bad strategies. They are failed by position sizing that was never tested against the rule — and by weekend gaps, which are the one risk a challenge cannot be reacted to. This page converts the rules into pips and lots, using verified FTMO objectives and five years of real gap data.
Read from FTMO's own trading objectives page on 17 August 2026. FTMO is used as the worked example because its rules are clearly published; most firms follow one of these two shapes.
| Objective | 1-Step | 2-Step Phase 1 | 2-Step Phase 2 |
|---|---|---|---|
| Profit target | 10% | 10% | 5% |
| Max daily loss | 3% | 5% | 5% |
| Max overall loss | 10% (trailing, end of day) | 10% (static) | 10% (static) |
| Minimum trading days | — | 4 | 4 |
| Best-day rule | Yes — one day ≤ 50% of total profit | — | — |
The best-day rule on the 1-Step deserves attention too. It bars a single day from producing more than half your total profit — which means one enormous winning day does not pass the challenge, it merely makes passing harder. Consistency is a rule, not a virtue.
Percentages are abstract. Here is the same rule set on a $100,000 account, converted into position sizes, using $10 per pip for one standard EURUSD lot.
| Limit | Dollars | Pips at 1 lot | Pips at 3 lots | Pips at 5 lots |
|---|---|---|---|---|
| 3% daily (1-Step) | $3,000 | 300 | 100 | 60 |
| 5% daily (2-Step) | $5,000 | 500 | 167 | 100 |
| 10% overall | $10,000 | 1,000 | 333 | 200 |
Read the right-hand column carefully. At five standard lots, a 60-pip adverse move ends a 1-Step challenge in a single day. On EURUSD that is an ordinary morning. Traders who size for the profit target rather than the loss limit are the ones who fail in week one, and they usually conclude their strategy was wrong when their sizing was.
The arithmetic worth internalising: a 10% profit target with a 5% daily loss limit means you need roughly a 2:1 relationship between your total gain and your worst single day, minimum — and in practice far more, because you will have losing days on the way.
This is the risk that a challenge gives you no way to manage, and the one most rehearsal never covers, because most backtesting skips straight over the weekend as if nothing happened.
Measured across 1,911,141 EURUSD one-minute bars from 3 January 2021 to 30 April 2026 — 309 weekend gaps observed:
| Gap size | Value | Cost at 3 lots | % of a $100k account |
|---|---|---|---|
| Median | 5.4 pips | $162 | 0.16% |
| 75th percentile | 13.6 pips | $408 | 0.41% |
| 90th percentile | 35.0 pips | $1,050 | 1.05% |
| 99th percentile | 127.5 pips | $3,825 | 3.83% |
| Largest observed | 163.5 pips | $4,905 | 4.91% |
Take that last row seriously. Holding three standard lots over a weekend that gaps like the worst one in five years costs 4.91% of a $100,000 account instantly — essentially the entire 5% daily loss limit, gone before you can act, with no stop able to protect you because there is no price in between.
And this is not a freak scenario: 31.39% of weekend gaps exceeded 10 pips, and one in ten exceeded 35. The tail is fat enough that "it probably won't happen" is a poor basis for a funded account.
You can practise the exact rule set before paying an evaluation fee, and doing so is the cheapest possible way to discover that your sizing is wrong.
FXAbsolute lets you rehearse all of this free, with no account — set the starting balance, replay real one-minute data across 28,412,683 bars and 15 instruments, and let the automatic journal show you whether you actually respected your own limits. Discovering you cannot in a simulator costs nothing; discovering it in an evaluation costs the fee.
Rather than quote figures for firms whose pages could not be verified in this pass — prop firm rules change frequently and a stale table is worse than none — here are the rule shapes to compare, and which suits which trader.
| Rule feature | Suits you if… | Hurts you if… |
|---|---|---|
| Static max drawdown | You expect to give back profit at times | — |
| Trailing max drawdown | You rarely retrace after gains | Your equity curve is volatile |
| Lower daily loss (3%) | You size small and trade often | You hold wide stops |
| Best-day rule | Your results are consistent | Your profit is concentrated in a few trades |
| Minimum trading days | You trade regularly anyway | You wait weeks for one setup |
| No time limit | You are patient and selective | — |
| Weekend holding allowed | You swing trade | See the gap table above |
Check the current rules on the firm's own site before paying, and check them again on the day you start — these terms change more often than any other numbers in trading. Anything quoted in a review, including this page, should be treated as a starting point rather than a fact.
As published on 17 August 2026: the 1-Step challenge requires a 10% profit target with a 3% maximum daily loss and a 10% trailing maximum loss measured at end of day, plus a best-day rule limiting any single day to 50% of total positive-day profit. The 2-Step requires 10% profit in Phase 1 and 5% in Phase 2, both with a 5% maximum daily loss, a 10% static maximum loss, and at least 4 trading days.
On a $100,000 account it is $5,000. Trading one standard EURUSD lot at $10 per pip, that is 500 pips. At three lots it is 167 pips, and at five lots just 100 pips. Most challenge failures come from sizing against the profit target rather than against this limit.
Many firms permit it, but the risk is significant and unmanageable once the market closes. Across 1,911,141 EURUSD one-minute bars from 2021 to 2026 there were 309 weekend gaps: the 99th percentile was 127.5 pips and the largest was 163.5 pips. At three standard lots that largest gap equals 4.91% of a $100,000 account, instantly, with no stop able to protect you.
Set a simulator to the exact challenge balance, write down your daily and overall loss limits in both dollars and pips, then backtest while genuinely stopping when you hit them. FXAbsolute allows this free with no account, replaying real one-minute data across 15 instruments, and its automatic journal shows whether you actually respected your limits.
A trailing maximum loss rises as your balance rises, so the floor follows your equity upward. This means giving back profit can breach a limit that a static drawdown would not. FTMO applies it on the 1-Step at end of day. Traders with volatile equity curves generally find static drawdown rules far easier to satisfy.
Position sizing that was never tested against the daily loss limit, trading through a limit in practice because there was no consequence, weekend gap exposure, and treating one large winning day as progress when consistency rules penalise it. All four are rehearsable in a simulator before paying an evaluation fee.
