Challenge Rules
One-Phase Challenge: The Single-Step Path to Prop Trading Funding
An evaluation with a single trading phase where passing the profit target and staying within risk limits immediately qualifies you for a funded account.

Full Explanation
A one-phase challenge represents the most streamlined evaluation structure in proprietary trading, where you need to complete just a single trading phase to qualify for a funded account. Unlike the more common two-step evaluation process, you don't need to prove yourself twice—hit your profit target while respecting risk limits once, and you're immediately eligible for funding.
The fundamental appeal of one-phase challenges lies in their efficiency. You're essentially cutting your path to funding in half compared to traditional two-step evaluations. Where a standard challenge might require you to first pass a Phase 1 with an 8% profit target, then complete a Phase 2 with a 5% target, a one-phase challenge combines these requirements into a single evaluation period. This means you could potentially be trading a funded account weeks sooner than with multi-phase alternatives.
Typically, one-phase challenges require profit targets ranging from 6% to 10% within 30 to 60 trading days, depending on the prop firm. The daily loss limits usually mirror standard industry practices—commonly 5% of your starting balance—while maximum overall drawdown limits typically range from 8% to 12%. These parameters reflect the accelerated nature of the evaluation: since you only get one shot, the requirements are often slightly more demanding than individual phases in multi-step challenges.
The psychological dynamics of one-phase challenges create both opportunities and pitfalls. On the positive side, you avoid the mental reset that comes with transitioning between phases. Many traders struggle when moving from Phase 1 to Phase 2 because the pressure changes—you're no longer just proving basic competence but demonstrating consistency under funded account conditions. With a one-phase structure, you maintain the same mindset and strategy throughout the entire evaluation.
However, this streamlined approach also means higher stakes for every trading decision. In a two-step challenge, you might recover from a rough start in Phase 1 by taking a more conservative approach in Phase 2. With one-phase challenges, there's no safety net or second chance to recalibrate your approach. Every trade carries the weight of your entire evaluation, which can lead to either more disciplined trading or increased pressure-induced mistakes.
The cost-effectiveness of one-phase challenges varies significantly. While you might pay a similar upfront fee to traditional challenges—typically ranging from $99 to $599 depending on account size—you're essentially getting faster access to potential profits. If you pass, you start earning from your funded account sooner. If you fail, however, you need to purchase a completely new challenge rather than just retaking a single phase.
Risk management becomes particularly crucial in one-phase evaluations because you can't afford to have 'learning days' the way you might in the first phase of a two-step challenge. Your strategy needs to be fully developed from day one. This reality makes one-phase challenges better suited for experienced traders who have already proven their consistency, rather than beginners still refining their approach.
The time pressure in one-phase challenges also influences trading style selection. Scalping strategies, which generate frequent small profits, can work well because you need to accumulate your target within a single evaluation period. Conversely, swing trading approaches that might take weeks to develop become riskier because you have limited time to recover from losing positions.
Many traders underestimate the importance of profit consistency in one-phase challenges. While you might be tempted to take larger risks to hit your target quickly, prop firms still evaluate your trading behavior for funding decisions. Erratic profit curves or excessive risk-taking might technically pass the challenge but could result in closer scrutiny during your funded account trading.
The key to succeeding in one-phase challenges lies in treating them like a condensed version of professional trading rather than a sprint to the finish line. Your daily profit targets should be reasonable—typically 0.2% to 0.5% per day—allowing for natural market fluctuations while maintaining steady progress toward your overall goal.
Worked Examples
Example 1
Scenario:You start a $100,000 one-phase challenge requiring 8% profit ($8,000) within 30 days with a 5% daily loss limit and 10% maximum drawdown
Day 1-15: You generate $4,200 profit through consistent daily gains averaging 0.28%. Day 16: A bad trade causes a $3,800 loss, bringing your balance to $100,400. Since $3,800 is less than your $5,020 daily limit (5% of current balance), you remain in the challenge with $3,600 remaining to reach your target
→You continue trading and eventually reach the $8,000 target on day 24, passing the challenge and qualifying for the funded account without needing a second phase
Example 2
Scenario:You purchase a $50,000 one-phase challenge with a 10% profit target ($5,000) and maximum 8% drawdown ($4,000), planning to trade forex majors over 45 days
Week 1-3: Steady progress brings you to $3,100 profit. Week 4: Market volatility causes a $2,400 loss, dropping your account to $50,700. Your total drawdown from peak ($53,100) is $2,400, well within the $4,000 limit, and you need $1,900 more profit to pass
→You adjust your position sizing, focus on high-probability setups, and reach the $5,000 target in week 6, immediately becoming eligible for funded account status
Example 3
Scenario:You enter a $25,000 one-phase challenge requiring 6% profit ($1,500) within 60 days, but struggle with consistency in your first two weeks, generating only $200 profit
Remaining time: 46 days. Remaining target: $1,300. Required daily average: $28.26. Your account balance: $25,200. Daily loss limit: 5% of balance = $1,260 maximum daily loss
→The lower daily pressure allows you to maintain your systematic approach, and you successfully complete the challenge with $1,580 profit on day 52, avoiding the need for any additional evaluation phases

How This Applies at Prop Firms
Several major prop firms offer one-phase alternatives to their standard evaluations. FTMO provides a one-step option alongside their traditional two-step challenge, maintaining their standard 5% daily loss rule but combining profit targets into a single 10% requirement. The Funded Trader similarly offers streamlined evaluations where traders can bypass their typical two-phase structure by meeting higher initial requirements in one continuous period.
