Prop Firm Challenge Rules Guide —
Design Evaluations That Work

How to set challenge rules that attract serious traders, provide a fair evaluation and protect your firm from excessive payout risk.

The Six Core Challenge Rules

1. Profit Target

The minimum profit the trader must achieve (as a % of starting balance) before the challenge period ends.

  • Phase 1 standard: 8%
  • Phase 2 standard: 5%
  • Single-phase standard: 8–10%
  • Too high (>12%): Traders will perceive as unfair and choose competitors
  • Too low (<5%): Very high pass rate, high payout exposure

2. Daily Loss Limit

The maximum loss allowed in a single calendar day (measured from start-of-day equity or from daily opening balance).

  • Standard: 5% of account balance
  • Relaxed: 6–7% (marketed as "Expert" tier)
  • Strict: 3–4% (for "Conservative" tier)
  • Measurement: From start-of-day equity or from opening day balance (specify clearly in your T&C)

3. Maximum Drawdown

The maximum cumulative decline from the account's peak equity (relative) or from the starting balance (absolute).

  • Standard relative drawdown: 10%
  • Standard absolute drawdown: 8–10%
  • Relative is more firm-protective; absolute is simpler for traders to understand
  • Many firms now offer both variants at different price points

4. Minimum Trading Days

The minimum number of calendar days on which the trader must have placed at least one trade.

  • Standard Phase 1: 5 trading days
  • Standard Phase 2: 3–5 trading days
  • Purpose: Prevents one-day lucky trading from passing the evaluation

5. Maximum Trading Days (Time Limit)

Some firms impose a maximum number of days to complete the challenge phase.

  • Standard: 30 calendar days for Phase 1, 60 days for Phase 2
  • Unlimited: Many modern firms have removed time limits to appear more trader-friendly
  • Consideration: Unlimited time increases infrastructure cost (simulation accounts must remain active)

6. Consistency Rule

Prevents a single unusually large winning day from accounting for the trader's entire profit target.

  • Standard: No single day's profit can exceed 50% of total challenge profit target
  • Strict: No single day's profit can exceed 30% of total profit
  • Example: On a 8% target, the consistency rule means no single day can contribute more than 4% (at 50% rule)

Optional Rules

  • News Trading Restriction — No open positions within 2 minutes before/after major news events (NFP, FOMC, CPI). Prevents volatility exploitation.
  • Weekend Holding Restriction — No positions held over the weekend. Reduces overnight gap risk for the firm's funded accounts.
  • Maximum Position Size — Maximum lot size per trade (e.g. 5% of account in a single position). Prevents all-in Martingale-style trading.
  • Instrument Restriction — Some firms restrict trading to major forex pairs only, excluding exotic pairs with wider spreads that can be gamed.

Challenge Rules FAQs

What is a good profit target for a prop firm challenge?

The industry standard profit target for Phase 1 is 8–10% and Phase 2 is 4–5%. Setting targets above 10% for Phase 1 significantly reduces pass rates and may be seen as predatory by experienced traders. Single-phase challenges typically require 8–10%. Instant funding programmes have no profit target — the fee itself is the firm's protection.

What drawdown limit should a prop firm use?

Max drawdown of 8–12% is the industry standard. 10% is the most common single figure. Using relative drawdown (from peak equity) is more protective for the firm but harder for traders to understand than absolute drawdown (from starting balance). Most top prop firms now offer both versions at different price points.

Should I use daily loss limit or just max drawdown?

Both are recommended. Daily loss limit (typically 5%) protects against a single catastrophic trading day. Max drawdown (10%) protects against gradual account erosion over many days. Using only max drawdown allows a trader to have a very bad single day (e.g. -9.9% in one day) without automatically failing. Using both creates a more robust evaluation.

What is the minimum trading days rule for?

The minimum trading days rule (typically 3–10 days) prevents traders from getting lucky on a single day of high-volatility news trading and passing the challenge without demonstrating real skill. It forces traders to trade across multiple sessions, making the evaluation more meaningful as a predictor of consistent funded account performance.
