A consistency rule caps how much of your total profit any single trading day may carry - commonly 30-40% - before the firm approves a payout. Breaching it is not a violation: nothing is deducted, you simply keep trading until your best day's share falls below the threshold.

Worked example: FTMO's 2-Step caps your best day at 30% of total profit before a reward (per FTMO's own pages, checked 28 October 2026). Make $10,000 with $4,000 on one day and no payout - make another $4,000 spread across other days and the share drops to 28.6%, unlocking it. Topstep's evaluation variant caps the best day below 55% of the profit target instead (checked 28 October 2026).

The rule exists because firms fund consistency, not luck: a single lucky session is not an edge they can scale. It hurts burst traders most - if your month arrives in two sessions, this gate, not the drawdown, is what stands between you and money. Firms often drop the rule once you are funded (FTMO Futures does).

The full rule, per-firm thresholds and workarounds: the consistency rule; a softer cousin: minimum trading days.

Frequently Asked Questions

Why is a 50% drawdown harder to recover than a 10% one?

A 50% drawdown requires a 100% gain to recover, while a 10% drawdown only needs 11.1%. Recovery math is exponential. At 30% drawdown you need 42.9% to break even. This is why prop firms cap drawdown at 10-12% rather than higher percentages.

What is the 3-5-7 rule in forex?

The 3-5-7 rule suggests risking 1-3% per trade, keeping total open risk at 5% or less, and limiting single market exposure to 7%. It is a general risk guideline, not a prop firm rule, but following it naturally keeps you within most max drawdown limits.

What is a good maximum drawdown?

For prop firm trading, keeping your actual drawdown under 5% is excellent. Most firms allow 10-12%, but staying well below the limit demonstrates strong risk management and gives you a buffer for unexpected market events.

Is maximum drawdown calculated on balance or equity?

It depends on the firm and drawdown type. Static drawdown is typically calculated on starting balance. Trailing drawdown follows your highest equity. Some firms include floating losses in their calculation, making equity the relevant measure.

What happens when you breach maximum drawdown?

Breaching maximum drawdown results in immediate and permanent account closure. All positions are closed automatically, the challenge is terminated, and there is no refund or appeal. It is the final rule with no second chances.

What is the difference between daily drawdown and maximum drawdown?

Daily drawdown resets every day and limits your loss within a single session. Maximum drawdown is cumulative across the entire challenge or funded period. You can breach max drawdown through many small daily losses that accumulate over time.
