Prop firm rules

Consistency Rule

A prop-firm rule that can limit how much of total profit may come from a single trading day.

What does Consistency Rule mean?

A consistency rule is designed to prevent an account's result from depending too heavily on one unusually profitable day. The exact formula differs by provider and can apply during an evaluation, a funded stage, a payout request, or more than one of those stages.

Why it matters

  • A trader can reach a nominal profit target and still fail a consistency requirement.
  • One very large winning day can increase the additional profit needed before a payout or evaluation requirement is satisfied.
  • The percentage and calculation method vary significantly between firms.

How it works

  1. 01

    A common structure compares the largest profitable day with total accumulated profit.

  2. 02

    For a 50% rule, the best day generally must not represent more than half of the qualifying profit.

  3. 03

    Some firms recalculate consistency only for payout eligibility while others apply it earlier.

Example

If total qualifying profit is $2,000 and the best day contributed $1,200, that day represents 60% of the total. Under a 50% consistency rule, more qualifying profit may be required before the ratio falls to 50% or less.

Common misunderstandings

  • Consistency does not mean every day must produce the same profit.
  • The same provider can use different percentages for evaluation and funded stages.
  • The firm's exact calculation should be checked rather than inferred from the percentage alone.
