Consistency Rule

Context & Mechanics

What the rule requires

The consistency rule caps how much of total profit may come from a single day. If a prop firm requires 30 % consistency, for example, the best day may account for at most 30 % of cumulative profit. Above that, the rule is breached – usually without ending the account: the trader must raise total profit through further trading days until the ratio is met again ("diluting it out"). Some providers additionally apply the logic to individual trades or to identical position sizes.

Where the rule applies

Depending on the provider, the consistency rule applies in the two-step challenge, in the funded account, only for the first payout – or not at all. It is one of the least standardised prop-firm rules. It is especially common in instant-funding models, where no multi-week evaluation checks consistency. Critically: some providers only check the ratio at the payout request – a breached value then surfaces when the profit split is at stake.

Why the rule exists

Without a consistency requirement, a challenge could be passed with a single leveraged all-or-nothing trade. The rule filters out that lottery behaviour and protects the provider's business model: payouts should go to traders whose results look reproducible. Together with the daily loss limit it disciplines both extremes – oversized losing days and oversized winning days.

Handling it in practice

As an illustrative example: a trader reaching the $8,000 profit target with daily gains of at most $2,000 can never breach a 30 % ratio. Constant position sizes and a daily target below the critical threshold are the simplest protection. The GlanWick simulator evaluates the profit distribution across trading days before a paid challenge starts – GlanWick is a training and simulation tool and not a prop firm itself.

Execution Example

A trader has reached the $8,000 profit target in a challenge on a nominal $100,000 account; the provider requires a 30 % consistency rule (best day ≤ 30 % of total profit).

Check: total profit $8,000, best day +$3,200 → share 40 % → rule breached; the pass is not recognised despite the profit target being reached.
Target maths: $3,200 may be at most 30 % → total profit must rise to at least $3,200 ÷ 0.30 ≈ $10,667.
The trader continues with small, even daily gains; at $10,700 total profit the best day sits at 29.9 % → rule met, challenge passed.
Alternative scenario: with daily gains capped at $2,000 from the start, the ratio would never have exceeded 25 % – no rework needed.

Execution Risk & Errors

Taking note of the provider's consistency rule only at the payout request

Trying to reach the profit target with one single large trade

Not knowing whether the ratio is calculated per day, per trade, or on position sizes

Stopping trading after an outlier day instead of diluting the ratio out

Assuming all providers use the same consistency threshold

Frequently Asked

Does a breached consistency rule end my account?

Usually no. Unlike loss limits, the account is generally not closed; passing or payout is delayed until the ratio is met again through further trading days. Exact consequences vary by provider.

How do I avoid problems with the consistency rule?

Through even daily gains below the critical threshold. Illustrative example: with a 30 % ratio and an $8,000 target, a daily cap of $2,000 keeps the ratio compliant automatically.

Does the consistency rule also apply in the funded account?

It depends on the provider. Some check it only in the challenge, others at every payout, some not at all. Check the conditions before signing up.

Can I analyse my profit distribution in advance?

Yes. The GlanWick simulator evaluates the distribution of daily gains so outlier days become visible before a paid challenge starts.
