GLOSSARY · PROP FIRMS
What is consistency rule?
A consistency rule limits how much of a trader's total profit may come from a single day or single trade, intended to filter out results driven by one lucky position.
What it means
A common formulation caps the best day at 20% to 40% of total profit. If your best day exceeds that share, the payout is delayed or reduced until further trading brings the distribution back within the limit.
Why it matters
The intent is reasonable — it distinguishes a repeatable process from one large gamble — but it penalises legitimate strategies with uneven return distributions. Breakout systems in particular make much of their money on a small number of days by design.
What this changes in practice
It is one of the rules most likely to be overlooked when configuring a bot, because it does not fail the account, it silently withholds the payout. Read it before starting rather than at withdrawal time, and check whether it applies to the evaluation, the funded stage, or both.
