The consistency rule is the rule traders understand the least and breach the most. Unlike drawdown, it doesn't punish losses — it punishes wins that are too concentrated. This post explains exactly how it works and how to trade within it.
What a consistency rule actually measures
A consistency rule caps the share of your total profit that can come from your single best day — commonly "no day above 30–50% of total profit." If your cap is 40% and you make $4,000 total, no single day can contribute more than $1,600. Make $2,000 in one day and you're offside until your total grows enough to bring that day back under 40%.
Firms use it to ensure a funded trader is genuinely consistent, not someone who got lucky once. It's a quality filter, not a loss rule.
How to stay compliant
The habit is simple: after a big day, keep trading at normal or reduced size so more days accumulate and dilute that day's share. Don't rush to the profit target in one session — spread it. If you're close to your cap, a few small green days fix it faster than one more big day.
Whether a firm has a consistency rule at all, and what the threshold is, varies — see the live rules table in Prop Firm Rules Explained and each firm's full review.
FAQ
Does the consistency rule apply to the funded account or just the evaluation?
It varies by firm — some apply it only during the evaluation, others to payouts on the funded account too. Always check the specific firm review before your first withdrawal.
How do I calculate my consistency percentage?
Divide your best single day's profit by your total profit. If the result is above the firm's cap (often 30–50%), you need more trading days at smaller size to bring it down.
