The Consistency Rule: Why One Good Day Isn't Enough
What the rule says
No single trading day may account for more than 40% of your total profit (30% on Instant Funding) at the point you pass an evaluation or request a payout. If you're up $1,000 total and $500 of that came from one day, you're exactly at the line.
What it's actually filtering for
The rule exists because a single outlier day — one lucky news spike, one oversized position that happened to work — is a poor predictor of whether a trader can repeat their performance with real capital. Firms that skip this check end up funding traders whose entire track record is one good trade, which is a coin flip, not an edge.
The inverse is also true: a trader who grinds out small, repeatable gains across many days is demonstrating something a single home-run day can't — a process that survives contact with different market conditions.
How to stay comfortably under it
Rather than tracking the percentage manually, the practical fix is behavioral: cap position size so that no single day's realistic best case exceeds roughly a quarter of your profit target. If you're chasing an 8% target on a two-step evaluation, that means no individual day should be designed to capture more than 2% on its own — the rest comes from showing up and repeating the process.
