Consistency Rule
A consistency rule is a prop firm requirement that limits how concentrated your profits can be. Rather than judging only your total gain, it looks at the shape of how you earned it: typically it caps the share of your overall profit that any single day (or single trade) is allowed to contribute. Clear the total, but earn too much of it on one session, and you can fail or delay a payout despite being net profitable.
The exact threshold varies by firm and changes over time, so treat any specific percentage as something to confirm in your current account's rules rather than a fixed industry number. The principle is what's stable: firms want to see a repeatable process, not a single outlier that a coin flip could have produced.
Why it matters
Consistency rules exist because one huge day is weak evidence of skill. A firm handing out real capital wants traders whose edge shows up repeatedly, not someone who happened to catch one violent move at maximum size. From the trader's side, the rule quietly reshapes behavior: it discourages betting the account on a single setup and rewards spreading gains across sessions.
The practical trap is passing the profit target while failing consistency. If one day carries too large a slice of your total, you can be up plenty and still be offside. That's why a daily profit ceiling is a natural companion — deliberately banking a controlled amount each day, instead of one blowout session, keeps your profit distribution inside the rule.
In MimikTrader
MimikTrader gives you the raw material to watch concentration yourself: the P&L calendar includes a month-consistency view that lays out your daily results side by side, so you can see at a glance whether one day is dominating the month's profit. It's a reporting and journaling view — part of the Pro plan's analytics — not a firm rule MimikTrader imposes. Pair it with a daily profit target if you want to actively flatten the shape of your results.
