Definition
Consistency rule
A cap on how much of total profit may come from a single day (or trade) — exceeding it can block passing or payouts.
Typical form: 'no single day may exceed 30–50% of total profit'. One outsized winner can therefore disqualify a payout even when the target is hit — you must 'balance' the curve with more trading days.
The rule targets lottery-style gambling, but it equally punishes legitimate swing styles whose profits concentrate in few trades. Firms without it suit big-winner strategies better.
