FTMO has a Consistency rule applicable to all phases of the 1-Step FTMO Challenge and FTMO Instant Account product. The 2-Step FTMO Challenge has no Consistency rule.
The purpose of the rule is to ensure that no single trading day may account for too large a share of your total profit. This prevents one outsized day from carrying the whole result.
