Order Flow Finality

Definition

Order flow finality designates the immutable state at which a transaction request is definitively integrated into a distributed ledger or cleared through a derivative matching engine. This concept dictates the precise temporal point where a trade ceases to be subject to reversion, chain reorganization, or counterparty default risk. In the context of cryptocurrency and financial derivatives, achieving this threshold ensures that the underlying asset ownership transfers irreversibly, establishing a clear separation between pending intent and settled execution.
