Execution Requirement

An execution requirement is a constraint placed on a trade to ensure it matches the trader's strategic needs. Examples include immediate execution (like fill-or-kill), total fulfillment (like all-or-none), or specific pricing (like limit).

These requirements prevent unwanted behaviors, such as fragmented trades or bad price fills. By clearly defining these requirements, traders ensure that their trading systems and strategies function as intended.

It is the primary layer of control for any professional participant. Understanding how to articulate these needs through order types is fundamental to successful, reproducible trading results.
