Order Lifecycle
The order lifecycle represents the complete journey of a trading order from initial creation through final settlement. This process encompasses multiple states, transitions, and interactions between various market participants and systems, forming a critical workflow in financial markets.
Understanding order lifecycle stages
The order lifecycle follows a defined sequence of states and transitions, each representing a specific phase in the order execution process. Understanding these stages is crucial for trade lifecycle management and regulatory compliance.
