Order Execution Sequencing

Mechanism

Order execution sequencing refers to the systematic arrangement and prioritization of trade commands within a matching engine or decentralized protocol. It ensures that incoming limit and market orders are processed according to predefined deterministic rules rather than arbitrary selection. By establishing a rigid timestamp or block-based hierarchy, exchanges mitigate front-running risks and maintain equitable access for all market participants. This process remains fundamental to preserving the integrity of order books in high-velocity cryptocurrency and derivatives environments.
