Non-Sequential Execution

Execution

Non-sequential execution in financial markets, particularly within cryptocurrency derivatives, describes a process where order fulfillment does not adhere to strict time priority; instead, it prioritizes factors like price-time priority or internal matching engine logic. This contrasts with traditional sequential execution where orders are filled in the order they are received, and it can introduce complexities in latency arbitrage and market impact assessment. The implementation of non-sequential execution is often driven by exchange design choices aimed at optimizing liquidity and order flow, impacting trading strategies reliant on precise timing. Consequently, understanding its nuances is crucial for accurate backtesting and risk management in high-frequency trading environments.
