Order Book Implementations

Architecture

Order book implementations, particularly within cryptocurrency exchanges and derivatives platforms, necessitate a layered architecture to manage high-frequency trading and complex order types. The core components typically include a matching engine responsible for order routing and execution, a persistent data store for order history and market state, and an API layer for external connectivity. Scalability and resilience are paramount, often achieved through distributed systems and redundancy to withstand market volatility and potential denial-of-service attacks. Furthermore, the design must accommodate diverse order types, such as limit orders, market orders, stop-loss orders, and more complex derivatives contracts, while maintaining deterministic execution.
