Exchange API Throughput

Exchange API throughput refers to the capacity of an exchange's interface to handle a specific number of requests per second from a single user or firm. When a trading system exceeds this limit, the exchange may rate-limit or drop incoming orders, causing significant operational disruptions.

For high-frequency strategies, API throughput is a critical bottleneck that must be managed. Traders use rate-limiting algorithms to ensure their traffic stays within the exchange's defined parameters while still maintaining execution speed.

This involves optimizing order batching and minimizing unnecessary requests. In times of extreme market volatility, exchanges often see surges in traffic, making throughput management even more challenging.

Firms that can efficiently manage their API footprint are more resilient and capable of executing strategies during market stress. It is a fundamental aspect of connectivity and operational stability in the derivatives space.
