Throughput Capacity
Throughput Capacity is the maximum number of orders, cancellations, or transactions a trading system can process within a given timeframe without compromising performance. In high-volume markets, this capacity is a vital metric for both exchanges and participants, as it determines the system's ability to handle peak loads.
When throughput is insufficient, the system becomes a bottleneck, leading to increased latency and potential trade failures. Exchanges continuously upgrade their capacity to keep up with the growth of algorithmic and high-frequency trading.
Capacity planning involves rigorous stress testing to simulate extreme market conditions and ensure the system remains stable. It is a fundamental technical constraint that influences the design and scaling of all modern electronic trading platforms.
