Smart Order Router Latency

Smart order router latency refers to the time delay incurred by an algorithm while determining the best execution venue and transmitting the trade instructions. In high-frequency trading, even microsecond delays can result in missed opportunities or worse execution prices.

This latency is influenced by network speeds, the computational complexity of the routing logic, and the response times of the connected exchange APIs. As markets become more interconnected, minimizing this delay becomes a primary competitive advantage for institutional traders.

High latency can lead to stale data being used for decision-making, which increases the risk of adverse selection. Engineers focus on optimizing hardware, software architecture, and network topography to reduce this bottleneck.
