WebSocket Latency Management
WebSocket latency management involves optimizing the persistent, full-duplex communication channels used for real-time market data streaming and order execution. In crypto markets, where price updates occur in microseconds, the delay between an exchange sending a message and the client receiving it is critical.
Management strategies include optimizing packet serialization, reducing the overhead of data frames, and utilizing high-performance network stacks to minimize processing time. Developers often monitor the time difference between the exchange's timestamp and the local receipt time to calculate drift.
High latency can lead to toxic order flow where a trader is consistently filled at stale prices. By managing this delay, traders improve their competitive edge in order flow execution.
Effective management requires constant monitoring of network conditions and infrastructure tuning to maintain a low-latency environment.
