## Full-Duplex Communication

Full-duplex communication allows for the simultaneous transmission and reception of data between two points. Unlike half-duplex systems, where only one side can talk at a time, full-duplex ensures that both the exchange and the trader can send and receive information without waiting.

This is critical for high-performance trading where the exchange sends real-time order book updates while the trader simultaneously sends order execution commands. This bidirectional flow is supported by protocols like WebSockets, which are standard in modern web-based trading interfaces.

It minimizes the time spent waiting for transmission turns, thereby reducing overall latency. By enabling continuous data exchange, full-duplex systems support more complex and responsive trading strategies.

It is an essential technical requirement for any platform aiming to provide professional-grade trading services.
