A protocol providing full-duplex (two-way) communication channels over a single TCP connection. Unlike HTTP/REST, WebSockets allow continuous, real-time data flow between client and server. In Forex, WebSocket APIs are used by some platforms or data providers to stream live tick data or updates. For example, a trading bot could open a WebSocket to receive price ticks without repeatedly polling. This enables low-latency updates (the server can push new data immediately). Both developers and traders leverage WebSockets for real-time needs: developers code bots to consume these streams, giving traders faster and more efficient data feeds.
