WebSocket API

WebSocket protocol is a new HTML5 protocol, which provides full-duplex communication between web browsers and web servers. Connection can be established after one handshake. Web server can then push business logic data to web browsers.Advantages:

Request header is small in size (around 2 bytes) during communication Since there is no need to create and delete TCP connection repeatedly, it saves resources .

**We strongly recommend developers to use Websocket API to access market related information and trading depth.**

The connection will break automatically when a network problem occurs
