Event streaming

When you subscribe to a stream, the WebSocket server will push updates to you when an event occurs on the stream you subscribed to.

Each such message contains class=data and the stream name (stream).

Sample event message:

{
	"class": "data",
	"stream": "BPX/USDT@ticker",
	"pair": "BPX/USDT",
	"price": "0.0123",
	"change": 10,
	"previous": "0.0122"
}
