  成功建立和 WebSocket API 的連接之後,向 Server 發送如下格式的數據來訂閱數據:

{
  "sub": "market.$symbol.kline.$period",
  "id": "id generate by client"
}

參數名稱是否必須類型描述默認值取值範圍
symbol true string 交易對 ethbtc, ltcbtc, etcbtc, bchbtc......
period true string K線周期 1min, 5min, 15min, 30min, 60min, 1day, 1mon, 1week, 1year

正確訂閱的例子

正確訂閱

{
  "sub": "market.btcusdt.kline.1min",
  "id": "id1"
}

訂閱成功返回數據的例子

{
  "id": "id1",
  "status": "ok",
  "subbed": "market.btcusdt.kline.1min",
