    "4ETH_USDT":{

• data 说明

{
       "4BTC_USDT":{ // 合约符号
           "min_up":"2964.4562", // 开多最小价格
           "max_up":"4090.9496", // 开多最大价格
           "min_down":"3814.2670", // 开空最小价格
           "max_down":"4940.7603", // 开空最大价格
           "market_up":"4090.9496", // 市价开多最大价格
           "market_down":"3814.2670" // 市价开空最小价格
       }
   }

之后每当下单价格限制有更新时，client 会收到数据，例子

{
    "4BTC_USDT":{
        "min_up":"2964.4562",
        "max_up":"4090.9496",
        "min_down":"3814.2670",
        "max_down":"4940.7603",
        "market_up":"4090.9496",
        "market_down":"3814.2670"
    },
    "4ETH_USDT":{
        "min_up":"110.3038",
        "max_up":"155.1606",
        "min_down":"138.9828",
        "max_down":"183.8396",
        "market_up":"155.1606",
        "market_down":"138.9828"
    }
}
