    "data_type": 1,
    "data": {
        "pair":"BIX_BTC",
        "update_time":1536648343927,
        "asks":[
            {
                "price":"0.0000683",
                "volume":"1048.8046"
            },
            {
                "price":"0.00006831",
                "volume":"1008.2509"
            },
            ... // other data
        ],
        "bids":[

                "price":"0.00006801",
                "volume":"2.3472"
            },
            {
