    "trace": "423afec425004bd8a5e02e1ba5f9b2b0",
    "data": {
        "codes": "BTCUSDT",
        "klineTypes": "1"
    }
}

Drop every interval for that symbol:

{
    "code": 11002,
    "trace": "423afec425004bd8a5e02e1ba5f9b2b0",
    "data": {
        "codes": "BTCUSDT"
    }
}

Parameter	Type	Required	Description	Example
code	Integer	Yes	Unsubscribe protocol 11002	11002
trace	String	Yes	Trace id	423afec425004bd8a5e02e1ba5f9b2b0
data	JSON	No	Scope. Empty clears every kline symbol on this connection
