Hi. As the title states, I've successfully connected to the server via websocket, but I'm getting no data back. Symbol is 'NQH23_FUT_CME' I haven't subscribed to paid CME live data but I'm assuming that I should still be getting back delayed data. If I'm wrong about this, please let me know. request login json: {"Type": 1, "ProtocolVersion": 8, "HeartbeatIntervalInSeconds": 30, "ClientName": "Client"} subscription json: {"Type": 101, "RequestAction": 1, "SymbolID": symbol_id, "Symbol": 'NQH23_FUT_CME', "MarketDataTransmissionInterval": 0} (symbol_id = int(hashlib.sha1(symbol.encode('utf-8')).hexdigest(), 16) % 4294967295) messages I am getting: 1/ {"Type":2,"ProtocolVersion":8,"Result":1,"Integer_1":0,"MarketDepthUpdatesBestBidAndAsk":0,"TradingIsSupported":1,"OCOOrdersSupported":1,"OrderCancelReplaceSupported":1, "SecurityDefinitionsSupported":1,"HistoricalPriceDataSupported":0,"ResubscribeWhenMarketDataFeedAvailable":0,"MarketDepthIsSupported":1,"OneHistoricalPriceDataRequestPerConnection":0, "BracketOrdersSupported":1,"UsesMultiplePositionsPerSymbolAndTradeAccount":0,"MarketDataSupported":1,"ResultText":"Connected to SC DTC Protocol server.
