I don't know how to fix this error:  "During the algorithm initialization, the following exception has occurred: Unable to locate exchange hours for Future-cmeglobex-BRRV18"  The message doesn't tell me which statement causes it, but I was able to nail that down by commenting out various statements. 

Have I done something wrong with the symbol, or do I just not understand how to properly use this API or what?


public class BasicTemplateAlgorithm : QCAlgorithm
        private Symbol _spy = QuantConnect.Symbol.Create("SPY", SecurityType.Equity, Market.USA);
        private Symbol _bct = QuantConnect.Symbol.Create("BRRV18", SecurityType.Future, Market.Globex);



       public override void Initialize()
            SetStartDate(2018, 1, 07);  //Set Start Date
            SetEndDate(2018, 10, 11);    //Set End Date
            SetCash(100000);             //Set Strategy Cash
            AddEquity("SPY", Resolution.Minute);
            AddFutureContract(_bct,Resolution.Hour,true);   //<--this guy causes the error
