Hi all,

Does anyone know why I would be getting this error?

'XLB' wasn't found in the TradeBars object, likely because there was no-data at this moment in time and it wasn't possible to fillforward historical data. Please check the data exists before accessing it with data.ContainsKey("XLB") in DataDictionary.cs:line 228. 

This error doesn't really help me track this down to a line of code for debugging. Anyone know how to see which line of code caused this error on the Python side of the house?
