Hi

I have been trying to pull FRED data from quandl using the following code.

# In Initialize self.AddData(FRED, 'FRED/IPB52131N', Resolution.Daily) class FRED(PythonQuandl): '''Custom quandl data type for setting customized value column name. Value column is used for the primary trading calculations and charting.''' def __init__(self): self.ValueColumnName = "Value"

I'm trying to calculate the 12 month change of the index, but I keep running into errors "KeyError". I'm trying to run the Quandl data through self.History and slicing the Pandas dataframe.

Any help is appreciated!

Thanks
