Help with VWMA Indicator
When I copy paste this code I get this error: class VolumeWeightedAveragePrice(bt.Indicator):
AttributeError: 'Lines_LineSeries_LineIterator_DataAccessor_Indicat' object has no attribute '_addobserver'
I saw an earlier Post to this error but it didnt really help me. I also cant see where the error in the code is because for me it all makes sense. Thank you in Advance.
