Hello, I want to get a list of securities sorted by ROIC, for this I used the coarse-fine universe method in the lab algorithm (with PERatio as example) to test it but when I replace the PERatio by ROIC I have this bug;
Cannot convert object of type Python.Runtime.CLRObject to IComparable
at FineSelectionFunction
def FineSelectionFunction(self, fine):
# sort descending by P/E ratio
sortedByPeRatio = sorted(fine, key=lambda x: x.OperationRatios.ROIC, reverse=True)
# take the top entries from our sorted collection
return [ x.Symbol for x in sortedByPeRatio[:self.__numberOfSymbolsFine] ]
# __numberOfSymbolsFine is defined I use the same params as the example with the PERRatio
Thanks for you help.
