Hi,
As I am working with the backtesting engine I am trying to set up the FineFundamentalUniverse in a seperate .py file. I am not successful in calling it from the main.py file and I get an Error Message "During the algorithm initialization, the following exception has occurred: TypeError : no constructor matches given arguments"
It would be great if I can understand how to set up the FineFundamental Universe in a separate file. I can dset up Portfolio construction classes in separate file but for some reason not with the FineFundamental model.
Thanks,
G

self.SetWarmUp(10)
self.SetCash(10000)
# Universe selection settings
self.UniverseSettings.Resolution = Resolution.Daily
self.UniverseSettings.DataNormalizationMode = DataNormalizationMode.Adjusted
self.UniverseSettings.ExtendedMarketHours = False
self.SetUniverseSelection(MyUniverseModel())

# code for the coarse filter

Hi Goofball,
The
FineFundamentalUniverseSelectionModel
class is not designed to be extended.Instead, MyUniverseModel can extend
FundamentalUniverseSelectionMode
.Please see the attached backtest for reference.
Best,
