Hi, why do I get the error message "AttributeError : 'QCAlgorithm' object has no attribute 'test'" when running the following code?
class MyQCA(QCAlgorithm):
def Initialize(self):
self.SetStartDate(2020, 9, 9)
self.test = "test"
self.UniverseSettings.Resolution = Resolution.Daily
self.symbol = Symbol.Create("TSLA", SecurityType.Equity, Market.USA)
self.SetUniverseSelection(ManualUniverseSelectionModel([self.symbol]))
self.AddAlpha(MyAlphaModel())
class MyAlphaModel:
def Update(self, algo, data):
algo.Debug(algo.test)
return []
def OnSecuritiesChanged(self, algo, changes):
pass

Hi Stinus,
The algo parameter in Update is an instance of a QCAlgorithm, and not of the algorithm, To address this, we would need to pass in the MyQCA object to the Alpha Model. For both of these, please see this thread for reference.
Best,
