ConstantAlphaModel Overloads

[DerekMelchin]

Expected Behavior

This works without error:

ConstantAlphaModel(InsightType.PRICE, InsightDirection.UP, timedelta(1), weight=0.1)

Actual Behavior

During the algorithm initialization, the following exception has occurred: Trying to dynamically access a method that does not exist throws a TypeError exception. To prevent the exception, ensure each parameter type matches those required by the 'datetime.timedelta'>) method. Please checkout the API documentation.
  at initialize
    self.add_alpha(ConstantAlphaModel(InsightType.PRICE, InsightDirection.UP, timedelta(1), weight=0.1))
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 in main.py: line 15
 No method matches given arguments for .ctor: (<class 'QuantConnect.Algorithm.Framework.Alphas.InsightType'>, <class 'QuantConnect.Algorithm.Framework.Alphas.InsightDirection'>, <class 'datetime.timedelta'>) (Open Stack Trace)

Instead, we are forced to write

ConstantAlphaModel(InsightType.PRICE, InsightDirection.UP, timedelta(1), None, None, 0.1)

Potential Solution

N/A

Reproducing the Problem

class UpcomingIPOsExampleAlgorithm(QCAlgorithm):
    
    def initialize(self) -> None:
        self.set_start_date(2024, 9, 1)
        self.set_end_date(2024, 12, 31)
        self.set_cash(100000)
        self.add_universe(self.universe.dollar_volume.top(5))
        self.add_alpha(ConstantAlphaModel(InsightType.PRICE, InsightDirection.UP, timedelta(1), weight=0.1))
