Suppose we have an algorithm architecture like:
class MyAlgorithm(QCAlgorithm):
def Initialize(self):
self.SetUniverseSelection(**kwargs)
self.SetAlpha(MyAlphaModel()):
def OnData(self, data):
class MyAlphaModel(AlphaModel):
def __init__(self):
pass
def OnSecuritiesChanged(self, algorithm, changes):
pass
def Update(self, algorithm, data):
insights = []
return insightsThe objective is to take the dataframe of security close prices, apply some function MyFunc() to it, and emit a single scalar value for each security as an Insight object.
def MyFunc(self, data):
for security in self.Securities:
# do something
return # some scalar value for each security- Should MyFunc() be called inside MyAlphaModel.Update or OnData?
- Is self.Securities automatically populated with security objects from the set Universe, or should an empty list be instantiated and securities appended in MyAlphaModel.OnSecuritiesChanged()?
