Hello!
Can someone help me debug why I can't access Security.Fundamentals?
I am trying to access fundamental properties in the Alpha Class exactly like Jack Simonson does in the thread below.
However, in OnSecuritiesChanged, when I try to access Fundamentals with something similar to:
def OnSecuritiesChanged(self, algorithm, changes):
for added in changes.AddedSecurities:
added.Fundamentals._____
I run into an error where Fundamentals doesn't exist for added.
I am running substantially the same code, but my “added” type is a Securities.Equity.Equity, which I think may be the problem.

Hi Eric
Security.Fundamentals is a cached property, so if you did not get a FineFundemental data for the security before calling the property, you'll get a null value. Make sure you have passed a fine fundemental selection, and only worked on those output securities, or expand your selection if necessary.
