I'm trying to access all the objects in my current universe with the following code:

for x in self.Securities:

However, "x" just ends up being a short string containing the ticker symbol and some other garble, instead of a complete QuantConnect.Securities.Security object, which is what the docs say it should be. So I can't access the needed object properties like Symbol, Price, etc. Does anyone know why I'm getting a string instead of the expected object? Many thanks!
