I already checked that using the algorithm framework the same algo can have multiple alpha models. Now I'm interested to learn if it would be also possible to have multiple universe selection models feeding different alpha models, all within the same algo?

Hi Leoandro,
If the Universes are from different classes, we can iterate through the UniverseManager and extract the class information inside the alpha model to see which Universe the securities are from. I've shown this in the attached backtest. If the Universes are from the same class, then I'd suggest performing two filters for each Universe inside the same class, and return the combined list, and check which list a security is from in the Alpha model.
Best,

Hi Shile, what about chained universes within the algorithm framework?

Hi Papa Bear
You can take a look at this doc. Although classical approach was used there, it can be easily modified into framework with ”AddUniverseSelection” method.
