Hi Choo,
Welcome to QuantConnect! Yes we definitely offer the functionality that you describe, it is called universe selection. You can choose universe selection template when you create a new algorithm to get started.
Here is the coarse-fine universe selection template. It selects symbols by two rounds: first round is coarse selection, which selects the top 100 from the whole universe based on daily dollar volume, and then second round is fine selection, which selects the top 5 from the result of coarse selection based on P/E ratio. Again it’s just a template, you have so much freedom to do whatever you want.
Hope it helps!
