Hello~! I am a beginner with Quantopian. It's not easy to do while learning Python as well as Quantopian.

I would like to construct a universe with the following conditions.

-Excluding companies with negative operating cash flow and net income
-Excluding companies with suspension of transactions
-etf, excluding preferred stock

What should I do?

Thank you for reading my question, Have a good night~
