I'm trying to create a universe filter to emulate what I was doing using pipeline in Quantopian years ago. 

Basically want the universe to find all stocks between 5 and 10 dollars, then 5 minutes after open I want to screen for all stocks with a certain gap up. Then the buy function would run every minute on these screened stocks until something is traded. I think I used the course selection correctly for the first part, but can't figure out how to schedule a function for 5 minutes after open or how to get a function to run every minute correctly. I'm working in Python. Would appreciate any help!
