I cannot seem to figure out how to load symbols into course from a Universe of the Russell 1000. I am trying to reproduce an algorithm based on this blog post by Ceasar Alverez. I am starting with Michael's UniverseSelectionAlgorithm.

Has anyone out there loaded a bunch of symbols into "course"?

In this algorithm, I am getting a runtime error that I have not added any symbols. Am I supposed to add 1000 symbols?
