I understand the strategy concept, but to run a proper back-test I need to clarify how you’d like the universe handled: The built-in back-test engine here evaluates one ticker (or index) at a time. For a cross-sectional “top-500-by-volume” portfolio, we would normally need daily data for the whole market, generate the 500-stock list each day, and aggregate the returns – something our current single-ticker engine cannot execute directly.
