To run this back-test robustly I need to pin down a few practical details and confirm that the test scope matches what the system can execute: 1. Market universe • Are we working with U.S.–listed equities (NYSE + NASDAQ), or another market? . Ranking rule • “Top 500 by daily trading volume” – is that by dollar value (shares × price) or by share count? . Trade timing • Do we buy the portfolio at today’s close (after seeing today’s volume) and exit at tomorrow’s close, or buy at tomorrow’s open instead? . Portfolio construction • Equal-weight each of the 500 names for the one-day hold? . Tool limitation • The built-in back-test engine runs on one ticker at a time. For a many-stock strategy we need to aggregate outside that engine (i.e., pull volume and price for every stock each day, form the 500-stock basket, compute the equal-weighted return). That requires a larger custom data pull and calculation step. If you’re comfortable with that approach, I can proceed; otherwise we could approximate with a narrower subset or a representative ETF. Please let me know your preferences on the above so I can set up the back-test correctly.
