To run this back-test rigorously I need to pin down a few implementation details that aren’t fully specified yet: 1. Market universe • Do you want to screen the entire U.S. equity market (e.g., all common stocks on NYSE + NASDAQ + AMEX), or another universe (e.g., S&P 1500 constituents, China A-shares, etc.)? 2. Signal timing & execution price • Should the “top-500-by-volume” list be formed with yesterday’s volume, with trades executed at today’s open (typical), or do you prefer to buy at yesterday’s close once the ranking is known? 3. Portfolio construction • Equal-weight (i.e., 1/500 in each name), or another weighting scheme? • Rebalanced every trading day? 4. Frictions • Assume zero slippage/commissions, or incorporate transaction costs? 5. Benchmark • Any specific benchmark (e.g., SPY) you’d like reported alongside the strategy? With those items confirmed I can lay out the exact retrieval plan and launch the automated back-test for the 2022-01-01 → present period.
