To run this back-test accurately I need to pin down a few practical details about how you’d like the “top-500-by-volume” rule implemented so that the signals I generate match your intent. 1. Universe • Do you want to look at all U.S. common stocks (≈4,000 names) each day, or is it acceptable to limit the universe to a standard index (e.g., Russell 3000 or S&P 500) from which we then pick the 500 most-active names? 2. Selection timing & execution price • Should the ranking be done on the same-day’s close and positions opened at that close, or opened next-day at the open? • Exit price after the 1-day hold: same-day close or next-day open/close? 3. Weighting scheme • Equal weight for all 500 positions, or volume-weighted / market-cap-weighted? 4. Transaction costs • Should we assume zero costs, or add a per-trade commission or slippage? 5. Data vendor preference • If you have a preferred data source (e.g., Bloomberg, CRSP, Polygon), let me know. Otherwise I’ll use the default equity feed. Once these are clarified I can build the retrieval plan, fetch the daily volume and price data, create the buy/sell signals, and run the strategy back-test from 2022-01-03 through today.
