To run a daily-rebalanced strategy that buys the 500 highest-volume stocks and holds them for one day, we first need to pin down a few practical details so the back-test can be implemented correctly: 1. Universe • U.S. listed stocks on NYSE + NASDAQ (default) – or do you have a different universe in mind? • Should OTC / small-cap exchanges be included? 2. Trade-price convention • Common practice is “buy next-day open, sell same-day close,” but you might prefer “buy today’s close, sell tomorrow’s close,” etc. Which assumption would you like? 3. Transaction costs / slippage • If you want to include commissions or a fixed spread, please specify (otherwise we’ll assume zero for a pure signal test). 4. Rebalance frequency • Daily (as you stated) – confirm that the portfolio should be fully refreshed every trading day, always holding exactly the 500 current high-volume names. 5. Benchmark (optional) • Do you want the results compared to an index such as the S&P 500, or just raw strategy returns? Once these items are confirmed I can generate the data-retrieval plan and run the back-test.
