To run this back-test accurately we need a few additional details and, importantly, a practical way to implement “top-500-by-volume” inside the tool framework. Key points that need clarification or agreement: 1. Universe definition • Should we consider all U.S. listed common stocks (NYSE + NASDAQ) or restrict to a subset (e.g., current S&P 500 constituents)? • Note that the larger the universe, the more data we must load and rank each day. 2. Weighting & execution price • Equal-weight across the 500 names, or volume-weighted, or some other scheme? • Buy at that day’s close and exit at the next day’s close (standard 1-day holding period), or another convention (open-to-open, close-to-open, etc.)? 3. Operational feasibility in this environment • Our built-in back-test engine is designed for one-ticker strategies. To approximate a 500-stock basket we can: a) Compute daily portfolio returns offline (ranking and equal-weighting the 500 names) and then feed those portfolio returns into the engine as a synthetic “ticker”; or b) Work with a narrower proxy (e.g., S&P 500 ETF or current S&P 500 constituents) if that meets your analytical goal. Please let me know your preference on the above so I can set up the data retrieval plan and run the back-test.
