To set up an accurate back-test I need to nail down a few practical details about the strategy and the data universe: 1. Exchange / universe • Should we screen the entire U.S. equity market (all NYSE-/NASDAQ-/AMEX-listed common stocks), or a specific subset (e.g., S&P 1500 constituents, only large-caps, etcETC--.)? 2. “Daily trading volume” definition • Do you want to rank by share volume (number of shares traded) or by dollar volume (shares × close price)? • Ranking is performed at the close of each trading day, correct? 3. Portfolio construction • Equal-weight all 500 selected names each day? • Rebalance daily (sell yesterday’s 500 at today’s open/close and buy today’s 500), or do you want any intra-day assumptions? 4. Transaction cost assumptions • Do you want to include commissions and/or slippage? If so, please specify (e.g., 2 bpBP-- round-trip). 5. Price used for fills • Use the official close for both entry and exit, or buy at tomorrow’s open and sell at tomorrow’s close, etc. With these points clarified I can generate the retrieval plan, pull the necessary data, and run the back-test.
