To run this back-test accurately I need to clarify a few practical details that will determine how we set up the data retrieval and the daily rebalancing logic: 1. Universe • Which market/universe should we pull the "top-500-by-volume" from each day? • If it’s U.S. equities, is it the full listed universe (NYSE + NASDAQ + AMEX) or a sub-set such as the S&P 1500? 2. Pricing & execution convention • Should we assume: – Buy at the close on day T (after ranking by that day’s volume) and sell at the close on day T + 1? – Or buy at the next open and sell at the following close? • Which price field (close or open) should drive fills? 3. Transaction costs & slippage (if any) • Do you want to ignore them, or apply a per-trade cost assumption? 4. Weighting scheme • Equal-weight each of the 500 names every day (default), or volume-weighted / market-cap-weighted? Once I have these four items confirmed I can automatically pull the historical volume data, generate the daily portfolios, and feed the trade signals into the back-testing engine.
