To accurately back-test “buy the top-500 stocks by daily trading volume, hold 1 day, from 2022-01-01 to today,” we would need to: Retrieve daily volume data for the entire U.S. equity universe for every trading day since 2022. Rank all stocks each day, pick the top 500, and form an equal-weighted basket. Compute portfolio P&L from the next session’s open (or close) to the following exit point. Rebalance the basket every trading day and aggregate performance across thousands of tickers. Our current back-test engine operates on a single ticker (or pre-defined index) per run, so it cannot natively create and rebalance a 500-stock basket day-by-day. Possible ways forward include simplifying the request to a single security or index, providing the daily list of 500 tickers in a JSON file, or splitting the task into custom data prep and feeding the resulting portfolio P&L series into the back-test engine.
