To run this back-test robustly we need to pin down a few implementation details that the current request leaves open: 1) Market universe - Are we talking about all U.S. listed common stocks (NYSE + NASDAQ), only the S&P 500 constituents, or another universe? 2) Trade timing - Should the portfolio be formed at the close of day t using that day’s volume ranking and liquidated at the next day’s close (t + 1), or do you prefer using the next day’s open for entry/exit? 3) Weighting & costs - Equal-weight each of the 500 names? Ignore transaction costs/slippage, or apply an estimate? 4) Turnover constraints - Because this strategy changes holdings every single day, turnover is extremely high. If you have any turnover or liquidity constraints beyond "top 500 by volume," please specify. Once those points are locked down I can generate the data-retrieval plan, pull the required volume data and price series, and run the back-test from January 2022 through today.
