To run this back-test I’ll need to clarify three practical details before we start pulling data: 1. Universe • Should we use all U.S.-listed common stocks (NYSE + NASDAQ + AMEX), or another market/universe? 2. Weighting method • Equal-weight each of the 500 names every day, or weight by (say) dollar volume or market-cap? 3. Trade-price convention • Volume for “today” isn’t known until the close, so a typical implementation is: – At today’s close, rank by today’s dollar volume, – Buy the top-500 names at next day’s open, – Close all positions at that day’s close (1-day hold). Does that match your intent? Once I have these three points confirmed I can lay out the data-retrieval plan and start the automated back-test.
