To run this back-test rigorously I need to clarify (and potentially simplify) a few implementation details: 1. Trading universe • Do you want “all U.S. listed common stocks” (NYSE + NASDAQ + AMEX) ranked by daily dollar volume, or a different universe? 2. Execution price • Buy at today’s close and sell at tomorrow’s close (a 1-day holding period), or buy at tomorrow’s open and sell at tomorrow’s close? 3. Platform capability – single-ticker engines • The back-testing engine available here works on one ticker at a time. • To replicate a 500-stock portfolio we would normally need a portfolio back-tester, which is not (yet) exposed in this interface. Typical work-arounds: A. Use a representative ETF (e.g., SPY) instead of 500 individual stocks. B. Pre-compute your own daily index of the top-500-by-volume basket (outside this chat) and supply its price series as a single synthetic ticker. C. Alter the study to something the single-ticker engine supports (e.g., buy SPY on days when its own volume is in the top X % of its 1-year distribution). Please let me know which approach (or other adjustment) suits you best, and confirm the execution price convention you’d like. Once I have that, I can proceed with the data retrieval plan and back-test.
