I understand the idea: each trading day, form an equal-weighted portfolio consisting of the 500 U.S. stocks that showed the highest dollar trading volume that day, hold that basket for exactly one trading session, then repeat the process from the start of 2022 through today

Before I can execute a back-test, two practical issues need clarification: 1. Supported engine scope • The back-testing engines currently exposed in this workspace operate on a single ticker at a time. A daily-rotating, 500-stock basket therefore exceeds the engines’ present capability. • If you’re comfortable with an approximation, I can test a liquid index (e.g., the S&P 500 ETF “SPY”) instead. This would answer “what if I held the whole S&P 500 for one day and kept re-entering,” but it would not filter by volume. 2. Parameter detail (if we do find a suitable engine) • Price type for entry/exit (open vs. close prices). • Any . • Universe or exchange limits (NYSE + NASDAQ + AMEX?)

Please let me know which route you’d like to take: A. Proceed with an index-level proxy (fastest). B. Wait while I build a custom multi-asset script outside this chat (would require an offline solution). C. Refine the request in another way. I’m ready to move forward as soon as I have your preference
