To set up this back-test accurately I need to pin down several details that aren’t specified yet: 1. Universe • Should we screen only U.S. listed common stocks (‐ADR, ETF, preferreds excluded), or a different universe? 2. Ranking logic & trade timing • Do we rank stocks on the prior trading day’s volume, buy them at the next day’s open and liquidate at that day’s close (1-day holding period)? • Or do you intend “buy at today’s close, sell at tomorrow’s close”? 3. Position sizing • Equal-weight across the 500 names each day? • Any cap on position size or liquidity filter besides volume rank? 4. Costs & slippage • Should we include transaction costs or ignore them? 5. Benchmark (if any) for relative performance. Our current back-test engine is designed for a single ticker or a predefined list; implementing a daily-changing 500-stock basket is still possible, but it requires clarifying the points above so I can script the data pulls and portfolio construction correctly. Let me know your preferences and I’ll proceed.
