To run this back-test accurately I need to pin down a few practical details: Market universe – do you want all U.S. listed common stocks, or another market (e.g., China A-shares, Europe, etc.)? Entry/exit prices – after ranking by volume at the close of day t: Buy at the next day’s open and exit at that day’s close, or Buy at the close of day t and exit at the next day’s close? Transaction costs – should we assume zero, or add a round-trip cost (e.g., 10 bp per side) given the very high turnover? Once these points are set I can generate the daily trade list (top-500 stocks by volume), feed it to the back-test engine, and return the performance metrics.
