To run this back-test correctly I need to clarify a few practical details that are not fully specified in your request. Once I have them, I can generate the daily portfolio, feed the signals into the engine and return the full performance report. Market universe: Should we look at all U.S. listed common stocks (NYSE + Nasdaq + Amex), or a narrower universe (e.g., only S&P 1500 constituents)? Volume measurement: Do you want to rank by the day’s total dollar volume (price × shares traded) or by share volume only? Trade price assumptions: Buy at the day’s close and sell next day’s close (close-to-close return), or buy next day’s open and sell that same day’s close (close-to-open then open-to-close)? Frictional costs: Should we include estimated transaction costs (commissions + slippage)? If yes, please specify a per-trade bps figure (e.g., 5 bp per side). Rebalancing on non-trading days: If the market is closed on the holding-period exit date (e.g., holiday), should we exit on the next trading day?
