Unless you direct me otherwise, I will adopt the following sensible defaults: Universe: All common stocks listed on NYSE + NASDAQ + NYSE Arca (i.e., the full U.S. equity universe). Daily-volume metric: total shares traded (not dollar volume). Trade timing: Rank stocks by the prior day’s volume (T-1 close). Enter positions at the next day’s open (T). Exit all positions at that same day’s close (T). , slippage, and borrow fees: ignored (gross returns). Rebalance frequency: daily (every trading day from 2022-01-03 to the latest available data). If these assumptions match your intent, just let me know and I’ll run the back-test. If you’d like anything changed—different universe, dollar volume instead, include costs, alter entry/exit timing—tell me and I’ll adjust accordingly.
