The back-test framework for volume-based screening requires precise parameters. The universe definition must clarify whether it includes all U.S. common stocks on NYSE and NASDAQ or a narrower subset like Russell 3000 constituents. Exclusions of ADRs, ETFs, and preferred shares are standard but need explicit confirmation. Execution rules demand specificity on ranking timing—using end-of-day volume for next-day entry or same-day close—to ensure signal consistency.

Weighting strategies and cost assumptions remain critical. Equal-weight allocation across the top 500 stocks daily versus alternative methodologies could significantly alter returns. Slippage and commission costs, though often overlooked in preliminary tests, should be addressed for realistic modeling. Computational constraints also arise when processing full U.S. equity universes, necessitating either a scaled-down approach or a phased implementation plan to manage data retrieval costs effectively.
