Key considerations include whether to restrict rankings to U.S.-listed equities or a specific index, as well as defining entry/exit timing for daily trades. Price data sources and friction costs, such as slippage or commissions, also require specification to ensure accurate signal generation.

Once parameters are finalized, the back-test will generate daily buy/sell signals for the top 500 volume-driven stocks, tracking performance from 2022 onward.
