VWAP Optimization Starts with the Anchor and Volume Source

VWAP divides accumulated price-times-volume by accumulated volume from a defined starting point. Specify the price source and reset rule. A session reset, a calendar-week reset, a fixed event anchor and a rolling five-day window are different calculations. A weekly anchor is not equivalent to retaining exactly five trading days at every bar.

Check the volume source and coverage. The calculation weights the volume supplied for the chosen symbol; unavailable volume or zero accumulated volume needs explicit handling. Volume from one venue or tick activity is not automatically the total traded volume of the whole market. A smaller chart bar does not make VWAP meaningless merely because that bar contributes a small share of accumulated volume.

Define the strategy separately from the reference line. A return-to-VWAP entry and a continuation crossover have different meanings. If using bands, state whether distance is measured in percentage points or a specified standard-deviation calculation. A drawn band changes trades only when the order conditions use it. Keep the chart timeframe separate from exposed strategy inputs; a calculation-timeframe input is not necessarily a chart-timeframe switch.
