Spot Cumulative Volume Delta (CVD) tracks the running total of net buying vs selling volume over time, showing sustained market pressure in either direction. It aggregates Volume Delta (VD) — the difference between buyer- and seller-initiated trades — across intervals (e.g., hourly, 10-minute) where USD or USD-related currencies serve as the quote.

CVD can be viewed per exchange or aggregated across exchanges to reveal persistent market momentum.
