What CVD actually measures

Cumulative Volume Delta (CVD) tracks the running total of market-buy volume minus market-sell volume.

Rising CVD means aggressive buyers are dominating. Falling CVD means aggressive sellers are in control. A flat CVD suggests relative balance between both sides.

Why CVD matters

Price alone does not tell you how a move happened.

A market can rise because of weak buying pressure — for example, light volume and passive liquidity being lifted — or because of aggressive market buyers stepping in with size.

On a standard chart, both situations may produce the exact same green candle. CVD helps distinguish the difference.

How traders read CVD

  • CVD ↑ + price ↑: trend confirmation. Buyers are actively supporting the move.
  • CVD ↑ + price flat: absorption. Aggressive buyers are being absorbed by passive sellers at a specific level. This often appears before a breakout.
  • CVD ↓ + price ↑: bearish divergence. Price is climbing without strong buying participation.
  • CVD flat + price ↑: potential short squeeze without genuine spot demand. Usually a weaker move.

Important limitations

CVD is useful, but it is not a standalone edge.

Exchanges classify trades differently. Some provide direct buy/sell flags, while others require inference from bid/ask data. Spot and perpetual futures markets also behave differently at the microstructure level.

Treat CVD as a confirmation layer alongside price action, liquidity, and market structure — not as a single all-in-one signal.
