CVD (Cumulative Volume Delta) is OBV's sharper relative. Instead of counting a whole candle as 'buy' or 'sell' by its close, CVD uses actual aggressive (taker) trades: it adds taker buy volume and subtracts taker sell volume, then keeps a running total. It is the most precise classic measure of who is in control — and it is exactly what the live Order Flow dashboard on this site computes.
Reading the line
A rising CVD means aggressive buyers have dominated; falling means aggressive sellers. Its slope is the trend of control. The headline signal — as with the order-flow guides — is divergence: price making higher highs while CVD flattens or falls means the rally is running on thinner aggression, a warning that buyers are tiring even as the chart climbs.
Why it beats OBV
OBV guesses buy/sell from the close; CVD measures it directly from taker order flow, so it captures intrabar pressure OBV misses. CVD can also be split by market — spot CVD (real capital) vs. perp CVD (leverage) — letting you see, for example, real buyers accumulating while leverage stays flat. That spot/perp split is one of the cleanest crypto-native reads (Module 10).
