Cumulative Volume Delta (CVD) is a running total of aggressive buying volume minus aggressive selling volume, used to reveal the order flow behind a price move rather than just the price itself. Because a candlestick only shows where price ended up, CVD helps traders see whether that move was driven by real conviction or by a thinner, more fragile push.
What CVD reveals behind candlestick movement
Every trade that executes against the order book is either a market buy hitting the ask or a market sell hitting the bid. CVD adds up that difference over time, tick by tick. When price rises and CVD rises with it, buyers are genuinely paying up for the move. When price rises but CVD flattens or falls, the rally is being carried by thin liquidity or short covering rather than fresh demand, which makes it easier to reverse.
Spot CVD versus futures CVD
Comparing spot CVD against perpetual futures CVD tells you who is actually leading a move. When spot CVD trends steadily upward while futures CVD stays flat, buyers are accumulating coins outright rather than borrowing exposure through leverage. That kind of demand tends to hold up better under pressure than a rally built mostly on futures positioning, since there is no funding cost pushing traders to unwind it.
A practical scenario
Imagine price probes a daily S1 pivot three separate times over a session. On the first two tests, CVD makes a new low alongside price. On the third test, price matches the earlier low but CVD prints a higher low, a classic bullish divergence. That mismatch suggests sellers are running out of ammunition even though price hasn't moved yet.
Practical execution rules
- Identify a key daily pivot level, such as S1, S2, R1, or R2, before the session begins.
- Wait for price to probe that level and form a clear divergence against the CVD line on the 15-minute chart.
- Enter on the close of the first candle that confirms the direction implied by the divergence, rather than anticipating it early.
