Cumulative Delta (CVD) & Divergence
A running scoreboard of aggression — and what it whispers at highs and lows.
In this lesson you'll
- Compute cumulative delta from bar deltas
- Use rising/falling CVD to judge who is in control
- Spot CVD divergence at swing highs and lows
Read CVD alongside price. Price up + CVD up = a healthy, confirmed trend (aggressive buyers genuinely driving it). Price up + CVD flat/down = the move lacks real aggressive demand — a possible fakeout. Falling CVD = sellers in control; flat CVD = participation drying up.
CVD divergence
The highest-value CVD signal is divergence at an extreme:
- Bearish divergence (at highs): price makes a higher high but CVD makes a lower high (or stalls) → buyer exhaustion / absorption.
- Bullish divergence (at lows): price makes a lower low but CVD makes a higher low → hidden buying / selling losing control.
Key takeaways
- CVD = running sum of bar deltas; a scoreboard of net aggression over time.
- Price up + CVD up = confirmed; price up + CVD flat/down = suspect.
- Bearish divergence: higher price high, lower CVD high (exhaustion at highs).
- Bullish divergence: lower price low, higher CVD low (hidden buying at lows).
- CVD is a condition that improves odds — not a standalone trigger.

Why that's off: +150 is only the last bar's delta, not the running total.
Why that's off: +650 ignores the −300 bar.
Why that's off: Sign error — the positives outweigh the negative.
CVD is the running sum: 500 − 300 + 150 = +350.
Why that's off: Confirmation would require CVD to also make a higher high.
Why that's off: Divergence at an extreme is one of the more meaningful CVD reads.
Why that's off: It shifts odds, but markets can stay divergent for a while — never a guarantee.
When price pushes to a new high but aggressive buying (CVD) fails to confirm with its own new high, it signals exhaustion/absorption — a bearish divergence. It raises the odds of a turn but is not a guarantee.
Why that's off: That's an ideal environment for CVD.
Why that's off: Failed breakouts are a classic, favorable CVD setup.
Why that's off: An aggressor flag makes the data more reliable, not less.
Thin markets are CVD's weak spot: a single oversized order distorts the running total, and low participation exaggerates signals. CVD is most trustworthy in liquid, centralized markets with good data.
