CVD Divergence detects situations where price makes a new swing high or low, but the Cumulative Volume Delta (the running total of buy volume minus sell volume) fails to confirm the move. Unlike Delta Divergence which analyzes a single candle, CVD Divergence examines the trend of cumulative order flow over multiple bars, making it a structural rather than tactical signal.
What Is CVD?
Cumulative Volume Delta (CVD) is the running sum of delta across all candles in the visible range. Starting from a reset point (session open, day start, or the beginning of the chart), each candle’s delta (buy volume minus sell volume) is added to the running total.
- Rising CVD: Buyers have been more aggressive than sellers over the accumulation period.
- Falling CVD: Sellers have been more aggressive than buyers over the accumulation period.
When price and CVD move together, the trend is internally consistent. When they diverge, it signals that the underlying order flow does not support the price trend — a condition that often precedes reversals.
How CVD Divergence Works
The indicator identifies swing highs and swing lows in both price and CVD using a fractal-based method. It then compares the two series:
Bearish CVD Divergence
Price makes a higher high, but CVD makes a lower high (or fails to make a new high). This means:
- Price reached a new extreme, but the cumulative buying pressure behind it was weaker than the previous swing.
- The rally is losing order flow support.
- Sellers may be gaining control beneath the surface.
Bullish CVD Divergence
Price makes a lower low, but CVD makes a higher low (or fails to make a new low). This means:
- Price reached a new low, but cumulative selling pressure was weaker than the previous swing.
- The decline is losing order flow support.
- Buyers may be absorbing the selling pressure.
Settings
Detection Parameters
| Parameter | Description | Default |
|---|
| lookbackPeriod | Number of bars the indicator scans to find swing points for divergence comparison. Larger values detect longer-term divergences. | 20 |
| minDistanceBetweenPoints | Minimum number of bars that must separate two swing points used in a divergence. Prevents detecting divergences between adjacent candles. | 3 |
| fractalSize | The strength of the fractal used to identify swing highs and lows. A fractal of size N requires N bars on each side of the pivot to confirm it. Options: 3, 4, 5. | 5 |
| resetPeriod | How often the CVD running total resets to zero: none, day, week, month. Resetting prevents old data from dominating the cumulative calculation. | day |
The fractalSize parameter has a significant impact on signal behavior. A fractal size of 3 detects smaller, more frequent swings and produces more divergence signals. A fractal size of 5 requires stronger, more established swing points and produces fewer but more reliable signals. For swing trading, use 5. For intraday scalping, 3 or 4 may be more appropriate.
Visual Settings
| Parameter | Description | Default |
|---|
| dotSize | Size of the divergence marker dot in pixels. | 8 |
| showLines | Draw connecting lines between the two swing points that form the divergence. These lines make the divergence pattern visually obvious. | true |
| bullishColor | Color for bullish divergence markers and lines. | #84cc16 |
| bearishColor | Color for bearish divergence markers and lines. | #ef4444 |
Display Modes
CVD Divergence operates as both an overlay and a subchart:
- Overlay: Divergence dots and connecting lines appear directly on the price chart at the swing points where the divergence was detected.
- Subchart: The CVD line itself is plotted in a separate panel below the price chart, allowing you to visually compare the CVD trend with price action.
The combination of both views makes it straightforward to verify divergences: the connecting lines on the price chart highlight the divergence, and the subchart shows the actual CVD trajectory.
Reset Period
The reset period determines when the CVD running total resets to zero. This is an important parameter because CVD is a cumulative measure, and without resets, data from days or weeks ago can dominate the current reading.
| Reset Period | Behavior | Best For |
|---|
| none | CVD never resets. The running total accumulates from the first visible bar. | Long-term structural analysis |
| day | CVD resets at the start of each trading day (00:00 UTC). | Intraday trading (recommended default) |
| week | CVD resets at the start of each week. | Swing trading across multiple days |
| month | CVD resets at the start of each month. | Position trading |
Match the reset period to your trading session. If you trade intraday and close all positions by end of day, use day. If you hold positions for multiple days, week or none provides better context for multi-day divergences.
Alert Rules
| Event | Fires When |
|---|
| new_divergence | A new CVD divergence is confirmed after the fractal swing point is validated. The alert includes direction (bullish or bearish) and the bar timestamp. |
CVD Divergence vs. Delta Divergence
These two indicators are complementary, not redundant:
| Aspect | Delta Divergence | CVD Divergence |
|---|
| Scope | Single candle | Multi-bar trend |
| Speed | Real-time (fires on bar close) | Delayed (requires fractal confirmation) |
| Signal type | Tactical (entry timing) | Structural (trend exhaustion) |
| Noise level | Higher (many single-bar anomalies) | Lower (cumulative smoothing) |
| Best use | Scalp entries at known levels | Identifying trend reversals |
Practical Usage
Best Timeframes
| Timeframe | Suitability | Notes |
|---|
| 1m - 5m | Moderate | Many signals, frequent resets needed. Best with day reset. |
| 15m - 1h | Excellent | Strong balance of signal quality and frequency. |
| 4h - 1d | Excellent | Fewer signals but very reliable for swing trading. Use week or none reset. |
Confluence Setups
- Support/Resistance levels: CVD divergence at a major support or resistance level adds order flow confirmation to a structural price level.
- Volume Profile extremes: Divergence at a low-volume node (LVN) suggests the market is rejecting an attempt to push through thin liquidity.
- Absorption Alpha: When absorption markers appear at the same swing point where CVD divergence is detected, the signal is reinforced from both micro and macro perspectives.
Common Pitfalls
- Wrong reset period: Using
none on a 1-minute chart accumulates days of data, making the CVD line dominated by old history. Always match the reset period to your trading horizon.
- Fractal too small: A fractal size of 3 on a 1-minute chart fires frequently and many signals will be noise. Increase fractal size on lower timeframes.
- Ignoring the trend: CVD divergence in the middle of a strong trend may be premature. The most reliable signals occur at established price extremes where the trend is extended.
