CVD Z-Score

Category: Community

The CVD Z-Score indicator measures cumulative buying versus selling pressure, normalized as a statistical z-score, to detect volume-price divergences and accumulation/distribution phases. It displays a smoothed oscillator that highlights when volume delta reaches statistical extremes, identifies effort-versus-result efficiency, and flags potential spot accumulation setups where rising CVD coincides with flat price action and declining open interest.

USAGE

Reading the Z-Score Oscillator

The main line oscillates around zero.

Positive values: Net buying pressure is above its recent average.

Negative values: Net selling pressure is dominant.

Colors: The line is blue when bullish and pink when bearish.

The neutral zone sits between +1.0 and -1.0. Values beyond ±1.0 indicate meaningful directional pressure, while values beyond ±2.0 are considered statistically extreme.

Climax Zone Warnings

When the Z-Score first crosses above +2.0 or below -2.0, a diamond marker appears. These climax entries indicate that buying or selling pressure has reached a statistical extreme—a condition that often precedes exhaustion or reversal. A subtle background highlight persists while the score remains in the extreme zone.

Spot Accumulation Signals

Blue circle markers appear at the bottom of the oscillator when three conditions align:

CVD Z-Score is positive and rising (buying pressure increasing).

Price action is flat (range is contained within 1.5x ATR).

Open Interest is declining (futures positions are unwinding).

This suggests buying is occurring in the spot market while futures traders reduce exposure—a classic accumulation pattern.

Dashboard

The optional dashboard displays three real-time metrics:

Z-Score: Current value with trend arrows and zone highlighting (Green for overbought, Red for oversold).

Efficiency: Categorizes the market as "Breakout" (price responding to volume), "Churn" (high volume, stalling price), or "Balanced."

Phase: Displays "Accumulation," "Climax," or "Neutral."

DETAILS

CVD Calculation

Cumulative Volume Delta (CVD) is built bar-by-bar:

Bullish bars (Close > Open): Full volume added to the total.

Bearish bars (Close < Open): Full volume subtracted.

Doji bars: Zero contribution.

Z-Score Normalization

The raw CVD is standardized using the following formula: $$Z = \frac{CVD - SMA(CVD, n)}{\sigma(CVD, n)}$$ Where $n$ is the lookback period and $\sigma$ is the standard deviation. A smoothing EMA is then applied to reduce noise.

Efficiency Analysis (Effort vs. Result)

This compares price movement to CVD movement over a 5-bar window.

High Efficiency (> 5): "Breakout"—Price moves significantly relative to delta.

Low Efficiency (< 0.5): "Churn"—High delta activity but price is stalled, signaling absorption or distribution.

Open Interest Integration

The indicator fetches OI data (default: BINANCE:BTCUSDT.P_OI). Declining OI during rising CVD and flat price suggests buying pressure stems from spot markets rather than leveraged futures.

Disclaimer: This indicator measures statistical extremes in volume delta and does not predict price direction. Accumulation signals identify a specific pattern that does not guarantee a move. Climax events may not result in reversals. This is not financial advice; past performance does not guarantee future results.
