BTC Price-Volume Efficiency Z-Score (PVER-Z)

Overview:
This PVER-Z Score measures Bitcoin’s price movement efficiency relative to trading volume, normalized using a Z-Score over a long-term 200-day period.
It highlights statistically rare inefficiencies, helping investors spot extreme accumulation and distribution zones for systematic SDCA strategies.

Concept:
- Measures how efficiently price has moved relative to the volume that supported it over a long historical window (Default 200 days) but can be adjustable.
- It compares cumulative price changes vs cumulative volume flow.
- Then normalizes those inefficiencies using Z-Score statistics.

How It Works:

1. Calculates the absolute daily price change divided by volume (price-volume efficiency ratio).

2. Applies EMA smoothing to remove noisy fluctuations.

3. Normalizes the result into a Z-Score to detect statistically significant outliers.

4. Plots dynamic heatmap colors as the efficiency score moves through different deviation zones.

5. Background fills appear when the Z-Score moves beyond ±2 to ±3 SD, signaling rare macro opportunities.


Why is Bitcoin price rising while PVER-Z is falling toward green zone?

1. PVER-Z is not just "price" — it's price change relative to volume. PVER-Z measures how efficient the price movement is relative to volume. It's not "price going up" or "price going down" directly. It's how unusual or inefficient the price versus volume relationship is, compared to its historical average.
2. A rising Bitcoin price + weak efficiency = PVER-Z falls.
If Bitcoin rises but volume is super strong (normal buying volume), no problem, the PVER-Z stays normal. If Bitcoin rises but with very weak volume support, PVER-Z falls.

***Usage Notes***:

- Best used on the daily timeframe or higher.

- When the Z-Score enters the green zone (-2 to -3 SD), it signals a historically rare accumulation zone — favoring long-term buying for SDCA.

- When the Z-Score enters the red zone (+2 to +3 SD), it signals overextended distribution — caution recommended.

- Designed strictly for mean-reversion analysis, no trend-following signals.

- The red zone on a proper Z chart would be -2SD to -3SD and +2SD to +3SD for the green zone. At the time of publishing I do not know how to adjust the values on the indicator itself. The red zone at -2SD is actually +2 Standard Deviations on a Z Score SD Chart. (overbought zone).

- Your green zone at +2SD is actually -2SD Standard Deviations (oversold zone).

- Built manually with no reliance on built-in indicators

- Designed for Bitcoin on the 1D, 3D, or Weekly timeframes. NOT for intraday trading.
