📘 Overview
Better Volume Z-Score is an enhanced volume analysis indicator inspired by the classic Better Volume concept.
This tool goes far beyond the basics by incorporating:
-
✔ Z-Score-based volume spike detection
-
✔ Flexible Churn zone recognition (volume + low range)
-
✔ Dynamic volume classification with color-coded histograms
-
✔ Built-in countdown timer to next bar close
-
✔ Optimized for high-speed testing in Strategy Tester (MQL5 Market-compliant)
Perfect for scalping, intraday, and swing trading strategies, this indicator reveals the "quality of volume" and helps identify meaningful turning points and accumulation/distribution zones.
🧠 Core Features
✅ Color-coded Volume Bars (Histogram)
| Color | Meaning |
|---|---|
| 🔴 Red | High volume on rising bar (buy pressure) |
| 🔵 Blue | High volume on falling bar (sell pressure) |
| 🟣 Purple | Z-Score spike (statistically abnormal volume) |
| ⚫ Gray | Churn zone – low range but high volume (congestion) |
| 🟠 Orange | Normal volume |
| ⚪ Silver | Very low volume (quiet market) |
✅ Z-Score Spike Detection
Calculates the standard deviation of volume over a rolling window ( maPeriod ).
Bars that exceed the zScoreThreshold are flagged as statistical spikes, helping to identify sudden market interest or large orders.
✅ Churn Detection
Flags bars with small price range and above-average volume, indicating potential accumulation or distribution zones before breakouts.
Condition:
-
Range < previous bar's range × churnRangeFactor
-
and Volume >= MA
✅ Countdown Timer
A live countdown ("Remaining: mm:ss") is shown in the lower right corner of the chart to indicate the time remaining until the next bar – useful for precision timing in active trading.
→ Automatically disabled in Strategy Tester to avoid GUI overhead.
