Ultra Volume Detector

Native Volume — Auto Levels + Ultra Label

What it does
This indicator classifies volume bars into four categories — Low, Medium, High, and Ultra — using rolling percentile thresholds. Instead of fixed cutoffs, it adapts dynamically to recent market activity, making it useful across different symbols and timeframes. Ultra-high volume bars are highlighted with labels showing compacted values (K/M/B/T) and the appropriate unit (shares, contracts, ticks, etc.).

Core Logic

Dynamic thresholds: Calculates percentile levels (e.g., 50th, 80th, 98th) over a user-defined window of bars.

Categorization: Bars are colored by category (Low/Med/High/Ultra).

Ultra labeling: Only Ultra bars are labeled, preventing chart clutter.

Optional MA: A moving average of raw volume can be plotted for context.

Alerts: Supports both alert condition for Ultra events and dynamic alert() messages that include the actual volume value at bar close.

How to use

Adjust window size: Larger windows (e.g., 200+) provide stable thresholds; smaller windows react more quickly.

Set percentiles: Typical defaults are 50 for Medium, 80 for High, and 98 for Ultra. Lower the Ultra percentile to see more frequent signals, or raise it to isolate only extreme events.

Read chart signals:

Bar colors show the category.

Labels appear only on Ultra bars.

Alerts can be set up for automatic notification when Ultra volume occurs.

Why it’s unique

Adaptive: Uses rolling statistics, not static thresholds.

Cross-asset ready: Adjusts units automatically depending on instrument type.

Efficient visualization: Focuses labels only on the most significant events, reducing noise.
