Volume Bubbles: Percentile Clusters and Buy-Sell Volume Delta
Summary
The indicator marks unusually active bars with bubbles grouped into small, medium, and big tiers. Its defaults use recent volume percentiles, with separate short, medium, and long lookbacks contributing to a configurable consensus. Users can detect clusters from volume, lower-timeframe buy-sell delta, or a combination of the two, and classify direction from candle color, delta sign, or agreement between them.
Bubble size and labels can display volume, delta, or relative volume, while colors distinguish buy, sell, and mixed classifications. Alerts are available for cluster tiers. The script also provides a warning when the symbol has no volume data. These features describe a visualization and filtering tool, not a demonstrated trading strategy: the supplied material gives no performance evidence or rules for entries, exits, or risk. Delta depends on lower-timeframe data availability, and the script notes that label and tooltip details are limited for older bubbles.
Key ideas
- Volume clusters are tiered using percentile thresholds against recent history.
- Multiple lookback windows can require agreement before a cluster is confirmed.
- Detection can use total volume, lower-timeframe delta, or both.
- Cluster direction can follow candle direction, delta direction, or require them to agree.
- The indicator visualizes activity and offers alerts but does not establish trading performance.
