Volume Bubbles flags candles with unusually large volume and marks their busiest price levels with a bubble that shows the traded value. Hover its legend row and click the gear to open the settings:
- Mode: flag candles by Z-Score (the default: volume far above the recent average) or by Absolute thresholds on their total traded value.
- Z-Score: Lookback sets how many bars it compares with, and three tiers set how unusual a candle must be.
- Absolute Thresholds: the value floors for the three tiers.
- Bucket Filter: which price levels on a flagged candle get a bubble. Min Bubble Value hides small ones, and Max Bubbles per Candle caps how many show.
- Style: the bubble shape, opacity and size. Turn off Show Stats Table here to hide the stats box.
Volume Bubbles is one of the built-in scripts in the Technical category of the indicator library.
