Large Volume
Two studies that work together: detect large prints on a short timeframe chart (for example a 10-trade chart), then visualize them on your working chart.
Overview
Part of StarPentaPlus. Add Large Volume Detector on a short timeframe chart (for example a 10-trade chart) so large prints are caught as bars form. Add Large Volume Visualizer on the chart you trade from and point it at that Detector — bubbles, labels, and VWAP-style detail come from the stored events.
Sierra Chart includes a built-in large-volume study. This pair is built as a lightweight aggregator: volume is judged per bar on the detection chart (no sliding windows or long lookbacks), then drawn on your working chart. Prints that span multiple detection bars can be missed; that trade-off keeps the studies simple and fast.

Large Volume Detector
| Input Name | Input Description |
|---|---|
| Volume Threshold | Minimum bar volume that counts as a large-volume event. Events are stored for Large Volume Visualizer. |
Large Volume Visualizer
| Input Name | Input Description |
|---|---|
| Large Volume Detector Study ID | Chart and study instance of Large Volume Detector. Visualizer reads that study's stored events. |
| Font | Typeface for volume labels. |
| Font Size | Point size for volume labels. |
| Buy Bubble Color | Fill color for ask/buy volume bubbles. |
| Sell Bubble Color | Fill color for bid/sell volume bubbles. |
| Buy Text Color | Text color for ask/buy volume labels. |
| Sell Text Color | Text color for bid/sell volume labels. |
| Buy Text Background Color | Background color for ask/buy volume labels. |
| Sell Text Background Color | Background color for bid/sell volume labels. |
| VWAPLine Color | Color of the total VWAP extension line. |
| Ellipse Size | Radius in pixels of each volume bubble. |
| Extension Bars | How many bars to the right the VWAP / max-volume lines extend. |
| Display Mode | Show All Large Volumes draws every event. Combine at VWAP merges ask and bid at their VWAPs. Combine at Largest Volume places bubbles at the largest ask and bid prices. |
| Show Total VWAP | When Yes, draw the combined ask+bid VWAP line. |
| Volume Stacking Mode | Where volume labels stack: below the bar, above the bar, sells above / buys below, or buys above / sells below. |
| Draw Horizontal | When Yes, volume labels are horizontal. When No, they are stacked vertically. |
| Padding | Extra pixels around each volume label. |
| Gap | Pixels between stacked volume labels. |
| Vertical Adjustment | Offset in ticks from the candle before labels stack. Positive expands away from the candle (above labels move up, below labels move down). Negative moves labels toward the candle. |
