# Volume Zones Internal Visualizer

Volume Zones Internal Visualizer is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®.

Volume Zones Internal Visualizer rebuilds every chart candle from lower-timeframe data, boxing its range and shading where volume concentrated inside it. The busiest intrabar close becomes a Peak Activity Level that extends forward until crossed: per-candle volume structure at a glance.

**Volume Zones Internal Visualizer** opens each chart candle to show where volume accumulated inside it. Lower-timeframe data assembles an [intrabar volume profile](https://www.luxalgo.com/library/concept/volume-profile/) for every candle, rendered as the indicator's own candlestick type: an outlined box for the range, a solid-colored zone over the heaviest volume, a transparent zone over the thinnest, and a line at the close of the single busiest lower-timeframe candle, the Peak Activity Level (PAL). It reads best with the regular chart hidden, or in a pane beside a conventional one.

## How to Trade the Volume Zones Internal Visualizer?

- **Solid zones**: the highest-volume region of the candle, where that session's business concentrated and acceptance is strongest.
- **Transparent zones**: the least-traded stretch of the range, more likely to be traversed quickly on a revisit.
- **PAL lines**: each candle's peak-activity close extends into later sessions as a working level; once price crosses a PAL it counts as mitigated and stops displaying.

Unmitigated PALs mark the close of the busiest lower-timeframe candle inside earlier candles, so many traders study the reaction when price revisits one before timing entries and exits.

## Volume Zones Internal Visualizer Settings

- **Row Size**: the number of rows in each candle's internal profile, the granularity of the zones.
- **Intrabar Timeframe**: which lower timeframe supplies the calculation data.
- **Show Last Unmitigated PALs**: how many uncrossed PALs stay extended forward.
- **Style**: element toggles and color controls.

## Frequently Asked Questions

### Does it replace normal candlesticks?

No. It complements them. The boxes carry volume structure rather than the usual open/close emphasis, so hide the standard chart for clarity or run the visualizer in an adjacent pane.

### How does it differ from a footprint-style display?

[Volume Footprint](https://www.luxalgo.com/library/indicator/volume-footprint/) dissects per-candle activity in fuller detail; the Internal Visualizer distills each candle to its extremes (heaviest zone, thinnest zone, and the PAL), which keeps the read fast.

### Is the Volume Zones Internal Visualizer free?

Yes. Grab it from the LuxAlgo Library at no cost, or run it from this page in Quant, our coding agent. You can also copy the source code from this page and run it anywhere Pine Script® runs.
