# Volume Bars

> Bars showing the traded volume of each candle in a separate pane.

Updated: 2026-10-25T00:01:52.000Z · https://chartrider.com/docs/indicators/volume/

## What you see
One bar per candle in its own pane, all in the same color. The highest visible bar fills the pane and the others are scaled to it, so the pane always shows volume relative to the current view.

## How it is calculated
There is no calculation: each bar is the volume of its candle as it comes with the market's candle data. Bars are not colored by candle direction.

## How to read it
- Breakouts on rising volume are more trustworthy than breakouts on falling volume.
- Volume spikes often mark capitulation or exhaustion at the end of a move.
- Pullbacks on low volume within a trend suggest the trend is intact.
- Whether a bar is unusual only becomes clear against an average of recent volume.

## Using it in strategies
Output: `value` (the candle's volume). In the [Trade Setup](https://chartrider.com/docs/strategies/trade-setup/), "Compare" checks it against a fixed amount. Relative checks are easier in [WickScript](https://chartrider.com/docs/wickscript/), which has the series `volume`, e.g. `volume > 2 * sma(volume, 20)` for a volume spike. With `use indicator "Volume Bars" as vol` you read this indicator as `vol.value`.

## Settings

Open the settings with the slider icon next to the indicator (Indicators, `F3`). Numeric settings can be swept as Step 1 / Step 2 parameters when you run a strategy.

| Setting | Type | Default | Description |
|---|---|---|---|
| Bar Color | Color | `#7464ff` |  |
| Height | Number | `70` | Height of the pane in pixels. (min 30) |

## Outputs

These values can be used in Trade Setup triggers, filters and exits (see [Trade Setup](https://chartrider.com/docs/strategies/trade-setup/)) and in WickScript.

| Output | In WickScript | Description |
|---|---|---|
| value | `value` |  |

## Use in WickScript

`use indicator` creates this indicator inside a script, with settings by their ID. Each output is a field of the name after `as`. See [WickScript indicators](https://chartrider.com/docs/wickscript/indicators/).

```wickscript
wickscript 1
indicator "Volume Bars from the list" in pane
use indicator "VOL" as myVol
show myVol.value as line "value"
```
