# Delta Volume

> Per-bar difference between buy and sell volume.

## Overview

**Delta Volume** measures the difference between buy volume and sell volume for each individual candle. Unlike CVD, which accumulates over time, Delta Volume resets every bar, giving you a clean read on who dominated that specific period.

* **Positive delta** = more aggressive buying (volume executed at the ask).
* **Negative delta** = more aggressive selling (volume executed at the bid).

## How It Works

For each bar:

```
Delta[n] = buyVolume[n] - sellVolume[n]
```

The result is displayed as a histogram in a subchart. The height of each bar represents the magnitude of the imbalance, and the color indicates direction.

## Chart Type

| Property    | Value                               |
| ----------- | ----------------------------------- |
| Type        | Subchart                            |
| Position    | Below main chart                    |
| Data source | Trade-level buy/sell classification |

## Settings

| Parameter          | Description                           | Default   |
| ------------------ | ------------------------------------- | --------- |
| positiveColor      | Color for bars where buyers dominate  | `#22c55e` |
| negativeColor      | Color for bars where sellers dominate | `#ef4444` |
| displayMode        | Rendering style                       | `columns` |
| highlightAnomalies | Flag statistical outliers             | `false`   |
| anomalyThreshold   | Standard deviation multiplier         | `2.5`     |
| anomalyPeriod      | Lookback period for anomaly stats     | `30`      |
| gradientIntensity  | Fill gradient strength (0-1)          | `0`       |

### Display Modes

| Mode      | Description                                               |
| --------- | --------------------------------------------------------- |
| `columns` | Histogram bars (default). Best for quick visual scanning. |
| `line`    | Continuous line connecting delta values.                  |
| `candles` | OHLC-style representation of delta.                       |

## Interpretation

### Spike Analysis

Large delta spikes indicate a sudden imbalance between buyers and sellers. These often appear at:

* **Support/resistance levels** — absorption or breakout
* **News events** — rapid positioning
* **Exhaustion points** — final push before reversal

<Tip>
  Large delta spikes often mark exhaustion points, especially at support and resistance levels. A massive positive delta bar at resistance that fails to push price higher suggests buyers are being absorbed.
</Tip>

### Delta vs. Price Movement

| Delta          | Price            | Interpretation                     |
| -------------- | ---------------- | ---------------------------------- |
| Large positive | Price rises      | Confirmed buying pressure          |
| Large positive | Price flat/drops | Buying absorbed by passive sellers |
| Large negative | Price drops      | Confirmed selling pressure         |
| Large negative | Price flat/rises | Selling absorbed by passive buyers |

### Anomaly Detection

When enabled, anomaly highlighting marks bars where delta exceeds the rolling average by more than `anomalyThreshold` standard deviations. These bars are rendered with distinct styling to draw attention.

<Note>
  Delta Volume shows the per-bar picture. For the cumulative trend, use CVD. The two are complementary — Delta for timing, CVD for trend.
</Note>

## Practical Examples

* **Breakout confirmation**: Price breaks resistance with a large positive delta bar — real demand behind the move.
* **Absorption**: Repeatedly large negative delta bars at support, but price holds — passive buyers absorbing the selling.
* **Climactic volume**: Extreme delta spike after an extended trend often signals exhaustion and potential reversal.
