# Volume Delta Methods (Chart)

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

Volume Delta Methods (Chart) plots order-flow metrics straight onto the price chart: volume delta and total volume as histograms, and cumulative volume delta as a line, area, baseline, or candles, with buy/sell volume in label tooltips. Divergences between delta polarity and price bars flag potential turns, while CVD tracks which side has controlled entire moves.

**Volume Delta Methods (Chart)** brings order flow onto the price chart itself, plotting the [net difference between buying and selling activity](https://www.luxalgo.com/library/concept/volume-delta/) and total volume as histograms, with buy/sell volume shown in the tooltips of the optional value and divergence labels. Layered on top, [cumulative volume delta](https://www.luxalgo.com/library/concept/cumulative-volume-delta/), drawn as a line, area, baseline, or candles, aggregates that pressure over time, showing which side has controlled an entire move rather than a single bar.

## How to Trade the Volume Delta Methods (Chart)?

- **Positive delta**: buying pressure leads the bar; **negative delta**: sellers dominate it.
- **Delta polarity against bar polarity**: when the two disagree, a divergence prints, an early clue for reversals, or for continuation hiding beneath the surface.
- **CVD direction and divergences**: sustained CVD trends reveal longer-horizon conviction, and price rising against a falling CVD deserves suspicion.
- **Numerical values**: optional labels for reading exact delta figures.

Two estimation modes drive the numbers: Intrabar Buying/Selling Pressure infers direction from where each lower-timeframe close lands within its bar's range, while Intrabar Polarity classifies by close versus open. A volume moving average and a CVD smoothing line are available for extra context.

## Volume Delta Methods (Chart) Settings

- **Calculation Method**: 'Intrabar Buying/Selling Pressure' or 'Intrabar Polarity'.
- **Lower Timeframe Precision** (default Auto): granularity of the intrabar estimate.
- **Presentation toggles**: Volume Delta, Cumulative Volume Delta, and Divergences on or off.
- **Advanced features**: Volume Moving Average and CVD Smoothing Line.
- Colors, display length, and height are adjustable per element.

## Frequently Asked Questions

### Which calculation method should I use?

Intrabar Buying/Selling Pressure credits volume to the side each lower-timeframe close leans toward within its range; Intrabar Polarity simply compares close against open. Both fall back to the change from the previous close when a bar is perfectly balanced, so try each and keep the one that matches your read of aggression.

### What pairs well with this tool?

[EquiVolume](https://www.luxalgo.com/library/indicator/equivolume/) scales bar width by traded volume, making activity part of the price bars themselves, a natural companion when delta and price are telling different stories.

### How can I access Volume Delta Methods (Chart)?

Access is free via the LuxAlgo Library, with the option to run it in Quant, our coding agent, directly from this page. You can also copy the source code from this page and run it anywhere Pine Script® runs.
