# Supply Demand Profiles

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

Profiles traded volume across every price in a range you select, framing supply and demand zones alongside a full volume profile and a sentiment profile. Choose raw volume with one of five polarity methods, or volume delta with one of two intrabar methods, to split activity into buying and selling. A complete range-analysis station for volume-minded traders.

**Supply Demand Profiles** reads a user-selected range three ways at once. [Supply & demand zones](https://www.luxalgo.com/library/concept/supply-and-demand-zones/) appear as horizontal areas inside the range, a volume profile on the right details traded activity at every price, and a sentiment profile on the left splits that activity into bullish and bearish share. The profile marks the point of control, the [value area](https://www.luxalgo.com/library/concept/value-area/) with its high and low, and the profile extremes. And your choice of volume source and polarity method decides how activity is classed as up or down.

## How to Trade the Supply Demand Profiles?

- **Zones first**: the highlighted supply and demand areas mark thinly traded prices within the range, rows whose volume is below the threshold share of the point of control's volume, with supply above the POC and demand below it; treat them as reference points for anticipating reactions on a revisit.
- **POC and value area boundaries**: the point of control and the VAH/VAL lines identify the prices that carried the bulk of trade, prime levels to watch.
- **Sentiment check**: the left-hand profile reveals which side dominated at each price, a gauge of conviction behind a level.
- **Re-frame freely**: drag the range points on the chart, or set start and end times manually, to profile any swing or session.

## Supply Demand Profiles Settings

- **Volume Data Source**: seven options: 'volume' with one of five polarity methods (bar polarity, bar buying/selling pressure, intrabar polarity, intrabar buying/selling pressure, or heikin ashi bar polarity), or 'volume delta' with intrabar polarity or intrabar buying/selling pressure.
- **Lower Timeframe Precision**: applies when an 'Intrabar (LTF)' option is selected.
- **Value Area Volume %**: the percentage of total volume defining the value area.
- **Supply & Demand Threshold %**: rows whose volume is below this percentage of the point of control's volume are marked as supply zones (above the POC) or demand zones (below it).
- **Number of Rows & Placement / Profile Width %**: govern the profile's granularity, location, and width.
- Visibility and color options cover the zones, both profiles, value areas, price levels, and background fills.

## Frequently Asked Questions

### What separates 'volume' from 'volume delta' as a source?

'Volume' counts all recorded trades at each bar, while 'volume delta' keeps the net difference between buying and selling, showing who actually won the bar. If delta is your focus, [Volume Delta](https://www.luxalgo.com/library/indicator/volume-delta-methods-chart/) develops the idea into a dedicated chart.

### Why does the tool draw two profiles?

They answer different questions: the right-hand volume profile tallies trade at each price, while the left-hand sentiment profile shows who was in control there. Read together, they separate busy prices from genuinely one-sided ones.

### How do I access Supply Demand Profiles?

Free, via the LuxAlgo Library. This page also opens it in Quant, our coding agent, so you can test polarity methods over historical ranges. You can also copy the source code from this page and run it anywhere Pine Script® runs.
