Angular ChartsFinancial Charts - Volume Profile

Version 14.3.0

A Volume Profile shows the volume traded at each price level as horizontal bars against the price axis. It can be shown within a Financial Chart, or on its own as a Volume Profile Chart.

app.component.ts

import { Component } from "@angular/core";
import { AgFinancialCharts } from "ag-charts-angular";
import {
  AgFinancialChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getData, getVolumeProfile } from "./data";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgFinancialCharts],
  template: `<ag-financial-charts
        [options]="options"
    ></ag-financial-charts>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getData(),
      title: { text: "Acme Inc." },
      volumeProfile: {
        data: getVolumeProfile(),
        upKey: "upVolume",
        downKey: "downVolume",
      },
    };
  }
}

Data Copy Link

Volume Profile data has one row per price level, holding the price and the volume bought and sold at that price:

{
    data: [
        { price: 135, upVolume: 3873690, downVolume: 3499965 },
        { price: 137.5, upVolume: 15861342, downVolume: 13138794 },
        { price: 140, upVolume: 19126307, downVolume: 25942209 },
    ],
    priceKey: 'price', // default
    upKey: 'upVolume',
    downKey: 'downVolume',
}

Financial Chart Copy Link

Set volumeProfile on a Financial Chart to show a Volume Profile alongside the price data, as in the example at the top of this page. It takes its own data, separate from the chart's data.

{
    data: prices,
    volumeProfile: {
        data: profile,
        upKey: 'upVolume',
        downKey: 'downVolume',
    },
}

Hovering the chart shows the price level under the pointer in the status bar, after the price data values: its price range, up volume, down volume and total volume.

Volume Profile Chart Copy Link

Use a Volume Profile Chart to show a Volume Profile on its own, against a price axis.

app.component.ts

import { Component } from "@angular/core";
import { AgVolumeProfileChart } from "ag-charts-angular";
import {
  AgVolumeProfileChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getVolumeProfile } from "./data";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgVolumeProfileChart],
  template: `<ag-volume-profile-chart
        [options]="options"
    ></ag-volume-profile-chart>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getVolumeProfile(),
      title: { text: "Acme Inc." },
      upKey: "upVolume",
      downKey: "downVolume",
    };
  }
}

@Component({
    selector: 'app-root',
    standalone: true,
    imports: [AgVolumeProfileChart],
    template: `<ag-volume-profile-chart [options]="options"></ag-volume-profile-chart>`,
})
export class AppComponent {
    public options: AgVolumeProfileChartOptions;
    constructor() {
        this.options = {
            data: getVolumeProfile(),
            upKey: 'upVolume',
            downKey: 'downVolume',
        };
    }
}

Hovering a price level shows a tooltip.

Selecting Price Levels Copy Link

Set selection.enabled to let users select price levels. Selection is only available in a Volume Profile Chart.

app.component.ts

import { Component } from "@angular/core";
import { AgVolumeProfileChart } from "ag-charts-angular";
import {
  AgVolumeProfileChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getRegularVolumeProfile } from "./data";
import clone from "clone";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgVolumeProfileChart],
  template: `<div class="example-controls">
    <div class="controls-row">
        <span>Click Mode:</span>
        <div class="button-group" role="group" aria-label="Click Mode">
            <input type="radio" id="mode-single" name="click-mode" value="single" checked="" (change)="changeClickMode($event)">
            <label for="mode-single">Single</label>
            <input type="radio" id="mode-multiple" name="click-mode" value="multiple" (change)="changeClickMode($event)">
            <label for="mode-multiple">Multiple</label>
        </div>
    </div>
</div>
<ag-volume-profile-chart
        [options]="options"
    ></ag-volume-profile-chart>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getRegularVolumeProfile(),
      title: { text: "Acme Inc." },
      upKey: "upVolume",
      downKey: "downVolume",
      tickSize: 5,
      selection: { enabled: true, enableDrag: true },
    };
  }

  changeClickMode = (event: Event) => {
    const options = clone(this.options);

    options.selection = {
      ...options.selection,
      clickMode: (event.target as HTMLInputElement).value as
        "single" | "multiple",
    };

    this.options = options;
  };
}

{
    selection: {
        enabled: true,
        enableDrag: true,
    },
}

In this example:

Click a price level to select it, or drag across the chart to select every level the rectangle touches.
Use the Click Mode buttons to switch selection.clickMode between 'single' and 'multiple'.
See Selection for styling and the Selection API, and Events to respond to selection changes.

Tick Size Copy Link

Set tickSize to the price increment of the instrument to fix the height of each price level. Without it, each level is as high as the smallest gap between prices in the data.

app.component.ts

import { Component } from "@angular/core";
import { AgFinancialCharts } from "ag-charts-angular";
import {
  AgFinancialChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import {
  getData,
  getIrregularVolumeProfile,
  getRegularVolumeProfile,
} from "./data";
import clone from "clone";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgFinancialCharts],
  template: `<div class="example-controls">
    <div class="controls-row">
        <span>Data:</span>
        <div class="button-group" role="group" aria-label="Data">
            <input type="radio" id="data-regular" name="data" value="regular" checked="" (change)="changeData($event)">
            <label for="data-regular">Regular</label>
            <input type="radio" id="data-irregular" name="data" value="irregular" (change)="changeData($event)">
            <label for="data-irregular">Irregular</label>
        </div>
        <span class="gap-left">Tick Size:</span>
        <div class="button-group" role="group" aria-label="Tick Size">
            <input type="radio" id="tick-auto" name="tick-size" value="auto" checked="" (change)="changeTickSize($event)">
            <label for="tick-auto">Auto</label>
            <input type="radio" id="tick-1" name="tick-size" value="1" (change)="changeTickSize($event)">
            <label for="tick-1">1</label>
            <input type="radio" id="tick-2-5" name="tick-size" value="2.5" (change)="changeTickSize($event)">
            <label for="tick-2-5">2.5</label>
            <input type="radio" id="tick-5" name="tick-size" value="5" (change)="changeTickSize($event)">
            <label for="tick-5">5</label>
        </div>
    </div>
</div>
<ag-financial-charts
        [options]="options"
    ></ag-financial-charts>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getData(),
      title: { text: "Acme Inc." },
      volumeProfile: {
        data: getRegularVolumeProfile(),
        upKey: "upVolume",
        downKey: "downVolume",
      },
    };
  }

  changeData = (event: Event) => {
    const options = clone(this.options);

    const value = (event.target as HTMLInputElement).value;
    options.volumeProfile!.data =
      value === "irregular"
        ? getIrregularVolumeProfile()
        : getRegularVolumeProfile();

    this.options = options;
  };

  changeTickSize = (event: Event) => {
    const options = clone(this.options);

    const value = (event.target as HTMLInputElement).value;
    options.tickSize = value === "auto" ? undefined : Number(value);

    this.options = options;
  };
}

{
    tickSize: 2.5,
}

In this example:

Each price is rounded to the nearest multiple of tickSize, and the volumes of prices that round to the same level are added together.
Every level between the lowest and highest price is shown, so the levels stay evenly spaced. Levels with no data are left empty.
With the Irregular data and Tick Size Auto, the smallest gap between prices sets the level height, giving thin, uneven bars. Choose a Tick Size to group them into regular levels.
A larger tickSize merges more prices into each level, giving fewer, taller bars.

Total Segment Copy Link

Set totalSegment.enabled to show each price level's total volume in a column between the price axis and the bars.

app.component.ts

import { Component } from "@angular/core";
import { AgVolumeProfileChart } from "ag-charts-angular";
import {
  AgVolumeProfileChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getRegularVolumeProfile } from "./data";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgVolumeProfileChart],
  template: `<ag-volume-profile-chart
        [options]="options"
    ></ag-volume-profile-chart>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getRegularVolumeProfile(),
      title: { text: "Acme Inc." },
      upKey: "upVolume",
      downKey: "downVolume",
      tickSize: 5,
      totalSegment: { enabled: true },
    };
  }
}

In a Volume Profile Chart, totalSegment is a top-level option. In a Financial Chart, set it on volumeProfile:

{
    volumeProfile: {
        data: profile,
        upKey: 'upVolume',
        downKey: 'downVolume',
        totalSegment: {
            enabled: true,
        },
    },
}

Totals are abbreviated, such as 1.2K or 3.0M. Use label.formatter to change them.
The column is as wide as its widest label, but no narrower than minWidth. Set width to fix it instead.

Customisation Copy Link

Width and Placement Copy Link

In a Financial Chart, set widthRatio and placement on volumeProfile to change the size and side of the bars.

app.component.ts

import { Component } from "@angular/core";
import { AgFinancialCharts } from "ag-charts-angular";
import {
  AgFinancialChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getData, getVolumeProfile } from "./data";
import clone from "clone";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgFinancialCharts],
  template: `<div class="example-controls">
    <div class="controls-row">
        <span>Placement:</span>
        <div class="button-group" role="group" aria-label="Placement">
            <input type="radio" id="placement-left" name="placement" value="left" (change)="changePlacement($event)">
            <label for="placement-left">Left</label>
            <input type="radio" id="placement-right" name="placement" value="right" checked="" (change)="changePlacement($event)">
            <label for="placement-right">Right</label>

            <input type="radio" id="ratio-0-5" name="width-ratio" value="0.5" checked="" (change)="changeWidthRatio($event)">
            <label for="ratio-0-5">0.5</label>
            <input type="radio" id="ratio-0-75" name="width-ratio" value="0.75" (change)="changeWidthRatio($event)">
            <label for="ratio-0-75">0.75</label>
        </div>
    </div>
</div>
<ag-financial-charts
        [options]="options"
    ></ag-financial-charts>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getData(),
      title: { text: "Acme Inc." },
      volumeProfile: {
        data: getVolumeProfile(),
        upKey: "upVolume",
        downKey: "downVolume",
        placement: "right",
        widthRatio: 0.5,
      },
    };
  }

  changePlacement = (event: Event) => {
    const options = clone(this.options);

    options.volumeProfile!.placement = (event.target as HTMLInputElement)
      .value as "left" | "right";

    this.options = options;
  };

  changeWidthRatio = (event: Event) => {
    const options = clone(this.options);

    options.volumeProfile!.widthRatio = Number(
      (event.target as HTMLInputElement).value,
    );

    this.options = options;
  };
}

{
    volumeProfile: {
        data: profile,
        upKey: 'upVolume',
        downKey: 'downVolume',
        placement: 'left',
        widthRatio: 0.75,
    },
}

In this example:

widthRatio sets the length of the longest bar as a ratio of the series area width. It defaults to 0.5.
placement sets the edge the bars extend from, 'left' or 'right'. It defaults to 'right'.

Colours Copy Link

By default, the bars use the up and down fills of the theme palette.

Set up and down to style the bars of each direction with options such as fill, fillOpacity, stroke and strokeWidth. These take precedence over the theme palette.

app.component.ts

import { Component } from "@angular/core";
import { AgFinancialCharts } from "ag-charts-angular";
import {
  AgFinancialChartOptions,
  FinancialChartModule,
  ModuleRegistry,
} from "ag-charts-enterprise";
import { getData, getVolumeProfile } from "./data";

ModuleRegistry.registerModules([FinancialChartModule]);

@Component({
  selector: "my-app",
  standalone: true,
  imports: [AgFinancialCharts],
  template: `<ag-financial-charts
        [options]="options"
    ></ag-financial-charts>
`,
})
export class AppComponent {
  public options;

  constructor() {
    this.options = {
      data: getData(),
      title: { text: "Acme Inc." },
      volumeProfile: {
        data: getVolumeProfile(),
        upKey: "upVolume",
        downKey: "downVolume",
        up: { fill: "#F2C12E", stroke: "#B8901A" },
        down: { fill: "#2E6BF2", stroke: "#1A45A8" },
      },
    };
  }
}

{
    //...other volume profile options
    up: { fill: '#F2C12E', stroke: '#B8901A' },
    down: { fill: '#2E6BF2', stroke: '#1A45A8' },
}

In this example:

up and down colour the bars of the up and down volume.
A stroke is 1 pixel wide unless strokeWidth is set.

The status bar uses the up.fill and down.fill colours to display these values.
