Indicators

Each indicator can be added with the method Controller.addIndicator to an existing Controller. It returns the new instance of Indicator.

const indicator = controller.addIndicator('TEMA');
Copy

Similar to data loaders, the identifiers used to create indicators may also contain parameters. For example, "SMA(14)" will yield a simple moving average of the last 14 values. These parameters may be modified after the initial creation. For example, the following two examples result in the same indicator:

// specify parameter at creation
const indicator = controller.addIndicator('SMA(14)');

// specify parameter after creation
const indicator = controller.addIndicator('SMA');
indicator.set('period', 14);
Copy

To see which indicators are available, import plugins from your bundle, and filter for clazzType indicator.

    import { plugins } from '@stock3/charting-bundle-chartbreaker';

    const indicators = Object.entries(plugins).filter(([pluginName, clazzDescriptor]) => clazzDescriptor.clazzType === 'indicator');
    // [indicatorName, clazzDescriptor][]
Copy
