BBW

Bollinger Bands Width

Data Format

The indicator requires main overlay in the following format:

js
[<timestamp>, <open>, <high>, <low>, <close>, <volume>]

How to use

Add a new object with type BBW to scripts array of a selected pane:

js
// Pane object:
{
    overlays: [], // Non-generated overlays
    scripts: [{
        type: 'BBW',
        props: {}, // Script props
        settings: {} // Script settings
    }]
}

TIP

If you don't see the overlay, try to call chart.se.uploadAndExec(). This will upload the data to the script engine and execute all scripts.
