Hosting Library Cross Origin - SpartaCommodities/Trading_view_wiki GitHub Wiki

If you need to host the library files on a separate origin (domain) to the page containing the chart then please ensure that the library_path widget constructor parameter is configured as follows:

  • The library_path value should start with either http:// or https://, followed by the url to the folder containing the charting library's static files.
    • example: library_path: 'https://example.com/charting_library/'
  • library_path should end with a trailing forward slash.

Example: Loading the standalone version from separate origin

If you hosted the library files within a folder named charting_library on the example.com domain then you would configure the library as follows.

Loading the standalone script

Place the following script tag within the <head> of the page.

<script
    type="text/javascript"
    src="https://example.com/charting_library/charting_library.standalone.js"
></script>

Specifying the library_path parameter

When evoking the widget constructor, ensure that the library_path value starts with http as described above.

var widget = (window.tvWidget = new TradingView.widget({
    library_path: 'https://example.com/charting_library/',

    symbol: 'A',
    interval: '1D',
    container: 'tv_chart_container',
    datafeed: new Datafeeds.UDFCompatibleDatafeed(
        'https://demo_feed.tradingview.com'
    ),
}));

Server setup

Make sure that the server hosting the library files is configured to allow cross-origin requests from the origin of the page containing the chart element. Please see this MDN article for more information: Access-Control-Allow-Origin

Demo Charts and Study Templates Storage Server

Please note that the demo charts and study template storage server (http://saveload.tradingview.com) isn't compatible with requests from any origin except localhost and tradingview.com. Attempting to use this server from any other origin will still result in a CORS error.

Please see Saving and Loading Charts for an overview on how to setup your own storage server.
