1.3 Adding a UDI to a chart

You add a UDI to a chart – including any of the examples – by clicking on the indicators button in the chart toolbar, choosing Advanced / UDI, and then pasting in the Javascript code.

You can also store your UDI on a web server, and then paste in the URL of the file rather than its contents. Note: your server must be CORS-friendly; your server must set the CORS headers Access-Control-Allow-Origin and Access-Control-Allow-Credentials on its response so that the chart is allowed to make the cross-origin HTTP request.

If you want to share your UDI with other people while protecting how it does its calculation, you can use a code obfuscation service. Examples include javascript-obfuscator (free) and JScrambler (paid).
