eXorithm – Execute Algorithm: Embed Algorithm stock_ticker
Embed This Algorithm
This page will help you embed the algorithm stock_ticker on a page on your own website. Just configure the inputs, then click the generate button to get a snippet of code you can paste onto your site. You have two options.
- You can embed the entire form. Users will be able to enter their own arguments, and will need to press the run button
to execute the algorithm. - You can add only the output of the algorithm to your website. There will be no argument inputs or run button.
