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.

  1. 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.
  2. You can add only the output of the algorithm to your website. There will be no argument inputs or run button.
