Reach out your school's network admin and request to whitelist the following domain:

This will ensure that our data provider can get through to the webpage, so that the website can function properly.

Students encountering problems should try logging out and immediately logging back in to ensure that there is a fresh connection
with our servers.

Stale connections can often lead to problems.

Make sure that in the browser for each device being used (laptop, iPad, etc.) that cookies are fully enabled. We use cookies to establish secure sessions with our servers, so it is essential that they be accepted.

If all else fails, students can still place trades using the old trading platform. Navigate to the Enter Stock Trade page and click the link that reads ‘Switch to Old Version’ in the top right corner of the trade page. This will transfer them to our legacy system— less functionality is available but the trades should go through without issue.
