Site Update Overview

OCC has completely redesigned and fully modernized its website. As a result, certain pages have changed. Information about key enhancements and updates to the site can be found below.


  • We've simplified the navigation and consolidated certain pages, grouping content in a way that will enhance your ability to find the information you want, fast.

  • A System Status indicator has been permanently added to all pages so that you can quickly learn about issues that may be affecting the site or the clearing system.

  • FIXML and DDS reference documents have been moved from the Membership area of the previous site to the Clearance and Settlement area of the new site.

  • Newsroom pages and other items published prior to 2014 have been removed from the site and archived. Contact us with any questions about accessing archived content. Note: Content archiving does not affect Information Memos, all of which will remain on the site for all years.
