As we continue to integrate NYMEX business operations to CME Group, we are moving toward providing a single Web site containing valuable information on all of our products and services.
While much of the nymex.com content from the About the Exchange, News, Education, Visitors, Resources and Shareholder Relations sections of the site already redirects to content on cmegroup.com, more recently, we made the Energy Products and Metals Products available as well.
We have prepared a document of frequently asked questions outlining potential answers to common inquiries. Review that document by clicking here.
In the coming days, you will notice additional changes to nymex.com:

In the coming weeks, CME Group will be replacing the current NYMEX settlement files with the CME Group standard text settlement format as well as a CSV format for Energy and Metals products only. To prepare for the changes, you can visit www.cmegroup.com/market-data/settlements to view sample files and file layouts for these new reports.
Please remember to bookmark the pages you are redirected to on cmegroup.com to easily find the information upon your return visit.
Please send us comments and suggestions via the link at the top right corner of each web page on cmegroup.com.
If you require navigation assistance for the Web site, please send an email to: info@cmegroup.com.
