Volume and open interest reports for CME Group futures and options contain monthly and weekly data available free of charge.
Please note: The Daily Volume and Open Interest Report is released at the end of each trading day and is a preliminary report. CME Group releases official data in the Daily Bulletin the following morning. Preliminary reports may be different from the final report. We have updated the field used to capture the product names in the Web Monthly Volume Reports to provide a more accurate picture of our products. This change is effective from 1st May 2018.
