The Commitments of Traders (COT) reports provide a breakdown of each Tuesday’s open interest for market reports in which 20 or more traders hold positions equal to or above the reporting levels established by the CFTC.

Please see the official Release Schedule for a calendar of release dates.

Reports are available in both a short and long format. The short report shows open interest separately by reportable and nonreportable positions. For reportable positions, additional data is provided for commercial and non-commercial holdings, spreading, changes from the previous report, percents of open interest by category, and numbers of traders.

The long report, in addition to the information in the short report, groups the data by crop year, where appropriate, and shows the concentration of positions held by the largest four and eight traders.

Supplemental reports show aggregate futures and option positions of Noncommercial, Commercial, and Index Traders in 12 selected agricultural commodities.

Effective with this week’s Commitments of Traders report, the Commission staff has reclassified certain positions in the copper futures and options markets from the Noncommercial category to the Commercial category. Commission staff periodically evaluate these classifications and will change a classification in light of new or additional information.

These text-only files contain the most recent Futures-only and Futures-and-Options-Combined long form data in a comma delimited format for easy loading into a spreadsheet.
