Processing CFTC Commitments of Traders Data for Market Analysis
Summary
The article explains how to build a MetaTrader indicator and reusable data interface for analyzing Commitments of Traders reports from Commission-provided CSV files. It distinguishes Legacy, Supplemental Commodity Index, and Disaggregated reports, describing the trader groups each contains. The Disaggregated report separates physical commodity businesses, swap dealers, managed money, and other reportable traders, while the Supplemental report provides a distinct index-trader category.
The proposed tool selects a report, trader group, and measure, then reads records for the current instrument. Available measures include net positions, net positions as a share of open interest, a Williams-style index, and open interest. The data can be plotted or accessed by other indicators, scripts, and expert advisors. The article also outlines record storage and instrument mapping. It is primarily a data-processing tutorial: it does not test a COT-based trading rule or establish that any trader category predicts prices. Its usefulness therefore depends on correct symbol matching, report interpretation, and separate validation of any strategy built from the data.
Key ideas
- Legacy, Supplemental, and Disaggregated COT reports classify futures market participants differently.
- COT data can be organized by instrument, trader group, reporting date, and selected position measure.
- Net positions, their share of open interest, a Williams-style index, and open interest are example outputs.
- A shared data interface can make report records available to indicators, scripts, and expert advisors.
- The tutorial explains access and processing rather than demonstrating predictive performance for a trading strategy.
