Report formats

Commitments of Traders (COT) Report

Weekly publication by the U.S. Commodity Futures Trading Commission (CFTC) showing futures market positioning by trader category. Released every Friday at 3:30 PM Eastern Time.

Futures Only

The Futures Only version of a COT report counts futures contracts only, without options. The Legacy report, the original CFTC COT format (Non-Commercial, Commercial, Non-Reportable), is shown here in its Futures Only version by default (COT Premium members can switch to Futures & Options Combined); the CFTC also publishes every report as Futures & Options Combined. The COT report itself dates to 1962; downloadable historical data on cftc.gov begins in 1986.

Trader categories

Non-Commercial

Large speculative traders — primarily hedge funds, CTAs and proprietary trading firms — that hold reportable positions but do not use the futures market for commercial hedging. Used as the speculative-sentiment proxy in the Legacy COT format.

Commercial

Hedgers — entities that use the futures market primarily to offset price risk in their underlying business (e.g. an oil producer selling futures, an airline buying futures). They usually trade against the trend — selling into strength and buying into weakness.

Non-Reportable

Traders whose position size is below the CFTC reporting threshold. Effectively retail and small institutional positioning. Often interpreted as a contrarian sentiment indicator at extremes.

Index Traders

Supplemental COT category specifically for entities whose positions are driven by tracking a major commodity index (e.g. S&P GSCI, Bloomberg Commodity Index). Includes index funds, ETFs and swap dealers hedging index-linked swap exposure.

Dealer/Intermediary

TFF COT category for large institutional market-makers in financial futures — typically the dealing desks of major banks and broker-dealers.

Asset Manager/Institutional

TFF COT category for pension funds, endowments, insurance companies and mutual funds. Holds longer-term positions for asset allocation rather than short-term speculation.

Leveraged Funds

TFF COT category for hedge funds, CTAs and other speculative money managers that take directional positions on financial markets. The financial-futures equivalent of Managed Money.

Positioning metrics

Open Interest

Total number of futures contracts opened and not yet closed, expired or delivered. Measures market participation. Rising open interest with rising price typically confirms an uptrend.

Net Position

Long contracts minus Short contracts for a given trader category. Positive means net long (bullish exposure); negative means net short (bearish exposure).

Long Position

A bet that the underlying market will rise. In the COT report, each trader category's long total is the sum of contracts held that profit when the price goes up.

Short Position

A bet that the underlying market will fall. In the COT report, each trader category's short total is the sum of contracts held that profit when the price goes down.

% of Open Interest

A trader category's net or gross position divided by the total Open Interest of the market, expressed as a percentage. Normalizes positions across markets of different sizes — a 100K Net Position means very different things in a deep-liquidity SOFR contract versus a thinly-traded soft commodity.

Concentration Ratio

The percentage of total Open Interest held by the four or eight largest traders in a market. Published in the CFTC's full-format COT reports. High concentration (>40% in the top 4) signals the market is dominated by a few big players — moves can be sharp when one of them rotates.

Net Change

The week-over-week difference in a trader category's Net Position. Positive Net Change means the category bought more / covered shorts during the reporting week; negative means they sold or shorted into the close. The most-watched single metric on every COT release.

Release cycle

As-of Tuesday

The COT Report always reflects open positions at the close of business on the Tuesday of the reporting week. The Tuesday close is the snapshot date — published three days later on the Friday of the same week.

Reporting Lag

The three-day gap between the Tuesday snapshot and the Friday publication. The CFTC uses this window to aggregate, validate and anonymize the data. Every COT report you read is exactly three business days old by design.

Release Time

CFTC publishes the weekly COT report every Friday at 3:30 PM Eastern Time. When a US federal holiday falls on the Wednesday, Thursday or Friday of that week (e.g. Veterans Day, Thanksgiving, Juneteenth, Independence Day observed, Christmas), the release moves to the following Monday at the same 3:30 PM ET slot.

Analysis & signals

COT Index

A normalized score (0–100) showing where a trader category's current Net Position sits relative to its rolling historical range. 0 = most short ever in the lookback window, 100 = most long ever. Used to spot extreme positioning. Common windows: 26, 52, 156 weeks.

Percentile Rank

The percentage of historical readings that the current value exceeds. A Net Position at the 95th percentile means it's higher than 95% of readings over the lookback period — historically extreme, often a contrarian signal.

Extreme Reading

An informal label for a positioning value at the very edge of its historical range — typically 0–5 (extreme short) or 95–100 (extreme long) on the COT Index. Markets often turn at these extremes because the dominant side has run out of new buyers / sellers.

Z-Score

Number of standard deviations the current Net Position is from its rolling mean. Z = +2 means current is 2σ above the average — a 1-in-40 reading historically. An alternative to COT Index for measuring positioning extremity, more sensitive to volatility shifts.

Divergence

When price action and trader positioning move in opposite directions. Example: price makes a new high but Non-Commercial Net Position shrinks. Often interpreted as a leading signal that the trend is losing institutional commitment.

Contract mechanics

Contract Month

The calendar month in which a futures contract expires. The CFTC aggregates positions across all listed contract months of a market, so the COT Net Position represents the entire futures complex, not just the front month.

Notional Value

The dollar value of one futures contract — calculated as the contract multiplier times the current price. A WTI Crude futures contract at $80/bbl has a notional of $80,000 (1,000 barrels × $80). Useful for sizing comparisons across markets.

Settlement Price

The official end-of-day reference price for a futures contract, set by the exchange. Used to mark-to-market open positions, calculate margin and trigger contract-related events. The Tuesday settlement is what the COT 'as-of' snapshot anchors to.

What does COT stand for?

COT stands for Commitments of Traders, the weekly CFTC report that shows how futures positions are split between trader categories. It is published every Friday at 3:30 PM ET and reflects positions as of Tuesday’s close. When a US federal holiday falls on the Wednesday, Thursday or Friday of that week, the release moves to the next business day, usually Monday; a Monday holiday does not delay it (see the CFTC release schedule).

What is the difference between Commercial and Non-Commercial traders?

Commercial traders use futures to hedge business risk, while Non-Commercial traders are large speculators trading to profit from price moves. Commercials are producers, merchants and users of the underlying asset and often position against the trend; Non-Commercials are mostly hedge funds and CTAs. Both are Legacy report categories, and the Non-Commercial net position is the classic gauge of speculative sentiment.

What is the Net Position in the COT report?

The Net Position in the COT report is a trader category’s long contracts minus its short contracts. A positive Net Position means the group is net long, a negative one that it is net short. The change from one week to the next is called Net Change, and the COT Index ranks the current Net Position within its historical range.

What is a high or low COT Index reading?

A COT Index reading of 95–100 is extremely high: on the index’s 0–100 scale, the category’s Net Position is close to its most net-long level of the lookback window. A reading of 0–5 is extremely low, close to its most net-short level. On COT-Reports.com the COT Index is free; the 26- and 52-week lookbacks are open to everyone, the 3- and 5-year ones need a free account.

Which trader categories can I read for free on COT-Reports.com?

The Legacy categories, Non-Commercial, Commercial and Non-Reportable, are free on COT-Reports.com for every CFTC market. Without an account the Simplified and Detailed reports show up to 6 months of history; a free account opens up to 10 years, and Charts and the Weekly Summary are open to everyone. The Disaggregated, TFF and Supplemental categories, such as Managed Money, Leveraged Funds and Index Traders, are part of COT-Reports Premium.
