Understand how large institutional players — the whales — are positioned in the market. Establish a longer-term bias and align it with your order-flow model for high-conviction trades.
Part 1 · Foundations
How the COT Report Works
The Commitment of Traders report is published weekly by the CFTC and reveals how different categories of market participants are positioned across futures markets. One group — and only one — tells you what the whales are actually doing.
DATA SOURCE & SETUP
PLATFORM
Where to Access
Use a platform like Trading Stairs or any reliable COT data provider. Navigate to the Indices section to find the equity index futures data you need.
REPORT TYPE
Use the Legacy Report
Always select the Legacy report format. It provides a clear, historically consistent breakdown of participant categories — the cleanest view for directional analysis.
FREQUENCY
Weekly Release
Data is released every Friday reflecting positions as of the prior Tuesday. The weekly change column is what drives your directional read — check it every week without exception.

THE ONLY GROUP THAT MATTERS
Non-Commercials are the speculators — asset managers and leveraged money whose sole motivation is price movement. Commercials hedge existing business exposure and are therefore counter-trend by design. Non-Reportables are retail. Strip both away and you are left with the institutional directional bet.
Part 1 · Data Structure
Reading the Numbers
For each index futures market, the COT report gives you two distinct lenses: the long-term structural position (open interest) and the short-term weekly shift (changes). Each tells a different part of the story.
LONG-TERM LENS · OPEN INTEREST
◈
Long positions: Total number of contracts held net long by Non-Commercials across all active expirations.
◈
Short positions: Total contracts held net short. A massive excess here signals a structurally bearish institutional stance.
◈
Net ratio: The overall balance of longs to shorts. This is your macro bias — the direction the big money is structurally leaning across weeks and months.
SHORT-TERM LENS · WEEKLY CHANGES
◈
Change in longs: How many new long contracts were added (or removed) relative to the prior week. Positive = buying pressure. Negative = longs closing.
◈
Change in shorts: How many new short contracts were added (or removed). This is the most important input — it shows who is stepping on the gas right now.
◈
The skew: The difference between new longs and new shorts. A large skew in one direction reveals where institutional momentum is flowing this week.
MOST IMPORTANT INPUT
The weekly Changes column is where the actionable signal lives. Open interest tells you the structural lean; the weekly change tells you what is happening right now — who is adding conviction, and in which direction. Both matter, but the change drives the immediate bias.
Part 2 · Practical Analysis
The Analysis Matrix
Applying the COT report is a three-step process. Each step builds on the last — from identifying the directional skew, to confirming it across multiple indices, to synchronising it with price and volume for execution.
01
Analyse the Net Skew and Its Strength
Compare newly added longs with newly added shorts in the weekly changes column. The difference between the two is the "skew" — the directional force this week.
02
Build a Matrix Across the Indices
Run the same skew analysis for S&P 500, Nasdaq, and Dow Jones (optionally Russell 2000) in parallel. Confluence across multiple indices dramatically increases the signal quality.
03
Synchronise with Price and Volume
This is the critical execution step. Locate the price level where the heavy distribution took place and align it with your Volume Profile structure — specifically VAH or VAL levels.
Step 01 · Skew Analysis
Measuring Directional Skew
The skew is the net difference between newly added long and short contracts in a single week. Its size tells you how aggressively institutions are tilting in one direction — and whether that tilt is meaningful enough to trade.
EXAMPLE · BEARISH SKEW
Short Bias Scenario
+1,000 longs against +5,000 shorts. The net short skew is 4,000 contracts — a strong, immediate institutional tilt toward selling. This constitutes a bearish signal.
AMPLIFIED SKEW · CLOSING POSITIONS
Closing Longs Amplifies the Signal
When 2,000 long contracts are closed and 5,700 shorts are simultaneously opened, the effective net short skew becomes 7,700 contracts — far more significant than shorts alone.
RULE OF THUMB · WHAT COUNTS AS "STRONG"
A directional skew of roughly 30% or more relative to total weekly positioning is considered significant. Below that threshold, the signal is noise. Above it, you have an institutional lean worth incorporating into your bias — especially when multiple indices confirm.

Step 02 · Cross-Index Matrix
The Index Matrix
A skew in a single index is a data point. A skew confirmed across S&P 500, Nasdaq, and Dow Jones simultaneously is a signal. When the majority of major indices show a strong short skew in the same week, the overall market is very likely to move lower.

READING THE MATRIX
In the example above, three out of four indices show a strong short skew. The Dow is mixed. The overall verdict: bearish bias is confirmed. When the majority aligns, you have institutional consensus — not just one market's noise. This is the directional conviction you need before applying execution-level tools.
CONFLUENCE CONFIRMED · BEARISH READ
✓
Majority of indices show net short skew above 30% threshold
✓
Both S&P 500 and Nasdaq (the two most correlated) confirm
✓
Russell 2000 adds further confirmation — small-caps also positioned short
→
Overall market bias: Bearish. Align all trade ideas accordingly.
MIXED SIGNAL · PROCEED WITH CAUTION
?
Indices split — S&P short but Nasdaq neutral, Dow long
?
No clear majority alignment across the index universe
?
Signal is inconclusive — institutional positioning is itself uncertain
→
No strong COT bias this week. Reduce position sizing. Rely more heavily on intraday structure.
Step 03 · Price Synchronisation
Sync with Price & Volume
This is the critical step before execution. The COT tells you the directional bias — but only by locating where the institutional distribution actually took place in price space can you turn that bias into a precise trade.
KEY CONCEPT
Locate the Distribution Level
Identify the exact price level where heavy short distribution occurred. If this aligns with a VAH — the upper boundary of a Volume Profile's fair value zone — that supply zone gains enormous structural significance.
LONG-TERM VS SHORT-TERM
Interpreting Temporary Rallies
When the COT shows a long-term short position but the weekly change shows net long additions, you are most likely seeing temporary profit-taking inside a broader downtrend — not a genuine reversal.
THE CRITICAL CONNECTION
A massive short distribution that occurred exactly at a Value Area High is not a coincidence — it is the same institutional supply that the Volume Profile recorded. The COT gives you the "why" (institutional selling), the Volume Profile gives you the "where" (the exact price level). Together they create a high-conviction supply zone.
LONG-TERM VS SHORT-TERM DISTINCTION
SCENARIO A
Short Bias + More Shorts Added
→
Institutional conviction is increasing. Bears are adding to their position. Strongest possible bearish read.
SCENARIO B
Short Bias + Longs Added
→
Likely profit-taking within a downtrend. Interpret rallies as temporary — do not flip to bullish bias.
SCENARIO C
Short Bias + Shorts Closed
→
Bears taking profits. Possible short-term bounce incoming but structural bias remains bearish until open interest shifts.

SUMMARY · HOW TO USE THE COT
The COT report is a weekly macro filter — not an entry signal. Use it to establish the directional bias at the start of each week. Then apply your Volume Profile and order-flow tools within that bias. When the COT, the VP distribution level, and your intraday order flow all point the same way, you have one of the highest-conviction trade setups available to a retail trader.
