What Real Futures Traders
Prove About Discipline

Why These Studies Are Different

Most studies on trading psychology use students trading in simulated environments. No real money, no real pressure, no real consequences. The three studies on this page are different. They examine professional futures traders – in real markets, with real money, under real pressure.

Finding 1: Discipline Is Measurable

Locke & Mann developed a quantitative measure for trading discipline. They demonstrated that discipline is not a vague concept but a measurable behavioral indicator. Traders with higher discipline scores achieved consistently better results.

Finding 2: Even Pros Struggle with Loss Aversion

Even experienced floor traders at the CBOT showed signs of loss aversion. They held losing positions longer than optimal and took profits faster than their strategy called for. This is the same disposition effect that Odean found in retail traders – only in professionals who had been in the markets for years.

Finding 3: Discipline Separates Winners from Losers

The decisive difference between profitable and unprofitable CBOT traders was not strategy, not market knowledge, and not experience. It was the ability to follow their own rules. Discipline was the strongest predictor of long-term success.

Joshua Coval and Tyler Shumway from the University of Michigan examined the intraday behavior of professional futures traders at the CBOT. Their 2005 study provided the scientific proof for revenge trading.

The setup: The researchers analyzed how traders' risk behavior changed throughout the day – depending on whether they had gains or losses in the morning.

The result: Traders who suffered losses in the morning took on significantly more risk in the afternoon. They increased their position sizes, traded more aggressively, and deviated from their normal patterns. Traders with morning gains traded more conservatively.

What this means: Revenge trading is not a myth and not a beginner's mistake. It is a scientifically proven behavioral pattern that occurs even in professional floor traders. Your brain switches to risk mode after losses – regardless of your experience.

Brad Barber and Terrance Odean analyzed the trading volume and performance of traders in several studies (2000, 2001). Their most famous finding: The most active traders achieve the worst returns.

The data: Barber & Odean divided traders into five groups – from least active to extremely active. The results were clear:

• The most active 20% of traders achieved the lowest net returns
• More trades led to higher transaction costs that ate into profits
• Overtrading correlated strongly with overconfidence (overconfidence bias)
• Male traders traded 45% more than female traders – and achieved worse results

The message: Trading more doesn't make you more profitable. On the contrary – overtrading is a reliable indicator of poor performance. Quality beats quantity. Always.

What This Means for Futures Traders

You might think: “These are US studies on US traders. What does this have to do with me?” The answer: Everything.

The markets you trade – ES, NQ, CL, GC – are the same markets examined in these studies. The Chicago Board of Trade, the CME – these are the exchanges where your futures are traded. The traders in these studies traded the same products as you.

And the neurobiological mechanisms – loss aversion, revenge trading, overtrading – are universal. They apply to traders in Chicago just as much as to traders anywhere in the world.

The three key findings for your trading:

• Discipline is measurable – and the strongest predictor of your success (Locke & Mann)
• Morning losses change your behavior – recognize the pattern before it costs you money (Coval & Shumway)
• Less trading = more earning – quality beats quantity, without exception (Barber & Odean)

FAQ – Futures Trader Studies

What Is the Most Important Finding from the CBOT Studies?

The most important finding is that discipline is the strongest measurable success factor in futures trading. Locke & Mann demonstrated that neither strategy nor experience correlate as strongly with long-term success as the ability to follow your own rules.

Does Revenge Trading Apply to Professional Traders Too?

Yes. The Coval & Shumway study proves exactly that. Even professional floor traders at the Chicago Board of Trade significantly increased their risk after morning losses. Revenge trading is not a beginner's problem – it is a neurological pattern that affects every trader, regardless of experience or knowledge.

Why Do Active Traders Achieve Worse Returns?

Barber & Odean identified three main reasons: First, higher transaction costs from more trades. Second, more emotional decisions instead of analytical ones. Third, overconfidence (overconfidence bias) that makes traders believe they can beat the market by trading more frequently. The data shows the opposite.
