What Is Trading Psychology?
I’ve been saying this for years: the market is the best school of self-discovery you’ll ever find.
That probably sounds strange coming from a trading coach. But after 20 years coaching traders, from hedge funds such as King Street Capital to retail traders in live sessions on X, I’ve seen the same thing play out thousands of times.
Trading psychology is the invisible force inside every account. And in my experience, it matters far more than most traders want to admit.
Key Takeaways
- In 15 years of data on day traders in Taiwan, fewer than 1% were able to earn reliable profits after fees (read the study)
- In a small 2025 study, traders who did a brief mindfulness exercise showed lower stress hormones and higher testosterone, a combination linked to better results in a trading task. The authors call these early findings (Psychoneuroendocrinology, 2025)
- Kristin Neff’s work on self-compassion suggests that people who treat themselves kindly after a failure are more motivated to try again (her research)
- In a small study on a London trading floor, traders’ morning testosterone went with better days, and their stress hormones rose with market volatility (Coates & Herbert, Cambridge, 2008)
What Is Trading Psychology?
Trading psychology isn’t just about controlling emotions. Emotion is part of how you make decisions in the first place (Coates & Herbert, Cambridge, 2008). A study of 17 traders found that their hormones moved with their profits and with market volatility. The researchers suggested this may shape how much risk feels acceptable.
Trading psychology is the study of the mental, emotional, and behavioral patterns that influence how you make decisions as a trader. It covers why you hold losing trades past your stop, why you take profits too early, and why you know the right move and still can’t make it.
Other work points the same way. In one brain-imaging study, people’s reward response lit up when they sold a stock at a gain, which may help explain why so many of us take winners too early and sit on losers.
What I take from all this: emotion isn’t separate from trading. It’s part of how you decide. Learning to work with it is what I see make the difference.
That distinction is the foundation of everything I teach. The goal isn’t to eliminate emotion from your trading. You can’t, and shouldn’t try. The goal is to feel the emotion without being driven by it.
That’s the core of what I teach on how to control your emotions while trading: not suppression, but learning to feel it without being run by it.
I teach what I call the Five Practices, a framework built over two decades of coaching traders and executives:
- Self-Responsibility – Owning your results without blame or excuse
- Empathy for Self and Others – Developing the compassion that creates clear seeing
- Emotional Non-Resistance – Learning to feel emotions without being hijacked by them
- The Hero’s Journey – Understanding that your trading path is a transformation, not just a transaction
- Mindfulness and Self-Awareness – Becoming the neutral observer of your own reactions
These aren’t soft concepts. They’re the architecture of sustainable trading performance.
Why Do Traders Fail Even with a Good Strategy?
Peer-reviewed research analyzing 66,465 brokerage accounts found that the most active traders earned 11.4% annually while the market returned 17.9% (Barber & Odean, UC Berkeley, 2000). A later study of day traders in Taiwan found that fewer than 1% earned reliable profits after fees. Most active traders struggle, and that shows up across several studies.
Sometimes it’s the strategy. Very often, in my experience, it’s the person executing it.
A good strategy executed by a fearful or shame-driven trader will often get inconsistent results. The trader’s nervous system, beliefs about money, and relationship with being imperfect all flow through every single decision.
Kahneman and Tversky’s Prospect Theory, published in Econometrica in 1979, established that humans feel losses roughly twice as intensely as equivalent gains (Kahneman & Tversky, 1979). That asymmetry shows up in many accounts that hold losers too long and cuts winners too short.
The strategy can be perfect. The trader can still blow it.
That gap between knowing what to do and actually doing it is what trading discipline is really about, and why adding more rules rarely fixes it.

What Is Force vs. Power in Trading?
Force vs. Power describes two fundamentally different modes of operating.
Force vs. Power is a framework from Dr. David Hawkins’ book Power vs. Force that describes these modes. Force is driven by “have to, must, should.” Power is self-sustaining and comes from genuine alignment with your process.
Force energy sounds like: “I have to make back what I lost today.” “I must be in the market right now.” “I should have seen that setup coming.” It feels like urgency and pressure. And it burns out.
Power is different. It’s grounded. It doesn’t need the market to validate it. It comes from trusting your actual edge and knowing that correct execution over time produces results.
I often ask the traders I coach to write two words on a Post-it above their screens: Power vs. Force. At the end of each trading session, as part of their trading psychology review, I have them ask: Did I trade from power or from force today?
That single question builds self-awareness and reveals the patterns driving a trader’s behavior, often becoming the turning point that improves trading discipline, decision-making, and ultimately, trading performance.
Force energy is also the engine behind overtrading: taking trades that aren’t there just to relieve the pressure of being flat.
Why Discipline Alone Won’t Fix Your Trading
Early studies on “ego depletion” suggested that self-control gets used up, especially under stress, though later attempts to repeat them found smaller effects (Baumeister et al., Florida State, 1998). What I see is simpler: under financial stress, a losing streak, a major drawdown, an account at risk, the rules are the first thing to go. Willpower tends to fail right when you need it most.
The biology goes even deeper. John Coates and Joe Herbert at the University of Cambridge studied traders on a London trading floor and found that morning testosterone went with better trading days, while stress hormone levels rose with the volatility of the market and of their results (Coates & Herbert, 2008). Coates later suggested that stress that goes on for weeks could leave traders overly cautious, even a kind of “learned helplessness” where they stop responding to opportunity. That’s his idea about long stretches of stress, not something the eight-day study measured.
In other words, a bad week doesn’t just hurt your P&L. It can leave your body wound up going into next week. Willpower alone may not be enough.
Old pinball machines had a “tilt” mechanism. If you shook the machine too hard, it shut down completely. Traders who are wound up from a hard stretch can be the same. They’re running on tilt. More rules don’t fix tilt. Understanding what’s driving it does.
One of the most common expressions of force energy is FOMO trading: the compulsion to chase a move because watching it happen without you feels like losing.
What Are the Biggest Psychological Traps for Traders?
In my coaching, the most expensive patterns cluster around three profiles. Most traders I work with recognize themselves in at least one.
The trader who holds losers but can’t hold winners. To hold a winning trade, you need to be comfortable receiving. You need to tolerate not knowing whether it’ll keep going. If vulnerability triggers fear, you’ll exit every winner before the run is complete.
Here’s what I’ve found after 20 years: if you deflect compliments in daily life, if praise makes you uncomfortable, you’re likely doing the same thing with market gains. The receiver is the same person.
The trader who trades from force is the one who can’t be wrong and can’t sit still. They override their plan, take marginal setups, and feel compelled to act even when nothing is there. Flat markets become intolerable. Waiting feels like losing. Being wrong feels unacceptable.
So they trade to relieve pressure, not to follow their edge.
This is what force trading looks like in real time. It’s driven by urgency, ego, and the need to regain control. Instead of executing a strategy, the trader reacts, chasing entries, pressing after losses, and abandoning discipline. Over time, that pattern erodes both trading performance and consistency.
The trader who knows their rules but can’t follow them is dealing with a trading psychology issue, not a strategy problem. More often than not, their self-worth is tied to being right. A losing trade can’t just be taken in stride, it feels like a personal attack. Until that attachment shifts, no upgrade in system or setup will improve trading discipline or consistency.
In coaching sessions, I’ll often ask: Can you receive a compliment, or do you deflect it? This isn’t about social behavior, it’s about your capacity to receive. The trader who exits winners too early to protect gains is often the same person who struggles to fully take in success. It’s the same nervous system pattern. The market reflects these behaviors clearly. The question is whether you’re willing to see them, and change them.
How Do You Actually Change Trading Psychology?
A small study published in 2025 found that traders who did a brief mindfulness exercise had lower stress hormones and higher testosterone than a comparison group (Psychoneuroendocrinology, 2025). That combination went with better results in a trading task. The authors call these early findings, and I’d hold them that way. One of the most useful tools I know is what author Rick Carson calls “simply notice” in his book Taming Your Gremlin.
Instead of fighting or suppressing a destructive impulse, you start by observing it.
“I notice I want to take a revenge trade right now.”
That’s it. Stated with curiosity, not judgment. The noticing creates a gap between impulse and action. That gap is small at first. With practice it grows. And in that gap is where your best trading decisions live.
It’s coaching wisdom, and that small study points the same way.
Carson calls the inner critic the Gremlin. In my coaching, I see four variants that cost traders the most:
- The Gremlin of Shame (“What does this loss say about me as a person?”)
- The Gremlin of Perfectionism (can’t cut a loss because cutting it means admitting they were wrong)
- The Gremlin of Scarcity (exits winners early because abundance feels unsafe)
- The Gremlin of Overconfidence (the boom before the inevitable bust)
The answer to all four is the same: simply notice, don’t fight. Judgment feeds the Gremlin. Curiosity starves it.
This noticing practice is also what separates developing traders from elite traders: not a different strategy, but a different relationship with their own reactions.
What Does Good Trading Psychology Look Like in Practice?
The traders I’ve seen make consistent progress share one quality: they approach their own psychology the way a good detective approaches a case. With curiosity, not judgment.
In my favorite childhood TV show, Detective Columbo appeared to be a bumbling fool. He asked disarming questions. He seemed harmless and confused. And then, with pure curiosity and no ego invested in being right, he solved the case every single time.
That is the operating mode of effective psychological work. Not “I messed up again, what is wrong with me.” Instead: “Interesting. I stayed in that trade 20% past my stop. What was happening for me in that moment?”
Judgment closes the learning loop. Curiosity opens it.
One technique that supports this is what management consulting calls appreciative inquiry. The premise: when you focus on what’s working, what isn’t working begins to quietly dissolve. Most traders can recite their weaknesses without pause. Ask them what they do consistently well, and it goes quiet.
That asymmetry is itself a problem worth solving.

Your Five Practices: A Framework for Trading Psychology
Based on 20 years of coaching, here’s how I recommend approaching trading psychology as an ongoing practice:
Practice 1: Self-Responsibility. The market isn’t happening to you. It’s happening for you. Every losing stretch is giving you data. The moment you stop being angry at yourself and start asking “what is this trade teaching me about myself?” something shifts.
Practice 2: Empathy for Self. Research by Dr. Kristin Neff at the University of Texas suggests that people who meet failure with self-compassion are more motivated to improve than those who meet it with self-criticism (Neff, UT Austin). In my experience, the traders who are hardest on themselves don’t trade better for it.
Practice 3: Emotional Non-Resistance. The goal isn’t to eliminate emotion from trading. Your emotional and physical reactions are part of how you make decisions. The goal is to feel the FOMO, the fear, the frustration, without being driven by it. That capacity is what separates emotionally reactive traders from those with true emotional discipline and consistent trading performance.
Practice 4: The Hero’s Journey. Every great trader’s story has a descent. Jack Schwager, who has interviewed the world’s greatest traders for the Market Wizards series, confirmed this directly on The Wall Street Coach Podcast. In his interviews he has shown that many of the world’s top traders experienced significant setbacks early in their careers. Losses, mistakes, and periods of struggle aren’t signs of failure, they’re often the process through which traders develop discipline, risk management, and long-term trading performance. The descent isn’t disqualification. It’s part of the path.
Practice 5: Mindfulness and Self-Awareness. A small 2025 study offers early support: after a brief mindfulness exercise, traders’ hormone levels shifted in a direction that went with better results in a trading task. For traders, this means journaling with psychological depth, tracking emotional state before each session, and developing their own neutral observer within themselves.
For traders putting Practice 5 into action, a structured end-of-session review is where trading discipline compounds over time.

Frequently Asked Questions
What is trading psychology?
Trading psychology is the study of the mental, emotional, and behavioral patterns that influence trading decisions. It covers how traders respond to losses, manage risk, and work through unconscious patterns (like shame, perfectionism, or scarcity beliefs) that undermine their edge even when their strategy is sound.
Why do traders fail even with a good strategy?
Most active traders struggle. In a study of day traders in Taiwan, fewer than 1% earned reliable profits after fees (read the study). Some of that is strategy. In my coaching, a lot of it is execution: stress that makes it hard to think clearly, losses that hurt about twice as much as gains feel good, and old patterns that technical knowledge alone doesn’t touch.
Can trading psychology actually be trained?
Yes. In a small 2025 study, traders who did a brief mindfulness exercise showed lower stress hormones and higher testosterone, which went with better results in a trading task (read the study). The authors call it early evidence. In my coaching, I’ve watched traders change with consistent practice. This isn’t a fixed trait. It’s a trainable skill.
What is the Power vs. Force concept in trading?
From Dr. David Hawkins’ work: Force is driven by “have to, must, should” energy. It depletes and collapses under pressure. Power is self-sustaining and comes from alignment with your actual process and edge. The daily question: “Did I trade from power or force today?”
