Symptoms of illusion of control in trading

The Illusion of Control is a pervasive and dangerous cognitive bias in trading. It is defined as the mistaken belief that a trader can influence or control market outcomes that are, in reality, determined by chance or vast external forces. This illusion stems from the feeling of agency a trader gets from their actions—analyzing charts, placing orders, and choosing assets—which makes them feel they are shaping the market’s future, rather than simply managing their participation in it.

Why the Illusion Feels Real

This bias is particularly strong in trading because the environment is filled with “skill cues,” which are features that mimic skill-based tasks even in a chance-driven setting. These cues include:

• Choice: The freedom to choose which stock or currency to trade.

• Involvement: The time and effort spent researching, analyzing charts, and monitoring positions.

• Familiarity: Recognizing patterns in price data (even if they are random, a phenomenon known as apophenia).

• Reinforcement: A successful trade reinforces the belief that skill, not luck, caused the outcome, creating a dangerous feedback loop.

The Consequences of This Bias

Believing you can control the uncontrollable leads directly to poor trading habits and significant losses. The primary consequences are:

• Overtrading: A trader believes that more activity equals more control, leading to high-frequency trades that rack up transaction costs.

• Excessive Leverage: False confidence encourages traders to use larger positions than are safe, dramatically amplifying the impact of losses.

• Poor Risk Management: The trader may widen stop losses or ignore tail risks, believing their “skill” can manage any outcome.

• Attribution Bias: The trader attributes all wins to personal skill but blames all losses on external “bad luck,” which prevents them from learning from their mistakes.

Research on professional traders (Fenton-O’Creevy et al., 2003) confirmed that individuals who scored higher on the illusion of control performed worse, had poorer risk management, and generated lower profits.

How to Overcome the Illusion of Control

The key to overcoming this bias is to shift your focus from controlling market outcomes (which is impossible) to controlling your own actions and risk (which is possible).

1. Use Rule-Based Trading: Adhere to a strict trading plan with predefined, objective rules for entry, exit, and stop-losses.

2. Journal Your Trades: Document your trades and, more importantly, your emotional state. This helps you recognize emotional triggers and impulsive decisions.

3. Focus on Data: Rely on data-driven backtesting and probabilities rather than “gut feelings” or short-term winning streaks.

4. Master Risk Management: Accept that you cannot control the market. The only true control you have lies in your position sizing, your diversification, and your discipline to follow your own rules.
