Psychological mistakes of traders that lead to losses

In 2025, psychological errors remain one of the main causes of losses in the Forex, stock, and cryptocurrency markets. Fear, greed, impulsive decisions, and disregard for risk management directly impact traders' profitability. According to TradingEconomics (USA, September 2025), approximately 70% of beginner traders lose capital due to psychological factors.

Context and significance

Trading isn't just about technical analysis; it's also about managing your emotions. Even experienced traders are susceptible to stress and market influences. In 2025, the high volatility of EUR/USD (1.08–1.12), BTC (~$65,000), and the NASDAQ and S&P 500 stock indices makes psychological control critical.

The main psychological mistakes of traders

Fear of loss

Panic closing of positions during a short-term drawdown.
Example: a trader closed a short position on USD/RUB during a short-term rise in the exchange rate, missing the subsequent correction.

Greed

Increasing rates without analysis and exceeding acceptable risk.
Example: A cryptocurrency trader increased a position by 50% after a small profit, only to lose a significant portion of his capital when BTC pulled back.

Chasing losses

Trying to compensate for past losses leads to emotional decisions.
Example: A trader who lost on the S&P 500 took a risky position to "win back" the losses, which only made them worse.

Impulsive decisions due to news

Reaction to macroeconomic data without trend analysis.
Example: sudden selling of EUR/USD after the US CPI report without taking into account the weekly trend.

Too much risk per trade

Violation of risk management principles leads to significant losses.
Example: A trader risked 10% of his capital on one trade instead of the recommended 2%, losing most of his deposit.

Burnout and fatigue

Long trading sessions without breaks reduce concentration.
Example: An error in opening a position on NASDAQ after 12 hours of trading resulted in a loss.
