What are the psychological biases that affect trading?

Psychological biases can significantly impact trading decisions. Common biases include overconfidence, where traders overestimate their knowledge and ability, leading to excessive risk-taking. Another is loss aversion, which causes individuals to prefer avoiding losses over acquiring equivalent gains, potentially resulting in poor decision-making. Confirmation bias also plays a role, as traders may favor information that supports their existing beliefs while ignoring contradictory data. Additionally, herd behavior can influence traders to follow the crowd, potentially leading to market bubbles or crashes. Understanding these biases is critical for developing a disciplined trading strategy and maintaining emotional control.
