What does hindsight error involve?

Hindsight error refers to the tendency to believe that past events were predictable after they have already happened. This cognitive bias leads individuals to assume that they could have foreseen outcomes simply because they now possess knowledge of what occurred. In the context of trading and market analysis, this can lead to an overestimation of forecasting skills, as one may look back on a trading decision and feel confident that the outcome was obvious, despite the uncertainty that existed at the time the decision was made.

Recognizing hindsight error is crucial for traders because it highlights the difference between the clarity of outcomes viewed retrospectively and the uncertainty experienced in real-time decision-making processes. Understanding this concept can help market technicians avoid overconfidence in their ability to predict future market movements based solely on historical events.
