01
Treating a pattern as a prediction
A pattern is a description of historical price behavior under stated rules. It does not guarantee a future outcome. Keep the observation, possible interpretations, and personal decision separate.
02
Ignoring the selected time frame
A daily chart can look very different from an intraday or weekly chart. State the time frame before drawing conclusions and avoid mixing signals from different horizons without a clear reason.
03
Looking only at confirming evidence
Once you have an idea, it is easy to search only for evidence that supports it. Ask what facts, levels, or conditions would challenge your view and include them in your notes.
04
Judging quality only by outcome
An outcome cannot fully prove whether the reasoning was sound. A decision journal helps you check whether you followed your method, understood the risk, and made assumptions explicit.
