Understand it
A trader convinced the market will rise can ignore conflicting price action or unfavorable news. Research can suffer the same problem: testing only successful timeframes, excluding losing sessions or reporting only the winning variants. A useful countermeasure is a pretrade disconfirmation question: What evidence would make the setup invalid? During research, preserve rejected hypotheses and negative results.
If your long thesis requires a higher low, specify where it fails before entry. Afterwards, do not reinterpret every violation as 'still bullish' without retesting a different rule.
Watch for this misconception
Treating disagreement or losing evidence as proof that the market is temporarily wrong.
Write two observations that would cause you not to take a favorite setup.
