Confirmation Bias

How it shows up in trading

• After going long, you read only the bullish posts in your feed and dismiss anything bearish as noise.
• You re-examine your chart to find indicators that "still" support your bias, even after the structural argument has broken.
• You move your stop because you’ve become attached to being right.

Why it’s especially dangerous in markets

Markets reward updating beliefs in real-time. A trader who can say "I was wrong, the new evidence is XYZ" within minutes outperforms one who clings to a thesis for hours waiting for redemption.

Counter-tactics

• Steel-manning the opposite side — before entering, write the strongest bear case (or bull case) in 1-2 sentences. Treat that case as a living invalidation.
• Pre-commit invalidations — concrete chart events (e.g., "if price closes below 1.0820 on H4") that flip your view.
• External devil’s advocate — a peer or even an AI prompt that argues the opposite. Treat their points seriously.
• Track P&L by thesis, not by direction — were you right for the right reason?

Every Radar setup ships a Signal rationale listing the conditions that invalidate the call, not just the ones supporting it. Reading both sides of the model before clicking is one of the cheapest edges in trading.
