Every trader has two or three expensive habits. They feel invisible because they're emotional, but they're perfectly visible in data — if you tag them. Psychology journaling is simply attaching the reason to each result and letting sample size do the confronting.

The Six Tags That Explain 90% of Losses

1. FOMO entry — chased after the move started
2. Revenge sizing — doubled risk after a loss
3. Moved my stop — widened risk mid-trade
4. Early exit — cut a winner against plan
5. No setup — boredom trade
6. News gamble — entered seconds before red folder

Tag honestly for thirty trades and sort by total R lost. Most traders find two tags produce over 70% of damage. That's not psychology anymore; that's arithmetic.

From Pattern to Rule

Each dominant tag becomes a mechanical rule: revenge tag → mandatory 30-minute cooldown timer before next order; moved-stop tag → hard alert at breakeven. Rules stick when your own equity curve proves why they exist.

Weekly Review Ritual

Filter mistakes-only view, read the notes aloud, pick ONE change for next week. Single-change reviews compound; ten-point manifestos get abandoned by Wednesday.
