How to journal trades that actually improve your process

Most journals become a screenshot dump plus PnL. That feels productive, but it doesn’t tell you whether your edge is real or whether your execution is leaking money.

A useful journal answers only three questions: Did I follow my process? Which setups actually pay? Which mistakes are most expensive?

If a field does not help answer one of those three, remove it.

1) Setup tag: one normalized label from your playbook (for example: pullback continuation, range reclaim, failed breakdown).

2) Thesis in one sentence: what had to happen for this trade to work.

3) Invalidation: exact price/condition that proves the idea wrong.

4) Planned R:R at entry: written before the trade, not after.

5) Execution grade (0-5): did you follow your own entry, stop, and size rules.

6) Mistake tags (if any): FOMO entry, moved stop, oversized, revenge trade, skipped checklist.

7) Lesson in one line: what you will repeat or stop next time.

5 = Fully compliant: setup valid, risk sized correctly, no rule breaks.

4 = Minor deviation: slightly early/late entry, but risk and invalidation respected.

3 = One meaningful mistake: still within risk limits, but process leak present.

2 = Multiple errors: entry/exit/risk decisions violated your own rules.

1 = Emotional trade: weak thesis, checklist ignored, poor risk control.

0 = No defined plan before entry.

This score is about process quality, not profit outcome. A losing 5/5 is healthier than a winning 1/5.

Step 1 (5 min): sort by setup tag and note win rate + average R per setup.

Step 2 (10 min): group by mistake tag and total the R lost by each mistake type.

Step 3 (10 min): isolate your top two green behaviors (what to keep) and top one red behavior (what to ban).

Step 4 (5 min): write one rule for next week, specific and measurable.

Example weekly rule: 'No entry unless pre-flight score is Ready and stop is defined before position size is calculated.'

A) Best performing setup by expectancy:

B) Worst performing setup by expectancy:

C) Most expensive mistake tag this week:

D) % of trades with 4/5 or better execution:

E) One process rule for next week (single sentence):

Keep this template short. The goal is consistency, not perfect prose.

Use setup tags consistently so Stats can compare expectancy by playbook pattern.

Use mistake tags aggressively so Journal Coach can surface the biggest leaks by dollar/R impact.

Run your review once weekly at a fixed time. No weekly review = journal turns into storage.

Treat each closed trade as a case study, not a memory log.
