Overview
A trading journal is the single highest-leverage habit a developing trader can build. It converts a blur of trades into data you can learn from — turning "I think I trade better in the morning" into something you can actually measure and fix.
What to log
| Date | Setup | Entry / Stop / Target | Size · Risk (R) | Result (R) | Grade | Note |
| 06-12 | Bull flag | 50.2 / 49.4 / 52.0 | 120 sh · 1R=$0.80 | +1.8R | A | Followed plan, waited for retest |
| 06-12 | ORB | 31.1 / 30.6 / 32.5 | 200 sh · 1R=$0.50 | −1R | A | Valid setup, clean stop — good loss |
| 06-13 | (none) | — | — | −1.6R | F | Revenge trade after the loss — tilt |
The weekly review
The journal only pays off when you read it back. Once a week, scan for patterns: which setups are your best and worst in R? When do your mistakes cluster (time of day, after a loss, certain symbols)? What does a "good loss" look like versus a rule-break? The review is where improvement actually happens — entries no one revisits are wasted effort.
Grade the process, not the profit
Every trade gets a grade for execution, independent of the result. A loss taken exactly to plan is an A — a good loss. A winner from breaking your rules is an F, because that behaviour eventually ruins you. Grading process is how you separate skill from luck and reinforce the right habits.
Honest assessment
A useful journal captures
- The setup, and whether it met your rules.
- Entry, stop, target — and risk in R.
- A process grade (did you follow the plan?).
- A one-line lesson or emotion note.
A useless journal
- Only P&L, with no setup or grade.
- Filled in days later from memory.
- No review — entries no one ever reads.
- Grades by money, so good losses look 'bad.'
Practice
Why grade trades by process instead of profit?
Because outcome is noisy over one trade. A disciplined loss is an A; a profitable rule-break is an F. Grading process is what actually improves you and separates skill from luck.
What's the single most valuable journal habit?
The regular review — reading back entries to find repeating mistakes and your best/worst setups. A journal no one reviews is just data.
Why log everything in R?
R (risk multiples) normalises trades of different sizes, so you can measure expectancy and compare setups on equal footing.
