Journal
Track, measure, improve. The tool that turns good traders into great ones.
First — Why This Matters
🔍 The Athlete's Playback System
Every professional athlete reviews game footage after every match. Not because they enjoy watching themselves lose, but because the footage reveals patterns that feelings miss: the foot placement that caused the slip, the positioning that created the opening, the fatigue moment that led to the error.
Your trading journal is your game footage. Without it, you are an athlete who plays every match but never watches the replay. You repeat the same mistakes month after month because you have no system to identify, quantify, and fix them.
🔎 REAL SCENARIO
A trader journaled for 6 months (180 trades). His weekly reviews revealed: London session WR = 57%, Asian session WR = 29%. He was spending 8 hours/week on Asian trades that were costing him money. He stopped trading Asia. Over the next 3 months, his account grew 42% faster — not by getting better, but by stopping the thing that was hurting him. The journal found it. Awareness alone never did.
01 — The Improvement Cycle
Record → Review → Discover → Adjust
The journal is not a static record. It is a living feedback loop that makes you better every week.
02 — The Impact
6 Months: Journal vs No Journal
The trader without a journal repeats the same mistakes. The trader with a journal improves each month — better WR, better R:R, compounding growth.

Grade Your Current Journal
How does your journaling practice measure up?
Do you record every trade?
Do you include screenshots?
Do you record emotional state?
Do you write lessons learned?
How often do you review?
Have you made a change based on journal data?
06 — The One-Change Rule
Fix One Thing at a Time
Your journal will reveal multiple issues. The temptation is to fix everything at once. Resist it. Changing 5 things simultaneously means you cannot measure which change helped.
The Scientific Method for Trading
1. Journal reveals the biggest leak (e.g., Asian session trading)
2. Make ONE change (stop trading Asia)
3. Trade 30-50 trades with the change
4. Review: did the change improve results?
5. If yes, keep it. If no, revert. Either way, move to the next issue.
💡 The Lab Analogy: A scientist testing a new drug does not change the dosage, the timing, the delivery method, and the patient group all at once. They change ONE variable and measure the result. Your trading journal is your laboratory. One variable at a time.
07 — Tools & Templates
Where to Keep Your Journal
Spreadsheet (Google Sheets / Excel) — Most flexible. Custom columns, formulas for auto-calculating WR, R:R, EV. Free. Best for traders who like data.
Dedicated Journal App (Tradervue, TradeZella, Edgewonk) — Auto-import trades. Built-in analytics. Cost £15-40/month. Best for traders who want analysis done for them.
Notion / Notes App — Good for screenshots and written reflections. Lacks automatic calculations. Best combined with a spreadsheet for the numbers.
ATLAS Prop Dashboard — Built-in trade journal with session tracking, R:R calculations, and narrative strips. Designed for the ATLAS workflow.
💡 The best journal is the one you actually use. A simple spreadsheet that you fill in after every trade beats a £40/month app that you abandoned after a week. Start simple. Upgrade later if needed.

Journal Quick Reference
RECORD = Every trade. 13 fields. Screenshots before and after. Emotional state. Lessons learned.
REVIEW = Weekly. 6 questions: session WR, model EV, trigger performance, R:R achieved vs planned, rule breaks, emotional patterns.
CHANGE = One thing at a time. 30-50 trades per change. Measure impact. Scientific method.
QUANTIFY = Turn feelings into numbers. “I think I lose in Asia” → “Asia WR = 29%, costing £340/month.”
NEVER = Skip trades. Review without acting. Change 5 things at once. Journal only losses.
