7 Common Trading Journal Mistakes
Most journals fail because they are too complicated or never reviewed—not because they lack data. A simple, consistent process beats short-lived perfection.
1–3: Weak records
Logging only P&L, delaying entries and using inconsistent strategy names make later analysis unreliable.
4–5: Faulty analysis
Tiny samples and win-rate obsession create an incomplete picture. Include win/loss size, Profit Factor, risk and plan adherence.
6–7: No action
An unreviewed journal is only an archive. Trying to fix everything at once also fails. Choose one important pattern and one clear action each week.
