Trading psychology is not simply about “controlling emotions”. In practice, the useful question is how your behaviour changes under pressure: after a loss, after missing an opportunity, during a winning streak or when the market does not behave as expected.
From feelings to observable patterns
A journal cannot know exactly what you were thinking, but it can record objective signals: time between trades, position size, plan adherence, entries outside your session, strategy switching, stop changes or sudden increases in trading frequency.
What to track
- Context: market, session, strategy and timeframe.
- Risk: planned size versus actual size.
- Process: whether the entry met the setup conditions.
- Mistakes: chasing price, anticipating, overtrading or unplanned changes.
- Sequence: what happened in the immediately preceding trades.
Separate outcome from decision quality
A good decision can lose and a poor decision can win. Reviewing only P&L can reward behaviour that happened to work once. Cross the outcome with plan adherence and mistakes to evaluate the process.
Compare samples, not anecdotes
Look for repetition. For example, compare trades taken after a loss with your overall sample: frequency, average risk, expectancy, mistakes and time between entries. A repeated difference is more useful than remembering one session.
Test one measurable intervention
If you detect a pattern, change one rule: mandatory pause, additional checklist, maximum number of attempts or temporary risk reduction. Then compare a new block of trades with the previous one.
