How to Keep a Trading Journal (The Psychological Way)
By Sofia Harchich | Trading Psychologist & Behavioural Finance Writer | thewealthmirror.com
A journal that only records what happened on the chart will tell you what you did. A journal that records what was happening internally will tell you why — and why is the only part that actually changes.
Trading journal psychology starts from a different question than most journals ask. Most trading journals look the same: entry price, exit price, position size, P&L, maybe a line about the setup. This kind of record is useful for performance review, but it answers a narrow question — did the trade work — while leaving the more important question untouched: what was actually driving the decision to take it.
A trader can review a hundred entries logged this way and still repeat the same psychological mistake on the hundred-and-first, because the journal never captured the internal state that produced it in the first place.
Why the Standard Trading Journal Misses the Point.
Trading journal psychology exists because of what a typical journal misses. A typical journal tracks outcomes; it rarely tracks the decision-making conditions that preceded them — which means it can show that a pattern exists (recurring losses on a particular setup, say) without ever revealing why that pattern keeps recurring.
This matters because most repeated trading mistakes aren’t technical. A trader rarely keeps making the same charting error indefinitely; that kind of mistake gets corrected quickly once identified. What persists are the psychological patterns — overtrading after a win, hesitating after a loss, exiting early out of anxiety — and none of these show up in a log of prices and outcomes. They show up in the internal state at the moment of decision, which most journals never ask about.
A price-only journal can tell you that you lose money on Fridays. Only a psychological journal can tell you that you trade differently on Fridays because the week’s losses have accumulated by then.
What Trading Journal Psychology Actually Tracks.
Alongside the standard entry and exit data, a psychological journal adds a layer that captures internal state, not just market outcome:
- Pre-trade emotional state — a simple scale (calm, mildly tense, activated) noted before entry, not after
- The reason for the trade, in one sentence, written before entering — this exposes the gap between planned setups and impulsive ones
- Physical sensations noticed at entry — tightness, urgency, a flat calm — tracked as data, not commentary
- What happened immediately before the trade — a loss, a win, a period of boredom, an external stressor unrelated to markets
- The feeling at the moment of exit — relief, satisfaction, fear, frustration — and whether that feeling matched the technical reason for exiting
- One line on what the trade revealed, written after the fact, connecting the pattern to something broader than this single instance
This isn’t more work than a standard journal — it’s a few additional short entries per trade. The difference is in what those few extra lines eventually reveal once a pattern has enough data points behind it.
The goal isn’t to journal more. It’s to journal the part that actually explains the behaviour, not just the part that records it.
A Simple Practical Template.
Trading journal psychology comes down to five fields, tracked consistently:
- Before the trade: Setup and reason (one sentence) → Emotional state (1–10) → Physical sensation noticed, if any
- At entry: What just happened in the last hour, on the chart and off it
- During the trade (if held longer than a few minutes): Any urge to exit early or add to the position, and what triggered it
- At exit: Reason for exit (technical signal vs. feeling) → Emotional state at close
- End of day or week: One line connecting today’s pattern to a previous entry — does this state keep producing this behaviour?
Here’s what one filled-in entry looks like on a real position. Before: GOLD (XAU/USD), long on a retest of broken structure, 6/10 calm, slight urgency noticed. At entry: price had just spiked on a data release; the setup was valid, but the urgency was about not missing the move, not about the setup itself. At exit: closed two hours early, 8/10 relief, technical reason given was “protecting profit,” real reason was discomfort holding a position that large overnight. That single entry, read back a month later alongside four similar ones, is what eventually reveals the pattern — not any one trade on its own.
This structure takes under two minutes per trade once it becomes routine, and the value compounds — a single entry tells you little, but twenty entries reviewed together will reliably surface the pattern a trader has been unable to see while inside any single trade.
The Deeper Layer: Why Self-Observation Changes Behaviour.
The practice of noting an internal state without immediately acting on it has a name in contemplative traditions: witnessing. Eckhart Tolle describes this as the difference between being consumed by a thought or feeling and observing it — a small shift in vantage point that, on its own, begins to loosen the feeling’s grip.
A trading journal that captures emotional and physical state at the moment of decision is, functionally, a witnessing practice. The act of writing “activated, 7/10, tight chest” before entering a trade creates a half-second of separation between the feeling and the action — and that half-second is often enough for the more deliberate parts of the brain to weigh in before the impulsive ones take over completely.
Patterns that operate unconsciously lose a striking amount of their power the moment they’re named and tracked consistently. A trader who has logged “anxious after three consecutive losses, tends to oversize the next trade” five separate times can no longer treat that pattern as a one-off bad day. It becomes data — visible, specific, and far harder to unconsciously repeat once it’s been witnessed this clearly, this many times.
Start Here:
Trading journal psychology becomes real once it’s practiced, not just read about. Start here:
- Add one new field to your existing journal: emotional state (1–10) before entry, not after
- Write the reason for each trade in one sentence before opening it, not as a retrospective justification
- Note any physical sensation at entry and exit for the next ten trades — tightness, calm, urgency
- After two weeks, review the entries together and look for one state that consistently precedes one behaviour
A pattern that’s been written down enough times stops being a mood and starts being information. The page was never empty because there was nothing to say — it was empty because the words hadn’t been let onto it yet.
