Almost every trader starts a journal. Almost every trader abandons it within two months.
The reason is rarely discipline. It is that the journal collects fifty fields, produces no insight, and takes fifteen minutes per trade to fill in. Eventually the cost is obvious and the benefit is not, so it stops.
A journal is worth keeping only if reviewing it changes what you do next week. Everything else is data entry.
The fields that actually matter
1. Entry, stop, and target — recorded before you enter
Not after. Before.
This is the single most important discipline in journaling, because it is the only way to know later whether you followed your plan or improvised. A stop written down after the trade closed is not a stop, it is a memory — and memories reshape themselves to protect us.
Recording these three numbers up front turns every trade into a testable claim.
2. Position size and the resulting R
Size without risk context is meaningless. What you want to capture is your initial risk in currency — the distance to your stop times your size — because that becomes the unit everything else is measured in.
If your risk per trade swings wildly between trades, that is itself the finding. Inconsistent sizing is the most common hidden reason a profitable strategy produces an unprofitable account.
3. Why you entered — one sentence
Not an essay. One sentence, written before or immediately at entry.
"1M bullish BOS after price swept London Low and retraced into the 5M FVG."
Two months later, this sentence is what lets you separate your A-setups from the trades you took because you were bored. Nothing else in the journal can do that.
4. Whether the trade matched your written rules
This is the field most journals skip, and it is the one that changes behaviour fastest.
A simple yes/no per rule is enough:
- Did the higher timeframe bias align? ✓
- Did I wait for the retracement? ✗
- Was risk within my limit? ✓
Over thirty trades, a pattern emerges that P&L will never show you: the specific rule you break most, and what it costs. Usually it is one rule, and usually it is expensive.
5. A screenshot of the chart
One image, marked with entry and stop. Take it at the time of entry, not after the outcome is known — post-hoc screenshots are quietly biased toward the story you want to tell.
What to stop logging
Emotions on a 1-10 scale. "Anxiety: 6" tells you nothing you can act on. If emotion mattered on a trade, one sentence in your notes captures it better than a number you will never sort by.
Market conditions as free text. "Choppy" and "trending" mean different things to you on different days. If a market regime genuinely matters to your strategy, define it as a rule with a threshold. Otherwise skip it.
Every economic event of the day. Unless your strategy trades news, this is noise you will never look at again.
Time-of-day precision beyond the session. Knowing you entered at 10:03 versus 10:07 will not change a decision. Knowing you entered during the first thirty minutes might.
The test for any field: can I imagine a review where this field changes what I do next week? If not, remove it.
The ten-minute weekly review
Data collection without review is a hobby. The review is where the value is, and it does not need to be long.
Step 1 — Sort by R-multiple. Look at your best three and worst three trades. Read the entry reason on each.
Step 2 — Count rule violations. Which rule did you break most this week? What did those trades cost in total R?
Step 3 — Group by setup. Which setup carried your results? Most traders find that one or two setups produce the entire edge and the rest lose money slowly.
Step 4 — Write one line for next week. Not five goals. One. "No entries before the retracement reaches the 5M FVG." Something specific enough to check next Friday.
The uncomfortable finding almost everyone gets
When traders first review compliance separately from profit, they discover something that stings: a meaningful share of their profitable trades broke their own rules.
That is not good news. A winning trade taken outside your plan is worse than a losing trade inside it, because it teaches you the wrong lesson and it is not repeatable. The account grew, the edge did not.
Separating "did I make money" from "did I follow my process" is the entire reason to keep a journal. If your journal only tracks the first one, it is a P&L statement with extra steps.
The short version
Log what you planned before you enter, whether you followed it, and why you took the trade. Review it for ten minutes once a week. Delete every field you have never sorted by.
