Ask a trader why they lost money and you will get a story. Ask their journal and you will get a pattern — usually one that contradicts the story. That gap is why journalling is the highest-return habit available to a developing trader.
Why memory fails
- You remember the dramatic trades — the big win, the disaster — and forget the twenty ordinary ones that actually determine your results.
- Hindsight rewrites intention. After the fact, you recall having a clear reason. The journal shows whether you wrote one down at the time.
- Outcome contaminates process. A rule-breaking trade that won gets remembered as good judgement.
What to record
Enough to answer questions later; not so much that you stop doing it. The most common failure mode is an elaborate template abandoned after two weeks.
| Field | Why it matters |
|---|---|
| Date, instrument, direction | Basic identification |
| Setup name | Lets you compare performance by setup type — the single most valuable cut |
| Entry, stop, target | Records the plan as it existed before the outcome |
| Planned risk (£ and %) | Reveals size discipline over time |
| Screenshot at entry | The chart as you saw it, before hindsight edits your memory |
| Reason, in one sentence | If you cannot write it, you should not be in the trade |
| Outcome in R | Normalises results across instruments and position sizes |
| Did I follow the plan? Y/N | The most important field on the list |
| Session / time of day | Frequently reveals that results cluster in specific hours |
The field that matters most
“Did I follow the plan?” splits every trade into four categories, and the distinction they draw is the point of the whole exercise:
| Followed plan | Broke plan | |
|---|---|---|
| Won | Excellent — repeat this | Dangerous — you were rewarded for bad behaviour |
| Lost | Fine — this is the cost of doing business | The only genuinely bad outcome |
Most traders judge themselves by the top-left/bottom-left split — win or lose. The useful split is left column versus right column. A losing trade taken correctly is a good trade. A winning trade taken by breaking your rules is the most expensive kind, because it teaches you to do it again.
Reviewing it
- 1Weekly, 20 minutes
Read every trade from the week. Count plan-followed versus plan-broken. Note any repeated error.
- 2Monthly, by setup
Group trades by setup name and compute expectancy for each. Most traders discover one setup carries the account and another quietly drains it.
- 3Monthly, by time and session
Group by hour or session. Results are very often concentrated in a narrow window.
- 4Quarterly, the honest question
Is the equity curve rising? Is plan adherence improving? If neither, the problem is not your indicator settings.
Metrics worth computing
- Expectancy in R — average R per trade. The single headline number.
- Win rate — meaningless alone, essential alongside average win and loss.
- Average win / average loss — is the ratio what you planned, or are you cutting winners early?
- Plan adherence rate — percentage of trades taken to plan. Target above 90%.
- Maximum drawdown — the worst peak-to-trough dip, and how long recovery took.
- Expectancy by setup — the cut most likely to change what you do next.
