The trading journal
A trading journal is a structured record of every trade you take: the reason, the plan, the management, the emotion and the outcome, reviewed on a schedule. It is the highest-leverage habit in trading because it is the only thing that turns a pile of noisy results into a feedback loop you can act on.
Emotions, rules, confluences, screenshots and a P&L calendar built in. Cancel before it ends and you pay nothing.

Why journaling works when it works
Trading gives terrible feedback. A good decision can lose, a reckless one can win, and the result arrives too soon after the decision for your brain to separate the two. Left to memory, you will remember the trades that were vivid rather than the trades that were representative, which is how traders end up confidently describing an edge they do not have.
A journal fixes this by making the sample bigger than the anecdote. Fifty logged trades read together will tell you things no individual trade can: that a setup you like is break-even after costs, that your losers are twice the size of your winners on Fridays, that the trades you took outside your plan cost you more than any losing streak. None of that is visible from inside a single trade, and all of it is obvious across fifty.
What to record, and why
Every field here earns its place by answering a question you will eventually ask.
The review routine
Logging is the cheap half. The review is where a journal either changes your trading or becomes a diary you stop writing. Three passes, on a schedule, each answering a different question.
Finish the entries while the details are still accurate. Note rule breaks immediately, before they get rationalised into good decisions.
Read the week as one sample. Which setups appeared, which you skipped, where size drifted, and what the losers had in common.
Only here do the statistics mean anything. Expectancy after costs, profit factor, drawdown, and performance split by setup, session and day.
The number to trust above the others is expectancy after costs, because it is the one that survives contact with a broker. Win rate on its own says nothing: a 70% win rate with losers three times the size of winners is a losing system, and a 35% win rate can be excellent. How to read those three numbers together.
Why most journals get abandoned
A row that says "AAPL, +$140" is a receipt, not a journal. Without the reason, the plan and the state you were in, there is nothing to learn from and nothing to change.
The writing is not where the value is. The value is in reading fifty trades at once and noticing the pattern that is invisible from inside any single one.
A good trade can lose and a bad trade can win. Grade the decision against the rules you set beforehand, then let the sample tell you whether the rules are any good.
Winning streaks hide sizing drift and rule-bending just as reliably as losing streaks expose them. A fixed schedule beats a mood-driven one.
Spreadsheet, notebook or app
A notebook is the best place to start, because the friction is zero and the habit matters more than the format. A spreadsheet is the natural second step and takes most traders a long way: it sorts, filters and computes. It runs out when you want screenshots attached to entries, psychology tracked next to results, R-multiples and expectancy calculated for you, and a calendar that shows which days actually pay. At that point the upkeep is what kills the habit, not the tool.
Dedicated journals remove that upkeep, which is the whole argument for them. The full spreadsheet comparison, and which journal suits which kind of trader.

Questions
What is a trading journal?
A trading journal is a structured record of every trade you take: the setup, the plan, the size, the outcome and your state of mind, reviewed on a schedule. It exists to convert scattered results into a feedback loop, so you can tell which of your decisions actually make money rather than guessing from memory.
What should I record in a trading journal?
At minimum: instrument, date and session, the setup name, the entry, stop and target you planned before entering, position size expressed in R, the exit and why you took it, a screenshot at entry, your emotional state, and whether you followed your rules. The last three are the ones most traders skip and the ones that explain the outliers.
How often should I review my trading journal?
A short pass at the end of each trading day to log details while they are accurate, a longer weekly review to read the week as a sample, and a monthly or quarterly review to look at the metrics across a few hundred trades. Daily reviews catch mistakes, but only the larger samples can tell you whether an edge exists.
Is a spreadsheet good enough for a trading journal?
A spreadsheet is a perfectly good start and better than nothing. It stops being enough when you want screenshots attached to trades, psychology tracked alongside results, R-multiple and expectancy computed automatically, or a calendar view that shows which days you actually make money. Most traders abandon the spreadsheet not because it is wrong but because the manual upkeep makes them stop logging.
Do trading journals actually improve performance?
A journal cannot give you an edge you do not have. What it does is make your existing behaviour measurable, so recurring and expensive mistakes such as oversized revenge trades, skipped setups and drifting stops become visible instead of remaining anecdotes. The improvement comes from acting on what the review shows, not from the act of recording.
Is there a free trading journal?
Yes: several journals have a free plan, and a spreadsheet costs nothing if you will keep it updated. The journal on this site, with emotions, rules, confluences, screenshots and a P&L calendar, comes with Pro, which starts with a 3-day free trial: a card is required, and you pay nothing if you cancel before it ends. There is also a live demo you can browse with no signup at all to see the analytics against a populated account first.
