How to keep a trading journal you'll still use in a month

Most trading journals are started with good intentions and abandoned within two weeks. That is not a character flaw. It is what happens when a habit costs more than it gives back, and most journals, bought or built, are designed to cost a lot. This guide is about the opposite: the smallest journal that still works, kept in a way that survives a bad week. It applies whether you use a notebook, a spreadsheet or an app.

Why journals die

Three things end a journal, usually in this order.

The first is time. If logging a trade takes five minutes, you will log the first ten trades and then start skipping the ones that happen fast or feel unimportant. Within a week the journal is incomplete, and an incomplete journal feels pointless, so you stop. The fix is not discipline; it is a journal that takes twenty seconds.

The second is too many fields. Templates with thirty columns, emotion scales from one to ten, a paragraph on market conditions: each field is a small question you have to answer while you would rather be watching the screen. Every field you add makes the next entry less likely. Start with five and earn the rest.

The third is silence. You log for two weeks and nothing comes back. No pattern, no number that changes how you trade. A journal that only stores is a diary, and few people keep a diary about losing money. The journal has to show you something, and it has to do that within the first month, or it will not get a second.

The five fields that are enough

For the first month, log exactly these for every trade, and nothing else:

1. Instrument. What you traded.
2. Entry and exit. The prices, or just the result in kronor if you prefer. Enough to know how it went.
3. Fees. Courtage both ways. Small per trade, surprisingly large per month.
4. A grade. A, B or C for how well you followed your plan, regardless of the result. More on this below.
5. One line. Why you took it, in your own words. Not an essay. One sentence.

That is it. No emotion scores, no market regime, no screenshots of every timeframe. A chart screenshot is worth adding if it takes one keystroke, as it does in LogBook, because looking at the chart later is how you remember the trade. If it takes a minute of cropping and uploading, skip it for now.

The grade deserves a word, because it is the field that makes the rest useful. An A is a trade you would take again exactly the same way, win or lose. A C is a trade you should not have taken, win or lose. Grading the process instead of the outcome is what lets you see, after thirty trades, whether your plan is the problem or whether you are the problem. We have a separate guide on what each field is for.

When to log: right after, never tonight

Log the trade within a minute of closing it. Not at the end of the day, not tonight, not on the weekend. The reason is simple: the one line about why you took the trade is only honest while you still remember what you were thinking. By the evening you will have a story instead, and the story is kinder to you than the truth was.

This is also why the form has to be short. Twenty seconds between two trades is possible. Five minutes is not, and so the trade gets logged tonight, or never. If you trade from a phone, the journal has to work on the phone. If you trade from two screens, keep the journal open on the second one.

One exception: if you are in a run of trades and logging would make you miss the next one, write the instrument and the result on a piece of paper and fill in the rest at the next quiet moment. The point is that the one line gets written before the story forms, not that you follow a rule.

The weekly review: fifteen minutes, three questions

Once a week, ideally on a day you do not trade, sit down with the week's trades and answer three questions. Write the answers down; a review you only think is a review you will not remember.

1. Which trades were A-grade, and how did they do as a group? Not each trade: the group. Five A-grade trades that lost money is information. Five C-grade trades that made money is a warning.
2. What did the C-grade trades have in common? Time of day, instrument, the state you were in, a loss just before. Usually there is one thing. Name it.
3. What is the one rule for next week? One. Not a new plan, not a list. A single sentence you can check each trade against, such as no trades in the first fifteen minutes or no second trade after a loss.

Fifteen minutes is enough for this when the week has ten to thirty trades. If it takes an hour, you are reviewing each trade instead of the week, and that is a different activity. The weekly review is about patterns, and patterns need a group.

If the journal can do the grouping for you, so much the better. A P&L calendar shows the shape of the week at a glance, and a breakdown by grade or time of day answers the first two questions in seconds. If you keep a spreadsheet, a pivot table does the same; our template guide shows how.

What to ignore for the first month

Everything else. Specifically:

• Statistics on fewer than twenty trades. A 70 % win rate after seven trades means nothing, and chasing it will change how you trade for the wrong reasons.
• Emotion tracking on a scale. If you want to note how you felt, put it in the one line: took it angry is more useful than a 3.
• Multiple setups and tags. Tag a setup when you have traded it ten times and can describe it in a sentence. Before that, the one line is enough.
• Optimising the journal itself. New columns, new colours, a better template. This is procrastination with a spreadsheet.
• Comparing yourself with anyone. The journal is about your trades against your plan. Other people's months are not data.

After a month, with thirty or more trades logged, you will know what you want to add. It is usually one or two things, and they will be things you actually use.

How you know it is working

The sign is not a better P&L, at least not at first. The sign is that you open the journal without making yourself. You look at the calendar on a Sunday because you are curious. You read the one line on an old trade and wince, and the next time that setup appears you hesitate. The weekly rule from two weeks ago is now just how you trade.

The second sign is that your C-grade trades get rarer. Not your losses: your C-grades. Losses are part of trading, and a journal full of A-grade losses is a journal of someone trading well in a bad month. A journal of C-grade wins is a journal of someone about to have a very bad month.

If after a month neither sign is there, the problem is usually the first section of this guide: the journal is costing too much or giving back too little. Cut fields, not the habit.

The checklist

• Five fields: instrument, entry and exit (or result), fees, grade, one line.
• Log within a minute of closing, from wherever you trade.
• A chart screenshot if it takes one keystroke; otherwise not yet.
• Fifteen minutes once a week: A-grades as a group, what the C-grades share, one rule for next week.
• Ignore statistics under twenty trades, emotion scales, extra tags and journal redesigns for the first month.
• Success is opening it without forcing yourself, and fewer C-grades. Not a bigger month.
