How to keep a trading journal you will actually use

Most traders agree that a journal helps, and most traders stop keeping one within a few weeks. The problem is rarely discipline. It is that the journal asks for too much at the wrong moment and gives nothing back. A journal you will actually use is short to fill in, fast to review, and shows you something you could not see on your own.

What to record for every trade

Split it into what the platform knows and what only you know.

• The facts: symbol, direction, entry, exit, stop loss, size, result after fees. These should never be typed by hand — import them or sync them from your platform.
• The plan: which setup this was, and why you took it. One line is enough.
• The state: how you felt going in — calm, bored, rushed, trying to win back a loss.
• A screenshot of the chart at entry, if the setup is visual.

Measure in R, not in money

A $300 win means little on its own. If you risked $100 it was a 3R trade; if you risked $600 it was half an R and a bad trade that happened to work. Recording your stop lets the journal express every result as a multiple of what you risked, and that is the number that shows whether your edge is real.

Review on a schedule

• Daily, two minutes: did I follow my plan today? Anything to note while it is fresh?
• Weekly, fifteen minutes: which setups made money, which lost it, and on which days and sessions.
• Monthly: is the equity curve moving because of the setups I believe in, or despite them?

Look for behaviour, not just statistics

Win rate and average R tell you what happened. The more useful questions are about how you behaved: did you take another trade minutes after a loss? Did your size go up after losing? Did you trade far more on some days than your plan allows, or outside the hours you normally trade? These patterns cost more than any single bad setup, and they are easy to miss trade by trade.

Simple Trading Journal checks these four habits automatically — revenge trading, raising risk after a loss, overtrading and trading outside your usual hours — across all your journals.

Keep it low effort

• Automate the facts so that journaling a trade takes seconds, not minutes.
• Use a short checklist before entering instead of long notes afterwards.
• Tag setups consistently — five setups used every day beat fifty used once.
• Keep separate journals for separate accounts, such as a prop challenge and a personal account.

Start small

You do not need a perfect system on day one. Record the facts automatically, add one line about why you took each trade, and look at it once a week. After a month you will have something no indicator can give you: evidence about your own trading.
