What is a trading journal and why keep one?

A trading journal is a record of every trade you take: what you traded, when you entered and exited, how much you made or lost, and why you made the decision. Your broker statement tells you what happened. A journal adds why, which is the part you can actually improve.

Why traders keep one

• It replaces memory with data. Most people remember their best trades and forget the ordinary losers. A journal shows the real win rate, the real average loss and the real cost of fees.
• It finds patterns you cannot feel. You may lose money almost only in the first ten minutes, or only on Fridays, or only when you trade a particular setup. A journal shows this in numbers.
• It makes mistakes visible. Tag a trade as FOMO, revenge trade or exited early and, after a few weeks, you can see what each habit has cost you.
• It gives you something to review. Changing your approach based on a feeling is guessing. Changing it based on 50 recorded trades is testing.

What goes in a trading journal

At minimum: date and time, symbol, direction, entry and exit price, size, and profit and loss after fees. To make it useful, add the setup you were trading, your planned stop and target, any mistakes, a one-line note, and a screenshot of the chart.

If that sounds like a lot of typing, it does not have to be. Your broker can export a CSV with most of those fields, and a tool like OptiqJournal imports it so you only add the setup and the notes. See how to export trades from your broker.

How to start in five minutes

1. Export your recent trades from your broker.
2. Import them into a journal and look at the P&L, win rate and average win against average loss.
3. Pick your three biggest losses and tag the mistake on each.
4. At the end of each day, write two sentences: what went well, and one thing to change.

That is enough to begin. Detail can come later; consistency matters more than completeness. For a full list of fields see the trading journal template.

How long before it pays off

Statistics on a handful of trades are noise. Many traders wait for 30 to 50 trades in a setup before changing anything, and review weekly rather than after every trade.
