A journal goes beyond an exchange's trade history. Next to prices and P&L, it captures the setup, the planned stop and target, the R-multiple, screenshots, notes and mistakes. Over time it becomes a data set: you can see win rate, expectancy and drawdowns by setup, session, symbol or emotion, and replace impressions about your trading with facts.
Example
After three months, a trader's journal shows 180 trades with an overall expectancy of +0.05R. Filtered by tag, breakouts in the New York session make +0.35R per trade, while trades tagged FOMO lose 0.6R each and trades taken after two losses in a row lose 0.4R each. Dropping those two groups would have turned a barely profitable quarter into a clearly profitable one.
Why it matters
Without records, traders remember their best trades and their most painful losses, and little in between. A journal shows the real numbers, which is what makes it possible to fix specific leaks instead of vaguely trying harder.
Common mistake
Logging only the numbers. Exchange exports already have prices and P&L. The useful part is the context: why you took the trade, whether it matched your plan and how you felt. Without it, you cannot tell a good loss from a bad one.

FAQ
- What should a trading journal include?
- At minimum: date, symbol, direction, entry, stop, target, exit, size, fees, result in R, the setup name and a short note on execution and emotions. Screenshots help a lot in reviews.
- Spreadsheet or journal app?
- A spreadsheet works for a few trades a week. Apps that sync trades from your exchange remove manual entry and calculate statistics such as R, expectancy and drawdown automatically.
- How often should I review my journal?
- Briefly after each session and in more depth once a week. Look for patterns across many trades instead of judging single results.
