Trading Journal
A trading journal is a structured record of every trade you make, including why you entered, how you managed it and what happened. It turns your results, habits and mistakes into something you can measure and improve.
What goes into a trading journal
The basics are the facts of each trade: date and time, asset, direction (long or short), entry price, position size, stop loss, target, exit price, fees and the final profit or loss.
The more useful part is the context: why you took the trade, which setup or signal you used, how confident you were, how you felt, and whether you followed your own plan. A screenshot of the chart at entry and exit helps a lot when you review later.
Why it helps
Memory is unreliable and flattering. Without records, most traders remember their big wins and forget the small, repeated losses. A journal shows your real win rate, your average win compared with your average loss, and which kinds of trades actually work for you.
It also exposes behaviour: trading too often after a loss, moving stops, or taking setups you never planned. Seeing these patterns in writing is often what changes them.
An example
Say you review 40 journalled trades. Your overall result is slightly negative. Sorting by setup, you see that breakout trades made money while trades taken late at night after a loss lost almost every time. Without the journal, both would have blurred into one disappointing month. With it, you know which habit to drop.
Common mistakes
Recording only the numbers and skipping the reasons, which makes the review shallow. Logging only some trades, usually skipping the embarrassing ones. And never reviewing the journal at all, so it becomes a diary rather than a tool.
A simple spreadsheet is enough for most people. Consistency matters far more than the software, and a regular weekly or monthly review is where the value comes from.

Frequently asked questions
What should I write in a trading journal?
At minimum the entry, exit, size, stop, fees and result of each trade, plus your reason for taking it and whether you followed your plan. Notes on emotions are optional but often revealing.
Is a trading journal useful for long-term investors?
Yes, in a lighter form. Recording why you bought, what would make you sell and reviewing it periodically helps avoid drifting decisions and hindsight bias.
Do I need special software for a trading journal?
No. A spreadsheet or notebook works. Dedicated tools can import trades automatically, but the reflection and review are what make a journal useful.
