A journal turns a series of isolated trades into data you can review. The value is not in the act of writing but in recording enough to see patterns in what you do well and where you bleed money.
Record the setup, not just the result
For each trade, capture the instrument, direction, entry and exit, size, the time and a note on the reason you took it. Screenshots of the chart at entry are useful because memory is a poor record of what you actually saw.
Also record what you were trying to accomplish: a defined stop, a target, a time frame, and the risk/reward you expected. This lets you later compare the plan to what actually happened.
Include costs and context
Track fees, funding if it applies, and the approximate slippage you experienced. Results that ignore costs overstate performance, especially across many small trades.
Note the broader market context in one line, such as whether the wider market was trending or ranging, since a setup may work in one regime and fail in another.
Review on a schedule
A review should be periodic rather than after every trade, so you have enough samples to see something meaningful. Look for patterns: which setups produce results, which mistakes repeat, and whether you are following your own rules.
Keep the review honest and specific. Instead of a note like I was emotional, record the concrete behaviour, such as moving a stop or taking an extra position, so you can change the process next time.
Frequently asked questions
What are the minimum fields I should record for each trade?
At minimum: instrument, direction, entry and exit, size, the time, the reason for the trade, your planned stop and target, and the fees and slippage you experienced. A chart screenshot at entry is strongly recommended.
How often should I review my journal?
Review on a regular schedule once you have a reasonable number of trades, rather than after each one. This gives you enough samples to spot reliable patterns in your process and results.
How do I keep a journal useful instead of just a log?
Record the plan, not only the outcome, and include costs and market context. Then review on a schedule and turn vague conclusions into specific, changeable behaviours you can track next time.
