What Is a Trading Journal? A Practical Guide for Traders

A trading journal is a record of each trade and the decision behind it. It stores the prices and dates you would expect in a trade log, then adds your setup, risk, emotions, rule checks and review.

That extra context helps you answer a question a profit figure cannot: did you follow your process?

Trading journal vs trade log

A trade log records what happened:

• ticker, exchange and direction
• entry and exit dates
• entry and exit prices
• position size and fees
• profit or loss

A trading journal includes those facts and records why you acted:

• the strategy and entry thesis
• market conditions you considered
• stop, target and planned risk
• rules met or broken
• emotions before and after the trade
• an exit reason and lesson for next time

Suppose a closed SAMPLE.AU trade lost $450. The log shows the loss. The journal might show that the entry came before an RBA announcement, the position exceeded your planned size, and you broke a written rule. On another losing trade, the journal might show that you followed every rule and accepted the planned stop. Those trades have the same financial direction but give you different review tasks.

Why keep a trading journal?

One trade cannot tell you whether a strategy works or whether a behaviour repeats. A journal creates a consistent record that you can compare across many trades.

It helps you review:

• which strategies produced your recorded results
• whether position risk stayed within your plan
• how often you followed each rule
• whether certain emotions appeared around entries or exits
• which exit decisions differed from the original plan

Journaling does not promise better returns. It gives you evidence about your own decisions, including profitable rule breaks that a P&L-only review might reward by mistake.

Writing the entry thesis before a trade also makes vague reasoning visible. "This looks strong" gives you little to test later. "Price closed above the range, volume expanded, and the market index stayed above my filter" gives you specific conditions to review.

What to record in a trading journal

You do not need every possible field on day one. Start with the fields that explain the decision and make the result comparable.

Trade details

Record the symbol and exchange, direction, dates, prices, units and fees. Add the actual fill rather than the price you hoped to receive. For an open trade, keep the current position separate from a completed result.

Setup and strategy

Name the strategy and write the entry criteria in plain language. If you use a rules checklist, mark each rule at the time you enter. Attach a chart image when it adds context that the numbers cannot preserve.

Risk plan

Record your stop, target and dollar risk before entry. If a hypothetical trade buys 200 units at $25 with a stop at $24, planned risk is:

($25 - $24) x 200 = $200

If the trade later makes $400 after fees, the result is +2R because $400 / $200 = 2. Recording the original risk prevents you from redefining the plan after seeing the outcome.

Decision context

Write a short thesis, the market conditions you used, and any event that affected the setup. Keep the entry concise enough that you can complete it consistently.

Emotions and rule compliance

Choose words that describe your state, such as calm, anxious or impatient. Then record whether you followed the planned rules. This creates data you can review without claiming that an emotion caused the result.

Exit review

After the trade closes, record the exit reason, actual R-multiple, what followed the plan and what you would change. Write one specific lesson. "Wait for the daily close required by the strategy" is more useful than "be disciplined."

A complete trading journal example

This hypothetical entry shows how the fields work together:

The example does not label the trade good or bad. It preserves enough information to compare the decision with the plan and with later trades using the same strategy.

How to review your trading journal

Review closed trades on a schedule you can maintain. A short weekly review can check recent entries, missing fields and rule breaks. A monthly or strategy review can compare a larger group.

Ask:

1. Which trades have enough planned-risk data to calculate R?
2. Which strategy produced each result?
3. Did rule-following trades differ from rule-breaking trades?
4. Which exit reasons repeat?
5. What one process change will you test next?

Do not invent a universal number of trades that makes a pattern reliable. A small sample can prompt a question, but it cannot support the same confidence as repeated observations across varied market conditions.

A 15-minute weekly review

Use this article's short routine as a starting point:

1. Fill any missing exit reasons, fees or rule checks.
2. Sort the week's closed trades by strategy.
3. Compare planned risk with the recorded result.
4. Read the notes on rule breaks and early exits.
5. Choose one process change to test next week.

Keep the change narrow. If you alter entry filters, position size and exit rules at once, the next group of trades cannot show which change mattered.

A monthly strategy review

Group trades by strategy and confirm that each result has the inputs required for the metric. Compare win rate with average win and average loss rather than reading it alone. Review R-multiple only for trades with a usable initial-risk value.

Then read the journal entries behind an unusual result. A strong average can come from one large trade, while repeated small losses may share the same rule break. The numbers identify where to look; the notes explain what you recorded at the time.

Common trading journal mistakes

Recording only winners and losses

P&L cannot explain the process. Add the planned risk, setup and rule review so you can distinguish a sound decision from a favourable outcome.

Writing long diary entries

A journal needs enough context to compare trades. Several focused fields often work better than an unstructured page that you cannot scan later.

Changing the fields every week

Consistent labels make comparisons possible. Keep a small core set, then add a field when you have a clear question it can answer.

Reviewing without making a change

End each review with one testable action. For example, require the daily close in the next range-breakout entries, then compare those trades with the earlier group.

Rewriting the plan after the result

Record the setup and risk before entry. If you wait until the trade closes, memory can turn an improvised decision into a planned one. Keep the original note and add the exit review separately.

Tracking too many fields

A long template can make every entry feel like paperwork. Start with identification, strategy, risk, thesis, rules and exit review. Add a field when you have a recurring question that the journal cannot answer.

Spreadsheet, notebook or trading journal app?

A paper notebook works for decision notes but makes grouping and calculation slow. A spreadsheet gives you control over fields and formulas, though you must maintain the structure and catch errors yourself.

A dedicated app can calculate metrics and connect each trade with strategy and behavioural fields. Choose the format you will update consistently and can export. The useful record is the one you complete at entry and return to after exit.

Start a trading journal in Swingfolio

Swingfolio combines trade records with strategy and behavioural review. The trade form records entry details, strategy, stop, target, fees, notes and entry emotions. When you close a trade, you can add exit emotions, rule compliance and reflection tags.

Analytics calculate results from the trades with the required data, including win rate, profit factor and R-multiple statistics. Behavioural views let you review recorded emotions and rule compliance. The software handles calculations from your inputs; you still supply the thesis and honest review that make the journal useful.

Create your first entry before your next trade. Record the setup, planned risk and rule checklist, then return after the exit to write one lesson. To keep that process in one place, Start the 30-day trial.
