How to Keep a Trading Journal: What to Record After Each Trade

A trading journal is useful when it lets you reconstruct the decision behind a trade, compare similar situations, and turn repeated observations into changes you can test.

In short: record trade facts, decision context, execution and one actionable takeaway. Avoid collecting fields you never use during review.

Why keep a trading journal

Memory compresses past decisions. A structured record preserves the same facts for every trade, which makes comparison more reliable. The goal is not to label every winner as good and every loser as bad, but to separate process quality from outcome.

What to record

Trade facts

Date, instrument, side, size, entry, exit, fees and final PnL.

Setup and context

Reason for entry, invalidation condition, key level and expected scenario.

Execution

Position changes, stop movement, partial exits and deviations from the plan.

Takeaway

One specific observation that can be checked in the next similar situation.

Separate the plan from the result

Write the setup and invalidation before entry when possible. Add the actual result and execution note after the position is closed. This reduces hindsight editing of the original plan.

Review a series, not only one trade

Weekly or monthly review is where patterns become visible. Compare setups, instruments, time periods and outcomes. Use trader statistics for quantitative review and the trading calendar to inspect performance by day.

Common journaling mistakes

Recording only losses

You miss the conditions behind repeatable good decisions.

Writing too much

A process that takes too long is difficult to sustain after every session.

Never reviewing

Without review, the journal becomes storage rather than feedback.

Looking only at PnL

Outcome alone cannot explain whether the decision process was consistent.

Spreadsheet, template or online journal

A spreadsheet can be enough for a start. See the trading journal template for a practical field structure. As history grows, an online journal saves time on statistics, filters and links between days, metrics and trades. A filled journal example shows how a single record can look.

Conclusion

Keep the journal detailed enough to reconstruct the decision and simple enough to use consistently. Record the same core facts, review series of trades, and convert repeated observations into rules you can test.
