Why You Need a Trading Journal

Updated October 23, 2026

Your platform already records every trade. A journal exists to record what the platform cannot: why you took the trade, what you expected, and what you were thinking when it went wrong. Updated September 2026.

What to record

• Date, instrument, direction and timeframe

• Entry price, stop loss and target, set before entry

• Position size and the percentage of account risked

• The specific setup or rule that triggered the trade

• What you expected to happen and why

• Your emotional state at entry and at exit

• The outcome, and whether you followed the plan or deviated

• A chart screenshot marked with your levels

The two columns that matter most are the reasoning and the followed-the-plan flag. Everything else is available in the platform history. Those two are not, and they are what make the record useful.

Why the platform history is not enough

The history tab shows entries, exits and profit or loss. It shows what happened.

It does not show that you widened the stop twice, that you entered because you were annoyed about the previous loss, or that the setup did not actually meet your criteria and you took it anyway. Those are the causes of most losing sequences, and none of them appear in the numbers.

Identifying patterns in losses

Losing streaks feel random from inside them. Reviewed across a written record, they usually are not.

Common patterns that emerge: losses concentrated in a particular instrument, a particular time of day, or trades taken immediately after a previous loss.

Another frequent finding is holding losers too long. A trader who cuts losses at the planned level and one who waits for a recovery can run the identical strategy with opposite results, and the journal is what makes that visible.

The point of the exercise is specificity. Knowing that you lose money is not actionable. Knowing that you lose money on trades taken within an hour of a previous loss is.

Reducing stress

Fear and greed are constant during an open position: should I close, should I add, is this the reversal.

A journal provides perspective. Looking back at recorded trades shows that drawdowns have occurred before and resolved, which is difficult to believe while inside one.

It also settles the question during a trade: if the plan was written down before entry, the current question has already been answered and does not need relitigating under pressure.

Building confidence

Confidence in a strategy comes from evidence, not from optimism. A record showing the approach worked across a sustained period, including losing runs, is what allows a trader to continue through the next one.

Without that record, every drawdown raises the question of whether the strategy has stopped working, and that question is usually answered by abandoning it at the worst moment.

How to keep one

A spreadsheet is sufficient. Dedicated journalling software exists and adds automation, but the format matters far less than the consistency.

• Be specific: record the exact setup and level, not a general impression

• Be honest: a journal recording only good decisions is worthless, and the entries you least want to write are the useful ones

• Save chart screenshots with your levels marked, they show what you saw at the time

• Keep separate records if you trade more than one system, mixed results hide which one works

• Write the entry at the time, not reconstructed at the end of the week

Honesty is the condition everything else depends on. A journal is the only place where writing down that you broke your own rule has no consequence, which is exactly why doing so is worth the discomfort.

How to review it

• Review after at least 30 trades, not after a bad day

• Separate losses that followed the plan from losses caused by deviating

• Look for concentrations: instrument, time of day, sequence position after a previous trade

• Check whether winners were closed early and losers held long

• Change one thing at a time, so the next review can attribute the difference

Trading journal: frequently asked questions

Why not just use the platform history?

It records what happened, not why. It does not show that you widened a stop, took a trade out of frustration, or entered a setup that did not meet your criteria.

What is a Trader's Diary?

What should I record?

Entry, stop, target and size, plus the setup that triggered the trade, what you expected, your emotional state, and whether you followed the plan.

What software should I use?

A spreadsheet is enough. Dedicated tools add automation, but consistency matters far more than the format.

Why Should You Start Keeping a Trader's Diary?

When should I review it?

After at least 30 trades. Reviewing after a bad day produces conclusions drawn from noise rather than from performance.

What patterns should I look for?

Concentrations of losses by instrument, time of day, or position in a sequence, plus whether winners are closed early and losers held too long.

Does a journal actually improve results?

It makes the causes of losses visible and specific. Knowing you lose money is not actionable, knowing which conditions produce the losses is.
