What a Trading Journal Is
A trading journal is a record of your trades and the decisions that surrounded them.
It is not simply a list of profits and losses.
Trader Tools includes its own Trading Journal, designed to help you review losing trades, record what happened, identify repeated mistakes and improve future decisions.
A broader trading journal can record both winning and losing trades; the Trader Tools Journal is deliberately focused on reviewing losses, rule breaks and repeated mistakes
You can use the Trader Tools Trading Journal to record:
- loss amount
- trading session
- trade date and time
- the reason for the loss
- what you should avoid next time
- whether you followed your trading rules
Your previous journal entries can then be reviewed later, helping you spot patterns in your behaviour that may be difficult to notice from memory alone.
A useful journal helps you understand:
- why you entered a trade
- how much you risked
- whether you followed your rules
- what went wrong
- what you did well
- which mistakes keep repeating
- what you should change next time
The purpose is to turn past trades into information that can improve future decisions.
A trader may forget exactly why a trade was taken a few days later. A journal creates a permanent record that can be reviewed without relying on memory.
Key Takeaway
A trading journal helps you learn from what actually happened rather than from what you remember happening.
Why Review Losing Trades?
- Losing trades often reveal useful information
- A loss does not automatically mean the trade was bad
- Repeated mistakes become easier to identify
- Good losses and bad losses should be separated
Not every losing trade is a mistake.
You can follow your plan perfectly, manage risk correctly and still lose.
That may simply be a well-executed losing trade.
A more important problem is a loss caused by something such as:
- entering without a setup
- chasing price
- ignoring the Stop Loss
- risking too much
- trading outside your planned session
- revenge trading
- entering because of FOMO
Reviewing losses helps separate normal trading losses from avoidable mistakes.
Key Takeaway
The question is not only “Did I lose?” — it is “Why did I lose?”
What to Record
A useful journal can include:
- trade date and time
- market traded
- trading session
- Buy or Sell
- amount lost
- reason for entering
- reason the trade failed
- whether your rules were followed
- what you should avoid next time
- any useful notes about your decision-making
The journal does not need to become complicated.
Recording a small number of useful details consistently is often more valuable than collecting dozens of statistics you never review.
Key Takeaway
Record information that can help you make a better decision next time.
Did You Follow Your Rules?
- A losing trade can still follow the plan
- A winning trade can still break the rules
- Rule adherence should be reviewed separately from profit or loss
- Repeated rule breaks deserve attention
Imagine two trades.
Trade A
You followed your setup, used the correct risk, placed the Stop Loss correctly and the trade lost.
Trade B
You entered impulsively, ignored your risk rules and made a profit.
Trade B made money, but it may have reinforced poor behaviour.
This is why a journal should ask:
Did you follow your rules?
Over time, this can show whether your performance problems come from the strategy itself or from failing to execute it consistently.
Key Takeaway
Judge the quality of the decision separately from the financial result.
Record the Reason for the Loss
- Be specific
- Avoid vague explanations
- Separate market outcomes from trader mistakes
- Use consistent descriptions where possible
Writing:
“Bad trade”
does not tell you much.
A more useful explanation might be:
Entered too late after price had already moved.
Or:
Setup was valid, Stop Loss was reached normally.
Or:
Traded during a session I normally avoid.
Specific descriptions make repeated patterns much easier to recognise.
Key Takeaway
A useful journal explains what happened clearly enough that your future self can understand it.
What Should You Avoid Next Time?
Every reviewed mistake should ideally produce a simple lesson.
For example:
Problem: Chased price after missing the entry.
Next time: If the planned entry is missed, wait for another setup.
Or:
Problem: Increased position size after a previous loss.
Next time: Keep normal risk regardless of the previous trade.
This turns journaling into something practical.
The goal is not simply to document mistakes.
The goal is to reduce the chance of repeating them.
Key Takeaway
Every avoidable loss should teach you something you can apply to a future trade.
Look for Repeated Patterns
- One mistake may be random
- Repeated mistakes deserve attention
- Patterns can appear across sessions, setups or emotions
- Several weeks of data can reveal things memory cannot
After recording enough trades, you may begin to notice patterns.
For example:
- most rule breaks happen after a loss
- London trades perform better than late-session trades
- FOMO entries regularly lose
- oversized positions create emotional decisions
- trades taken while tired perform poorly
- one particular setup produces repeated losses
This is where a trading journal becomes especially valuable.
You are no longer looking at one trade.
You are looking at your behaviour across many trades.
Key Takeaway
Individual trades tell stories. Repeated trades reveal patterns.
Review Your Trading Sessions
- Record which session the trade occurred in
- Compare performance across sessions
- Look for repeated mistakes at certain times
- Avoid assuming every session suits your trading style
A trader may discover that their performance differs considerably depending on when they trade.
For example, they might consistently follow their plan during London but take more impulsive trades later in the day.
Another trader may perform better during New York.
The journal gives you evidence rather than relying on impressions.
Key Takeaway
Knowing when you trade well can be just as useful as knowing what you trade well.
Review Emotional Decisions
- Fear
- FOMO
- Greed
- Frustration
- Revenge trading
- Overconfidence
The previous lesson introduced trading psychology.
Your journal gives you a way to measure it.
For example, you might record:
Reason for loss: Entered immediately after losing the previous trade.
What to avoid: Wait until another valid setup appears.
If this happens repeatedly, revenge trading is no longer just something you think you might do.
You now have evidence that it is affecting your results.
Key Takeaway
A journal can turn emotional behaviour into something visible and measurable.
Screenshots and Chart Review
- A chart screenshot can preserve the setup
- Marking Entry, Stop Loss and Take Profit can help
- Compare what you saw then with what you see later
- Avoid judging the trade only with hindsight
Saving a chart image can make later review much easier.
It can show:
- the setup before entry
- where your Entry was placed
- where the Stop Loss was
- where the target was
- what market structure looked like
- what happened afterwards
However, reviewing a finished chart can make everything appear obvious.
This is known as hindsight bias.
Remember that when the trade was taken, the future candles did not yet exist.
Key Takeaway
Review what was knowable when you entered, not what became obvious afterwards.
Weekly and Monthly Reviews
- Review more than individual trades
- Count repeated mistakes
- Compare rule-following
- Identify areas that are improving
- Set one or two practical goals
A weekly review might reveal:
12 losing trades reviewed
3 rule breaks
Most common mistake: Late entry
The next week’s goal could therefore be:
Do not enter after the planned entry area has already been missed.
A monthly review can then show whether that behaviour improved.
This creates a feedback loop:
Trade → Record → Review → Identify → Improve
Key Takeaway
The value of a journal comes from reviewing it, not simply filling it in.
Personal Live Accounts and Prop Firm Accounts
- Journaling benefits both
- Account rules can provide additional information to review
- Prop traders should record decisions that move them towards account limits
- Personal traders can monitor damage to their own capital
On a personal live account, repeated mistakes directly affect your own money.
On a prop firm account, the same mistake may also bring the account closer to restrictions such as daily or maximum-loss limits.
Useful questions for a prop trader may include:
- Did this trade unnecessarily use too much of today’s risk?
- Was I trading because I felt pressure to reach a target?
- Did I continue trading after several losses?
- Did the trade follow both my rules and the firm’s rules?
The underlying purpose remains the same.
Understand your behaviour and improve it.
Key Takeaway
The account may be different, but disciplined review remains valuable.
Do Not Change Everything After One Trade
- One loss proves very little
- One win proves very little
- Look for repeated evidence
- Make changes deliberately
A trader may lose one trade and immediately decide:
My strategy no longer works.
They change the setup.
The next trade loses, so they change it again.
Eventually, they have no consistent strategy left to evaluate.
A journal helps prevent this by encouraging review across a meaningful sample of trades.
If the same problem appears repeatedly, then it may deserve attention.
Key Takeaway
Improve your trading from patterns, not from emotional reactions to one result.
Relevant Trader Tool
Trading Journal
The Trader Tools Trading Journal is designed to help you review losing trades and identify repeated mistakes.
You can record:
- loss amount
- trading session
- date and time
- reason for the loss
- what you should avoid next time
- whether you followed your rules
Your previous journal entries can then be reviewed to help identify patterns in your trading behaviour.
Common Journaling Mistakes
- Only recording winning trades
- Recording trades but never reviewing them
- Writing vague explanations
- Blaming every loss on the market
- Changing strategy after one result
- Hiding rule breaks from yourself
- Making the journal unnecessarily complicated
- Focusing only on money rather than decision quality
A trading journal only becomes useful when the information inside it is accurate.
There is little value in keeping a journal if important mistakes are deliberately ignored.
Key Takeaway
Your journal is most useful when it records what actually happened, including the mistakes.
Journaling & Trade Review — Key Takeaways
You should now understand that:
- a trading journal records more than profit and loss
- losing trades can contain valuable lessons
- a loss does not automatically mean a bad decision
- winning trades can still contain poor decisions
- rule adherence should be measured
- repeated mistakes are more important than isolated ones
- session performance can be compared
- emotional behaviour can be tracked
- screenshots can help preserve the original setup
- regular reviews can reveal patterns
- changes should be based on evidence rather than individual results
- journaling can benefit both personal and prop firm traders
Remember
The purpose of a trading journal is not to prove that you were right or wrong. It is to understand what happened and make the next decision better.
