The main idea
A lot of trading journals become screenshot folders with random notes. They look productive, but they do not tell the trader what to fix.
A useful journal should show patterns. Not just whether you made money. It should show when you break rules, which setups you handle well, what time of day you trade best, and which emotions keep showing up before bad decisions.
What to look for
Your journal should answer these questions without you needing to guess:
- Which setup actually makes sense for you?
- What time of day causes the most mistakes?
- Do you lose more from bad entries or bad exits?
- Are your biggest losses planned losses or emotional losses?
- Do you follow the same lot-sizing rule every time?
Practical steps
Use this simple structure for each trade:
Before the trade
- Setup name.
- Reason for entry.
- Invalidation point.
- Planned risk.
- Emotional state from 1 to 5.
After the trade
- Did I follow the plan?
- What did I do well?
- What did I do poorly?
- Was the mistake technical, emotional, or risk-related?
- One rule to apply next time.
End of week
At the end of the week, do not read everything. Count patterns. How many trades were A-grade? How many were emotional? How many happened after your best window? That is where the useful information is.
Final note
A good journal should make it harder for you to lie to yourself. If it does not change your behavior, it is just paperwork.
The journal is not there to prove you worked hard. It is there to show you what keeps costing you money.
