Key takeaways
- A journal full of outcomes records what the market did, not what you did.
- Log, per trade, whether your conditions were present, what state you were in, and whether you followed your exit.
- Single trades tell you little. Across twenty trades, where you systematically drift becomes visible.
- A weekly review on execution shows you which pattern is costing you money, even in a winning week.
Most traders eventually start keeping a trading journal. They log entry, exit, result, and paste in a screenshot. Two months in, there's a tidy file with a hundred rows in it, and reading it back produces no usable conclusion at all.
That's because a file like that only contains outcomes. Your broker already keeps those. You can't tell from a string of outcomes which decision was actually good: a bad trade can win and a correct one can lose, so optimizing for outcome teaches you exactly the wrong lesson.
A journal becomes useful once it records your decisions instead. Below is which fields that means, how to fill them in without turning it into a chore, and what to look for in your weekly review.
Why an outcome journal teaches you nothing
Say you take a trade that didn't meet your conditions, and it still returns 2R. In an outcome journal, that trade shows up green, sitting between all the other green rows. Nothing flags that you should never have taken it, and the odds you repeat it just went up.
The reverse happens too. A trade where you did everything right and it loses comes in red. If you optimize for color, you'll unlearn your best behavior simply because it hit a losing stretch. That's a journal working against you instead of for you.
What you need is a split between the quality of your decision and its outcome. Only the first is within your control, so only the first is worth tracking. That's also why understanding the mistake isn't enough: without a record of your state, you miss the trigger, and without the trigger, you miss the repeat.
What to actually write down per trade
Keep it small enough that you'll still be doing it in a month. Five fields per trade is enough, as long as they're the right five.
| Moment | What you record | Why this field matters |
|---|---|---|
| Before entry | Which conditions were present, checked off | Confirms afterward whether this was actually a valid setup |
| Before entry | Your state: calm, rushed, trying to make something right | Connects deviations to their trigger |
| During the trade | Any change to your stop or target, with the reason | This is where most of your edge leaks out |
| After the exit | Exit followed the plan, yes or no | Separates execution from outcome |
| End of day | Number of trades taken without valid conditions | The earliest signal that you're starting to drift |
The state field is the one most traders skip, and it's the only one that explains why a good week suddenly turns. One word is enough. You don't need to analyze it in the moment, just capture it so you can line it up against your deviations later.
What to look for in your weekly review
A single trade carries too much noise to learn from. Across twenty trades the pattern shows up on its own, and it's usually just one. Read back in this order:
- How many trades met all your conditions? That number is your actual score for the week, independent of what you made or lost.
- What state shows up on the trades that didn't qualify? Almost always one word surfaces: rushed, bored, or trying to fix something.
- Where did stops get moved? Check whether it happened on the same type of trade or around the same time of day.
- What happened after a loss? Count how many trades followed within an hour of one. That's your clearest signal for overtrading.
Notice that none of these questions are about the market. That's deliberate. Your journal is the one instrument that measures your side of the transaction.
| Outcome journal | Decision journal | |
|---|---|---|
| What's in it | Entry, exit, result | Conditions, state, deviations |
| What you learn from it | What the market did | What you did and why |
| After a winning week | Everything looks fine | You see which wins you didn't actually earn |
| After a losing week | You start doubting your strategy | You see whether it was execution or variance |
| Time per day | Two minutes | Five minutes |
Why this works if you keep at it
At MTA we use the journal as the measurement tool for performance conditioning. You're training the space between what you feel and what you do, and that's exactly what the state and deviation fields make visible. That's the core skill from the Operator Model, and it's measurable without ever looking at your PnL.
What usually surfaces by month two is one recurring pattern under pressure. One trader enters too early, another waits until the setup is gone. Those are opposite deviations that need opposite structure, and your journal is the fastest way to see which one is driving you.
Frequently asked questions
What is a trading journal?
A trading journal is a running record of your trades that captures how you arrived at each decision. It's different from your broker history, which only logs what happened. A journal records what you did and why, so you can find patterns in your own behavior, not just in the market.
What should you write in a trading journal?
Three things per trade: which conditions were present before you entered, what state you were in, and whether you followed your planned exit. Add, once a day, how many entries you took without your conditions actually being present. A screenshot helps, but without those fields it's just a collection of pictures.
How often should you review your trading journal?
Log briefly every day, and review it together once a week. A single trade is mostly noise; across twenty trades you can see where you systematically drift. In that weekly review, judge your execution, not your result: how many trades met your conditions, and what triggered the rest.
