Track what you doWhat you don’t track, you can’t improve.
Your balance and a vague feeling tell you almost nothing about your trading. Collect data on your own decisions with a simple log, and your strengths and weaknesses show up in writing.
Your balance tells you almost nothing
If you can’t say why your last winning trade worked, you can’t repeat it. If you can’t say why your last loser failed, you will probably lose that way again.
Most traders judge themselves by their account balance and a vague feeling about how the week went. That tells you almost nothing. A good week can hide a bad habit, and a bad week can hide a sound process.
A data-driven approach means you also collect data on yourself: every trade, why you took it, what the data said, how you managed it and how it ended. The journal lessons later in the course build on this simple start.
Measuring needs a consistent process
Tracking only works if you follow a consistent process, which means you make your decisions the same way every time. If every trade has a different kind of reason, a tip one day and a gut feeling the next, there is nothing to compare.
Only with a consistent process can you actually measure what you are doing. Then every row in your log is another test of the same approach, and the results start to mean something.
What to record
Start simple. A spreadsheet or the Trading Journal with 6 columns is enough: the date, the market, your reason, the data behind it, the result, and one line on what you would do differently next time.
The reason and the data columns matter most. They turn a list of results into a record of decisions, so you can later sort your trades by why you took them. The last column makes you draw a lesson while the trade is still fresh. Fill in a row after every trade, winners included, because they hold half the lessons, such as closing them far too early. Then read the whole sheet every week.
| Date | Market | Reason | Data behind it | Result | Next time |
|---|---|---|---|---|---|
| Mon | EUR/USD | Inflation trend | CPI above forecast | +0.8% | Hold to target |
| Thu | GBP/USD | Central bank speech | Speech tone only | −1% | Skip speech trades |
What the patterns reveal
Once you have a few weeks of rows, patterns show up. Maybe your trades based on inflation data work well, but the ones around central bank speeches keep going wrong. Maybe your entries are fine, but you close your winners far too early. Those are your strengths and weaknesses, and now they are written down instead of guessed.
Then you improve on purpose. You do more of what works, you fix or drop what doesn’t, and a few weeks later you check the numbers again to see if the change helped. It is the same try, review and adjust loop as in the lesson on asking better questions, run over many trades instead of one. That is how professionals get better: by measuring the approach they have, rather than finding a new strategy every week.
What you don’t track, you can’t improve.
In short
- Your balance and a vague feeling tell you almost nothing. Collect data on yourself: why you took each trade, what the data said, how you managed it and how it ended.
- Measuring only works with a consistent process. If every trade has a different kind of reason, there is nothing to compare.
- Review the log every week, do more of what works, fix or drop what doesn’t, and check again a few weeks later.
Questions
How many trades before the patterns mean anything?
A handful is too few to judge. Keep filling in the log and check it every week. A pattern that keeps repeating over several weeks is worth acting on.
Key terms
- Trading journal
- A record of every trade with the reason, the numbers and a review. The basis for improving with facts instead of feelings.
