How to Keep a Trading Journal: A Step-by-Step Guide

To keep a trading journal, record every trade with its entry, exit, size, and the reason you took it, then review those records on a fixed schedule. The journal only works if you write honestly and consistently, so keep the format small enough that you will actually use it.
This guide walks through how to start a trading journal from nothing, what to write, how to build the habit, and how to avoid the mistakes that make most journals die within a month. It is education, not financial advice, and nothing here promises profit.
Why keep a trading journal at all
Your broker statement tells you what happened. A journal tells you why. Without the why, you can see that you lost money on Thursday but not that you broke your own rules after two quick losses.
A journal gives you three things:
- A record you can measure. Win rate, average win, average loss, and expectancy all need data. Memory is a poor data source because it keeps the exciting trades and drops the boring ones.
- A feedback loop. You can only fix a behavior you have noticed. Written notes make patterns visible.
- Accountability. If you know you must write down why you entered, you are less likely to enter on impulse.
Step 1: Pick one place to log trades
Choose a single home for your journal before you place another trade. Your options are a paper notebook, a spreadsheet, or dedicated software.
A notebook is fast and private but cannot calculate anything. A spreadsheet is flexible and free, though you maintain every formula yourself (see Excel vs trading journal software for the tradeoffs). Software handles the math and charts for you. If you want to compare tools, best trading journal software and free trading journal apps cover the field.
The best choice is the one you will open every day. Do not spend a week choosing. Start with something simple and move later if you outgrow it.
Step 2: Decide what to record for every trade
Keep the required fields short. Seven to ten is plenty at the start.
| Field | Why it matters |
|---|---|
| Date and time | Shows when you trade well or badly |
| Instrument | Stock, option, future, crypto pair, or forex pair |
| Direction | Long or short |
| Entry price and size | The base of every calculation |
| Stop and target | Proves you had a plan before entering |
| Exit price | Completes the record |
| Result | Profit or loss in currency, and in R if you use it |
| Setup name | Groups similar trades so you can compare them |
| Reason for entry | One or two sentences, written before or at entry |
| Emotion and rule check | Did you follow your plan? How did you feel? |
If you want the full field list as something you can copy, see the trading journal template.
R is simply your risk per trade as a unit. If you risked $100 and made $250, that trade was +2.5R. Using R lets you compare trades of different sizes.
Step 3: Write your plan before you enter
The most useful entry is the one you write before the trade, not after. Before you click buy or sell, note:
- What setup this is.
- Where you will enter.
- Where your stop goes, and how much that risks.
- Where you will take profit, or how you will trail.
- What would make you skip the trade.
This takes under a minute. It turns a hunch into a decision, and it gives you something to measure your execution against later.
Step 4: Log the result right after you exit
Record the exit while it is fresh. Waiting until the weekend means you will forget the details that matter most: where you moved a stop, whether you hesitated, and what you felt.
Write what actually happened, not what you wish had happened. If you exited early out of fear, say so. If you added to a loser, say so. The journal is for you. Nobody grades it.
Step 5: Add a short note on execution and emotion
A good note is two or three sentences. Answer these:
- Did I follow my plan? If not, where did I deviate?
- What was I feeling at entry and at exit?
- What is the one thing I would repeat or change?
Keep a consistent set of tags so you can filter later, for example "followed plan", "chased entry", "moved stop", "oversized", or "FOMO". Tags turn scattered notes into data. In Momentra, journal notes have a rich editor and tags, so you can write the story of a trade and filter by tag when you review.
Step 6: Review on a schedule
Writing entries is half the job. The other half is reading them. Set a weekly review, ideally 30 minutes, where you look at your results and your notes together. How to review your trades gives a repeatable routine you can copy.
Add a longer monthly check where you ask whether your strategy still shows an edge. Two numbers worth tracking here are expectancy and profit factor. See the trading expectancy formula and win rate vs profit factor for how to calculate them.
Step 7: Build the habit
Most journals fail because the habit fails, not because the format is wrong. A few things help:
- Tie it to something fixed. Log right after you close a position, or right after the market closes.
- Lower the bar on bad days. If you are tired or upset, write one line. A short entry beats a skipped day.
- Track the streak. A visible streak makes you less likely to break the chain. Momentra includes a daily journaling streak for this reason.
- Log the boring trades too. Winners and no-trade days matter as much as losers.
What a good journal tells you after a month
After 20 to 30 trades, you can start asking real questions. Which setup has the best average result? Which time of day do you lose most? How often do you break your rules, and what do those trades cost compared with the ones where you followed them?
Here is a simple example with made-up numbers. Suppose over a month you take 10 trades on one setup: 4 winners averaging $150 and 6 losers averaging $60.
- Total wins: 4 x $150 = $600
- Total losses: 6 x $60 = $360
- Net: $600 - $360 = $240
- Expectancy per trade: $240 / 10 = $24
A win rate of 40 percent looks poor, yet the setup is positive because winners are larger than losers. Without a journal you would likely judge it by the six losses. These figures are only an illustration, and a sample of 10 is far too small to trust.
Common mistakes to avoid
- Logging only wins or only losses. You need both to see the real picture.
- Skipping the reason. A record of prices without a reason teaches nothing.
- Over-engineering. A 40-field template is abandoned within a week.
- Never reviewing. Entries that are never read are just a diary.
- Judging by one trade. Judge process over many trades, not outcome on a single one.
- Journaling only after losses. That builds a record of pain, not a balanced view.
FAQ
How do I start a trading journal as a beginner?
Pick one tool, such as a notebook, spreadsheet, or journal app. Record the date, instrument, direction, entry, stop, exit, result, and one sentence on why you took the trade. Start today with your next trade rather than waiting for the perfect template.
What should I write in a trading journal?
Write the objective details (prices, size, result) and the subjective ones (your reason for entry, whether you followed your plan, and how you felt). The subjective notes are usually the more valuable half because they explain your behavior.
How often should I update my trading journal?
Log each trade as it happens, and review the whole journal once a week. Daily logging keeps details fresh, and the weekly review is where you spot patterns and decide what to change.
Is a trading journal worth it if I only trade a few times a week?
Yes. Fewer trades means each one carries more weight, and a record helps you judge them fairly. You will just take longer to build a sample large enough to draw conclusions.
Can I keep a trading journal for options, futures, or crypto?
Yes, the method is the same for any market. You add a few fields for the instrument, such as strike and expiry for options or contract size for futures. See the guides on an options trading journal and a futures trading journal.
Start small and stay consistent
A trading journal does not need to be elaborate. Record the plan, record the result, note how you behaved, and read it back every week. Do that for a couple of months and you will know your own trading better than any statement could tell you. This article is general education and not financial advice, and journaling does not guarantee better results.
