How to keep a position journal and review yourself
This is the single most worthwhile habit I've found: two minutes a day, writing down the reason and the mood behind each buy and sell. It won't predict the market. It helps you see something more important clearly, yourself.
I'll admit it: I started keeping a position journal because I got beaten into it. For my first couple of years I kept thinking I was "off lately" or "running unlucky these days," chalked losses up to mysticism, turned the page, and went again next time. Then one time I forced myself to write down every buy and sell from the past six months, one by one, and got a hard jolt. It turned out I wasn't unlucky, I'd made the same mistake seven or eight times: the moment a market got hot and a chat lit up, I couldn't resist chasing in. That truth, I'd never have seen on "memory" alone. It took black ink on white paper to force me to admit it.
This piece is about how to keep that journal. It's simple, simple enough that you might doubt "what good is this." But trust me, it's the highest-return method I've tried, two minutes a day for a mirror that shows you clearly. As usual, the backdrop first: crypto is extremely volatile, losing all of your capital is possible, only spare money, your own decisions, and this isn't investment advice.
Why keep it: turn "feelings" into facts
People who don't journal review from memory. But memory is wildly unreliable. It quietly beautifies, recording "I actually panicked and bought rashly" as "I judged it well, the market just didn't cooperate." The human brain is built to rationalise its own decisions, especially the losing ones. So you think you're reviewing, when really you're just writing your past self a nicer-sounding story.
Why it works People unconsciously alter the memory of their own decisions, and losing decisions are especially easy to "rationalise." The reason and emotion you write down in the moment are unbeautified raw evidence, which is exactly the journal's biggest value.
What a position journal does is nail it down as fact before memory gets altered. What you were thinking at the moment of buying, how you felt, written down on the spot. When you look back days later, you'll often find that the self at the time and the self in your memory are two different people. That gap is the entire space you have to improve in. Turning the vague "I feel off lately" into the concrete "I got caught chasing a hot coin for the third time," only the latter can be changed.
What to record: reasons and emotions, not profit and loss
This is the most important sentence in the whole piece, and I want to pull it out on its own: the core of a position journal isn't profit and loss, it's reasons and emotions.
Term Position journal / trading journal: a trade-by-trade record of your buy and sell decisions, where the point isn't bookkeeping (the exchange already has the profit and loss) but writing down "why I did it, how I felt, and whether it looks right afterwards." It serves reviewing and improving yourself, not tax filing or reconciliation.
How much you made or lost is written clearly in your exchange account, no need to copy it. And reviewing by staring at profit and loss leads you astray, a winning trade may have been pure luck on direction; a losing trade's reasoning and method may have been entirely sound, the luck just wasn't on your side this time. If you only look at the result, you'll repeat what you got lucky on as if it were skill, and throw away what you did right as if it were a mistake. Results can lie. Reasons can't.
Careful Logging only profit and loss, not reasons, is the most common fake review. It makes you believe "a win means I was right, a loss means I was wrong," so everything you learn is the wrong lesson, rewarding luck and punishing what was correct. Recording the reason is what separates luck from skill.
So for each buy and sell, record three things. First, the reason for the trade, why did you make this decision at this time, this price? Was it planned, or a spur-of-the-moment move? Second, the emotion at the time, were you calm, or greedy, panicked, unwilling to let go? Emotion is often the real puppeteer. Third, days later, fill in the hindsight, looking back now, does the reason hold? Were you right, or just lucky? How should you fix it next time? Record all three and your journal has a soul.
A table you can copy straight in
Don't overthink it, a table is enough. The one below you can copy straight into a memo or spreadsheet; the fields don't have to be word for word, add or trim to your habits. For each buy or sell, fill one row.
| Field | What to record | Example (hypothetical) |
|---|---|---|
| Date | the day you placed the order | May 16 |
| Buy/Sell | was this a buy or a sell | Buy |
| Price | fill price | about $100 |
| Position | what share of the account | about 5% |
| Stop | where you'd admit you're wrong and exit | $90 |
| Reason | why at this time, this price | back to the planned support |
| Emotion | calm, or anxious / greedy | a bit afraid to miss it |
| Hindsight | fill days later: right or wrong, how to fix | reason held but motive was fear of missing |
The few numbers in the table (price, position, stop) are hypothetical examples, purely to show the format, not any advice. You'll notice the "price," "position," and "stop" columns are exactly the inputs to the method in position sizing. Journaling and managing your position are really two sides of one thing: before the order, use them to work out how much to buy; after the order, record them into the journal to review.
Where this comes from The price, position, and stop in the table (about $100, about 5%, $90) are invented to illustrate the format, not the real data of any specific asset, and not advice to buy this way. What you should actually fill in is your own real fill record for each trade.
A small tip
For the "hindsight" column, I'd suggest filling it three to five days, even a week or two, later, not the same day. With some time in between, the emotion has faded, and only then can you see clearly whether judgement was in charge at the time, or emotion.
How to review: find the habit that keeps biting you
Recording is only the first step; reviewing is where the journal really delivers. My suggestion is to spread out the records every so often, say once a month, not look at how much you made, and specifically hunt for recurring patterns.
You'll be surprised how "consistent" you are. Maybe in six of your ten losses, the "emotion" column reads "afraid to miss"; or maybe every time you moved a stop, the result got worse. These patterns are invisible in any single trade and only surface when a string of them is laid out. Find the habit that keeps biting you, and just watch it for a month, this beats reading ten technique articles, because what you're fixing is yourself, not some external technique. This is exactly what the seventh item, "never reviewing," in the seven money-losing moves beginners make is getting at: losing isn't the scary part, the scary part is losing and seeing nothing clearly.
In the end, a position journal isn't some advanced tool, it's a mirror. You can't control the market, you can't control what others shout, and the only thing you can control, and most should, is the person in the mirror making decision after decision. See him clearly, and you genuinely start to improve. Take it slow, and learn not to lose first. Next, I'd suggest reading how much to put in first, then opening the tools to work out your next trade's price, position, and stop, which happen to be the first row your journal needs.
Risk note
This article is a personal account, not investment advice, and it recommends no specific asset or action. Crypto is extremely volatile, and losing all of your capital is possible. Whether to take part, how much to put in, when to enter or exit, are all yours to judge and yours alone to bear. All numbers in the table (such as "about $100," "about 5%," "stop $90") are hypothetical examples for illustrating the format, representing no advice or prediction.
To journal, you first need an account that shows your fills clearly
Keeping a position journal needs a proper platform that lets you see every fill price, fee, and open order. I use Binance myself: solid spot depth, with order and fill history laid out clearly, which makes filling the journal against it easy. Registering with referral code BNB2301 gets you a fee discount, and when you're journaling you'll find the fees you save add up too.
