People searching Google for trading journal usually want one clear answer: what it is, what to write down, and how it helps when spot trading habits no longer fit futures. A trading journal is a record of each trade, the reason for it, and what happened after entry. Its job is not to predict markets. Its job is to make your decisions visible.
For beginners, that means writing down:
- the setup you thought you saw
- the risk you chose
- the result you got
If you want to practice the habit without real funds, you can try it in the play-money terminal. ZK Futures is a testnet demo of a hybrid crypto exchange for perpetual futures, and a new account starts with 1,205.50 test USDT.
What a Trading Journal Actually Does
A trading journal turns each futures trade into a record you can inspect later instead of a story told from memory. In practice, it answers three questions: what position you opened, how much exposure you took on, and whether the risk matched the idea.
That matters in derivatives because position size and margin are not the same thing. Position value is the full USDT exposure of the contract, while margin is the smaller amount set aside to support it; if you want the math behind that exposure, see position value in USDT. A journal helps you keep those two numbers separate.
It also shows which margin model you used. Isolated margin means one position has its own dedicated margin, so a review is clearer when you note that choice from the start; for the broader comparison, see isolated margin and cross margin.
A useful journal entry should let you reconstruct the trade without guessing. That includes:
- the market traded
- the direction
- the position value in USDT
- the leverage and initial margin
- any funding paid or received
If you practice with play money, the same habit still works. You can compare the market list with what you chose to trade, check open positions in your play-money portfolio, and verify settlements in your play-money wallet. Used this way, a journal is less about outcome and more about making risk visible before the next trade.
What to Record for Every Futures Trade
A useful trading journal entry should let you rebuild the trade from start to finish without guessing. Keep one fixed template so your notes stay comparable.
Record these facts first:
- market
- long or short
- entry time
- entry price
- exit time
- exit price
- position value in USDT
- leverage
- initial margin in USDT
- result in USDT
Then add the context that explains how the trade behaved.
Write down the mark price at entry and at review. The mark price is the reference price used to value the position and check liquidation, not simply the last trade; this guide on how the mark price works explains why that matters.
Include the liquidation price in the same note. Liquidation happens when margin plus unrealized PnL falls to the maintenance margin, which is 0.5% of the position value at the mark price, and the loss is capped at the position's margin. For this demo, the long liquidation price is entry price x (1 - 1/leverage) / (1 - 0.005), and the short liquidation price is entry price x (1 + 1/leverage) / (1 + 0.005).
It also helps to record how you entered and exited. A stop order is an order that triggers when price reaches a chosen level. A limit price is the highest buy price or lowest sell price you accept. If you used either one, note the level you chose and whether the fill matched your plan.
Last, leave a line for funding. Funding is a periodic payment between longs and shorts in perpetual futures, covered in this funding rates guide. In ZK Futures, funding settles every 30 seconds in the demo, at most 0.1% of the position value per settlement.
How a Journal Helps You Manage Leverage, Liquidation, and Funding
Your trading journal should make one thing easy to see: how fast a futures position can break down when leverage is high. Leverage means controlling a larger position with a smaller amount of margin. In a linear, USDT-margined perpetual, a small move against you can consume that margin quickly.
The journal is where you test whether the size of the position made sense for the idea. A chart pattern may look the same at 2x, 10x, or 100x, but the risk is very different. With 10x leverage, a 10% adverse move uses up the initial margin. With 100x, a 1% move does. With 2x, a 50% move does. Writing this beside each trade helps you see when the position was too large for the room available.
It should also capture the path of the trade, not just the ending. Unrealized PnL is the profit or loss a position would have if closed at the current mark price. If that value swung sharply while you were still holding, the trade may have been harder to manage than your entry note suggests.
Add a short risk check to every review:
- position value in USDT
- margin locked at entry
- worst unrealized PnL reached
- distance from entry to liquidation
- number of funding settlements while open
- total funding paid or received
Funding deserves its own line because it can change the result even when price goes sideways. In the demo, funding settles every 30 seconds, with a cap of 0.1% of the position value per settlement. For example, a funding rate of 0.01% on a position worth 10,000 USDT is 1 USDT per settlement.
A Simple Review Process Beginners Can Repeat
People searching for a trading journal usually want a repeatable way to review trades, not a pile of notes they never use again. For futures beginners, the review should be short, structured, and focused on decisions you can measure.
Pick one session each week. Read your entries in order and score each trade by process first, result second. Process means whether you followed your own plan from entry to exit. This matters because a trade can end with a positive result in USDT and still show poor risk control.
Use five questions:
- Did I define the setup before entry?
- Did I record the position value in USDT and the initial margin?
- Did the leverage leave enough room before liquidation?
- Did I change the plan while the trade was open?
- Did funding affect the outcome more than I expected?
Next, separate mistakes into two groups: planning errors and execution errors. A planning error starts before entry, such as choosing leverage without noting how close liquidation would be. An execution error happens during the trade, such as moving the exit without writing down why.
Finish with a short weekly note in three lines:
- one repeated strength
- one repeated mistake
- one rule for next week

Practice the Habit With Play Money First
A trading journal is easier to build when each entry is only about process. In a demo setting, you can repeat the same routine, check what you recorded, and see whether your notes match what the position actually did.
For beginners, that matters because futures add moving parts that spot traders may not track yet. A perpetual future is a contract that stays open without an expiry date. Isolated margin means margin is assigned to one position only. Liquidation is the forced close that happens when position equity falls to the maintenance margin.
With play money, the goal is not the outcome. The goal is to practice recording risk clearly and consistently.
The terminal shows details you can record in your journal, such as:
- market
- long or short
- entry price
- mark price
- leverage from 1x to 100x
- unrealized PnL
- margin ratio
- liquidation price
- funding payments
You can also add manual notes beside those fields, such as why you entered, what would invalidate the idea, and whether the order book changed while the trade was open.
Common Questions About a Trading Journal
Is a trading journal just for winning and losing trades?
No. A trading journal is most useful when it shows how you made decisions, not only how a trade ended. Two trades can have the same result in USDT but very different risk. One may have respected your plan, while the other may have used too much leverage or left almost no room before liquidation.
A beginner journal is better when it records process, such as:
- what you expected
- what invalidated the idea
- what size you chose
- what changed after entry
That makes reviews more honest than memory alone.
How detailed should a beginner trading journal be?
Detailed enough to rebuild the trade, but short enough that you will actually keep doing it. If the format is too long, many traders stop after a few days.
A practical entry can fit in a few lines:
- market and direction
- entry and exit
- position value in USDT
- leverage and initial margin
- liquidation price
- funding paid or received
- one sentence for the idea
- one sentence for the exit
That is usually enough for a useful weekly review.
When should I write in my trading journal?
The best time is in three moments: before entry, during the trade if your plan changes, and right after exit. Writing before entry matters because it captures your reasoning before the result can distort it.
A short schedule works well:
- before entry: thesis and risk
- while open: changes in management
- after exit: result and lesson
Can I practice a trading journal without real money?
Yes. For beginners, play money can make the habit easier to learn because the focus stays on recording risk and behavior. ZK Futures is a testnet demo of a hybrid crypto exchange for perpetual futures, and every balance in it is play money. A new account starts with 1,205.50 test USDT with no monetary value.
Start Small, Stay Consistent
A trading journal matters because it turns vague impressions into specific notes you can review later. Instead of remembering that a trade felt rushed or uncomfortable, you can see exactly what happened and why.
In futures, the most useful notes are often the risk notes:
- leverage chosen
- margin committed
- liquidation distance
- funding paid or received
Keep the format simple. If your journal takes too long to fill in, you are less likely to use it after every trade.
Responsible practice means setting limits, reviewing mistakes honestly, and treating leverage with caution, because liquidation can happen quickly.
