1. It should match your platform’s numbers
A journal you can’t trust is a journal you stop opening. Your net P&L should match your platform to the cent, fees included, and partial exits and adds should produce the same average price your platform shows.
Check how it handles commission per contract, slippage, and what happens when a number is off: can you correct it without breaking your statistics?
2. It should know prop firm rules
If you trade evaluations and funded accounts, a generic journal leaves the hardest part to you: trailing drawdown, daily loss, consistency, minimum days and payout conditions. Look for rules per account, with presets you can edit, and a clear view of what’s missing before your next payout.
Copy trading matters too: one decision on five accounts should count as one trade in your statistics, not five.
3. Logging has to take seconds
The best journal is the one you actually fill in. Importing a file, pasting a screenshot or typing a trade by hand should all be fast, and the discipline questions should sit on the same screen, while the trade is still fresh.
4. It should reward process, not profit
A day’s P&L is partly luck. What you control is the plan before the open, following your rules, and the review after the close. A journal that measures and rewards those habits keeps you consistent on the days the market doesn’t cooperate.
5. Your data stays yours
You should be able to export everything in a usable format and delete your account yourself. Social features, if any, should be opt-in and never show your P&L.
A quick checklist
Same numbers as my platform · rules per prop account · payout conditions · copy trading counted once · a trade logged in seconds · discipline on the same screen · a daily routine · full export · free to try without a card.
