The best trading journal app is the one you’ll actually fill in after every trade, and that shows you what to fix, not just what happened. Look for easy trade imports, setup tags, review prompts, stats by setup and time, and a way to see your habits. Popular journals differ mainly in how much they automate, how deep the analytics go, and whether they coach you. If you’re unsure, start with a spreadsheet, then move to an app when you’re spending more time logging than reviewing.
What a trading journal app should do
| Feature | Why it matters |
|---|---|
| Imports from your broker | Saves time and avoids typos |
| Pre-trade plan | Records entry, stop and target before you click, so you can compare plan vs execution |
| Tags for setups and mistakes | Lets you see which setups pay and which mistakes cost |
| Stats | Win rate, average win and loss, profit factor, expectancy, by setup and time of day |
| Screenshots and notes | Context for review |
| Review prompts | Turns logging into learning |
| Habit tracking or coaching | Points to the behavior behind the numbers |
How popular journals differ
| Journal | Known for | Worth knowing |
|---|---|---|
| TraderSync | Broad broker imports, analytics, AI features | Paid plans |
| Tradervue | Long-running web journal, sharing trades | Has a limited free plan |
| Edgewonk | Deep analytics and psychology tracking | Paid |
| TradesViz | Large range of charts and stats | Has a free tier |
| Nummius | Journal tied to plans, charts, AI coaching and a practice arena | Free Duelist plan; Core adds imports and Deep Dive analytics |

Spreadsheet vs app
A spreadsheet is free and flexible. It works well when you’re starting out or trade a few times a week. Our guide to keeping a trading journal includes a free template.
An app saves time on imports and stats, and makes review easier with charts, tags and filters. It’s worth it when you trade often or want deeper analysis.
Which journal fits which trader
- Beginner: a simple journal with plans and reviews. Free is fine.
- Active day trader: fast broker imports and time-of-day stats.
- Swing trader: good screenshot and note support, plus setup tags.
- Trader working on discipline: review prompts and habit tracking.
How Nummius approaches the journal
The Nummius journal is built around one idea: trade the plan, fix the habit.
- Plan it: entry, stop and target, locked before you click.
- Take it: only when the checklist is complete.
- Review it: eight quick steps, graded on judgement, not P&L.
- See yourself: a habits hexagon shows six habits and names your weak spot.
- Fix one thing: Plutus, the AI coach, turns a bad day into one focus to hold for seven days.
- One place: your practice duels in the Arena get the same review as live trades.
The free Duelist plan includes the journal, plans and reviews, the habits view and a Trading Score. Core adds broker imports, Deep Dive analytics and unlimited coaching, with a 14-day free trial. See pricing.
Key takeaways
- The best journal is the one you’ll use after every trade.
- Plans, tags, stats and review prompts matter more than chart count.
- Start with a spreadsheet if you’re new; move to an app as you trade more.
- Choose a journal that points to habits, not just results. See how to stop overtrading.
Frequently asked questions
What is the best free trading journal?
A spreadsheet is the simplest free option. Several apps also have free plans, including Nummius’s Duelist plan with plans, reviews and a habits view.
Is a trading journal app worth paying for?
If you trade often, imports and analytics save time and show patterns you’d miss in a spreadsheet. If you trade rarely, a free option is enough.
What should a trading journal track?
The plan (entry, stop, target, reason), the execution, the result in R, the setup, mistakes, and how you felt. Review weekly.
