The buy-once trading journal

Anvil finds the repeatable mistakes bleeding your account — in real dollars — and tells you exactly what to fix. One payment. Runs on your machine. Your data never leaves your device.

No account. No cloud. No subscription. · 30-day money-back guarantee.

A journal shouldn't be rent

Own it once. Not $348 a year, forever.

The category leader rents you your own trading history for ~$29–49/month. Stop paying, lose access. Anvil is one payment — and it works offline, so your P&L never sits on someone else's server.

The killer feature

Most journals tell you what happened. Anvil tells you what to fix.

The Leak Finder reads your trades and surfaces the repeatable habits costing you money — each one quantified in real dollars, each with a one-line fix. Then it shows the counterfactual: cut your biggest leak, and here's the account you could have.

REVENGE TRADING → After any loss, step away 15 minutes.
OVERTRADING → Cap the day at 4 trades and stop.
WORST SETUP → Pull it from live until you've proven it.

For funded traders

Keep your funded account alive.

Blowing an evaluation on a rule you didn't see coming is the prop trader's nightmare. Enter your account's rules — daily loss limit, trailing drawdown, profit target, consistency — and the Guardian tracks them from your logged trades and warns you as you approach a limit. Works with any funded-account program.

Everything you'd expect — done right

A full journal, not a gimmick.

Anvil Score

One number, 0–100, grading you across six skills — win rate, profit factor, win/loss, consistency, risk management and discipline. A single figure to chase and screenshot.

Plus: equity curve, P&L calendar heatmap, playbook with per-setup performance, deep reports by day, time and symbol, a psychology tracker, and a frictionless 5-second trade entry.

Questions

Good to know

Is my trading data really private?
Yes — and it's not just a promise. Anvil has no backend and makes zero network requests; a strict security policy blocks the app from connecting anywhere. Your journal is stored only on your own device. Back it up whenever you like with a one-click export.
Do I need to create an account?
No. There's no signup, no login, no cloud. You buy it, download it, and it runs. That's the whole point.
How do trades get in? Can I import from my broker?
Log a trade in about five seconds (symbol, side, P&L), or import a CSV export from your platform. Common columns — date, symbol, side, quantity, P&L, fees — are auto-detected by name, so common exports usually import with no cleanup; if a column isn't recognized, rename its header and re-import. No account linking, nothing leaves your device.
Is it really buy-once, or a trial?
Buy-once. One payment and it's yours — no subscription, no renewal, no feature paywall. Updates and patches for v2 are included.
Windows or Mac?
Windows today, as a proper installer. A macOS build is on the roadmap. Try the live demo in any browser first to see the whole thing.
What if it's not for me?
30-day money-back guarantee, no questions. If Anvil doesn't help you trade better, you get a full refund.
