A trading journal that keeps your data on your own PC

TradingDiary Pro is a Windows desktop trading journal that stores all of your trades, positions, notes and tags in a local database file on your computer. Nothing is uploaded to a cloud service – only a hardware ID is sent to the license server. It works offline, imports from 30+ brokers, and costs $149 once instead of a monthly subscription.

  • Private by design

    Broker statements contain account numbers, positions and your full PnL history. With a local journal that data never sits on someone else's server.

  • Works offline

    Review trades, add notes and run every report without an internet connection – on a plane, on a laptop, anywhere.

  • No subscription required

    $149 once, including 1 year of upgrades. After that the software keeps working; renewing upgrades for $49/year is optional.

  • No limits

    Unlimited trades, accounts and databases. Years of history stay fast because nothing has to travel over the network.

  • No lock-in

    Your journal is a file you own. If a vendor changes prices or shuts down a cloud service, your data is still on your disk.

  • Backups you control

    Copy one folder to back up or move your journal – to an external drive, your own cloud folder or a new PC.

How TradingDiary Pro stores your data

Each journal (TradingDiary Pro calls it a database) is a single file. By default it lives in Documents\TradingDiary Pro, and you can create as many databases as you like – for example one per broker, per strategy or per tax year. Inside a database you can keep any number of trading accounts and trades.

Because the database engine needs exclusive access to the file, keep it on a local drive rather than a network share. To back up your journal, copy the folder. To move to a new PC, copy the folder to the same place on the new machine and open the database from the File menu.

What still connects to the internet – and when

  • License validation: the software periodically sends your PC's hardware ID to the license server. After 5 days without a successful check it switches to read-only mode until it can connect again. No e-mail address is needed for the trial.
  • Broker imports you choose to run: file-based imports (CSV, Excel, Flex XML statements) work fully offline; web-service imports such as the Interactive Brokers Flex web service connect to your broker when you start them.
  • Historical price downloads you choose to run: quote download modules (for example Interactive Brokers, OANDA or Yahoo Finance) fetch prices for charts and net asset value reports.
  • AI assistants, only if you enable them: the built-in MCP server listens only on your own PC, is read-only and token protected; an assistant such as Claude receives just the data needed to answer the question you ask.

What you get in a local journal

Being local doesn't mean being basic. TradingDiary Pro imports from 30+ brokers, recognizes 25+ option strategies, and produces MAE/MFE, Sharpe ratio, risk, net asset value and country-specific tax reports. See all features.

Frequently asked questions

Does TradingDiary Pro upload my trades to the cloud?

No. The desktop application stores your trades, positions, notes and tags in a local database file on your PC. Only your PC's hardware ID is sent to the license server to validate the license.

Can I use TradingDiary Pro completely offline?

Yes. All journaling and reports work offline. The license is validated periodically; after 5 days without a successful validation the software switches to read-only mode until it can connect again.

How do I back up my trading journal?

Copy the TradingDiary Pro folder (by default Documents\TradingDiary Pro) to an external drive or your own cloud folder. Each database is a single file, so a backup is a simple file copy.

Is there a version for Mac or Linux?

The local desktop application runs on Windows 10 and 11. The browser-based web version (beta) runs on macOS and Linux too, but it stores your data in your own online account rather than on your PC.

Do I have to pay every month?

No. TradingDiary Pro is a $149 one-time license that includes 1 year of upgrades and support. After that you can keep using it; renewing upgrades for $49 per year is optional.
