Step 1
Start your free trial.
Create your account and start the 30-day free trial. A card is required at checkout, but $0 is charged today and you can cancel anytime during the trial — the same login activates the Windows app.

Your NinjaTrader credentials stay encrypted on your machine — never on our servers.
Step 2
Install the app.
Download the Windows app and run it on the computer or VPS that runs NinjaTrader. If Windows asks you to confirm an app downloaded from the internet, choose More info, then Run anyway. Setup takes under a minute, and Ninja Watchdog keeps itself updated after installation.
Step 3
Sign in and protect.
Open Ninja Watchdog, sign in, enter your NinjaTrader credentials if needed, and let the desktop app handle launch recovery, reconnects, strategy restore, repair, and alerts. Your NinjaTrader credentials are stored encrypted on your own machine and are never sent to our servers.
