Free shows what it would have done. Standard attempts to close the position.
Watch, the free plan, alerts you when your unattended strategy leaves a position without a stop, or loses its connection while a position is open, and says what Protect would have done. The Scan reports leftover orders afterwards. Paid plans add Protect: when a position still has no stop after a short wait, it attempts to close it and to cancel the orders left behind. You switch Protect on yourself, after its Learn report.

What Protect is built to do once you switch it on: it attempts to close a position that still has no stop after a short wait, using NinjaTrader’s own Close Position command through its order interface (ATI), with a screen-click fallback, 3 attempts in all, then alerts you that it needs a person; attempts to cancel leftover orders; attempts to restart NinjaTrader after a crash, and turns your strategy back on only when no position is open; attempts to switch off and close out at the end of the day; and adds a kill switch that switches the strategy off on command and an optional balance floor (it attempts to stop the strategy and close the position if the account falls below a level you set). It acts only on the account you configure.
Prices are planned monthly prices in US dollars and can change before StopWarden opens. Paid plans are planned to start with a 7-day trial that asks for a card.
On day one, a paid plan only alerts. Here is why.
Protect acts on your account, so it waits until StopWarden knows how your strategy places its stops. After about 20 trades over 5 sessions (in Watch, alerts only), it shows you a Learn report: how fast your stop goes in, and how often Protect would have acted with its short wait. Once you read and accept it, you can switch Protect on. If any of your strategy’s stops took too long to be working, the report says so and Protect stays off for that strategy. Some cases stay alerts-only in this version: ATM strategies (NinjaTrader’s Advanced Trade Management brackets), strategies that exit without a resting stop, strategies whose own stop is not reliably working inside the wait, and an account you also trade by hand and tell StopWarden so.
