The problem, in detail
A freeze with open positions means losing control of your risk
When NinjaTrader stops responding, the candles stop and the buttons do not react — but the market keeps moving and your position stays open. And the platform itself cannot warn you: the thread that froze is the one that would have to raise the alert.
What's at stake
Finding out in time costs less than a trapped position
If NinjaTrader freezes and you are not at the screen, you find out too late — with the position open, at the mercy of the market.
$0.33 a day for an external watcher that alerts your phone and restarts the platform. The first one it prevents has already paid for it.

Frequently asked questions
What people ask before buying
How does it detect the freeze if the platform is locked up?
Because it is an independent program that watches NinjaTrader from outside. It does not depend on the thread that locks up, so it keeps working when the platform stops responding.
Can it close my positions automatically?
It can react according to what you configure, including restarting NinjaTrader. You decide what it should do when there is a freeze.
Is it a NinjaTrader indicator?
No. It is an external Windows program that lives alongside NinjaTrader 8 and watches it from outside; that is why it stays active even if the platform freezes.
Does it alert me even when I am away from the computer?
Yes. It can alert your phone instantly, so you find out about a freeze even when you are away from the screen.
How do I try it and how do I buy?
Full 14-day demo, no card. The license is $119/year. The demo expires on its own, no charges.
