When NinjaTrader dies at 3 a.m., Ninja Watchdog brings it back.

Automatic crash, reboot, and Rithmic/Tradovate disconnect recovery for NinjaTrader 8

A VPS reboot or a 90-second Rithmic drop is all it takes: NinjaTrader closes, your strategy comes back disabled, and nobody is managing the position. Ninja Watchdog reopens the platform, reconnects the account, re-enables the exact strategies that were running, and emails you what happened.

How recovery works

NinjaTrader will not relaunch itself after a crash or reboot, and it will not re-enable a strategy a disconnect disabled. Ninja Watchdog runs beside NinjaTrader on the same Windows machine and does what you would do at the keyboard — automatically.

  1. 01

    Detects the failure

    Watches the NinjaTrader process, your broker and data-feed connections, and the enabled state of every strategy — locally and from our cloud, which emails you even if the whole machine goes silent.

  2. 02

    Relaunches and signs in

    If NinjaTrader crashed or the machine rebooted, Ninja Watchdog reopens the platform and signs it back in.

  3. 03

    Reconnects your accounts

    Restores the Rithmic, Tradovate, or other connections that were active before the interruption — and waits for live data.

  4. 04

    Re-enables your strategies

    Only after the platform is open, connected, and ready, it re-enables the exact strategies that were running — then emails you a recovery report of what happened and what it did.

What Ninja Watchdog never does

It restores your setup. Your strategy keeps making every trading decision.

Every way NinjaTrader goes down, handled automatically

Crashes, Windows-update reboots, Rithmic and Tradovate drops, disabled strategies, database problems — detected and fixed without you logging in.

01

Rithmic and Tradovate reconnects

Automatically reconnect NinjaTrader broker and data-feed connections, including Rithmic, Tradovate, NinjaTrader Brokerage, and prop firm accounts.

02

Automatic strategy re-enable

After a disconnect or restart, NinjaTrader leaves your strategy disabled — the chart looks live, but nothing is managing the position. Ninja Watchdog re-enables the exact strategies that were running, only after the account is reconnected and data is live.

03

Repair NinjaTrader

One-click repair for NinjaTrader not opening, slow performance, stuck processes, database errors, workspace problems, and strategy restore issues. It repairs common NinjaTrader issues and doesn't report done until the platform can reopen, reconnect accounts, and restore strategies.

04

Trade and order alerts

Receive email alerts when NinjaTrader strategies enter or exit trades, orders need attention, or recovery changes strategy status.

Alerts that read like a trading log

Every trade, order issue, and recovery lands in your inbox with the account, instrument, connection, and exact event time. Similar activity is grouped into one email, so a busy session or one connection problem doesn't bury you in duplicates.

From the founder

Why Ninja Watchdog exists

I've traded with NinjaTrader nearly every day for over 15 years, and I build and run my own automated strategies on it — live, self-funded, and across prop accounts. The tech was always the weak link: random disconnects, internet drops, a VPS that rebooted overnight while my accounts had open positions.

One night I went to sleep with NinjaTrader copy-trading 20 Apex PA accounts. Overnight it disconnected. The trades that should have closed never did. By morning, every one of those accounts was blown. Anyone who has run 20 PA accounts knows that feeling — $3,000 in fees gone to a tech failure, not a trading decision.

That was the last straw. I built Ninja Watchdog for myself first, and refined it for months until I could walk away for weeks and trust that my strategies were still running. Then friends hit the same problems and asked for it. Then word spread, and a private tool had to become a real product — rebuilt from scratch with cloud monitoring, alerting, and recovery that scales. That's what's watching your setup today: the same tool that watches mine, every night.

Pricing

NinjaTrader won't re-enable your strategy. Ninja Watchdog will.

After a disconnect or reboot, NinjaTrader comes back with your strategy disabled — the chart looks live, but nothing is managing the position. Ninja Watchdog reopens the platform, reconnects Rithmic or Tradovate, re-enables the strategies that were running, and emails you a recovery report.

One ES point is $50 per contract. A strategy that dies on an overnight reboot and leaves a position unmanaged through a 20-point move is a $1,000 mistake — per contract. Ninja Watchdog is $99/mo and watches every minute you don't.

FAQ

Questions before you start

Fast answers for traders protecting automated NinjaTrader strategies on a local computer, laptop, or VPS.

What is Ninja Watchdog?

Ninja Watchdog is a Windows app plus 24/7 cloud monitoring that automatically recovers NinjaTrader 8 after crashes, VPS reboots, and Rithmic or Tradovate disconnects. It relaunches NinjaTrader, signs back in, reconnects accounts, re-enables the exact strategies that were running, and emails a recovery report — and it never places, modifies, or cancels orders. It costs $99/mo after a 30-day free trial.

How do I automatically recover NinjaTrader after a crash or computer reboot?

Ninja Watchdog relaunches NinjaTrader, signs in, reconnects the accounts that were previously connected, and re-enables the strategies that were running before the interruption.

What happens to my open positions and working orders during recovery?

Your working orders rest at your broker while NinjaTrader is down — Ninja Watchdog never cancels or modifies them. When your strategy is re-enabled, it picks up the position and orders it was managing and continues where it left off.

What happens if a NinjaTrader strategy is disabled after a disconnect, crash, or reboot?

Ninja Watchdog detects when strategies that were previously running are no longer enabled, then re-enables them after NinjaTrader is open, connected, and ready. That is how automated trading setups recover from crashes, VPS reboots, power outages, and broker connection interruptions.

Can Ninja Watchdog reconnect NinjaTrader after Rithmic, Tradovate, or connection lost errors?

Yes. Ninja Watchdog monitors NinjaTrader connection status, detects broker or data-feed disconnects, and automatically reconnects affected accounts. Once the connection is stable again, it continues recovery by restoring the strategies that were interrupted by the disconnect.

Why not just use the built-in NinjaTrader reconnect settings?

Built-in reconnect settings ride out brief data blips, but they will not relaunch NinjaTrader after a crash or VPS reboot, will not sign back in, and will not re-enable a strategy the interruption disabled. Ninja Watchdog covers the whole chain — process, login, connection, and strategy state — and emails you what it found and what it fixed.

What if my VPS or computer goes completely offline?

Ninja Watchdog includes 24/7 cloud monitoring. If your machine stops reporting — a VPS outage, a network failure, a hard crash — our servers detect the silence and email you, even though the machine itself cannot send anything.

How does the 30-day free trial work?

Create your account and enter a payment method at Stripe checkout — $0 is charged today. Every Ninja Watchdog feature is included for 30 days, and we email you a reminder 7 days before the trial ends. Cancel anytime before then from your account and you pay nothing; if you keep it, billing starts at $99/mo after day 30.

Can Ninja Watchdog fix NinjaTrader launch failures, lag, or database problems?

Yes. One-click NinjaTrader repair clears stuck processes and fixes common launch failures, database errors, slowdowns, workspace problems, and strategy restore issues, then verifies the platform can reopen, reconnect accounts, and restore strategies.

How do I receive NinjaTrader trade and order alerts by email?

Enable trade and order alerts in Ninja Watchdog to receive email alerts when automated NinjaTrader strategies enter or exit positions, when orders run into issues, and when recovery needs attention. Alerts are email today; SMS and mobile push are on the roadmap.

Does Ninja Watchdog work on my desktop, laptop, or Windows VPS?

Yes. Ninja Watchdog runs on Windows computers that run NinjaTrader — desktops, laptops, dedicated servers, and any Windows VPS provider. It is not locked to one VPS provider.

Who needs NinjaTrader automated strategy protection?

If your strategy, copy-trading setup, or vendor automation depends on NinjaTrader staying open, connected, and enabled while nobody is watching, Ninja Watchdog is built for that setup — especially unattended overnight sessions on a VPS.
