How to keep multiple prop firm accounts connected in NinjaTrader (2026)

The 3 a.m. problem multiplies with every funded account

Our whole product exists because NinjaTrader dies at 3 a.m. — a VPS reboot, a Windows update, a 90-second Rithmic drop — and your strategy comes back disabled with nobody managing the position. Run four funded accounts instead of one and the same outage multiplies: every minute of downtime is now exposure on four accounts at once.

This guide lays out the reliability stack we recommend for funded futures traders: Ninja Watchdog to keep NinjaTrader up, connected, and recovering on its own — and PropFirmConnector to get every prop firm account into that one NinjaTrader in the first place.

Can NinjaTrader keep multiple prop firm accounts connected at the same time?

No — a stock NinjaTrader 8 install maintains a single live Rithmic session, so connecting a second funded login means dropping the first, and some firms' Rithmic accounts don't appear in NinjaTrader's connection list at all. The PropFirmConnector add-on lifts both restrictions: separate Rithmic logins from DayTraders.com, Lucid, Apex, or several firms at once run side by side in one account list, one DOM, one workspace.

For a multi-account trader, that consolidation is what makes the operation manageable: one platform to watch, one local copier (Copilink and Replikanto are the usual picks) mapping the lead account to followers, one machine to keep alive.

Which prop firms need an add-on to connect to NinjaTrader?

Every Rithmic prop firm can reach NinjaTrader 8 one way or another, but the route differs: five popular firms connect natively for a single account, two big ones issue Rithmic account types that only the add-on can connect, and three have no native NinjaTrader route at all.

• Native, one account at a time — Apex Trader Funding, Take Profit Trader, Bulenox, Elite Trader Funding, and OneUp Trader connect natively, but running several logins simultaneously requires the PropFirmConnector add-on.
• Rithmic account types need the add-on — Lucid and Tradeify sell native-NinjaTrader accounts as a separate account type; their Rithmic accounts connect to NinjaTrader only through PropFirmConnector.
• No native route — DayTraders.com, PropShopTrader, and Humble Funding issue Rithmic credentials that stock NinjaTrader can't use without PropFirmConnector.

What actually breaks in an unattended multi-account setup?

Four things take down an unattended NinjaTrader: a scheduled Windows update, a VPS host reboot, a platform crash, and a Rithmic disconnect. In every case the result is the same — the platform is closed or disconnected, any strategy that was running comes back disabled when the platform restarts, and no one is watching the positions on any of the accounts.

The failure modes are mundane, which is exactly why they catch traders: a copier can't mirror orders from a platform that isn't running, so the same hiccup that used to threaten one funded account now leaves all of them unmanaged at once.

How do you make NinjaTrader recover on its own?

This is Ninja Watchdog's job, and it's deliberately boring: when NinjaTrader 8 crashes, the machine reboots, or a Rithmic or Tradovate connection drops, it relaunches the platform, signs back in, reconnects the accounts, re-enables the exact strategies that were running, and emails you a report of what happened. If the machine itself goes silent, the cloud side detects it and emails you that too. It never places, modifies, or cancels an order — recovery only.

Put the two together and the coverage is complete: every funded account lives in one NinjaTrader, and that one NinjaTrader is watched around the clock and comes back on its own. The trader finds out from the recovery email, not from a drawdown.
