If your T3 connection is not working
- Should Plug-in mode be on or off?
- Off. Plug-in mode shares a running R|Trader Pro session with NinjaTrader, which is a different setup from PropFirmConnector’s direct connection. In Connections > Configure, select your Rithmic connection, uncheck Plug-in mode, click OK and connect again. Some firm and Rithmic instructions turn it on for their R|Trader Pro workflow; leave it off for PropFirmConnector.
- The connection is green, but the account isn’t in NinjaTrader’s Accounts tab.
- Your NinjaTrader login is probably missing the general Rithmic entitlement, so the Accounts tab often shows only Sim101. In NinjaTrader, open Help > About. The Entitlements line should say Evaluation (Rithmic); if it doesn’t, the connection can turn green without showing your accounts. Older NinjaTrader accounts don’t have this entitlement by default, but newly registered accounts do. The fix is in your NinjaTrader account, not in Rithmic or your firm’s dashboard, and you only do it once.
Correct: Entitlements lists Evaluation (Rithmic). Machine ID and User are hidden. If Evaluation (Rithmic) is missing:
- Import this license key at account.ninjatrader.com: click your initials, then Settings > Plans > Import license key. Paste the key, click Import, then close and restart NinjaTrader.
@APE-XTRA-DERF-UNDI-183T-PR45-LW27-63GE - No Import license key button, or still missing? Trading mainly with prop firms? Your NinjaTrader login doesn’t matter, so the fastest fix is to create a new NinjaTrader account with a different email and sign in with it.
- Keeping your current login, for example because it has a live account on it? Email platformsupport@ninjatrader.com with your NinjaTrader username and ask them to enable the general Rithmic entitlement.

- Import this license key at account.ninjatrader.com: click your initials, then Settings > Plans > Import license key. Paste the key, click Import, then close and restart NinjaTrader.
- The T3 Rithmic login is rejected.
- Test the same credentials in R|Trader Pro, accept any pending market-data agreements, and select Rithmic Paper Trading (Chicago) in NinjaTrader.
