Which prop firms use Rithmic?

NinjaTrader 8 supports Rithmic, but not uniformly. A named native connection exists only for some firms — 4PropTrader, Apex Trader Funding, Bulenox, Elite Trader Funding and a handful of others — and NinjaTrader runs one Rithmic connection at a time. Three situations therefore come up constantly for traders on the firms listed above:

• No native route at all. DayTraders.com, Humble Futures Funding, PropShopTrader currently issue Rithmic accounts while documenting NinjaTrader as unsupported. Their logins work in NinjaTrader only through an add-on connection path.
• Native on a different feed only. Earn2Trade, Lucid Trading, Phidias Propfirm, The Trading Pit, Tradeify offer NinjaTrader natively through another data feed, so the Rithmic version of their accounts still needs the add-on route.
• Native, but single-login. Firms with a named NinjaTrader option — like 4PropTrader, Apex Trader Funding, Bulenox — connect natively one login at a time. Running several evaluation or funded accounts side by side, or accounts from two different firms, exceeds what the native connection allows.

PropFirmConnector covers all three cases: it adds an independent connection path inside NinjaTrader 8 for any firm-issued Rithmic login and runs multiple Rithmic connections simultaneously in one instance — which is also what makes local trade copying across prop accounts possible. See the trade copier guide for that workflow.

The 2026 platform reshuffle — firms that changed feeds

Prop-firm data feeds moved a lot in 2026, which is why older firm lists are wrong. Topstep consolidated new accounts onto its own TopstepX platform after ProjectX became Topstep-exclusive in February 2026, so Topstep no longer appears in Rithmic’s directory for new accounts. Earn2Trade ended its bundled NinjaTrader-plus-Rithmic access on June 30, 2026 — its Rithmic accounts continue on other front ends, and NinjaTrader access there now runs through a different feed. Tradeify went the other direction, launching its Rithmic-based TradeSea stack in March 2026. The table above reflects Rithmic’s directory as of the verification date, and each connection guide records its own last-verified date.
