Why It Matters

Why Leeloo Traders Search for This

Most traders reach this page for one reason: Leeloo Trading hands you a Rithmic login (a User ID that starts with LL, like LL001755, arriving in the 'Welcome to Leeloo' email) and full NinjaTrader 8 support with a free SIM license key, but the moment they try to log a second Leeloo account into NinjaTrader, it stops. NinjaTrader's native Rithmic adapter only permits one active Rithmic connection at a time, which blocks running several Leeloo accounts side by side in a single instance.

The fix is connectivity, not a different broker. Keep R|Trader Pro open and enable Plug-in mode, and multiple plug-in-capable platforms on the same machine can share the connection so your Leeloo accounts appear together in one NinjaTrader workspace. PropFirmConnector targets exactly this layer: getting the supported Leeloo Rithmic accounts connected first, so a local copier has a single account list to mirror across instead of fighting the one-connection limit.

Leeloo also actively permits copy trading. It sells its own 'Duplicate Account Actions' product and traders run local copiers like Replikanto across funded accounts. Note the practical ceiling: the simultaneous copy-trade cap has been reported reduced from 5 to 3 accounts, which directly shapes how many Leeloo accounts you map in one setup. Local copying inside NinjaTrader keeps that mirroring near-instant, with no cloud round trip.

Connectivity at a glance

Leeloo data feed & NinjaTrader setup

Data feed / login format
Leeloo accounts run on the Rithmic data feed. Credentials are Rithmic User IDs beginning with 'LL' (e.g. LL001755), delivered in the 'Welcome to Leeloo' email and used to log into both R|Trader Pro and NinjaTrader.
NinjaTrader 8 support
Leeloo officially supports NinjaTrader 8 (and 7) and provides a free NinjaTrader SIM license key with all accounts. You connect via the Rithmic adapter using the Leeloo-supplied username and password.
Multiple accounts in one NinjaTrader
NinjaTrader's native Rithmic adapter allows only one active Rithmic connection at a time. To run multiple Leeloo accounts at once, keep R|Trader Pro open and enable Plug-in mode so NinjaTrader connects through it.
Trade copiers permitted
Leeloo permits copy trading and markets a NinjaTrader trade-copier product ('Duplicate Account Actions'). Traders also use local copiers like Replikanto to sync orders and positions across accounts.
Copy-trade account cap
Leeloo limits simultaneous copy-traded accounts; the cap has been reported reduced from 5 to 3, which constrains how many accounts you can mirror in one copier setup.

Common Questions

Leeloo Rithmic and NinjaTrader FAQ

Q How do I connect my Leeloo Trading account to NinjaTrader 8?

Use the Rithmic adapter in NinjaTrader 8 with the credentials from your 'Welcome to Leeloo' email. Your username is a Rithmic User ID that starts with LL (for example LL001755). Leeloo includes a free NinjaTrader SIM license key, so you can connect and trade without buying a separate NinjaTrader license.

Q Why can't NinjaTrader connect to two Leeloo Rithmic accounts at the same time?

NinjaTrader's native Rithmic adapter only allows one active Rithmic connection at a time, so a second Leeloo login is blocked while the first is connected. To run multiple Leeloo (or mixed Rithmic) accounts together, you keep R|Trader Pro open with Plug-in mode enabled, or split accounts across separate instances and bridge them with a local copier.

Q How do I use R|Trader Pro Plug-in mode for multiple Leeloo accounts?

Open R|Trader Pro, sign in with your LL Rithmic credentials, and enable Plug-in mode, then leave it running. With Plug-in mode active, plug-in-capable platforms on the same machine, including NinjaTrader, can connect through that single R|Trader Pro session, letting several Leeloo accounts appear in one NinjaTrader workspace at once.

Q Can I copy trade across multiple Leeloo accounts with a local copier like Replikanto?

Yes. Leeloo permits copy trading and even sells its own 'Duplicate Account Actions' copier, and traders run local NinjaTrader copiers such as Replikanto. Once the accounts are connected in one NinjaTrader instance, the copier mirrors orders locally with no cloud round trip. Be aware Leeloo's simultaneous copy-trade cap has been reported at 3 accounts (down from 5).

Q Does Leeloo give a free NinjaTrader license, and is it SIM or live?

Leeloo provides a free NinjaTrader SIM license key with all accounts, so you do not need to purchase NinjaTrader to trade your evaluation or funded account. The license is SIM-tier, matching Leeloo's SIM-funded model where you trade in a simulated environment and earn real payouts under the firm's rules.

Q Is PropFirmConnector affiliated with Leeloo Trading?

No. PropFirmConnector is an independent connection-layer tool and is not affiliated with or endorsed by Leeloo Trading. It helps you connect supported Leeloo Rithmic accounts inside NinjaTrader for local copy trading; all Leeloo evaluation rules, drawdown limits, consistency requirements, and account caps are set by Leeloo.
