Can You Use Two Rithmic Connections on NinjaTrader?

The short answer is that NinjaTrader can work with multiple connections, but the real prop firm problem is more specific: traders want multiple supported Rithmic prop firm accounts connected inside the same NinjaTrader instance at the same time.

That is different from simply asking whether NinjaTrader has a multiple connections menu. The problem shows up when a trader wants the accounts connected together so a local copier can copy trades across supported accounts without relying on a cloud copier route.

Why this question comes up#

Prop firm traders usually start with one account and one connection. The setup is simple: connect NinjaTrader, connect the data feed, open the copier, and trade.

The problem changes when the trader adds more accounts. A trader might have supported accounts from multiple Rithmic prop firm environments, multiple evaluation accounts, or a mix of supported prop firm and live account setups. At that point the question becomes:

Can I get all of these Rithmic accounts connected in NinjaTrader at the same time?

For local copy trading, that question matters more than the copier brand. If the accounts are not connected inside NinjaTrader first, the copier cannot manage them inside the same workspace.

Two Rithmic connections is a connection-layer problem#

Many traders search for another copier when they run into this issue, but the copier is usually not the first problem. The first problem is the connection layer.

PropFirmConnector is built around that exact connection-layer issue. It helps supported prop firm traders connect multiple Rithmic connections in one NinjaTrader instance, then use the local NinjaTrader copier they already trust.

That means the workflow is:

1. Connect the supported Rithmic accounts in NinjaTrader.
2. Keep the accounts available inside the same NinjaTrader instance.
3. Let Replikanto, Apex Copier, Affordable Indicators Copier, or another local NinjaTrader copier handle the actual copy trading.

Why same-instance copy trading matters#

Same-instance copy trading keeps the setup simpler because the copier works inside the same NinjaTrader environment where the accounts are connected. That avoids depending on a third-party cloud signal route just to get orders between accounts.

For traders managing multiple supported Rithmic prop firm accounts, that matters because the goal is not just to place trades. The goal is to keep the account setup stable, visible, and available in the trading workspace where decisions are actually made.

What to check before adding the second connection#

Before trying to run two supported Rithmic connections, confirm the basics first.

Start with account type. Make sure both accounts are actually supported Rithmic accounts and not one Rithmic account mixed with another platform path. Prop firm account setups can look similar from the trader side, but the connection method matters.

Next, confirm account status. A reset, payout transition, or newly issued account can change the credentials or account assignment. If the account is not active or assigned correctly, NinjaTrader cannot make it useful for copy trading.

Then confirm the copier workflow. If the end goal is local copy trading, decide which account is the leader and which accounts are followers after the accounts are visible in NinjaTrader. That order keeps you from troubleshooting copier settings before the connection layer is ready.

Finally, avoid building around temporary workarounds. Two connections is often the beginning of a larger account setup. A trader who needs two supported Rithmic accounts today may need five later, so the setup should be able to scale beyond the immediate account count.

When two Rithmic connections becomes more than two#

The same issue often grows past two accounts. A trader might start by asking whether NinjaTrader can use two Rithmic connections, then quickly need three, five, or more supported account connections.

That is why the real goal is not only “two Rithmic connections.” The stronger setup is multiple Rithmic connections in NinjaTrader.

Bottom line#

Yes, the setup people are searching for is possible when the account connection problem is solved first. PropFirmConnector is designed for traders who need multiple supported Rithmic prop firm accounts connected inside one NinjaTrader instance before their local copier does the copy trading.
