Using Two Different Rithmic Connections in NinjaTrader (2025)

Managing multiple Rithmic connections in NinjaTrader can be tricky since only one connection can be active at a time. However, by configuring Multi-Provider Mode and using separate credentials for each account, you can efficiently switch between trading setups. Here’s what you need to know:

• Setup Basics: Install the latest NinjaTrader version and enable Multi-Provider Mode.
• Credentials: Each Rithmic connection needs unique login details (Primary for live trading, Secondary for evaluation accounts).
• Switching Accounts: Disconnect from one account before connecting to another; wait 30–60 seconds to avoid issues.
• Licenses: A Multi-Broker license may be required for multiple data feeds.
• Data Limits: Weekly tick data is capped at 40GB; manage usage carefully.

NinjaTrader How to enable Multi Provider mode for Rithmic …

System Requirements

Make sure your system meets the necessary technical specifications and that you have the required licenses and credentials.

Setting Up Multi-Provider Mode

Multi-Provider Mode allows you to manage Rithmic connections. While the platform lets you switch between connections, only one can be active at a time. To enable this feature:

• Platform Version: Install the latest version of NinjaTrader (2025).
• Connection Type: Select "Rithmic for NinjaTrader Brokerage" as the connection type.

Required Rithmic Credentials

Each Rithmic connection requires its own set of credentials:

The "Evaluation (Rithmic)" entitlement is essential for accessing Rithmic-based evaluation accounts in NinjaTrader ^[2].

Multi-Broker License Check

For Standard Users, a "Multi-Broker" license (Single Instance Multiple Connection) is required to connect to multiple data feeds ^[1].

Evaluation/Prop Firm Users typically don’t need a Multi-Broker license, as these accounts already include the "Evaluation (Rithmic)" entitlement ^[2].

Legacy Users with a Lifetime License Key purchased before March 2023 automatically received the Multi-Broker add-on without additional cost ^[2].

Keep in mind, this connection type only allows one active connection at a time, requiring manual switching between accounts ^[2].

Refer to the Connection Setup Guide for step-by-step configuration instructions.

Connection Setup Guide

Here’s how to set up and manage multiple Rithmic connections in NinjaTrader.

First Connection Setup

Start by creating your primary connection through the Account Connections menu:

• Launch Connection Manager: Go to Tools > Account Connections.
• Add Connection: Click "Add" and pick "Rithmic" from the list.
• Enter Details:
  • Connection Name: Use a clear name like "Rithmic-Primary."
  • Environment: Choose "Live" or "Demo."
  • Username: Enter your main Rithmic username.
  • Password: Type in your password.
  • API Key: Add your Rithmic API key.

Click "Connect" to test the setup. A green indicator means you’re good to go.

Second Connection Setup

To set up a secondary connection:

• Go to Tools > Account Connections.
• Create a New Profile: Click "New" to set up a separate connection.
• Enter Secondary Details:
  • Connection Name: Use a unique name like "Rithmic-Secondary."
  • Environment: Select the correct one for your needs.
  • Credentials: Input your secondary account details.
  • Entitlement Verification: Ensure the "Evaluation (Rithmic)" status is active.

Once both connections are configured, you can easily manage them within NinjaTrader.

Connection Management

1. Switching Between Connections

When switching, wait 30–60 seconds to avoid data feed conflicts.

2. Monitoring Connection Status

Check the connection status in the status bar. Active connections show in green, while inactive ones appear gray.

3. Verifying Data Feeds

After switching:

• Ensure charts are updating with current prices.
• Confirm that order routing is functioning as expected.

This setup ensures smooth operation for multiple Rithmic accounts in NinjaTrader.

Common Applications

Data Feed Management

Use multiple Rithmic connections in NinjaTrader to fine-tune your data feeds. Assign the primary connection for real-time data and execution to minimize latency.

Rithmic’s software is built for low-latency, high-throughput performance ^[4].

The secondary connection can handle tasks like:

• Historical data analysis
• Market research
• Strategy backtesting
• Paper trading

This setup avoids resource conflicts and ensures smooth performance. To manage multiple data streams, enable Multi-Provider Mode during configuration ^[3].

These strategies help maintain efficient operations, which ties into account management discussed below.

Account Switching

Simplify account management by assigning each connection to a specific account type:

• Evaluation Accounts: Use unique Rithmic credentials for programs like Topstep‘s Trading Combine. This keeps evaluation activities separate from other accounts ^[3].
• Live Trading: Ensure you have the proper Multi-Broker License, Rithmic entitlements, and R|Trader Pro setup ^[3].

Keep in mind: Only one connection can be active at a time ^[2].

System Limitations

It’s important to understand these restrictions for effective connection and platform management.

Single Active Connection Limit

NinjaTrader supports only one active Rithmic connection at a time. If you need to switch connections, you must disconnect completely before setting up a new one. Using the same login credentials across multiple platforms can lead to disconnections. Note that older configurations allowing multiple connections are no longer supported ^[2].

Switching Time Requirements

Switching between Rithmic connections involves a specific process ^[2]:

1. Disconnect from the current connection, ensuring all trades and positions are closed.
2. Wait for confirmation that the disconnection is complete.
3. Initiate the new Rithmic connection.
4. Confirm the new connection is active before proceeding with trades.

Following these steps ensures a smooth transition and minimizes disruptions.

Technical Restrictions

There are also technical limits that impact how the platform operates. One key restriction is the weekly tick data download limit, which can pause access to historical data once exceeded.

To avoid hitting these limits:

• Reduce the use of volume analysis tools to conserve data ^[5].
• Limit chart data to six months when performing volume analysis ^[5].
• Use the "Reload data (server)" option only when necessary ^[5].

These restrictions are especially relevant for traders relying on tools like volume profiles or cluster analysis. While real-time data remains unaffected, staying mindful of historical data usage helps prevent interruptions.

Troubleshooting Data Feed Issues

If your connection is working but data feed problems continue, try these steps:

• Check your Level 2 data subscription: Open the Order Book. If bid/ask values are missing, contact your broker for assistance.

• Reload historical data: Use NinjaTrader’s data management tools to refresh data if inconsistencies appear.

Verifying Account Setup

Once connection and data feed issues are resolved, confirm your account settings:
