Connecting a Rithmic Account to ATAS

This guide explains how to connect a Rithmic account to ATAS. There are two available connection methods:

Connecting a Rithmic account directly to ATAS
Connecting a Rithmic account through RTrader Pro
Important Rithmic connection characteristics

To create a Rithmic connection in ATAS, open:

Connections → Add → Rithmic → Next

An agreement confirmation window will appear.

OCO (One Cancels Other) orders are simulated locally on your computer. The platform must remain connected to your broker for OCO orders to function correctly. If the connection is lost and one order from an OCO group is executed, the remaining orders will not be canceled automatically. If you agree with these conditions, click I Accept, Please Continue.

Connecting a Rithmic Account Directly to ATAS

The account must not be connected to RTrader Pro or any other trading platform.

Enter your Rithmic account login and password.
Select the appropriate server provided by your broker.
Optionally enable Aggregated Quotes. This reduces CPU usage by receiving simplified market data, but it also reduces the update frequency of market information.
Make sure the Connect via RTrader Pro option is disabled.

Connecting a Rithmic Account Through RTrader Pro

Only one Rithmic account can be connected to ATAS through RTrader Pro.
The connection settings in ATAS and RTrader Pro must match.

Download and install RTrader Pro:

https://downloads.rithmic.com/rtraderpro.msi

After installation:

Log in to RTrader Pro and enable Allow Plugins.
In ATAS, enable Connect via RTrader Pro in the Rithmic connection settings.
If required, enable Aggregated Quotes. This option must be configured identically in both RTrader Pro and the ATAS Rithmic connector.

For this connection method, both ATAS and RTrader Pro must be running simultaneously.
The selected server must be the same in both applications.
If you are unsure which server to use, contact your broker.

After the connection is configured, it will appear in the connections list.

Detailed information about the connection settings window is available in the article: Connection Settings Window.

Important Rithmic Connection Characteristics

The Rithmic connection is sensitive to both network quality and CPU load. High processor utilization or network instability may cause connection interruptions.

Possible Connection Issues

If a Rithmic server becomes unavailable, connection attempts may take longer than usual. After switching servers, you may need to wait several minutes for the previous session to close.
ATAS may display a Connection Interrupted message.
Rithmic may report a possible connection issue using messages such as: "PnL Connection - Heartbeat has been quiet for XX seconds".

Possible Consequences

Price, volume, and position information may be displayed incorrectly if the PnL connection is affected.
Order status updates may not be received if the trading connection is affected.
ATAS displays a notification containing the message received from Rithmic.
When placing new orders after such warnings, ATAS will request confirmation and display the most recent Rithmic connection messages.
