An important feature of Rithmic connection.

Often the Rithmic connection is quite sensitive to the communication channel and CPU load. If the CPU is heavily loaded or there are problems with the communication channel, the Rithmic connection may become unstable.

There may be the following connection problems:

1. If you enable the plugin connection and then try to connect without the plugin, it will not work until the application is restarted.

2. If you create 2 connections, one with the connection via plug-in, and the second - without, the second one will not connect.

3. If one of Rythmic servers is unavailable, the connection may be waiting for a long time. You connect, a minute passes, you get an error, then you change the server and connect again->you will ned to wait a several minutes until the previous connection closes completely.

4. Connection lost. In this case, ATAS will pop up the notification.

5. Potential connection loss. This is a kind of intermediate state between connected and broken connection. At such moments, Rithmic sends messages like: ‘PnL Connection - Heartbeat has been quiet for XX seconds’ . Instead of a PnL connection, there can be Trading Connection, History Connection, etc. These messages indicate that there was no data exchange with the corresponding Rithmic connection (PnL, trading, historical, etc.) for a certain number of seconds. For a trader, this can mean the following:

   1. If there are problems with the PnL connection: perhaps the price, volume, direction of positions (which were received before from a working connection) in ATAS may be different than others on the Rithmic servers.

   2. If there are problems with the trading connection: submitted orders may be sent to the Rhimtic servers, but their statr may not be recieved back to ATAS

6. That means, if there are problems of this type with Rithmic connections, ATAS cannot guarantee if the displayed information is correct. Therefore, ATAS provides 2 mechanisms to protect a trader from such situations:.

   1. When receiving messages likePnL Connection - Heartbeat has been quiet for XX seconds , ATAS displays a pop-up window in which it displays the text of this message.

   2. If user tries to place orders or change the position after recieving those messages, ATAS will require confirmation of the operation, which will indicate all messages from Rithmic that were received earlier:
      
      

In this case, the user will need to decide for himself whether to execute this order or not.
Similar messages are issued if the user trades through a Portfolio Group,
which includes the Rithmic account that received the message data.
