Starting from May 1, the CME exchange сhanged the rules for determining a professional market participant, and as a result, increased the fee for the market data. In order to correctly define the professional participant, Ritmic has changed the connection parameters in their platform, as well as in API for platforms such as Quantower.

Problems during the connection to Rithmic

Market Data Connection Closed (Broken)

Sometimes, when connecting to the Rithmic, you may see the error "Market Data Connection Closed (Broken)". Below we will describe possible reasons and solutions.
This error message is most commonly encountered by new Rithmic users for various reasons and is not within the control of the Quantower platform.
Rithmic error "Market Data Connection Closed" in Quantower
Rithmic error "Market Data Connection Broken" in Quantower

Connection to Rithmic can be done in two ways:

  • directly, without using RTrader Pro platform. This approach allows only one platform to be connected.
  • through their RTrader Pro platform. This connection uses Plugin Mode and allows you to connect multiple platforms at the same time (!)
Use Rithmic plugin mode for multiple access
More often such error occurs for the following reasons:
  • You didn't accept agreements "Market Data Subscription Agreement" and "Market Data Self-Certification" during the registration on Rithmic's website or in R Trader platform. We recommend connecting through R Trader or R Trader Pro platforms to check your account.
    Solution: accept agreements in RTrader Pro platform
  • A new account was created less than an hour ago. Usually, the full activation of a new account takes from 30 minutes to 1 hour.
    Solution: open RTrader Pro platform and connect with your login. If the connection is successful, then your account is active in Rithmic system
  • Make sure that your login matches the Demo or Real connection
    Solution: try both connection options in Quantower
  • If Quantower was connected to Rithmic before via the RTrader Plugin (i.e. the checkbox Use RTrader is active), and at the moment the RTrader Pro platform is not connected or the Allow Plugins option is not active there, then Quantower will not be able to connect.
    Solution (several different options, not step-by-step):
    1) start RTrader Pro platform with Allow Plugins mode and connect again to your account in Quantower
    2) try to connect to Rithmic as a direct connection: close RTrader Pro platform, disable Use Rtrader option in Quantower settings and restart Quantower. After start Quantower again and connect to your account as a direct connection
Plugin Mode in RTrader Pro is disabled but active in Quantower
  • In the case of a direct connection (without RTrader Plugin mode), you cannot use the same login on different platforms at the same time. The connection can be only one login on one platform (!).
    When trying to connect with one login on different platforms, it can log out from the first platform (which was connected), but the login on the second platform will not be successfully connected (on which we are trying to log in).
    Solution: use RTrader Plugin mode for multiple connections or close all platforms and connect via Quantower as direct connection (without Rtrader plugin mode)
  • The error can be encountered because the Rithmic server is unavailable to be connected to. This error commonly can be encountered over the weekend. In this case, it is best to wait until Sunday evening to see if you can connect to determine if this is the problem or there is some other problem.
  • Rithmic demo accounts are limited to 14 days per exchange guidelines on providing live, streaming data. If you have used a Rithmic demo previously you will not be able to login with a new Rithmic demo Username.
  • If you are unable to connect within a few days, you need to contact your broker about this issue.
If you enable Use RTrader plugin in Connection Settings and still can not connect to Rithmic, please check that you have more than 1 active session for Market data.

No Level2 data for some symbols

This problem can be due to the fact that you do not have a subscription to this Level2 data. To check this, launch the RTrader Pro platform and open the Order Book panel.
If you don't have Bid/Ask values in the RTrader platform, you need to subscribe to this data via Rithmic's support. After that, you will see level2 data in our platform as well.
