The CTS connection is considered a legacy connection and is not one for which we keep up any changes. That means that it could or could not work at any given time.

But, in your case, you have the following in your log:
CTS FIX: Received a Logout message. Text = User does not have permission to access this application | 2021-11-11 10:49:48.801
CTS T4 FIX | Contact your clearing firm and have them add the Sierra Chart application to your CTS T4 username. | 2021-11-11 10:49:48.801 *

Which is telling you that you need to get Sierra Chart added as an option to your CTS account. If TopStep can not do this for you, then you will need to use the Rithmic connection instead.

If you do need the Rithmic connection, then you will follow the instructions at the following link:

For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
