For Existing users who were already using MotiveWave with another broker here are the steps to add either "CQG" or "Rithmic" connections to MotiveWave.
Launch MotiveWave and you should already see your existing workspace visible from your other broker.
Select "Options" menu and then "Workspaces" and then select "New Workspace" button at the bottom of the "Manage workspaces" window. Simply Create a "Workspace name" of your choice and then select either "CQG" or "Rithmic" for your service provider. Enter your Username and select the proper server and hit "Create workspace".
Now you can select your new workspace profile name on launch of MotiveWave to connect.
