Switch Connections in a Workspace
Create a new workspace connected to your new connection.You may want to switch connections in a workspace (e.g. CQG to Rithmic or TDA to IB). Since the connections will use different symbology just removing the old connection and adding the new one will cause issues. This is the preferred method:
Backup your old workspace (File > Backup).
Create a new workspace connected to your new connection.
Open this brand new workspace and then restore your old backup (File > Restore).
Using the method above will prompt MotiveWave to attempt to map the symbols over from your old connection to your new connection. Some instrument may not map correctly, in this case they will need to be added manually.
