Deposit home exchange of securities in multi-channel ordering
You can use a user-defined field to define a home exchange for securities that you wish to trade via multi-channel ordering.
In the "PSI Order Entry - Configuration" dialog box, enter the name of the user-defined field created for this in the "User-defined field" input field on the "General settings", "Multi-channel ordering settings" tab.

The home exchange entered in this user-defined field for a security is to be seen as a "master date" rather than an available trading venue for the actual ordering.
