Hi,
The list of symbols is provided so you can specify the settings (eg. spread) of each symbol prior to export. This is of particular use when you have selected multiple symbols for export in the main screen. If you have selected say AUDCAD & EURUSD for export, you can select each from the drop-down and tailor their specific information. You can subsequently save the settings as default if you like so the next time you export it will use the same settings.
Hope this helps.
