UI - Trading Terminal: Band under tabs → button to scroll left and right missing

When used on a monitor in portrait mode, the "band" under the tabs is not fully displayed in the Trading Terminal. There is no other way to do this. However, there is no button to move the band to the right and show the options that are not visible.

The band can currently only be moved to the right by selecting the text in the band and dragging the cursor to the right.

Please add two buttons so that you can scroll left and right in portrait mode.
