Short answer

You can use the Notes feature on Arrow to add specific reasons for tracking instruments in your marketwatch. This helps you remember why you added particular instruments when you review them later.

Things to keep in mind

You can save notes by pressing Ctrl + Enter and close them by clicking on ✖ or pressing Esc (escape key). Your changes will not save if you close notes without saving them.
