How to delete a list
To delete a custom symbol list from the watchlist, open the dropdown box at the top of the section and click on “Open list…” (or use the Shift+W hotkey). In the dialog that appears, hover over the list title, then click on the remove button.

A flagged list will be automatically deleted once all its content is cleared (the red list is always available by default). This means that the list will be erased when all the symbols have been removed. To remove a symbol, you need to either un-flag it or click on the remove button.
