Could have been helpful for the article to include a tutorial:

In the filters, there’s one for “completed” and “sold,” you want both checked.

Why would you want "Completed" if you want to know how much an item sells for? This would be telling you how much it didn't sell for.

If both are checked it only displays “sold” items. For some reason the eBay UI used to auto-check “completed” whenever “sold” was selected.
