If you are the seller of an auction and you are logged in, the web site will display a 'Sales Pending' text on the upper right side of the web page when viewing the item. The number next to the Sales Pending is the number of items in your lot that have been committed to be sold.
For a single item auction, if any bidder has met your reserve price this number will show a one. If you have no reserve price, then any bid will result in a possible winning bidder.
