Ebay Ratio 10/31/24 This is a very quick and general way to see ebay activity. Its not perfect nor predicts anything. Take the total search results in the thousands after filtering for "trading card singles" and remove the three zeros. Example. Michael jordan cards for sale has search results around 110,000. His number would be 110. Then with the same filter but add completed items and sold items. Do the same for that total. Example michael jordan sold items shows around 70,000 results. This number would be 70. So he would end up with 110/40. This means that there are more than double the number of items for sale then what has been sold.
