If I use widget plugs to try to sell traffic but fail to create any plugs (to receive traded hits) for my site then from what I understand some traffic is still traded and this shows up in the stats section while the traffic I sell shows up in earnings section, right?

So if I have a bunch of credits in stats that I haven't used if I were to create some plugs I would suddenly get a lot of traded hits back for all the traffic I sent in the past when I had no plugs (to receive). Is this correct? Or do you lose those credits after some time?
