Investor Help (NO Ihub questions)

[tripNpennies]

I have a question... I am not getting any answers on my other boards so I thought I would ask people here since this board is very active... I was looking at the ONSM quote and specifically the trades section (http://ih.advfn.com/p.php?pid=trades&symbol=ONSM) yesterday there were 47,500 shares sold at .001 after the close of the market and today it looks like there is almost 20,000 sold @ .001... Can anyone explain this to me? Where are these shares coming from and how come they aren't included in the volume for the day and basically can't be found anywhere else?? I would much appreciate an answer because this is boggling my mind when I should be studying!!!!
