I have never fully understood market makers. Do they work for the company (in this case ISF)?
It's interesting that you weren't able to place your order above $0.08 but it opened @ $0.160.
As for possible counter bidder, I have no idea. There's been a few speculations floating around already.
Personally I'd prefer a big U.S. health IT player (like Ingenix which has been named in the initial rumour) compare to say CompuGroup or Cohen. I think another U.S. player picking up ISF would pose greater threat for CSC because they'll able to compete in Aust, UK/Europe, and the U.S. as well. Whereas a German Co. might be disadvantaged in U.S. soil.
