At the opening bell....HDSN was one .0001 on the ask. At about 11:32 HDSN jumped back to .0002 on the ask with all of the other MMs (short of the one that sits at .0003). I don't THINK we had a bid all day along. There was a period of about 2 1/2 hours near the close bell where I didn't have my eyes on the L2 screen.
