Just spent my first day with Level 2 quotes. The software I'm using does not show level 2 quotes as tenths of a cent. It only shows rounded cents. I sent a email to thier help desk, and maybe I'll get a reply ? Do some companies only offer rounded cent Level 2 quotes ? If so, who offers tenth of a cent breakdown in thier Level 2 quotes. It did help me squeeze a little more profit than I would have made without it.
