Subject: File No.99-57, Proposed Rule Change and Amendment No.1 by th Author: Mike Ianni Date: 03/28/2000 1:11 PM This new rule is an absolute joke! The CBOE has set up rules (and you allowed them too!!!) so any order that allows them to buy below or sell above the NBBO and their auto execution stays on but if they are the best market then the order is held up and handled manually. WHAT A JOKE!! This is criminal! I can't believe that you allow them to turn off their auto execution. The auto execution should stay on 100% of the time!
