As I mentioned, Rushtrade has various pricing plans as well & they can handle it. http://www.rushtrade.com/fees.jsp
I would prefer to concentrate on our MBTX technology for getting better and faster fills. Thats is the foundation of MB Trading. I will however bring this up to see if I can accommodate. Steve
