Hi guys:
I use a proprietary platform called tradepipe. It has multiple execution screens that really helps me out as well as proprietary tool that help me auto scale in positions. Some of the larger CTA's out there utilizes this platform.
My broker is Raymond Tong at rtong@pricegroup.com. He isan honest guy and quite competitive with rates.
Anyways, my 2 cents......hold it can help any.
