Can any customer tell me if the Tradestation system is a true direct access system or are they selling their order flow? How many different ECNS or exchanges should one commonly be able to route STOCK orders with a direct access system? Will they allow you to trade stocks beginning at 7AM EST U.S.? I directed these questions to the company itself 1.5 weeks ago on their e-mail form but never received a response. Thanks for any help.
