Because my daytrading strategy reverses, the ability to do it with the greatest speed and efficiency is valuable to me. Cybertrader allows short-to-long flipping in one buy, but not long-to-short. Tradestaton allows neither. The reasons for not allowing such are relatively garbage, as the code for each is fairly simple. Any flippers out there willing to share the names of firms that allow either or both methods of reversal? Thanks!
