All the other trading software I've used provides a Message Monitor window that lets users know what's happening with each order and the system in general.
Due to that Amex halt today, I watched a stock move 40 cents against me while a market order was working for 15+ minutes. Support later figured out that I needed to have RTH only unchecked in order config to execute on ECN's. If they had a message monitor window spitting out the message "Order not sent because regular hours trading is halted" I would've been able to figure out that I needed to switch that setting.
