RJC...just FYI in case you didn't realize it...
The current downside to exiting during the day, then restarting, is that your Time of Sales history accumulated to that point in the day will disappear, and your TOS info will start again from scratch. As this is one of the problems that they are aware of, there’s always the possibility that this limitation will disappear in the next update.
This same thing has ALWAYS been the case with my Scottrade Elite L2 platform, so I'm not even sure that's something they will need or want to fix. It's standard for all similar platforms to the best of my knowledge.
