Wow, did you try switching servers a few times. I was trading both equities and futures all day on Tradestation and wasn't disconnected once.
My TS7.2 was working great today. No problems. I had a day like you describe a couple of weeks or a month or so ago. I had gotten the cache corrupted. I deleted it and it worked great. Delete your cache next time u have problems. It may solve it. John
Lot's of bad luck this week, ts goes down at a very bad time. I executed a long an unwanted buy of SPY earlier today , rare wild click of the mouse, (got out with minimum pain) , general malaise.
