I've had the same problem several times.. it's been a few weeks now and it isn't fixed.. i'm concerned and threatening to leave them. I was refunded the difference for my first trade where I discovered the problem... just so you know. They are having a serious software issue and if they don't get it fixed soon i'll be switching to tradestation. I noticed that I couldn't modify my stoplosses. This was in my opinion what made them better than Scott trade or any other cheaper broker... including Zeeco. The fact that as soon as I was filled my stop out and target limit were automatically submitted.... I noticed i couldn't move my autostop on some tickers.... making it difficult to manage with the use of a limit only in this volotile market.
