MBtrading demo account. I checked the system at approx 2am eastern time and it was running fine. When I checked again at 4 am, it had logged off. When I logged back on, I had an open order (GBP/JPY) without any record of the order or fill in the book, just an open position. Any trades from the previous 12 hours were not in the order book either. Also, their charts appear to update randomly, at this posting 4:40 EST, 1 chart has not updated since 4:40. Anyone have experience with this fx broker?
