For those that use MT4 through Forex Ltd - go to GBP/USD and on a 1 hour or less timeframe and you’ll see a huge gap of data from Jan 2012 to July 2012. If you change your settings and go to history centre and refresh etc, you’ll end up losing more data. I’ve contacted the help desk and they are investigating but thought I would alert you (it’s consistent on 4 workstations, and 2 other people are experiencing the same issue).
