Yesterday it was a special condition. The trades you are talking about were losers because it was trading during news. At that precise time it was a speach of BOE Chairman. The spike you are reffering to was due to this event and on my broker ibFX I has spreads in excess of 19 pips. I closed my trades manually and the loss on the last trade was only 14 pips because of that but was hedged by the previous trades who were winners. I was very close to lose only 1 pip but at that exact moment my broker gave me "off quotes" and then the spike started.
