Nothing surprises me with FXCM.
Looking at the screenshots in the very first post, it explains why at news time or just before, you click on a price presuming that's the price that you click on but you wind up being filled at the hidden price with huge slippage.
The point is at the moment you click you cannot see that the price has moved some 20 pips or away in the background by everything you click on your screen. This looks to me.
