had the same thing with fxcm, some people had money taken out of their accounts because of this, some people didnt..

WHY: because if say your at 1.2334 and a huge amount of volume comes in its not always gonna go 5,6,7,8,9 and so on the next price might be alot farther away then the next such as 1.2335...basicaly they are losing money by giving you a price that was never hit that it actually jumped past it, so much money at the close of the bar that it skips all those inbetween and opens where it should...it sucks cause you could have a stop and it misses it by 10 or so points then it takes out there, but hopefully this wont happen alot...i havent seen it yet i dont use 1min charts but it used to happen even on 1hr charts with fxcm/refco,, wouldnt let you trade or do anything cause it was finding its price due to too much volume and time to calculate price
