Do you mean ...Its a very quick jump of Ask price up from 3 to 30 pips... spread widening?
It could happen but if your stops are hidden how can broker stops hunt them.
Guys do you have any evidence or something?
yes spread widening. considering a 3 pips spread for the last 6 hours and you see a selloff coming in the next few minutes, if your stoploss is hidden the broker still knows its there with hundreds of other people's at the logical place you put stoploss such as before the last fractal or something, the broker still knows its there. if you see a 3 pip spread and put Stoploss at 30 pips to be safe, and the Ask jumps up to hit your 30 pip Stoploss....
or could FXCM broker be popping up the Ask price on individual platforms? Such as Bid stays same for everyone but each individual's Ask price jumps up just to their own stoploss on their own personal MT4 platform on their machine? I know MT4 Server has some sneaky tricks but that would be excessively fraudulent and someone should go to jail for that. thats pretty unlikely though.
You could try to put your stop somewhere else apart from the obvious place , you could trade after the spike has occurred , lets say your looking at eur/usd the obvious place was 06000 to take a trade so lets say most went short from this level , say we had a stoploss of 20-50 points the most obvious push would be at least 100 points to take out stops, but looking back on the 1hr chart you can see the final spike almost lines up with the support on the 23rd major sell bar, it takes it out by a few points, that's a signal but not always , that's when I would go short. That's an example, I'm sure you can see eur/usd is in an up trend even though eur sentiment is negative.
