I have definitely seen aberrations on their charts sometimes, and often wondered if these trigger stops - but this probably isn't what you're talking about anyway (as that would be highly illegal, for a glitch to take out the stop, as opposed to actual market movement).

What exactly do you think is happening? They actually buy and sell in the market themselves to get at your stops? Surely this wouldn't be viable for them unless you had a serious amount of money on the table?

Anyway I've used igmarkets. Sometimes the limits didn't trigger (one time had to place trade at higher level than limit), so had pretty much the opposite problem.

The only thing I didn't like was how they charge interest on CFDs, but don't offset any of this with funds sitting around in your account (that aren't committed to margin).

.. and ryan you should probably elaborate on that, what your experience was
