They took my top profit!

As I am new to forex I will not give a overall review only what I have noticed. There is a delay in entering a trade and exiting, this delay appears to allow them to manipulate the pips. On average they pick up 1 pip on entering and 2 on exiting . I joined due to there advertised low spreads, when the 3 pip loss is taken into account itis not such a good deal. I find there claims misleading. Not sure if you would call this a scam. I have not yet tried to withdraw funds so cannot comment.
