I have experienced much greater success since I started investing with TRUEFX because their account broker was very knowledgeable and helpful. Also you have an option that your broker will be the one to do the trades for you because that's their expertise and at the end of the day they will inform you about the status of your investment.
I've been looking for a simple trading website for a while now, without all the fancy mumbo jumbo that all these websites put. This one seems to be just what I was looking for - they don't bother you with all these useless emails and phone calls, they just let you trade - and it's excellent.
