The concept of automated Forex trading versus Forex trading signals is a bit of a misnomer. It's not a matter of either/or, really. It comes down to a matter of preference, need, and knowledge. It also concerns the manner and amount of control the Forex trader wants to maintain. Yes, they are both easy to use and the learning curve is a shallow one. But that doesn't mean it is restricted to the beginner. Some of the most experienced people will use the simplest tools. One thing has nothing to do with the other.
It goes to follow that automated Forex trading would be for the totally inexperienced Forex trader while using Forex trading signals would be more conducive to traders with a certain amount of experience. Neither situation is necessarily true. An experienced trader might want to use a robot to track its accuracy and test his own ability to tweak and program it. An experienced Forex trader might want to use signals to check or test his own technical expertise.
On the other side of the spectrum, both systems could be used for the uninitiated. Automated Forex trading allows the user hands-free trading, however using Forex trading signals is not much more complicated than that. Entry, exit, and stop-loss points are given, and all the Forex trader has to do is enter the trades on the computer. Not very complicated at all in either case.
Both systems should be viewed as to what they are; tools to be used when trading Forex. There isn't the case of one being better than the other. They are different and will ultimately depend on the Forex trader being comfortable with the system they choose. In both cases, it is important to research both systems and the one you might want to use. The supplier of either system is responsible for its performance and that has to be taken into account.
What must be minded, is that neither the automated Forex trading system or the Forex trading signals system is a fool-proof method or a get-rich-quick process. Ultimately, it is going to take work on the part of the Forex trader. There is just no getting around that.
