Hello Pvisser,
I am a member of Forexoma, I joined just over 3 months ago. I don't think that there is a claim anywhere of 20% per month. Vahid does say that this sort of figure is achievable, but I'm sure that nowhere does he say that you will get this by following his signals.
The signals that he gives are ideal for newbies, those who are unable to stand the pain of inevitable drawdowns. They are good and show an overall profit, but they are unlikely to make you rich. If you just want a signals service, then I suggest that you look elsewhere.
The main focus with Forexoma is education. When I first joined, I felt overwhelmed by the information overload on Vahid's daily and weekend reports. Vahid's style is such that you will soon lose this feeling of being out of your comfort zone and will start to understand.
If you open Forexoma's homepage, you will see on the left the Forexoma Discussion Board. In this forum Vahid answers every question that a forum member asks. I post under my real name of Keith there. You can join this forum and ask any question that you like and Vahid will answer you. You can join the program and if you are not happy you can leave within one month and get your money back.
If you want education and to learn how to be a better trader, I can recommend Forexoma. If you just want a service to tell you when to enter and exit trades, then Forexoma is not for you. If you want a bit of both - it will probably suit you.
