Personally i never and ever support to pay for learning about forum trading where there have a lot of resource in online. You can analysis by following these. There have thousand of above ebooks in internet to learn about forex and all are free. So why you will pay for that?
I guess its one way for newbie without money to save money cause as a newbie, another thing they don't want to worry about is pay for more stuff cause they're lacking funding. However, there are so many credible sources online that are free cause they make money via ads so we can rely on those for some info but its up to us to decide whether its worthy or credible.
