For me, I have not studied forex from a special person. When I just learned forex trading by internet.itu is a forum that shows me what is Forex. And that is the forum that leads me to live in the forex market now. I think this forum is probably my best teacher to teach forex knowledge, share trading strategies, even show me some trading signal there. and To be fair I would say the demo account is my forex guru because I am learning every basics of it and I am doing pretty well and I would advise any beginner to use a demo account properly for a very important part of forex.
