Now a days there are many guides released in the marketplace for studying currency dealing. And from internet we get all the things and also about the currency dealing record. But in my view the best guide is our past deals and failures which we have made previously. many things that can make us have a good knowledge about forex is important in my opinion we should have a spirit of learning and it is important to always practice on a demo account because later we can get a good experience so they can learn from that experience.
