I think if Confidence versus Knowledge then I would prefer to Knowledge because I think Confidence is nothing without Knowledge but Confidence also plays an important role in Forex Trading. and Ok, this is a good question for me, the best information for any dealer, from information that can be made by any dealer, this is the best for any dealer, certain confidence is the best for every forex laler dehanks, from that information is good enough for any dealer. thank you forex members.
