if you study from a mentor just for additional knowledge, that's fine, but if all trading methods depend entirely on the mentor later, bro.. we are in trouble if we depend entirely on the mentor, we must understand and practice the ocean of forex knowledge because I said earlier forex is fair and unique. so if there are only 2 choices, I'd better learn on my own, no more than 2.5 years, usually a self-taught trader will be able to find a comfortable and profitable trading system that suits his style.
