I have been trading forex intermittantly for about 18 months - and gradually improving. Over the years I have taken various courses to learn to trade but never felt I had enough background knowledge to begin. At the moment I mix the trading with other work - but my goal, like many, is to eventually just trade for a living.
Most of my recent improvements are via the kindness of people helping and sharing their insights and experience on FF.
From what I have learnt to date simple systems, good money management and discipline are the keys.
