I've started to acquaint myself with every aspect of forex trading and the industry in general a few years ago. I still don't consider myself absolutely proficient but I'm far from where I've started, and start to feel comfortably with my knowledge. Of course there is still room for improvement. :-) I try to find a simple approach, but I'm also thinking about some kind of event driven trading, i.e. trading around news releases... or maybe the fundamental trading (longer term approach based on economic drivers) will be the one I should pursue, I'm not sure yet...
