The markets can offer a real challenge. The financial markets seemed to offer precisely the challenge that I was looking for because they require both quantitative and intuitive skills. When I left university, the one book on the financial markets I had ever read was written by an efficient-markets fundamentalist. Therefore, that was the view I immediately adopted. That's not unusual.
Most technicians start out with a fundamentalist background.
It's funny in retrospect, because my approach to the markets is the opposite now. I remember one of my first job interviews turned out to be for the position of technical analyst. Thankfully, this ignorant phase was short-lived. A healthy dose of reality soon put a stop to it. A bit of both.
