How far back should I start from? As a youngin', I used to go to birthdays, just about every weekend as a magician. This went on for about 11 years, then I retired from magic at age 21. I became a Psychologist and helped insurance companies choose the jury for high stakes cases. That was interesting, but not so much fun. Then I found forex. This is fun. I would be happy to show you how I trade for a living. Spend time on this forum, there is a wealth of information here for you. I am here to help as well as many of my trading buddies from around the globe. Happy Trading! Trading, talking about trading, traveling and surfing!
