I agree, read and learn all you can when first starting out with forex as well as open several
demo accounts at possible brokers that you may use. Most have demo accounts with their own platforms these days. This will allow you to get a feel for their software and platform.
I like Douglas as well as his other book - The Disciplined trader
Forex is hard work and a continual learning curve, dont let anyone else tell you otherwise.
You won't become wealthy overnight (possible if you bet your lifesavings with 100:1 leverage and get lucky before NFP) it is the slow and steady that win the race here.
