Unlike stock markets, which can trace their roots back centuries, the forex market as we understand it today is a truly new market. Of course, in its most basic sense - that of people converting one currency to another for financial advantage - forex has been around since nations began minting currencies. But the modern forex markets are a modern invention. After the accord at Bretton Woods in 1971, more major currencies were allowed to float freely against one another. The values of individual currencies vary, which has given rise to the need for foreign exchange services and trading.
Interesting. Rob is one high-profile forex 'guru' I've been loosely following for several years, and he seems to flit from system to system. For example, a few years back he was very enthusiastic about a system he called the Hopper (which was little more than a MACD crossover) which he was touting with his ladyfriend Jennifer Thornburg (who likes to write articles about Sex and Trading, btw). More recently Rob's been promoting EAs, including some that take profit quickly while allowing floating losses to snowball. Given all of this, I've never bought anything that he's been offering, and I've found it difficult to take him completely seriously.
