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.

One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over-the-counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney—across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.
