Rob Booker is a forex seminar entertainer, a forex "systems" marketer and he is not a successful trader. I can say this from plenty of personal experience: I attended two of his seminars, co-taught another one with him in Canada, and am mentioned in his book. Once Rob held a contest to see who could submit the most profitable system. A guy wrote an elaborate description of a "winning system" and submitted it, knowing full well that it was a system that was a guaranteed loser. Rob awarded him first place, lol, and never tested the system! Rob makes nearly all of his (big) money from selling systems-of-the-month (stuff you can easily find online.) He has not been seen on FF since professional trader Phil McGrew (look him up here--his posts are gold) made him his "buddy" and would speak the truth whenever Rob would post. Stay far away from this clown.
There are actually three ways that institutions, corporations and individuals trade forex: the spot market, the forwards market and the futures market. The forex trading in the spot market always has been the largest market because it is the "underlying" real asset that the forwards and futures markets are based on. In the past, the futures market was the most popular venue for traders because it was available to individual investors for a longer period of time. However, with the advent of electronic trading and numerous forex brokers, the spot market has witnessed a huge surge in activity and now surpasses the futures market as the preferred trading market for individual investors and speculators. When people refer to the forex market, they usually are referring to the spot market. The forwards and futures markets tend to be more popular with companies that need to hedge their foreign exchange risks out to a specific date in the future.
