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.
More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. When a deal is finalized, this is known as a "spot deal". It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement.
