Demo Account: Although demo accounts attempt to replicate real markets, they operate in a simulated market environment. As such, there are key differences that distinguish them from real accounts; including but not limited to, the lack of dependence on real-time market liquidity, a delay in pricing, and the availability of some products which may not be tradable on live accounts. The operational capabilities when executing orders in a demo environment may result in atypically, expedited transactions; lack of rejected orders; and/or the absence of slippage. There may be instances where margin requirements differ from those of live accounts as updates to demo accounts may not always coincide with those of real accounts.
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.
In situations of economic uncertainty like we are facing right now, the best defense for your hard earned dollars is to be as well-informed and educated as you possibly can. Following the news that impact the markets, researching companies and following the markets should be a full-time job (unless you want to risk your money... you are probably better of at a roulette table).
