Bests & Worsts Reviews from Amazon

After reading many reviews posted for this book, I became suspicious that some of these reviews were posted by the same person. I randomly investigated several the reviews & reviewers. What I found is that at least 4 of them had exactly two reviews and both of the reviews were for the same two books (this book and the author's other book, what a coincidence). For instance, T. Sonia (Hong Kong), Calvin Choy (Singapore), and zephyr "Dan" (California) are very likely the same person with different profiles, which can be changed. There are two other reviews that are just like that too. All of them gave 5 stars for both books lol. If you really want to read a true reviews, read those that are 3 stars or less. For instance, read Duane Phillips' and Don Catt's reviews. This book is basically a user manual for the author's trading software called ART. The software is selling for $2500.
