This is the first time I've commented on a book here on Amazon before reading it.What strikes me is that the reviews can be broken up into two camps:- trading professionals working in the industry, who have the indicators already programmed on their terminals, and who have the incentive to use them- trading amateurs, either complaining about the poor structure, layout or grammer used in the book, or who don't have the means or the ability to program the indicators for themselves.With this in mind I ordered the book, figuring that I would much rather trade on the same side as the professionals. I gave it four stars so as not to unduly influence the book's current rating.
