The book cover jacket states,"Look into this book for: A custom composite index formula that will diverge against RSI.." This is also stated on the back cover and with front cover chart examples. Unfortunately the author reneges on this claim in the body of this book only to show the potential of the indicator and direct the reader to her web site that charges $5500.00 for a few select traders to whom she will reveal this information. I have no problem with technicians keeping their proprietary studies to themselves, but this book deceitfully makes an offer, accepts payment and does not deliver. This seems to me like a deceptive marketing ploy that mars what is an obviously perceptive and in-depth study of technical indicators in the futures industry. It is suprising that the renowned George C. Lane would give this his Foreward and support.
