Query: This book is an advertisement.

This book is not a book, it is an advertisement for Cynthia Kase's "proprietary indicators". The content is a demonstration of how "well" Ms Kase can paper trade using these indicators, followed by sketchy details of how the indicators may be used. No information whatever on how to calculate or use these yourself. Having already paid for the book, you may wish to take up Ms Kase's offer to allow use of these proprietary indicators after paying $1000US. Or then again, perhaps not.
