Query: The Encyclopedia of Technical Market Indicators

I have been in Technical analysis for more than 4 years and have many books on the subject but of all the books I have "The Encyclopedia of Technical Market Indicators" is the most misguided title ever. Motivation for this statement is that the book is almost like an empty vessel. The author relates to numerous indicators and indicates how successful or unsuccessful they are but without explanations which make it difficult to comprehend. Also nowhere in the book does he indicate how these indicators should be used which, in my opinion, should be the essence of a book with this title. The author attempts to correct this on his website at: www.robertwcolby.com.
