This book focuses on intramarket trading rountines, by which I mean using one market to estimate the behavior of another before it happens. This idea was first introduced by John Murphy. However, he did not, at that time, present trading paradigms.
In my opinion, Ruggerio does not intend this book to be a complete exposition on intermarket trading systems, much less on "cybernetic trading strategies." He does present enough examples to show the way to develop your own, presumably more sophisticated intermarket systems. Ruggerio really doesn't attempt to program and use technical analysis, nor does he claim to. His discussion of neural nets and genetic algorithms are very introductory. These are, however, topics that require at least a book each, absent a very good background by the reader.
In short, this is a pretty decent idea book, or rather approach book dealing with computer driven trading systems which use intermarket analysis. Personally, I think it's a useful book, even though I don't use the approach: I'm more technically oriented.
If you are looking for a definitive approach to using modern math to make a zillion dollars while you watch basketball, this isn't the book. Of course, you won't find that book, but that is a different discussion. Don't go here for neural nets or genetic algorithms, either. See Goldman(?) for the latter. I'm no help for the former.
I should note that this book is aimed at commodity traders. Stock traders can make use of the techniques by translating "commodity name" to "sector name," assuming one uses sector analysis.
