The Intermarket analysis is poorly covered in current literature, with few books of historical data and boring details.
Instead in this book the Author, who has mastered the Intermarket analysis, shares many discoveries, and helps the reader to develop indicators and trading strategies.
This book makes it easier to understand today markets, and I suggest it for both long and short term trading. It is not for fiction traders who bet on markets direction, but for people really trading their own accounts, studying a lot of technical analysis and pondering experts ideas.
Even this book is very useful for MetaStock (MS) users to design (or improving their) trading systems, even you aren't the best programmers. Also users of other technical analysis software can develop trading strategies, because in the Appendix there is the MS code for all the systems described, and the Excel spreadsheets for the other methods (for example the asset allocation method).
Reading this book grow up your fever to go to your pc for studying the correlations Author disclosed, and testing the trading strategies he explains !
Minuses: discussion on fuzzy logic and genetic algorithms are very introductory (but these are very specific topics). Author limited his Intermarket analysis to major markets, and not all exchange products are covered.
Pluses: the best book on the subject I ever red : the Intermarket analysis is well explained. The Author insights help to really make money in trading today markets. Good value for price : many systems described would cost hundred dollars to buy !
