Query: Definitely not the complete guide.

This book provides little more than a pedestrian introduction to commodity spreads. The book includes quite a bit of information that would best be left to other tomes: introduction to least squares regression (you would do better to use a Statistics 101 book), development of a trading system (get a book on trading systems/methods...), etc. The only material that I thought carried unique insight was the brief portion on EuroDollar Futures. There was only shallow discussion on analysis of futures patterns, or market tendencies. This book would only be useful if you know NOTHING about spreads.
