This is the realm of Courtney D. Smith. When you say textbook, do you mean read boring. This brings to mind 3 books. Two of which I read in the public library before I bought them. Futures Spread Trading: The Complete Guide !by Courtney D. Smith (Hardcover - May 2000)Courtney Smith's textbook is specifically and comprehensive about spreads. His whole book is about spreads and nothing but spreads. Probably the most useful from the fundamental perspective. A Complete Guide to the Futures Markets: Fundamental Analysis, Technical Analysis, Trading, Spreads, and Options! by Jack D. Schwager (Author) (Hardcover - June 1984)Schwager's textbooks while not specifically about spreads are comprehensive and complete about futures. This book has a small section about trading commodity futures spreads. Seasonality: Systems, Strategies, and Signals ! by Jake Bernstein (Author) (Hardcover - April 1998)Jake is a trader but this is not a trading book like Rossâs Spreads and Seasonals!. Jake explains how Seasonal patterns are the heart of consistent profits in trading spreads. As long as summer follows winter, we will have tradable cycles. Those are the textbooks but you should include Trade Your Way to Financial Freedom ! by Van K. Tharp,Tharp is about Winning. Chapter 5 has a section on Spreading as well as Seasonal Tendencies.
