The authors have extensively researched the seasonal tendencies of virtually all major commodities going back as far as 1955. The result . . . over 50 empirically derived seasonal trades (on average, about one a week).
Each individual trade is provided with commentary and clear, concise, easy to follow rules that tell you when to get in and when to get out of each trade. Each trade is documented with results that would have been obtained each year for all the years studied.
The net result: each and every seasonal tendency traded by the authors' rules (for the entire period) would have been highly profitable.
[Note: the book comes with a separate update of 'Sure Thing Trades' from 1979 - 1995]
