This book is a huge disappointment. Bought it based on other reviews and recos from trading forums. To start with, the author's writing style is so 1950s that it hurts. The charts (what few ones there are) have handwritten notes. Most of the trading advice consists of trading 101 cliches such as "let your winners run and cut your losses short". To be fair, when this was written, trading commodities was not a widely undertaken endeavour by non-professional traders so perhaps that can be forgiven.
A glaring error repeated throughout the book occurs when the author suggests that by earning 30% per month, which presumably his book will help you do (hah!), it is possible to earn 360% per year. Perhaps compound interest (along with electricity and the automobile) had not yet been discovered as of the publication date, but a 30% return each month compounds to an annual return of 2,330%...! Such innumeracy is quite frankly astounding for the author of a book on finance. The very best hedge fund managers, who manage billions in investor capital, are lucky to return 30% per year. This guy is a joke.
The author repeats again and again that the best way to invest is in a "special situation" which may only occur once a month. Besides never bothering to explain exactly what this "special situation" is, despite constantly alluding to them, he also never tells you how to find one.
Bottom line, terrible book, terrible writing style. Don't be a sucker, if the title sounds too good to be true, it probably is.
