Excellente! book published in 1986 by the New York Institute of Finance (NYIF). The NYIF is the organization that provides training for various kinds of brokers. Anyone can take these courses by correspondence and if you pass the test at the end you are probably as knowledgible about stocks or commodities as any broker sales person, licensed or not. This book, 556 indexed pages, analyzes the price/volume action of commodities attempting to improve predictability. It might supplement a more fundamentals analysis but, of course, fund sponsorship knowledge and inside info are the most reliable price predictors.. Recent years (and probably since the early days) have seen a number of price manipulative groups and indiviuals (only a handful jailed, unfortunately) so the analysis may be faulty. However, it is worthwhile to know terms and trends others in the herd are watching. Book has owner name at bottom of flysheet, otherwise the book is in like-new spotless, bright condition with not even a page corner bend. Excellent DJ with minor edgewear.
