This book pops up quite frequently as recommended reading on ET. Are any of you utilizing strategies based, loosely or directly, from this book. Just wondering whether I should plunk down cash for a copy...Expanding my trading library, and I don't want to waste $$ on one of the many trading books that are now irrelevant, counterproductive, or just plain useless. Perhaps any strategy, once published for the masses, is automatically rendered irrelevant. I hope not. Any thoughts?
