Query: oh yeah? trade this!

Take the sections on price structure and open interest - throw the rest out if you like. You'll still have the most valuable trading book I've seen written to date. I see ten other reviews here, and only a couple mention OI's significance - mostly in passing. Very sad. Open interest's relationship with price action on a few levels deserves at least a few years of study, although it won't take you nearly that long for you to at least appreciate its importance the way it's presented in this book. This was the first market book I paid for as a market newbie in May '88. I still have fond memories of this basic OI move for OJ may 88, COP aug 88, PA oct 88, CT fall 88, COF dec 88, HO and HU summer 89. Try telling me again how worthless this book is...quit criticizing and study harder. The answers exist and much of it is humanly achievable. You're given a small morsel of it here and yet I see nothing but a ho hum response. That in itself is an interesting market lesson.
