Mr. weinstein has written a very imformative book chock full of technical knowledge that he's very ably translated into layman's terms. Also, unlike some of the big writers in this field, his advice is totally consistant with no ambiguity and no preening ego. He tries to make a science of charting, eliminating all emotion in the trading process. He stresses discipline with trailing stops etc. All of this leads to a system that still won't let you pick winners more than 50% of the time but WILL get you out of bad picks quickly and let you safely ride the winners up. If you use his system with discipline you will never buy at the very bottom and you'll never sell out at the very top - but you'll make money and you'll NEVER lose your shirt.
