Williams has written a 2nd edition to his original book, Trading Chaos, which was just released a few months ago. I have the book, and like it very much.
The 2nd edition is a complete rewrite, NOT an update. In it, Williams says that the other two previous books, Trading Chaos 1st edition and New Trading Dimensions, are no longer valid due to market changes. He also says that the new methodologies in the 2nd edition are much more profitable. If you want to learn how to use the Bill Williams indicators, it would be best to get the most recent book, just published in the Spring of 2004. Get the 2nd edition!
The best price I found was at traderslibrary.com.
By the way, the best trading book I've ever read was FREE, given away by one of the world's greatest traders who has more than 3 decades of experience. It is called, "Phantom's Gift". You can read it on the website of Futures Magazine. His Rules 1, 2, and 3 will make you a millionaire.
Good luck. There are some great ideas in these books. Fractals and using them to add on positions was worth 10X the price of the book. See Wise Man #3 in 2nd edition for details.
There was also some great material on the mind game. Say "hello" to Joe Gremlin for me!
