Hello KK
First of all, Bill Williams's books have nothing to do with Chaos Theory.For a proper introduction into using Chaos Theory in Markets I would suggest Mandelbrot's Misbehavior of Markets.
Mr.Williams is just another vendor satisfying the gullibility of newbie traders that plugging in Modified MACDs and MAs will somehow make them tonnes of money or atleast a few K.Gs of it.Remember the old California gold rush? The only people who made money were the ones selling spades and maps.
Just picture this.In an Operating Theatre in a hospital, Doctors yelling at one another."Hey, I just saw the 10 period MA of heart beat cross the 21 period MA, lets give him shock therapy" or "The MACD of his Blood Pressure is looking bearish, lemme give him a dose of insulin".
I remember meeting a 'Chaos Trader' a year back, his mentor was Sukhani or so he said.He was adamant about the Gators and Alligators and would describe the Slope of his Trading System Equity Curve as if the cheque was already handed to him.Nowadays he is back into IT, coding projects more of a different variety.
Just my 2 cents
