The "bible" on Elliot wave theory is: "Elliott Wave Principle : Key to Market Behavior" by Robert R. Prechter Jr., A. J. Frost amazon: http://www.amazon.com/exec/obidos/A...2/sr=2-1/ref=aps_sr_b_1_1/102-0823592-4106521 That being said: I never found Elliott wave theory useful. For each rule they have multiple exceptions, and I was never able to codify any of the principles in a way that was productive consistient profitable results. As with everything else in trading, I'm sure that someone else has made a fortune off of Elliott Wave methods .. it just never worked for me.
