Hi almanger V wave and I wave are basically the same thing but the I wave became propietary when Tom became a professional. Both were developed to answer when is the best time to start an account ( yesterday ) by altering how much cash to start with. If and that is a big if, you are going to use Vealies to keep from having too much cash after a long bull market, answer this question first. When DO you want to be holding lots of cash? Um after a long bull market right? I would be more inclined to use a trailing stop and keep increasing the shares I am willing to buy based on AIM TOOFUZZY
