The forum is playing on probablities, not true edges.You are gamblers.
In watching Fisher's seminar videos from way back in 2002-2005, he never says just buy every A-up and you'll become profitable. As a matter of fact, if you watch the first seminar video he did, literally the first sentence out of his mouth when he stood at the podium was "if you are here today because you think I am going to teach you the holy grail of trading, you are wrong." He talked about ACD being one piece of the puzzle that "when overlaid with other things can help you identify good risk reward opportunities and knowing when to press the gas pedal vs when to press the brake."
And that has been my experience when applying it to my intraday trading...does Fisher's stuff allow me to print money? No...Does it force me to confront my bullsh*t lies I tell myself when I have a losing position on that is grinding against me that I think "has to turn around in my favor." Yes, absolutely. So in that sense, on an intraday basis when markets are flying - it helps keep me more objective, which has helped me reduce the size of my losing trades greatly, thus improving profitability.
