Quote from RCG Trader:
Livermore blew up because he did not have ACD, no way he would have blown up otherwise.
Also, Fish himself separates bias from signal, and the very first five minutes of the seminar, he states that ACD is meant to overlay what you already do as a trader, that would clearly indicate that a signal generator should be brought to the ACD party.
Not trying to be snippy, just sayin, it might not be a bad idea to look at system vs. method. ACD is not a system, it is a method.
Well, of course there is more than one way to make money trading. It just goes to show that the assumptions we bring to trading strategy development drive the final outcome. For me, I needed something that enabled me to identify the one price at which buying or selling is probabilistically-optimal and built toward that goal without even thinking there could be another way to approach it. When that one price is hit, no other confirmations are required. There are so many similarities between what I do and ACD, it's just surprising to me that Fisher didn't take that extra step to merge bias and signal.
