Hello Rien,Going back to your suggestion for circumventing the "flaw", from a curiosity point of view, I tried to visualise your 5-step procedure but somehow I fail to "get it". I mean, it does not appear to solve the basic problem I addressed.In the first two steps(igoring the SAFE for now) the equity value returns to its orginal value y1...(at the start y1=pc1 also)y3=y1+(pc1-y2)=y1 pc2=pc1 as you suggest ----->zero buy signal. OK!Your next step is "fuzzy" to me. You calculate "next prices" using pc1=pc2, OK some prive differentials result..I assume you use the SAFE idea for that. But now you raise the pc as usual pc3=pc2 +1/2(next buy advice) and as I see it there is again a buy-signal as pc3-y3 is not zero! The buy-advice is again 1/2 of the next calculated buy, and his is exactly the problem I addressed.I think I see what is happening: After you have bought the fist lot and did not update the pc you calcuated a "next buy" signal and substituted that for the (pc-y) criterion. Then after updating the pc "as usual" you simply ignore the new buy-signal that results and stick to the calculated "next buy" you calculated. I would agree that this will stop you from buying in on the new buy-signal but the methods appears to be more of a "fudging-approach" rather than anything else. One might as wel simply use the original method and ignore the residue Buy-signal and only buy if the stock price has dropped and then implement the buy as advised, with again ignoring the residue buy-signal.After having reviewed the many discussions I have concluded, as I have said before, that using the pc-corrector pc=y eacht time a buy or a sell is activated appears to be the most effective solution. With selecting an appropriate "aggression" for the buy and sell seperately we can tune the AIM-behaviour as we see fit. With the addition of an appropriate Resistance for the Buy and Sell activity we can "time" the action so that a sell-signal on a trend-reversal is not actuated too soon(creating a delay-factor on rising prices).I think that with this I have reached the end of my quest for a simple and convenient Advice Generator that gives a zero buy-sell signal after every buy and sell. It would appear unnecessary for me to dwell on this issue much longer.I hope the discussions have provided more insight into the possibilities for AIMers. At the least I have come to recognize the merit of the 1/2buy pc-corrector on the bottom of a Dip...the Residue Buy at that point produces a delay for the selling off of the equity. The equity value has to rise at least to above the previous 1/2Buy amount in order to produce a sell signal. I agree that this is a positive featue of pc2=pc1+1/2Buy pc-corrector.Is there more to say?Conrad
