I agree. it does get complicated. What I’ve realized is that there are really three different questions to ask when deciding how to tweak the AIM circuit, depending on the goal.First, do I want to determine the proper SAFE percentage for the buy or sell side? If so, then I need to decide at what price level I actually want a buy or sell trigger to occur. Second, do I want the price to drop by a certain percentage before buying, or rise by a certain percentage before selling? That’s a different adjustment from the SAFE percentage calculation itself. Or do I want to know the required price movement before AIM triggers a buy/sell based on a minimum order size? That requires yet another tweak. Each of these approaches changes the circuit differently. I ended up building separate AIM calculators in Excel for each scenario and use the 'goal seek' function to go thru the iterations to solve for the correct value. If I understand the book correctly, Mr. L recommended a minimum order size of around 5%–10% of SV. My take is that this was mainly to reduce transaction costs and meet minimum trade requirements back in those days. Today, with commissions being very low or even nonexistent, I’m not sure minimum buy orders matter as much anymore. Overall, I get the impression that Mr. L’s philosophy was more about consistently picking up small “gold nuggets” along the way rather than trying to hit a home run.
