Don and I discussed a lot of AIM ideas at the time he was active on this Forum. After that I kept in touch with him for quite some time as one of his AIM-derivatives was essentially identical to what I used. He introduced that version in an AIM Completion here. Don's Multiplying Factors were structured to concentrate the Buys and the Sells close to the limits of the Trading Range. . a concept we explored here again with various the Ladder Structures that Clive (Is7550) and I proposed and "tinkered" with. . .In my view Don was the inventor of that too.
I especially remember his MACRO Filter which he asked me to test and comment on before he presented it on the Forum here. Quite a prolific Idea Man he was!
