Her computer runs simulations to determine what period for %D calculations yielded the best results. She was not interested in the profitability per se, just what period works best. Has anyone written a formula in MetaStock that replicates her caclulations? I.e., that will vary the period of %D to find what period yields the highest profitability. I tried doing it a few times, but I know I have the wrong answer. This book is part of the CMT Level 3 so I have a feeling I am not the only one asking this question.... Thanks in advance!
