On the picture in https://www.elitetrader.com/et/thre...ith-cycle-analysis.335321/page-3#post-4914727 the vertical lines are on approximate full moon dates (6/17/2019 and 7/16/2019). So the method might be a variation of the Delta Phenomenon.
Yes, my way, there are no inversions. And more accurate. I discovered and fixed the flaws in Sloman's method. Delta Society couldn't care less. Wilder has Alzheimer's. If you really want to buy their book, never buy it new. Pay a little as possible as it's really worthless.
Got out of crude for a loss. I've got to stick to one market and it's the SP500. Now short. My cycle analysis shown. Next low due in late August.
This approach seems like a graphical rehash of Fourier transformations, trying to identify the cycle of a market. The conclusion of those analysis was that those cycle times are not stable, but fluctuate, and thus difficult to capture properly. You may want to try grains: ZC, ZW, ZS.
