I've seen this video. Looks great but if you reverse engineer the dates with an ephemeris you find that the cycle he is showing is a repetition of a fixed heliocentric angle of 0.21° between Saturn and Uranus. This made me wonder if this kind of fixed cycles with an orb of +/-1 day and inversions will not always give some kind of results that look good on a chart but have no value in actual trading. On the other hand it made me think of the cycles that BA from ganntrade6 is rambling about in his videos. This kind of cycles are also talked about in the Adventure of a Cycle Hunter book series.
