Looks like a 2020/hindsight fibo casting, with fancy labels. I could do the same thing on any chart and look the genius. The key question is...What does that chart tell the author the market will do TOMORROW? It tells nothing, of course, so it is almost useless.
Whatever they call it, it is quite silly. It is very fancy on a chart, looking backwards. Where does price go, TOMORROW, on the Murray math? I can certainly take a guess. It will go between 1/8th and 15/8th in either direction tomorrow. Add an extra 8th, because Trump and Powell are still alive.
