a number in the Fibonacci sequence
Good to see a point of view backed up by hard science.
Although to be fair, it's not any more or less outrageous than a lot of other economic scienctificism.
R. N. Elliott's analysis of the mathematical properties of waves and patterns eventually led him to conclude that "The Fibonacci Summation Series is the basis of The Wave Principle."[1] Numbers from the Fibonacci sequence surface repeatedly in Elliott wave structures, including motive waves (1, 3, 5), a single full cycle (5 up, 3 down = 8 waves), and the completed motive (89 waves) and corrective (55 waves) patterns. Elliott developed his market model before he realized that it reflects the Fibonacci sequence. "When I discovered The Wave Principle action of market trends, I had never heard of either the Fibonacci Series or the Pythagorean Diagram."[1]
It does not say who the critics are, but the second critique sounds like mainstream economists.
Indeed, both critiques sound like mainstream economists, who are often a bit tone-deaf to that kind of internal contradiction.
BTW, Dan Brown would be a brilliant technical analyst. An ability to generate fictions about elaborate patterns with a very thin surface veneer of plausibility to persuade large numbers of the gullible that the patterns are real world phenomena - why, that's just the job description for a technical analyst. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
