I learned from Larry Pesavento this AM that Bill Erman passed away (he was in his 90's). Larry knew Bill and thought highly of him and his work. I was acquainted with Bill and talked with him a number of occasions about his work and life. Bill still had family in Kansas City and his uncle's scrap and metal recycling business is about a mile away from me fronting the Kansas river.
Bill is the creator of Ermanometry, which applied geometry, specifically log spiral geometry to the markets in order to anticipate inflection dates. I've used Erman's work for years and find it a wonderful confirming signal, and when it hits in alignment with other signals there is much more confidence in the trade.
Here are two Ermanometry charts below. Larry P posted the first this am on TFNN from one of Bill's colleagues that was created using Bill's techniques which Id's 8/23/2016 as a major long term top in the Dow. (I don't have a good copy as my snipping tool provided a grainy version).
In addition to that chart which goes back almost 100 years, below is my chart of the Dow with recent shorter term Ermanometry inflection points noted with colored dots which were created using the geometry of Bill Erman that I coded into Trade Station for use on Daily Charts (Coles wrote the orginal software for hourly charts and it is available at http://traders.com/D...adersTips.html)(I posted the Daily Ermanometry code in the Trade Station support forum)
We've lost a true genius in analyzing the market
