I made a mistake in my post before. The histogram bar with the highest count was for 0.538637553686026 <= ratio < 0.551775054995441. The bar close to 0.618 had a slightly lower count. For something with finer granularity, Here, the intervals 0.499976170943578 <= ratio < 0.50010674711776 and...

I calculated prices waves using the method in this post for 27 ETFs (SPY QQQ IWM XLF XLE XLI DIA XLV XLK XLU XLY XLP XLB MDY SPYG SPYV SPTM SLYV TLT EFA EEM MDY EWW EWM EWG EWS GLD) on 18-22 years of daily prices adjusted for splits and dividends. Then I plotted the ratio of the price swing of...

It looks like you are saying Fibonacci ratios sometimes work when drawn after-the-fact to fit some part of the price movement.:)

This is in response to something @stochastix posted but deleted (it's always possible I imagined that too:)). That code listing described the genetic optimization after other software created functions that model price movement like: y_hi = 110.319160461426 - 0.0421270467340946 * x +...

Here are examples of how I've tried some ideas using genetic algorithms and genetic programming. https://www.elitetrader.com/et/threads/in-one-sentence-what-is-your-edge-for-2019.329802/page-8#post-4809209...
