What are fractals?
Fractal geometry, defined by mathematician Benoit Mandelbrot, is a geometric figure that can be decomposed into parts, each one of these parts identical on a smaller scale to the original figure. However, the “fractal finance” applied to technical analysis is a geometric pattern that can be observed regardless of the time frame used, either 1 hour, 30, 15 or 1 minute. There are some books on this subject and one of the most popular is “Trading Chaos” that was written by Dr. Bill Williams. In this book, Dr. Williams entered two important concepts, the “Fractal UP” and “Down Fractal”, which can be used as support and resistance respectively. When both formations are crossed by the price, that indicate new levels for prices in both bull and bear markets.
The “Fractal Up” (it indicates a possible resistance), defined by Williams (Using a bar chart) is one pattern where the central bar has a maximum price that is greater than the maximum of the two bars to the right and higher than the maximum of the two bars on the left. On the other hand, the “Fractal Down” (it indicates a possible support) is one pattern where the central bar has a minimum price that is less than the minimum of the two bars to the right and less than minimum of two bars on the left. We can observe the ideal fractal in the image:
