How would you define the fractal concept? Is it useful in understanding the Elliott wave principle?

The fractal aspect of trading is simple, if one understands the "entity-within-entity" concept. They are interconnected; each of them is related to the next one by shape, size, complexity and interlinked mechanisms. In trading, all this is resumed to using multiple time frames, knowing the composition of a pattern with their internal waves, which in turn have their subwaves. Understanding the degree of dependence for each degree of entity becomes here essential. The fractal concept is also implied into the impulsivity/correction duality for every current movement. These elements are bound among them with various functionality means, well represented in Elliott wave concept: proportionality, equality, alternation, action and reaction mechanisms and others.
