History repeated
Technical analysis and study of market dynamics is closely related to the study of human psychology. Thus, the graphical price models are identified and classified in the last hundred years illustrates the core characteristics of the psychological state of the market. First of all, they show the current mood prevailing in the market, whether bullish or bearish. Since this model works in the past, we have reason to suspect that they will work in the future, because they are based on human psychology which remains virtually unchaged for years. We can reword last theorem - the story repeats itself - in a slightly different way: the key to understanding the future lies in the study of the past.
