A new article by Sergei Shashev: Construction of Fractal Lines

Fractals are used by practically all traders. However, if you ask them what a fractal is, they will at best answer that it is an indicator in the Bill Williams' system. The more advanced traders will say that it is a sequence of 5 bars where, if the middle bar's High is higher than those of other bars in the sequence, it is an Up fractal and, if the middle bar's Low is lower than those of other bars, it is a Down fractal. As the phrase goes, "This is all I can tell about the war”.
