The indicator shows the current reference prices of the current market state. This is necessary for determining flat market.
The indicator is based on fractal smoothing (known as FRAMA http://kroufr.ru/content/view/6138/81/ - in Russian) having a discrete filter that removes minor price movements when the relative flat movement does not exceed the square of the interval dimension in the specified interval.
