Demarker indicator
DeMarker is an author's indicator named after its creator, well-known trader and technical analysis guru Thomas DeMark. This oscillator evaluates the position of current prices in relation to the previous period, helps to determine the state of the market and find places for a possible reversal of the current trend. The indicator is calculated in a separate window under the price chart.
DeMarker is a normalized oscillator: its values range from 0% to 100%, which are indicated in the indicator window as 0 and 1. Unlike other oscillators, DeMarker pays more attention not to closing prices, but to intermediate extremes (highs and lows). The indicator calculation algorithm compares the current highs and lows on the price chart with the extreme values of the previous period.
