The Detrend Price Osc indicator is similar to a moving average, in that it filters out trends in prices to more easily identify cycles. The indicator is an attempt to define cycles in a trend by drawing a moving average as a horizontal straight line and placing prices along the line according to their relation to a moving average. It provides a means of identifying underlying cycles not apparent when the moving average is viewed within a price chart. Cycles of a longer duration than the Length (number of bars used to calculate the Detrend Price Osc) are effectively filtered or removed by the oscillator.
