Detrended Price Oscillator Strategy Backtest

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.
