Detrended Price Oscillator (DPO):
Detrended Price Oscillator removes the trend effect of price movement. This simplifies the process of finding out cycles and overbought/oversold levels.
Long-term cycles consist of several shorter cycles. Analyzing such short components helps to define crucial moments of the cycle's development. DPO gives a chance to eliminate the influence on prices of long-term cycles. To calculate DPO you should take a certain period. Remove cycles that are longer than the chosen period from price dynamics, and leave shorter cycles. Half of the cycle's length is used for smoothing. We recommend using a period of 21 or less.
The bounds (overbought/oversold levels) come from the history of previous behavior of prices. It is recommended to stand in a long position if DPO first falls below the resale level and then gets above it. Crossing of the zero point from above followed by a rise above that level is also a signal for opening a long position. Everything is vice versa for short positions.

Detrended Price Oscillator
The Detrended Price Oscillator attempts to filter out trend in order to focus
on the underlying cycles of price movement. To accomplish this, the moving
average (generally 14-period) becomes a straight line and price variation above
and below the moving average becomes the Price Oscillator. The Detrended Price
Oscillator technical indicator can show overbought or oversold levels and can
also create buy and sell signals.

Interpreting the Detrended Price Oscillator
When the Detrended Price Oscillator is above the zero line, it means that
price is above its moving average, a bullish sign. Similarly, when the Detrended
Price Oscillator is below the zero line, it means that price is below its moving
average, a bearish sign. There are two interpretations of buy and sell
