## Detrended Price Oscillator (DPO)

### Description

The Detrended Price Oscillator, by Gerald Appel, attempts to eliminate the long-term trends in prices by using a displaced moving average so it does not react to the most current price action. This allows the indicator to show intermediate overbought and oversold levels effectively

### Formula

$DPO = Close - MA_{n}\;of\;\left ( \frac{n}{2}+1 \right )\;periods\;ago$
