A Detrended Price Oscillator is a technical analysis indicator used to analyze the price of a financial instrument. It is a type of momentum indicator that shows the relationship between two moving averages of a security's price, with the aim of identifying potential overbought and oversold conditions. The indicator is calculated by subtracting the longer-term moving average from the shorter-term moving average, and then plotting the resulting difference as a line on a chart. The idea behind the indicator is that when the line is above zero, the security's price is relatively high compared to its moving averages, and may be considered overbought. Conversely, when the line is below zero, the security's price is relatively low compared to its moving averages, and may be considered oversold.
