The Detrended Price Oscillator (DPO): How to Spot Cycles and Remove Market Noise
The Detrended Price Oscillator (DPO) is a unique technical indicator designed to remove long-term trends from price data, making it easier to identify short-term price cycles. Unlike other oscillators that focus on momentum, the DPO helps traders spot market peaks, bottoms, and cyclical trends.
In this guide, we’ll break down how the DPO works, how to use it effectively, and the best DPO trading strategies.
What Is the Detrended Price Oscillator?
The DPO is used to filter out longer-term trends to help traders focus on shorter-term price cycles. It shifts price action back in time, allowing traders to see when prices deviate from their average trend.
Key DPO Features:
- Removes long-term trends to highlight short-term price movements.
- Works well in cycle-based markets, such as commodities and forex.
- Identifies overbought and oversold conditions more clearly than moving averages.
How the DPO Is Calculated
The DPO formula is based on a Simple Moving Average (SMA):
[
DPO = \text{Price} – SMA(\text{n-period shifted back})
]
Where:
- SMA(n) is the Simple Moving Average of the asset over n periods.
- The shift is calculated as (n / 2) + 1, which moves the SMA back to align with past price action.
The default DPO setting is 20 periods, but traders can adjust it for shorter or longer cycles.
How to Use the DPO in Trading
Identifying Overbought and Oversold Conditions
- Sell when the DPO reaches a peak and starts turning downward.
- Buy when the DPO reaches a low and starts turning upward.
DPO Cycle Trading Strategy
- Look for repeating peaks and troughs in the DPO to predict future price cycles.
- Enter trades when the DPO aligns with historical cycle highs or lows.
DPO Trend Confirmation
- If the DPO is consistently positive, the trend is bullish.
- If the DPO is consistently negative, the trend is bearish.
Best DPO Trading Strategies
DPO + Moving Average Strategy
- Buy when the DPO crosses above zero and price is above the 50-day SMA.
- Sell when the DPO crosses below zero and price is below the 50-day SMA.
DPO + RSI Strategy
- Buy when the DPO is turning upward from a cycle low and RSI is below 30 (oversold).
- Sell when the DPO is turning downward from a cycle high and RSI is above 70 (overbought).
DPO + MACD Strategy
- Use MACD crossovers to confirm DPO signals.
- If the DPO is rising and MACD is bullish → Strong buy signal.
- If the DPO is falling and MACD is bearish → Strong sell signal.
Best DPO Settings for Different Trading Styles
- Day Trading: 10-period DPO for detecting short-term cycles.
- Swing Trading: 20-period DPO (default setting) for balanced trend filtering.
- Long-Term Investing: 40-period DPO for analyzing major price cycles.
Common DPO Mistakes to Avoid
❌ Using DPO in strong trending markets – The DPO is best for range-bound or cyclical markets.
❌ Ignoring other indicators – Always confirm DPO signals with RSI, MACD, or trend analysis.
❌ Expecting real-time signals – The DPO is a lagging indicator and should be used for historical cycle analysis.
Final Thoughts – Should You Use the DPO?
The Detrended Price Oscillator is a valuable tool for spotting short-term price cycles, identifying overbought/oversold conditions, and filtering out long-term trends. When combined with moving averages, RSI, or MACD, it helps improve trade accuracy and market timing.
