How Detrended Price Oscillator (DPO) In Trading?

9 minutes read

The Detrended Price Oscillator (DPO) is a technical analysis tool used by traders to identify and analyze price cycles in the financial markets. It helps traders understand the underlying price trend by removing the short-term fluctuations from the equation.

Unlike other oscillators that use moving averages or other trend-following indicators, the DPO focuses solely on the price action. It detrends the price by shifting a simple moving average (SMA) backward to position it in line with a specific point in time. This specific point is typically chosen as the midpoint of the selected time frame.

By detrending the price, the DPO filters out the shorter-term price movements, which can be noise or random fluctuations. It gives traders a clearer view of the longer-term trends and cycles that are not easily recognizable on a regular price chart.

The DPO then plots the resulting oscillator, which oscillates around a zero line. The distance between the oscillator and the zero line indicates the deviation of the price from its detrended average. Positive values indicate that the price is trading above its historical average, while negative values imply that the price is trading below the average.

Traders typically use the DPO to identify significant price cycles and trend reversals. When the DPO crosses above the zero line, it suggests that the price is in an uptrend or experiencing buying pressure. Conversely, when the DPO crosses below the zero line, it indicates a downtrend or selling pressure.

In addition to detecting trends and reversals, traders also use the DPO to identify overbought and oversold conditions. Extreme positive values above a certain threshold may suggest that the price is overbought, while extreme negative values below a certain threshold may suggest that the price is oversold.

It's important to note that the DPO is a lagging indicator as it relies on past price data to generate signals. Therefore, it is often used in combination with other technical analysis tools and indicators to confirm trading decisions.

Overall, the Detrended Price Oscillator provides traders with a useful perspective on price cycles and helps them make more informed trading decisions based on the underlying long-term trends.

What are the best timeframes to use for Detrended Price Oscillator (DPO) analysis?

The Detrended Price Oscillator (DPO) is a technical indicator used to identify cycles and overbought or oversold conditions in the market. The most commonly used timeframe for DPO analysis is the daily chart, but it can also be applied to other timeframes depending on your trading style and objectives. Here are some considerations:

  1. Daily Chart: The DPO on the daily chart is widely used by swing traders and longer-term investors. It helps identify major cycles and turning points in the market, providing a broader view of price trends.
  2. Weekly Chart: Traders who prefer a longer-term perspective often utilize the DPO on the weekly chart. This timeframe helps identify larger market cycles and trends, enabling traders to make more informed decisions about their positions.
  3. Intraday Charts: For day traders or those looking for shorter-term trading opportunities, using the DPO on intraday charts (such as 15-minute or 1-hour) can be beneficial. It helps identify shorter-term cycles and potential reversals during the trading day.

Remember that the choice of timeframe ultimately depends on your trading strategy, timeframe, and personal preferences. It's recommended to experiment with different timeframes to see which one aligns best with your trading style and objectives.

What is the mathematical formula behind Detrended Price Oscillator (DPO) calculation?

The Detrended Price Oscillator (DPO) is calculated by subtracting a simple moving average of the past prices from the current price. The formula for DPO is as follows:

DPO = Close price - n-day simple moving average


  • Close price is the closing price of the asset for a specific period.
  • n is the number of periods used to calculate the simple moving average.

The DPO calculation provides a way to remove the overall trend or cycle of the asset price, allowing traders and analysts to focus on shorter-term price movements.

How to use Detrended Price Oscillator (DPO) to determine trend direction?

To use the Detrended Price Oscillator (DPO) to determine trend direction, follow these steps:

  1. Plot the DPO on your price chart: Calculate the DPO by subtracting a moving average (usually a simple moving average) from the price data. The moving average used is typically a longer time period, such as a 20-day or 30-day moving average.
  2. Analyze the DPO values: Look for peaks and troughs in the DPO values. Peaks indicate potential downtrends, while troughs suggest possible uptrends.
  3. Identify zero-line crossovers: Pay attention to when the DPO crosses above or below the zero line. When the DPO crosses above the zero line, it may signal a bullish trend, and when it crosses below the zero line, it may indicate a bearish trend.
  4. Confirm trend direction with other indicators: While DPO is helpful in determining trend direction, it is advisable to use it in conjunction with other technical indicators or price action analysis for confirmation. For example, you can use trendlines, moving averages, or other oscillators to confirm the trend suggested by the DPO.
  5. Set your trading strategy: Once you have identified the trend direction using the DPO and confirmed it with other indicators, you can develop a trading strategy based on this information. For example, if the DPO indicates an uptrend, you may consider buying when the price pulls back to a support level and shows signs of bouncing.

Remember that no single indicator can provide 100% accuracy in determining trend direction. It is essential to use DPO in combination with other tools and analyze the overall market conditions before making trading decisions.

How to build a custom trading strategy using Detrended Price Oscillator (DPO)?

Building a custom trading strategy using the Detrended Price Oscillator (DPO) involves several steps. Here is a step-by-step guide to help you:

  1. Understand the Detrended Price Oscillator (DPO): The DPO is a technical indicator used to eliminate long-term trends from price data, allowing you to focus on shorter-term price movements. It helps identify cycles and potential turning points in a security's price.
  2. Define the trading rules: Determine the conditions under which you want to enter and exit trades based on the DPO. For example, you may want to enter a long trade when the DPO crosses above zero and exit when it crosses below zero. It's important to clearly define these rules before proceeding.
  3. Choose a time frame: Decide on the time frame you want to use for your DPO calculations. The choice of time frame depends on your trading style and preferences. Commonly used time frames are 20, 30, or 50 periods. Experiment with different time frames to find the one that works best for you.
  4. Calculate the DPO: Subtract the moving average (MA) of the chosen time frame from the price of the security from a specified number of periods ago. The formula for DPO is as follows: DPO = Price - N-period MA, where N is the chosen time frame.
  5. Analyze the DPO values: Once you have calculated the DPO, observe the values it generates. Look for patterns or crossovers that align with your predefined trading rules. For example, you may consider a bullish signal if the DPO crosses above zero, indicating a potential buying opportunity.
  6. Set up triggers: Based on your analysis, set up specific triggers for entering or exiting trades. These triggers could be simple or complex, incorporating multiple indicators or conditions in addition to the DPO signal.
  7. Test and optimize: Backtest your trading strategy using historical price data to evaluate its effectiveness. Make adjustments to your rules and triggers if necessary. Optimize the strategy by testing different parameter settings and assessing their performance.
  8. Implement risk management: Integrate risk management practices into your strategy, such as placing stop-loss orders to limit potential losses and adjusting position sizing based on your risk tolerance.
  9. Monitor and adapt: Continuously monitor the performance of your trading strategy and make necessary adjustments as market conditions change. No strategy is guaranteed to be successful indefinitely, so it's essential to stay adaptable.

Remember, building a trading strategy using the Detrended Price Oscillator (DPO) requires thorough testing and practice. It's crucial to be patient and disciplined in your approach.
