Guide to Detrended Price Oscillator (DPO) Are Calculated?

11 minutes read

The Detrended Price Oscillator (DPO) is a technical indicator used to analyze price movements and identify trends. It indicates the deviation of the current price from a historical moving average, helping to understand market cycles and potential reversal points.

To calculate the DPO, first, a simple moving average (SMA) is calculated for a specified period in the past, usually referred to as the "lookback period." This SMA is centered at the midpoint of this lookback period, rather than being anchored at the current price.

Next, the DPO is calculated by subtracting the value of the centered SMA from the price at the corresponding time period. This eliminates the underlying trend and focuses solely on the short-term price deviations from the longer-term average.

The formula for calculating DPO is as follows:

DPO = Price - SMA


  • Price represents the closing price of the asset for a particular time period.
  • SMA is the simple moving average calculated for the specified lookback period.

The resulting DPO values can be positive or negative, indicating overbought or oversold conditions respectively. Traders and analysts use DPO’s zero line (the x-axis) as a significant reference point, looking for buy signals when the indicator crosses above the zero line and sell signals when it falls below it.

DPO is particularly useful for identifying price cycles and timing entry or exit points in the market. By removing the trend component from the price data, it helps traders focus on shorter-term price movements and potential reversals. However, like any technical indicator, the DPO should be used in conjunction with other analysis techniques for more accurate predictions.

How to adjust the DPO period to suit different trading strategies?

Adjusting the Detrended Price Oscillator (DPO) period to suit different trading strategies involves considering various factors, including the timeframe of the strategy, the market conditions, and the desired sensitivity to price movements. Here are some steps to adjust the DPO period:

  1. Determine the timeframe: Consider the duration of your trading strategy. If you are a day trader, you may prefer a shorter DPO period like 10-20 days. For longer-term investing or swing trading, a longer DPO period of 20-50 days may be appropriate.
  2. Assess market volatility: Volatile markets may require a shorter DPO period to capture more frequent price cycles. Conversely, in less volatile markets, a longer DPO period is needed to filter out noise and identify meaningful price movements.
  3. Experiment with different periods: Test various DPO period settings by applying them to historical price charts or using backtesting tools. Observe how different periods affect the signals generated and analyze their suitability for your trading style.
  4. Consider other technical indicators: DPO is most effective when used in combination with other indicators. Review complementary indicators such as moving averages, oscillators, or trendlines to fine-tune the DPO period and validate signals.
  5. Adapt to changing market conditions: Keep in mind that market dynamics change over time. Periodically reassess and adjust the DPO period to adapt to current market conditions and optimize the indicator's effectiveness.
  6. Consider risk tolerance: Different trading strategies have varying risk tolerances. If you prefer a more conservative approach, choose a longer DPO period to avoid false signals. Conversely, a shorter period can generate more aggressive signals, but with an increased risk of false positives.

Remember, adjusting the DPO period should be based on your trading objectives, risk tolerance, and market conditions. Continuous monitoring and evaluation of the indicator's performance are essential to fine-tune its parameters for optimal results.

How can DPO be used for identifying potential entry and exit points in a trade?

DPO (Detrended Price Oscillator) can be used to identify potential entry and exit points in a trade by following these steps:

  1. Calculate the Detrended Price: Subtract the simple moving average (SMA) from the current price. This will remove the trend component from the price.
  2. Analyze the DPO Line: Plot the resulting Detrended Price values on a chart. The DPO line will oscillate above and below the zero line.
  3. Look for Reversal Points: Identify points where the DPO line crosses above or below the zero line. These crossings can indicate potential reversal points in the price trend.
  4. Seek Confirmation: Confirm the potential reversal points by looking for other technical indicators, such as support/resistance levels, trendlines, or other oscillators.
  5. Consider Entry and Exit Points: Based on the confirmed reversal points, determine the entry and exit points for your trades. For example, if the DPO line crosses above the zero line, it could be a signal to enter a long position. Conversely, if the DPO line crosses below the zero line, it might indicate a potential exit or a short position.
  6. Set Stop Loss and Take Profit Levels: Use appropriate risk management techniques by setting stop loss levels to limit potential losses and take profit levels to secure profits.
  7. Monitor and Adjust: Continuously monitor the DPO and other relevant indicators to adapt your trading strategy as the market conditions change.

How does DPO incorporate past price cycles into its calculation?

DPO (Detrended Price Oscillator) incorporates past price cycles into its calculation by removing the trend component from the price series. It calculates the difference between a specified past price and the average price over a certain period.

Here is the step-by-step process to calculate DPO and incorporate past price cycles:

  1. Choose a specific past price for which you want to determine its deviation from the average price.
  2. Determine the desired period for the average price calculation (e.g., 20-day moving average).
  3. Calculate the average price over the desired period.
  4. Subtract the average price from the chosen past price to obtain the detrended price.
  5. Plot the detrended price on a chart.
  6. Repeat steps 1-5 for each day or period in the series.
  7. Connect the detrended prices to create the DPO line.

By subtracting the average price from a chosen past price, DPO effectively eliminates the trend component from the price series, allowing traders to focus on shorter-term deviations and capturing past price cycles. The resulting DPO line represents these cycle deviations and enables trend analysis and identification of potential turning points.

How does the Detrended Price Oscillator help in identifying trend reversals?

The Detrended Price Oscillator (DPO) is a technical analysis tool that helps identify trend reversals by highlighting the short-term cycles or deviations from the long-term trend. Here's how it works:

  1. Detrending: The DPO calculates the difference between the price and the simple moving average (SMA) of a specified period. This detrended value represents the short-term price fluctuations.
  2. Identifying deviations: By detrending the price, the DPO focuses solely on the short-term cycles and removes the influence of the long-term trend. It helps in identifying periods where the price deviates significantly from the long-term trend.
  3. Reversal patterns: Trend reversals often occur after the price has deviated from the long-term trend and reached an extreme point. The DPO helps to identify these extremes, which can signal potential trend reversals.
  4. Zero line and crossover: The DPO is typically plotted with a zero line, which represents the long-term average price. When the detrended price crosses above the zero line, it suggests bullish momentum, indicating a potential trend reversal from bearish to bullish. Conversely, when it crosses below the zero line, it suggests bearish momentum and a potential trend reversal from bullish to bearish.
  5. Confirmation: The DPO is most effective when used in combination with other technical indicators, such as trendlines, support/resistance levels, or other oscillators. Traders may look for additional confirmation signals before making trading decisions based on DPO indications.

It's important to note that while the Detrended Price Oscillator can help identify potential trend reversals, it is not infallible, and false signals can occur. Therefore, thorough analysis and the use of multiple indicators are recommended to increase the accuracy of trend reversal identification.

What is the historical significance of the Detrended Price Oscillator?

The Detrended Price Oscillator (DPO) is a technical analysis indicator used to help identify cycles and trends in the price of a security. It measures the difference between a specific price point and a moving average of that price point, thus detrending the data. The historical significance of the DPO lies in its ability to provide traders and analysts with a clearer picture of the underlying price cycle and potential reversal points.

By removing the long-term trends from price data, the DPO focuses on short-term market movements, which can be useful in identifying overbought or oversold conditions. It can help traders spot potential turning points or periods of consolidation in a security's price, which is crucial for making informed trading decisions.

The DPO has been used by technical analysts for many years as a tool to analyze price patterns and predict potential market movements. Its historical significance lies in its effectiveness in aiding traders to identify turning points and trade within shorter-term cycles, aligning with various trading strategies and approaches.

Overall, the DPO's historical significance lies in its ability to provide a unique perspective on price data, allowing traders to better understand market cycles and make more informed trading decisions.

What are the primary applications of the Detrended Price Oscillator?

The primary applications of the Detrended Price Oscillator (DPO) include:

  1. Identifying cycles: The DPO is commonly used to identify cycles or trends in a financial instrument's price movement. By eliminating the overall trend, it focuses on shorter-term cycles or patterns, enabling traders to identify potential turning points or reversals in the market.
  2. Generating buy/sell signals: Traders often use the DPO to generate buy or sell signals. When the DPO crosses above zero, it can indicate a bullish signal, suggesting that the price is likely to rise. Conversely, when the DPO crosses below zero, it may indicate a bearish signal, suggesting that the price is likely to decline.
  3. Confirming trend strength: The DPO can be used as a confirmation tool for the strength of an existing trend. If the DPO is rising and remains positive during an uptrend, it suggests that the upward momentum is strong. Conversely, if the DPO is falling and remains negative during a downtrend, it indicates that the downward momentum is strong.
  4. Divergence analysis: Traders also use the DPO for divergence analysis, which involves comparing the highs or lows of the indicator with the corresponding highs or lows of the price. Divergences can provide insights into potential upcoming trend reversals.
  5. Overbought/oversold conditions: Similar to other oscillators, the DPO can also be used to identify overbought and oversold conditions. When the DPO reaches extreme levels, such as above a certain threshold, it may suggest that the price is overbought and due for a correction. Conversely, when it reaches extreme negative levels, it may indicate that the price is oversold and due for a potential bounce.

It's important to note that while the DPO can provide useful insights, it should be used in combination with other technical analysis tools and indicators for more accurate trading decisions.
