Detrended Price Oscillator: Full guide for Day Traders

DPO is the best solution if you want to remove the noise of the price movements

Day trading is one of the most interesting and unique things you can do. It is interesting because of everything that happens in the market every day. It is unique because of how traders from around the world make money.

As we have written before, there are those who traders who believe in fundamental analysis. There are others who believe in technical analysis.

The technical analysis field is so wide and there are hundreds of indicators you can use. In this article, we will look at the Detrended Price Oscillator (DPO).

This is an indicator that many traders don’t know because it is not found as a default in some of the popular charting software.

What is the Detrended Price Oscillator?

The term detrended is derived from the term detrend. It is the opposite of using a trending.

Detrending is a concept that is used because some cycle behaviour is usually dependent on the direction of the next cycle. The reason for detrending is to remove the noise that is brought about by price movements.

The process of detrending is relatively simple: You simply divide the present price of an asset by the moving average of the price.

The Detrended Price Oscillator is calculated using the formula below:

Price (x/2 + 1)

where x is the number of periods that are used.

When the Detrended Price Oscillator is applied on a chart, it usually appears as a line that moves up and down.

It usually ranges between -0.05 and +0.05.

How to Use the Detrended Price Oscillator

As we have written before, most traders use oscillators to identify the overbought and oversold levels. A level is said to be overbought when the indicator moves so much higher.

In the case of the Detrended Price Oscillator, the overbought level can be said to be above 0.05. It is usually said to be oversold when it moved so much lower.

However, as we will explain, there are several ways of using the Detrended pattern.

Using the DPO’s Zero Line

One of the most effective ways of using the DPO indicator is to use the zero line. This is the line that appears in the middle.

The idea is that if the DPO line is moving from below the line and rising, it is an indication to buy. You should hold the trade so long as the DPO line is above the zero line.

As the price moves up, the DPO will fluctuate but you should not focus on these fluctuations. Instead, you should focus on the line when it crosses the zero line.

Similarly, if the DPO line moves lower and remains below zero, it is usually said to be a sell signal. A good example of this is shown on the Google chart shown below.

Using the Detrended Price Oscillator with Moving Averages

Another option of using the DPO is to use it together with moving averages.

The goal of this approach is to combine a trend indicator and one that is removing the trend. The approach we prefer is where the DPO is combined with a double exponential moving average.

We prefer using the EMA because it tends to be more accurate than the SMA. This is because it usually places an emphasis on the last closing price.

In the example below, We used a 21-day DPO and combined it with a 21-day and 10-day EMA.

The goal of doing this is relatively simple. We want to use the double EMA to identify when a new trend is about to form. This is known as a crossover.

If it points to a reversal, We look at the DPO to confirm the trend. We also use a combination of these indicators to confirm an ongoing trend.

Final Thoughts

The Detrended Price Oscillator (DPO) is not an indicator that many people know about. However, we have been using it for a while and we believe it is one of the most accurate indicators to use.

As a trader, we recommend that you first read more about it. We recommend that you use a book called; Technical Analysis: The Complete Resource for Financial Market Technician. It is written by Charles Kirkpatrick and Julie Dahlquest, and It is an excellent resource.

Also, We recommend that you practice the indicator, using it standalone or as a combination of other indicators. We suggest that you use it with the moving averages and the Average Directional Movement Index.
