John F. Ehlers introuced Decycler in his book "Cycle Analytics for Traders", chapter 4. The decycler is designed to remove the influence of shorter cycle fluctuations, resulting in an output that closely resembles a one-pole low-pass filter. A standout feature of the decycler is its notably minimal lag. The most extended cycle elements experience a delay of...
Level: 2 Background John F. Ehlers introuced Decycler Oscillator in Sep, 2015. Function In “Decyclers” in Sep, 2015, John Ehlers described a method for constructing an oscillator that could help traders detect trend reversals with almost no lag, an oscillator that signals trend reversals with almost zero lag via digital signal processing techniques. A...
Level: 2 Background John F. Ehlers introuced Decycler Oscillator in his "Cycle Analytics for Traders" chapter 4 on 2004. Function A decycler oscillator is created by subtracting the output of a high-pass filter having a shorter cutoff period from the output of another high-pass filter having a longer cutoff period. This way, both elements have a zero in their...
Level: 2 Background John F. Ehlers introuced Decycler in his "Cycle Analytics for Traders" chapter 4 on 2004. Function The concept of a decycler is really pretty simple. The cyclic components are removed by the process of cancellation. If the high-pass filter output is subtracted from the input data, the residual only contains the low-frequency components....
The Decycler Oscillator was created by John Ehlers (Cycle Analytics For Traders pgs 43-44) and it is used to show transitions between uptrends and downtrends. If it rises above the 0 line then this means it has transitioned to an uptrend and it falls below the 0 line then it is in a downtrend. Buy if the indicator line is green and sell when it is red. This was a...
The Decycler was created by John Ehlers (Cycle Analytics For Traders pgs 40-41) and this is a moving average that has an extremely low lag even though it uses a fairly high length to calculate everything. This can also work well as a trendline. Buy when the indicator line is green and sell when it is red. Let me know if there are other scripts you would like to...
This indicator was originally developed by John F. Ehlers (Stocks & Commodities , V.33:10 (September, 2015): "Decyclers"). The idea is still the same as for the Simple Decycler. Mr. Ehlers suggested to virtually eliminate lag by getting rid of the very low-frequency components. So, he applied the high-pass filter to the simple decycler. Mr. Ehlers recommended to...
This indicator was originally developed by John F. Ehlers (Stocks & Commodities, V.33:10 (September, 2015): "Decyclers"). Mr. Ehlers suggested a way to improve trend identification using high-pass filters. The basic smoothers like SMA, low-pass filters, have considerable lag in their display. Mr. Ehlers applied the high-pass filter and subtracted the high-pass...
