This is an experimental study that calculates filter values at user defined sample rates. This study is aimed to provide users with alternative functions for filtering price at custom sample rates. First, source data is resampled using the desired rate and cycle offset. The highest possible rate is 1 bar per sample (BPS). There are three resampling methods to...

Modified Ehlers Empirical Mode Decomposition indicator for swing trade based on Butterworth 2nd order IIR filter Description This script is inspired by John Ehlers' TECHNICAL PAPERS - Truncating Indicators and Empirical Mode Decomposition. But instead of detecting trend it applies to finding swing regions. Also here is suggested canonical DSP approach for...

This is an experimental study built on the concept of using roofing filters on price data proposed by John Ehlers. Roofing filters are a type of bandpass filter conventionally used in HF radio receivers in the first IF stage to limit the frequency spectrum passed on to later stages in the receiver. The goal in applying roofing filters to a price signal is to...

The 3 Pole Butterworth Filter was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 196-197) and this indicator is a moving average that also works well as a trendline. Buy when the indicator line turns green and sell when it turns red. Let me know if you would like me to publish other indicators or if you want something custom done!

Butterworth Filter script. This indicator was described by John F. Ehlers in his book "Rocket Science for Traders" (2001, Chapter 15: Infinite Impulse Response Filters).

The 2 Pole Butterworth Filter was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 192) and this is one of his many filters that cuts out the noise and follows the price very closely. I recommend combining a 2 pole and 3 pole system of the same type of filter. Buy when the indicator line is green and sell when it is red. Let me know if there...

Level: 2 Background John F. Ehlers introuced Three-Pole Butterworth Filter in his "Cybernetic Analysis for Stocks and Futures" chapter 13 on 2004. Function The transfer responses of Butterworth filters have polynomials in both the numerator and denominator. There is a polynomial in the numerator as well as the denominator. The significance of the polynomial...

The 3 Pole Butterworth Filter was created by John Ehlers (Cycle Analytics For Traders pg 32) and this is a nice filter that follows the price very closely. Buy when the indicator is green and sell when it turns red. This was a custom request so let me know if you would like me to publish any other scripts or if you want something custom done!

Level: 2 Background John F. Ehlers introuced Two Pole Butterworth Filter in his "Cybernetic Analysis for Stocks and Futures" chapter 13 on 2004. Function Dr. Ehlers translated analog Butterworth filters to their digital approximations. The transfer response is characterized by a single variable—the cutoff frequency. The cutoff frequency is that frequency...

The 2 Pole Butterworth Filter was created by John Ehlers (Cycle Analytics For Traders pg 32) and this is an updated version of his original 2 pole Butterworth Filter script that seems to follow the price even closer. Buy when the indicator line turns green and sell when it turns red. Let me know if there are other scripts you would like to see me publish or if...

It passes the Rate of Change data through a Butterworth filter which creates a smooth line that can allow for easier detection of slope changes in the data over various periods of times. The butterworth filter line and the rate of change are plotted together by default. The values for the lengths, for both the butterworth filter and the raw ROC data, can be...
