Intro This script measures the Signal to Noise ratio of a security and plots it in deciBels scale! Usage Ideally, you would want the ratio to be above 10 dB, meaning the Signal strength is 10x the noise strength. As a baseline, you should not rely on indicators that use any kind of moving average if the SNR is below 6 dB - meaning Signal strength is only 4x...
I compiled all of Ehlers' IFM methods into one script - all written as functional blocks so you can simply add them to your own scripts. Bonus! I also dropped in the Super Smoother, which is a much more efficient and low lag averaging method. I used it to clean the data before feeding it into other indicators.
The last of Ehlers Instantaneous Frequency Measurement methods. This is a more robust version of this script. I wrote it as a function, so you can simply copy and paste it into any script to add an adaptive period setting capability. Cheers, DasanC
A user has asked for the Study/Indicator version of this Strategy . If you encounter the error "loop....>100ms" simply toggle the eye icon to hide and unhide the indicator The following is simply quoted from my previous post for your convenience: (obviously there won't be risk, Stop Loss, or Take profit parameters!) OPERATING PRINCIPLE The strategy is...
This is my most successful strategy to date! Please enjoy and join the Open Source movement by sharing your code and ideas online! OPERATING PRINCIPLE The strategy is based on Ehlers idea that any indicator can be turned into a signal-producing trade system through smoothing and other filtering processes. In fact, I'm using his Zero Lag EMA (ZLEMA) as a baseline...
Yet another method for determining the cycle of a market: this time, you have access to the two fastest and most accurate methods as well as the option to average these methods together. The controls are pretty straight forward: Source lets you select the price data to perform calculations on (close, open, etc..) Max Period is simply the cap for the algorithm...
This is my latest bandpass filter - used to determine if a security is in a trend or cycle. Now with an adaptive period setting! I use Ehlers in-phase & quadrature dominant cycle measurement (IQ IFM) method to set the period dynamically. This method favors longer periods which tend to produce smoother, albeit laggier bandpass oscillator plots. From my quick tests,...
Behold! A strategy that makes use of Ehlers research into the field of signal processing and wins so consistently, on multiple time frames AND on multiple currency pairs. The Adaptive Zero Lag EMA (AZLEMA) is based on an informative report by Ehlers and Ric . I've modified it by using Cosine IFM, a method by Ehlers on determining the dominant cycle period without...
This indicator provides a continuous measurement of a securities' dominant cycle period, based on Ehlers ever-impressive reports and analysis tools. This method uses in-phase and quadrature analysis, making use of the imaginary domain. This method is prone to favor longer periods and can allow noise to greatly affect the end result. >What does that even...
This indicator provides a continuous measurement of a securities' dominant cycle period, based on Ehlers ever-impressive reports and analysis tools. >What does that even mean? Essentially, you get a real-time (low lag) plot of the cycle period in bars. If the COS IFM reads "16" then you can expect the distance between swing highs and swing lows to be approx. 16...
MESA Adaptive Moving Average aka: Mother of Adaptive Moving Averages: The MESA Adaptive Moving Average ( MAMA ) adapts to price movement in an entirely new and unique way. The adapation is based on the rate change of phase as measured by the Hilbert Transform Discriminator I have previously described.1 The advantage of this method of adaptation is that it...
This indicator was described by John F. Ehlers in his book "Rocket Science for Traders" (2001, Chapter 18: Ehlers Filters).
Ehlers Smoothed Adaptive Momentum script. This indicator was developed and described by John F. Ehlers in his book "Cybernetic Analysis for Stocks and Futures" (2004, Chapter 12: Adapting to the Trend).
Ehlers Instantaneous Trendline script. This indicator was described by John F. Ehlers in his book "Rocket Science for Traders" (2001, Chapter 10: The Instantaneous Trendline).
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).
Gaussian Filter script. This indicator was described by John F. Ehlers in his book "Rocket Science for Traders" (2001, Chapter 15: Infinite Impulse Response Filters).
This is a predictive indicator that looks for explosions in momentum of the cycles in price and large shifts in Momentum (Fisher turns the Bimodal PDF into Guassian like) as statistically unlikely events, showing points to exit or reverse positions. You can adjust the lowpass frequency cuttoff (Aka what cycles you want to remove from the calculations through the...
This is the Adaptive Ehlers Filter. I had to unroll the for loops and array because TV is missing crucial data structures and data conversions (Arrays and series to integer conversion for values). I'm in the process of releasing some scripts. This is a very old script I had. This contains volatility ranges and can be used as trading signals. You can also see...
