Price curves consist of much noise and little signal. For separating the latter from the former, John Ehlers proposed in the Stocks&Commodities May 2021 issue an unusual approach: Treat the price curve like a radio wave. Apply AM and FM demodulating technology for separating trade signals from the underlying noise.

Background
John F. Ehlers introuced Dominant Cycle and Spectrogram Indicator in Mar, 2008.
Function
In "Measuring Cycle Periods" in Mar, 2008, John Ehlers presented a very interesting technique of measuring dominant market cycle periods by means of multiple bandpass filtering. By utilizing an approach similar to audio equalizers, the signal (here, the...
The Instantaneous Trendline was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 24) and this is an updated version of his original Instantaneous Trendline that works much better in my opinion. Buy when the indicator line turns green and sell when it turns red.
Let me know what other scripts you would like to see me publish or if you want...
The Triangle Moving Average is the last of custom scripts converting Ehlers Window Indicators to Moving Averages. As you can see this is actually very similar to the Hamming Moving Average and the Hann Moving Average so I would recommend to test this one out with different settings and see what works best for you. As far as the formula calculation, it is a...
The Correlation Angle Indicator was created by John Ehlers (Stocks & Commodities V. 38:06 (8–15)) and this is technically three indicators in one so I'm splitting each one to a separate script. This particular indicator was designed for trend termination and simply buy when it is green and sell when it turns red.
Let me know if you would like to see me publish...

The Leading Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 235) and as the name implies, this is a leading indicator that provides super early signals. Feel free to change the alpha values to adjust to your needs. Buy when the indicator line is green and sell when it is red.
Let me know if there are other scripts you would...
The NonLinear Filter was created by John Ehlers and this one of his more unknown filters that work very well as a trendline and moving average. This is one of my favorites along with the instantenous trendlines that he created. Buy when the line turns green and sell when it turns red.
Let me know if there are any other indicators you would like to see me publish...

John F. Ehlers introuced Fisherized Deviation Scaled Oscillator in Oct, 2018.
Function
In “Probability—Probably A Good Thing To Know,” John Ehlers introduces a procedure for measuring an indicator’s probability distribution to determine if it can be used as part of a reversion-to-the-mean trading strategy. Dr. Ehlers demonstrates this...

John F. Ehlers introuced adding the Fisher Transform to the Adaptive RSI in his "Cycle Analytics for Traders" chapter 15 on 2013.
Function
The purpose of the Fisher transform is to take any indicator having a nominally zero mean and bounded between the limits of −1 to +1 and convert the amplitude so that the transformed indicator has an...

John F. Ehlers introuced Leading Indicator in his "Cybernetic Analysis for Stocks and Futures" chapter 16 on 2004.
Function
The leading characteristic is present in the net filte.As predicted, the lead is one bar at very low frequencies. That is, the trend indication will lead by one bar. However, the net filter has a lag of approximately...
The Even Better Sinewave Indicator was created by John Ehlers (Cycle Analytics For Traders pgs 161-162) and this indicator works well when the stock is in a trend mode. It will let you know how long to stay with a trade and it works best with a trend confirmation but it can also work on it's own fairly well. Buy when the indicator line is green and sell when it is...
The Mesa Spectrum Dominant Cycle was created by John Ehlers and this is the foundation for many indicators he created that would later follow. This is his updated version of his original Mesa algorithm and I do not recommend this indicator as a stand alone for trading. This is more of an informational indicator that will tell you the current dominant cycle period...
The Sinewave Indicator was created by John Ehlers (Rocket Science For Traders pgs 97-99) and this is a few indicators in one. Simply put it is a leading indicator which you don't see too many of those these days. If the blue line crosses over the red line then within the next few bars the price will start an uptrend and if the blue line crosses below the red line...
The Spearman Rank Indicator was created by John Ehlers (Stocks and Commodities July 2020 pg 6) and this works well as a trend confirmation indicator. This is obviously his take on the Spearman Ranking Correlation and make sure to let me know what you think! Buy when the line turns green and sell when it turns red.
Let me know if there are any other indicators you...
The Sinewave Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 154-155) and this is an updated version of his original Sinewave Indicator which in my opinion seems to be more reactive to changes. Buy when the blue line crosses over the red line and sell when the blue line crosses under the red line. Also keep in mind that this...
The Super PassBand Filter was created by John Ehlers (Stocks & Commodities V. 34:07 (10–13)) and this is a pretty useful indicator to let you know how volatile the market is right now. This is useful for scalpers because this lets you avoid the choppy markets (usually when the rms is 1.50 or less but feel free to choose your own level) and gives you good entry and...

Background
John F. Ehlers introuced Super Passband Filter in Jul, 2016.
Function
In “The Super Passband Filter” in Jul, 2016, John Ehlers addressed the problem of frequencies in indicators that are too low or too high. The common practice to refine frequency is to enable smart filters. However, good filters take lots of computational power. So Ehlers...
