Ehlers Truncated BandPass Filter [CC]Hot off the presses! The Truncated BandPass Filter was created by John Ehlers (Stocks & Commodities July 2020) and this is a much more reactive version of his original bandpass filter. When the indicator rises above 0 then it is an uptrend and when it falls below 0 then it is in a downtrend. Buy when the indicator line is red and sell when it is green.

This will let you know when the stock is at a high volatility or not and when to buy or sell. If the indicator crosses over the dotted line then that means the stock is volatile and it is trading flat then it will be below the dotted line. Buy when the indicator line is green and sell when it is red.

Ehlers Decycler [CC]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.

Ehlers Hilbert Oscillator [CC]The Hilbert Oscillator was created by John Ehlers (Rocket Science For Traders pgs 90-91) and just like the sinewave indicator that I published yesterday, this is also a leading indicator. The big difference between this indicator and the sinewave is that this indicator works very well for determining major turning points in the stock before they happen. You will notice that when the blue line crosses over the red line that a few bars from that point, the stock will start an uptrend and the reverse is true. I have also included immediate buy and sell signals over the 0 line so buy when the line is green and sell when it is red

Ehlers Sinewave Indicator [CC]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 then in the next few bars it will start a downtrend. I have also included an immediate buy and sell signal on the 0 line which is green when you should buy and red when you should sell.

Ehlers Even Better Sinewave Indicator [CC]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 red.

Ehlers Fisher Stochastic Center Of Gravity [CC]The Fisher Stochastic Center Of Gravity Indicator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 95) and this is a combo cycle indicator mixed with a stochastic indicator. The idea is to capture the beginning of the cycle and ride it until the end. Buy when the indicator line is green and sell when it turns red.

Ehlers Fisher Transform Indicator [CC]The Fisher Transform Indicator was created by John Ehlers and the beauty of this indicator is that it provides sharp and clear turning points that are also very early. Buy when the indicator line is green and sell when it is red.

Ehlers Market State Indicator [CC]The Market State Indicator was created by John Ehlers (Stocks & Commodities V. 38:06 (8–15)) and this is technically part of three indicators in one so I'm splitting each one to a separate script. This particular indicator was designed for the market state which acts as a trend direction and tells you whether the trend is strong in either direction. Keep in mind that when the indicator rapidly switches then the market is choppy and when it is a steady line then it is a very strong trend. Essentially buy when the indicator line is green and sell when it is red.

Ehlers Spectrum Derived Filter Bank [CC]The Spectrum Derived Filter Bank was created by John Ehlers (Stocks & Commodities V. 26:3 (16-22)) and this is technically two indicators in one. This will let you know the current cycle period which is in blue and the other indicator will let you know if you should buy the stock or not. Buy when it is green and sell when it is red.

Ehlers Dominant Cycle Tuned Bypass Filter [CC]The Dominant Cycle Tuned Bypass Filter was created by John Ehlers (Stocks & Commodities V. 26:3 (16-22)) and this is a particularly unique indicator because this does a pretty good job at predicting the future stock movements. If the blue line crosses over the red then a few bars from now the stock price will most likely go up and if the blue line crosses below the red then a few bars from now the stock price should go down. Since this is such a unique indicator to use with entry and exit points, I don't have them color coded but try this out and let me know what you think.

Ehlers Swiss Army Knife Indicator [CC]The Swiss Army Knife Indicator was created by John Ehlers (Stocks & Commodities V. 24:1 (28-31, 50-53)) and it is 9 different filters in one big mega indicator! This is my first attempt at allowing you all to select different timeframes, to choose if you allow repainting or not, or by letting you choose which indicator you want to see on the chart. I know this may cause problems so feel free to send me a pm if you are stuck or if you have any questions!

Ehlers Correlation Cycle IndicatorThe Correlation Cycle Indicator was created by John Ehlers (Stocks & Commodities V. 38:06 (8–15)) and this is technically part of three indicators in one so I'm splitting each one to a separate script. This particular indicator was designed for trend direction and trend strength and simply buy when it is green and sell when it turns red. Also keep in mind that the higher the indicator is above the signal then the stronger the trend and when they are close together, conditions get choppy.

Ehlers Discrete Fourier TransformThe Discrete Fourier Transform Indicator was written by John Ehlers and more details can be found at www.mesasoftware.com

Ehlers Correlation Trend Indicator CTI by Cryptorhythms [CR]Ehlers Correlation Trend Indicator CTI by Cryptorhythms
📜Intro
In his article “Correlation As A Trend Indicator” in issue May 2020 of TASC, author John Ehlers introduces a new trend indicator that is based on the correlation between a security’s price history and the ideal trend: a straight line. He describes methods for using the indicator to not only identify the onset of new trends but to identify trend failures as well. He presents what looks like a simple and elegant idea for a trend-detection and mode-switching indicator.
📋Comments
Careful market selection may be the key to a correct application of the indicator. Even such barebone rules could shine with stocks like AAPL that tend to develop prolonged trends. But for others like CAT, which can keep oscillating in ranges for years, results will be much less impressive. They require a different approach. For example, you would want to buy when Correlation Trend falls significantly below zero and sell when it reaches positive values.
Therefore, it would be an interesting problem to research Correlation Trend’s ability to identify the switch to a cycle mode. That might help develop countertrend systems and
trade pullbacks. Another possible application might be to act as a system filter of change from trending mode to mean-reversion mode.

Phase CalculationPhase Calculation was authored by John F. Elders in the Stocks and Commodities Magazine 11/1996
This indicator will tell you if the stock is in a uptrend or downtrend. A phase number with a low number means it is in a uptrend and a phase number with a high number means it is in a downtrend.
