Ehlers
reverse EMA Osc - John EhlersThis an universal oscillator with features such as minimum lag and a single-input parameter that lets it highlight cycle, momentum, and trend components.
It is based on reverse impulse response filter technique applied to EMA.
Color style borrowed from Awesome Oscillator, between one can notice a better lag response with this indicator.
DFT - Dominant Cycle Period 8-50 bars - John EhlerThis is the translation of discret cosine tranform (DCT) usage by John Ehler for finding dominant cycle period (DC).
The price is first filtered to remove aliasing noise(bellow 8 bars) and trend informations(above 50 bars), then the power is computed.
The trick here is to use a normalisation against the maximum power in order to get a good frequency resolution.
Current limitation in tradingview does not allow to display all of the periods, still the DC period is plot after beeing computed based on the center of gravity algo.
The DC period can be used to tune all of the indicators based on the cycles of the markets. For instance one can use this (DC period)/2 as an input for RSI.
Hope you find this of some interrest.

CM_Ultimate_MA_MTF_V3 GUNBOTWork in progress... Added new MAs with variable smoothing... EhlersSuperSmoother, EhlersEmaSmoother, xema. Added additional alerts for gunbot or similar cryptobots. Couldn't find the original author of the new MAs, so if you are, drop me a line for credit.
Fisher Transform Money Flow IndexThis is an experimental indicator by applying Money Flow Index with Fisher Transform. i found MFI code and Fisher transform code from public library.
Use longer length to find divergence. Tune the length and samples according to your trading style and instrument
Fisher Transform SuperSmoothed MACD // This is a modification of Supersmoothed MACD (created by KIVANC using EHLERS' SUPER SMOOTHER FILTER) and sharpenned with Ehler fisher transform
//all lengths and parameters are completely configurable, tune the length according to your instrument
//give me what you think
Ehlers DSMA by Tim D.The Deviation-Scaled Moving Average from July 2018 TASC. "In “The Deviation-Scaled Moving Average” in this issue, author John Ehlers introduces a new adaptive moving average that has the ability to rapidly adapt to volatility in price movement. The author explains that due to its design, it has minimal lag yet is able to provide considerable smoothing."

Thanks to @apozdnyakov for the sorting solution.
Relative Vigor Index with Dominant Cycle Detection (RVI)Relative Vigor Index with Dominant Cycle Detection. As Ehler's mentioned, fixed length look back is inherently flawed when it is possible to extract a length from a dominant price cycle. may be less effective if signal to noise ratio is greater than 2, but that usually would not happen at >5m candles, and honestly shouldn't be looking at RV(igor)I when price is moving sideways.
Read just like an RVGI, but adjusted to the current time frame. To reduce noise, changing to heiken ashi will help with signals as well. Let me know if there are improvements!
Made for JD, the OG.
Gaussian Channel [DW]This study is an experiment utilizing the Ehlers Gaussian Filter technique combined with lag reduction techniques and true range to analyze trend activity.
Gaussian filters, as Ehlers explains it, are simply exponential moving averages applied multiple times.
First, beta and alpha are calculated based on the sampling period and number of poles specified. The maximum number of poles available in this script is 9.
Next, the data being analyzed is given a truncation option for reduced lag, which can be enabled with "Reduced Lag Mode".
Then the alpha and source values are used to calculate the filter and filtered true range of the dataset.
Filtered true range with a specified multiplier is then added to and subtracted from the filter, generating a channel.
Lastly, a one pole filter with a N pole alpha is averaged with the filter to generate a faster filter, which can be enabled with "Fast Response Mode".
Custom bar colors are included.
Note: Both the sampling period and number of poles directly affect how much lag the indicator has, and how smooth the output is.
Larger inputs will result in smoother outputs with increased lag, and smaller inputs will have noisier outputs with reduced lag.
For the best results, I recommend not setting the sampling period any lower than the number of poles + 1. Going lower truncates the equation.
Laguerre RSI (Self Adjusting Alpha with Fractals Energy)Laguerre RSI (Self Adjusting Alpha with Fractals Energy) indicator script. I adopted idea from www.prorealcode.com and
If you disable `Apply Fractals Energy` option, you will get the original Laguerre RSI.
The Perfect RSI (Ehler's Cycle RSI Modified with Discriminator)This is the RSI indicator that I use. It combines two concepts of John Ehler. It integrates the idea of Highpass filtering the Price data, along with the the idea of automatically determining the Dominant price cycle through a Homodyne Discriminator, and using half of a cycle length as the input for the RSI. Not only determines the most effective range for the RSI by setting it based on the cycle, but also makes the RSI PDF(Probability Distribution Function) adjustable as shown in John Ehler's papers. Still needs some tweaking on determining the best calculations for cycles, and whether or not to better filter the price data into the discriminator.
Works just like a normal RSI, but should have less false signals, and also has the option for super smoothing. Play around it and see if theres any new indications or signals that come from it ;)
Let me know if there's any concerns or additions!
