This 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...
Ehlers Deviation-Scaled Moving Average indicator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:8: The Deviation-Scaled Moving Average).
Work 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.
This 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
// 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
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."
Ehlers Stochastic Cyber Cycle indicator script.
This indicator was originally developed by John F. Ehlers (see his book `Cybernetic Analysis for Stocks and Futures`, Chapter 8: `Stochasticization and Fisherization of Indicators`).
Ehlers Cyber Cycle indicator script.
This indicator was originally developed by John F. Ehlers (see his book `Cybernetic Analysis for Stocks and Futures`, Chapter 4: `Trading the Cycle`).
Finite Impulse Response (FIR) Filter indicator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 20:7 (26-31): Zero-Lag Data Smoothers).
NOTE: Ehlers' favorite FIR filter had 1, 2, 3, 3, 2, 1, 0 coefficients.
Recursive Median Filter indicator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:03 (8–11): Recursive Median Filters).
Recursive Median Oscillator indicator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:03 (8–11): Recursive Median Filters).
Rocket RSI indicator script.
This indicator was originally developed by John Ehlers (Stocks & Commodities V.36:6, RocketRSI - A Solid Propellant For Your Rocket Science Trading).
Infinite Impulse Response (IIR) Filter indicator script.
This indicator was originally developed by John Ehlers (Stocks & Commodities V. 20:7 (26-31): Zero-Lag Data Smoothers).
Adaptive Laguerre Filter indicator script.
The Adaptive Laguerre Filter was originally developed and described by John Ehlers in his paper `Time Warp – Without Space Travel`.
Thanks to @apozdnyakov for the sorting solution.
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...
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...
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.
