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.
Let me know if you would like to see me publish other scripts or if you want something custom done!

Ehlers Correlation Angle IndicatorThe 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.

Correlation Cycle, CorrelationAngle, Market State - John EhlersHot off the press, I present this "Correlation Cycle, CorrelationAngle, and Market State" multicator employing PSv4.0, originally formulated by Dr. John Ehlers for TASC - June 2020 Traders Tips. Basically it's an all-in-one combination of three Ehlers' indicators. This power packed triplet indicator, being less than a 100 line implementation at initial release, is a heavily modified version of the original indicator using novel techniques that surpass John Ehlers' original intended design.
This is also a profound script in numerous ways. First of all, these three indicators are directly from the illustrious mastermind himself Dr. John Ehlers. Secondarily, this is my "50th" script published on TV, which makes it even more significant. I'm especially proud of this script to "degrees" of imagination I once didn't know was theoretically possible in code. My intellect has once again been mathemagically unlocked pondering new innovations with this code revelation. Thirdly, this PSv4.0 script shows the empowering beauty and elegance of hacking the stock markets with TV's ultra utilitarian Pine Editor(PE) in a common browser! Some of you may be wondering if I worked on this for days... nope! This only took a few hours, followed by writing this description for another hour plus.
I have created many of Ehlers' indicators in PE, a few of which I have published in my profile, but I wanted to show how programming with Pine Script can be an artistic form of craftsmanship and poetry. None of this would be possible without the ingeniously minded Tradingview staff revolutionizing algorithmic trading at it's finest. If you should ever encounter them by chance, ponder humbly thanking these computing wizards for their diligence and dedication. They are providing, and shall award to us members, some of the most fascinating conceptualized tech imaginable in the coming future. I can assure you, much, much more is yet to be unveiled for us TV members/enthusiasts. Thank you TV and all you offer to this community.
As always, I have included advanced Pine programming techniques that conform to proper "Pine Etiquette" by example. There are so many Pine mastery techniques included, I don't have an abundance of time to elaborate on all of them. For those of you are code savvy, you may have notice I only used one "for" loop for increased server efficiency, instead of the two "for" loops in the original formulation. For those of you who are newcomers to Pine Script, this code release may also help you comprehend the immense "Power of Pine" by employing advanced programming techniques while exhibiting code utilization in a most effective manner. This is commonly what my dense intricate code looks like behind the veil. If you are wondering why there is hardly any notes, that's because the notation is primarily in the variable naming.
Features List Includes:
Dark Background - Easily disabled in indicator Settings->Style for "Light" charts or with Pine commenting
AND a few more... Why list them, when you have the source code!
The comments section below is solely just for commenting and other remarks, ideas, compliments, etc... regarding only this indicator, not others. When available time provides itself, I will consider your inquiries, thoughts, and concepts presented below in the comments section, should you have any questions or comments regarding this indicator. When my indicators achieve more prevalent use by TV members, I may implement more ideas when they present themselves as worthy additions. As always, "Like" it if you simply just like it with a proper thumbs up, and also return to my scripts list occasionally for additional postings. Have a profitable future everyone!
[LunaOwl] Center of Gravity作品: 艾勒斯重心點 (Center of Gravity, CG)
Center of Gravity was developed by John Ehlers in 2002. The main purpose of the Center of Gravity indicator is to find possible reversal points as early as possible. Indicator has two series, the first is the CoG series, and the second is the signal line calculated by the five-period smoothed moving average. Cross representative indication of the direction. I coded this indicator according to the description of MT4, a little work.
重心點（Center of Gravity）是由約翰．艾勒斯在2002年開發的，這個指標的主要用途是儘早發現可能的反轉點。它有兩個部份，一個是重心點指標線，另一個是經過五期平滑移動平均線平滑過的信號線，它們的交叉結果代表方向。我按照MT4的說明編寫了這個小作品。
powerful moving average crossoverThis script is a simplified version of John Ehlers's adaption of Dr. Kalman's optimum estimator as applied to price action (More can be found on this here: www.dimensionetrading.com). Here I have adapted two of these optimum estimators to work together to provide crossover signals. The user can choose the input of this filter in the 'input source'. The 'Ratio of Uncertainties' controls how adaptive the moving averages are, increasing this number will increase adaptivity and vice versa for decreasing. The 'Kalman Gain' allows the user to choose how much error to let into the calculation. The smaller this number is the quicker the moving average will approach price action.
In practice this indicator is much smoother than most other moving averages and has significantly less whiplash while still getting very early entries. If anyone wants to adapt this script for their own uses please feel free. Message me what you make with it, I am very curious what this can do when in the right hands!
Happy trading!
Ehlers Discrete Fourier TransformThe Discrete Fourier Transform Indicator was written by John Ehlers and more details can be found at www.mesasoftware.com
I have color coded everything as follows: blue line is the dominant cycle, orange line is the power converted to decibels, and I have marked the other line as red if you should sell or green if you should buy

Correlation Trend Indicator - Dr. John EhlersHot off the press, I present this "Correlation Trend Indicator" employing PSv4.0, originally formulated by Dr . John Ehlers for TASC - May 2020 Traders Tips. John Ehlers might describe it's characteristics as being a mean reverting trend identification oscillator range bound to +/-1.0 irregardless of any timeframe or asset. I could have finessed this indicator with all kinds of bells and whistles, but I wanted to keep it simple and handy enough for novice Pine programmers or Tradingview newcomers to use. This algorithm, in a slightly modified form, is actually a small portion of the base code for John Ehlers' highly complex Autocorrelation Periodogram and his Convolution SwamiChart.
Some members may have notice that I published a very similar script last month. That is correct. It's sole intention was completely different, having more diverse versatility and complexity, but with slightly reduced computational performance. While they seem eerily similar, they are genetically different. This function only has only one required "series" parameter and the correlation is calculated using the period, not bar_index. Correlating with bar_index or period yields identical results either way. Bottom line, this indicator is elegantly simplistic, yet highly utilitarian and easy to use.

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.
Extras
As usual when porting indicators to the library here on tradingview, I like to add some extra flare!
💠Customizable Overbought and Oversold Zones for Alert Creation
💠Bar coloration based on trade state for easy visual at a glance chart checking

Enjoy!
👍 We hope you enjoyed this indicator and find it useful! We post free crypto analysis, strategies and indicators regularly. This is our 81st script on Tradingview!
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.

Laguerre RSILaguerre RSI is based on John EHLERS' Laguerre Filter to avoid the noise of RSI.
Change alpha coefficient to increase/decrease lag and smoothness.
Buy when Laguerre RSI crosses upwards above 20.
Sell when Laguerre RSI crosses down below 80.
While indicator runs flat above 80 level, it means that an uptrend is strong.
While indicator runs flat below 20 level, it means that a downtrend is strong.

Ehler's Ideal RSI with EMAThis is a modification of the 'Ehlers Ideal RSI' script to include an EMA of the RSI, which acts as a follower!
The idea was a user suggestion and if you would like your suggestion made into an indicator, check the FAQ!
If you've never encountered the iRSI before, then you're in for a treat. This RSI will calculate the best period to use by itself.
The theory behind this math is called "Instantaneous Frequency Measurement" and is a big component of making terrible indicators (see RSI, Stoch, ADX) into usable ones!
No longer will you have to swap between different periods for different Stocks, Pairs, or Cryptos.
Compare it to the normal RSI and you'll see the underlying calculation is the same, but the period changes automatically.
The EMA provides an earlier indicator of breakouts.
You don't need to wait for this RSI to become "overbought" or "oversold" by crossing the typical 80/20 levels.
Simply observing when the RSI crosses the EMA line can act as confirmation for your other indicators much faster than typical momentum-based indicators.
FAQ
Why is your script Protected?
Users like to take my open-source code and charge to use it without my permission.
How do I use this to trade?
Add it to your chart and see what stacks up with your current setup. I trade Forex, so what looks bad on my charts might look golden on yours.
How long have you been doing this?
I've been coding for about 8 years and actively trading for 2 years. My degree is in Robotics Engineering and I became obsessed with investing at 22.
How do you trade?
Hurst + SNR + MESA MAMA + ATR + LSTM + Pure Grid. You can't completely code this setup using Pinescript, but if you learn C++ or Python you're there!
Are your returns good?
I average 0.68% every weekday or 22.65% monthly, using the method above.
Can you build my indicator or strategy?
Absolutely! If it hasn't been done before and it improves our community, then consider it done.
But can you build an indicator or strategy for me ?
Citing the house rules, I cannot solicit for any purpose. So saying "PM me" would be a grievous violation of said rules, obviously.

Aqua/Purple : Trend
[e2] Reflex & TrendflexNew Indicator from John F. Ehlers issued in the February 2020 Technical Analysis of Stocks and Commodities article "Reflex: A New Zero-Lag Indicator"
This indicator includes both studies described in the article and intend to significantly reduce the lag of the signal compared to other oscillators.
Reflex for the cycle component and is more sensitive to major reversals, Trendflex for the trend component.
Pivot Max range as the borders for top and bottom reading of the indicators (the script will plot separate borders for both components) and divergences were added.
Divergence function is the interpretation of built-in divergence script, optimized the code and added option to show real-time divs (without offset), all credits to ...)
daily*tip: I must say that very quickly I began to realize how fragmented and imperfectly modern economic knowledge is and how little can be taken from fundamental science in terms of practical recipes. (c) Andrey Movchans.

Voss Strategy (Filter + Trend Indicator) [Bitduke]Created strategy based on Voss Predictive Filter, implemented by TradingView user e2e4mfck.
Voss Predictive Filter
This is a relatively new filter from John F. Ehlers’ article, “A Peek Into The Future .” Ehlers describes the calculation of a new filter that could help signal cyclical turning points in markets.
But filter has a negative group delay and while an indicator based on it cannot actually see into the future, it may provide the trader with signals in advance of other indicators.
In mentioned article he tested filter on SPY and at one point in time "it went into a trend mode in January 2019, and the cycle signal failed miserably, signaling a short position during the runup. <...> The only way to minimize the impact of this condition is to employ an additional trend detector."
Thus I've added another Ehlers' based trend based indicator Instantaneous Trendline (thanks to LazyBear for implementation) to minimize the impact of the trend mode and got a good results on XBTUSD pair 4h.
Backtest :
> Range: 2016 - 2020
> XBTUSD
> 4h
> ~20% drawdown
> Sharpe (0.361, not too impressive)
I think it can be improved with Risk Management system and experimenting with various trend following indicators.
Market ModeThe Market Mode indicator seeks to identify trends and rebounds by identifying “phases” according to the principles of John Ehlers.
- When the oscillator passes above the top line, the market is in an uptrend.
- When the oscillator goes below the bottom line, the market is in a downtrend.
- Between these two levels, the market is calmer and could rebound in the direction of the initial trend and / or phase of trend change.
Strategy based on Ehlers Smoothed Adaptive Momentum [LazyBear]Strategy based on Ehlers Smoothed Adaptive Momentum (ESAM) indicator by LazyBear, slightly improved.
Indicator itself was developed and described by John F. Ehlers in his book "Cybernetic Analysis for Stocks and Futures" (2004, Chapter 12: Adapting to the Trend).
Backtesting: XBTUSD (Bitmex): 2h, 3h, 4h
Zentrading Trend Indicator v3.1This is a script for beta testing only.
Based on ichimoku, but with slightly different behaviour, with many added features such as : trend detection, momentum detection, multiple time frame support/resistance levels, exhaustion/reversal signals.
Used in conjunction with the other ZT indicators (ZT momentum, ZT CyclePhase, and ZT Volumebars) the strategy provides very distinct setups to trade for reversals, breakouts and pullbacks.
ZenTrading CyclePhaseThis is a script for beta testing only.
Used to mainly to spot (short-term) divergences
Roofing Filter [DW]This is an experimental study built on the concept of using roofing filters on price data proposed by John Ehlers.
Roofing filters are a type of bandpass filter conventionally used in HF radio receivers in the first IF stage to limit the frequency spectrum passed on to later stages in the receiver.
The goal in applying roofing filters to a price signal is to simultaneously attenuate high frequency noise and low frequency distortion to pass an oscillating signal with a nearly zero mean for analysis and/or further calculation.
In this study, there are three filter types to choose from:
-> Ehlers Roofing Filter, which passes data through a 2 pole high pass filter, then through a Super Smoother filter.
-> Gaussian Roofing Filter, which passes data through a 2 pole Gaussian high pass filter, then through a 2 pole Gaussian low pass filter.
-> Butterworth Roofing Filter, which passes data through a 2 pole Butterworth high pass filter, then through a 2 pole Butterworth low pass filter.
Each filter type has different amplitude and delay characteristics, so play around with each type and see which response suits your needs best.
There is an option to normalize the scale of the output as well. The normalization process in this script is computed by comparing positive and negative outputs to the filter's moving RMS value.
The resulting oscillator can be fed through numerous conventional indicators including Stochastic Oscillator, RSI, CCI, etc. to generate smoother, less distorted indicators for a clearer view of turning points.
Alternatively, it can also act as an indicator itself, as implied by the corresponding color scheme included in the script.
Although roofing filters are not conventionally used in the analysis of market data, applying such spectral analysis techniques may prove to be quite useful for the design of more efficient indicators and more reliable predictions.
Low Pass Channel [DW]This is an experimental study designed to attenuate higher frequency oscillations in price and volatility with minimal lag.
In this study, a single pole low pass filter is used. The low pass filter's cutoff period is determined either by a fixed user input, or by using an Instantaneous Frequency Measurement (IFM) algorithm.
Most radar warning, electronic countermeasures, and electronic intelligence systems employ IFM to identify threats, map the electronic battlefield, and implement deceptive countermeasures.
The IFM technique used for this study was devised by John Ehlers. It calculates In Phase and Quadrature (IQ) components using the Hilbert Transform and uses them to determine the dominant price cycle.
To generate the channel, the same filter approach is applied to true range then added to and subtracted from the price filter.
Custom bar colors are included for simple wave and trend indication.
Ehlers Super Passband FilterAs someone hidden my old script that is just what one guy copied from a book from John Ehlers. I rewrite what i read in the book.
I also found this. So i rewrite this to the guys that was using it. If it hiddes again i will just keep it to myself and downgrade my plan in this TV

BandPass EOS - 1hThis is a strategy i made for EOS
Opens a long position if the PB line (the red line in the oscillator) crossover the low of the band, the zero line or the top of the band.
If the PB line makes a crossunder in the top of the band, the zero line or the bottom of the band it closes the long position and immediately opens a short position.
Also, the PB value must be higher than 5 candles before if it is a long position and PB must be lower than 5 candles before to open a short position
I got the BandPass Script from www.tradingview.com and made some changes in the configs to adapt the strategy.
If someone has any doubt i can answer below
