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!

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.

📜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.

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.

[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 ...)

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.
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.

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.

MTF IQ IFM Moving AverageMTF ready adaptive MA using Ehler's IQ IFM ( In Phase - Quadrature Instantaneous Frequency Measurement ).
Ehler's formula is a method of quantitatively measuring the length of a market cycle. In this case it is used to calculate the "optimal" adaptive EMA.
Theoretically the length generated by Ehler's formula could be used in many indicators and it's been placed within it's own function so you should be able to simply copy/paste it. HOWEVER pine will not accept series variables for the length input used in built-in functions. You will have to manually code (or find) a version of your indicator that doesn't use the pine built in.
Options :
type : optionally add volume weighting
range : historical range used in IQ IFM
cycle length mult : method to create faster/slower MAs. eg 0.5 is half the length of a cycle and a faster EMA ie EMA10 vs EMA20
low sat fix : some cryptocurrencies with low satoshi values cause an issue with the calculation, if you get no/nonsensical lines, enable this. Shouldn't affect other instruments, but can be disabled just in case.
MTF options: run the calculation on an alternative timeframe

Center of Gravity Oscillator - Ehlers by KIVANC fr3762Center of Gravity OSCILLATOR by JOHN EHLERS
Converted the original code from his book "Cybernetic Analysis for Stocks and Futures"
This article describes a new oscillator that is unique because it is both smoothed
and has essentially zero lag. The smoothing enables clear identification of turning
points and the zero lag aspect enables action to be taken early in the move. This
oscillator is the serendipitous result of my research into adaptive filters. While the filters
have not yet produced the result I seek, this oscillator has substantial advantages over
conventional oscillators used in technical analysis . The “CG” in the name of the
oscillator stands for the Center of Gravity of the prices over the window of observation.
The Center of Gravity ( CG ) of a physical object is its balance point. For example,
if you balance a 12 inch ruler on your finger, the CG will be at its 6 inch point. If you
change the weight distribution of the ruler by putting a paper clip on one end, then the
balance point (e.g. the CG ) shifts toward the paper clip. Moving from the physical world
to the trading world, we can substitute the prices over our window of observation for the
units of weight along the ruler. With this analogy, we see that the CG of the window
moves to the right when prices increase sharply. Correspondingly, the CG of the
window moves to the left when prices decrease.

Ghosty's Modded Super Bandpass Filter [DasanC]Very cool Indicator from Ehlers and published originally by @DasanC
I made minor modifications, and added a zero line and changed some values. I use this indicator differently then it is intended to be used for scalping shorter time frames (15 min - 1 hour).
I use it like a cross over, either from the zeroline or when it passes the RMS, for 5-10 pips. While no indicator is 100% this one does a nice job for small scalps.
try it out on a demo and see if you like it.
enjoy.

Ehler's Super Smoother 2 and 3 pole (properly initialized)John Ehlers' Super Smoother 2 and 3 pole - properly initialized
www.stockspotter.com
Failure to properly initialize early values of the super smoother will result in misleading values early in the output.
Because the SS is an IIR ( infinite impulse response) filter, this error can ring in the filter for a long time, but
is extremely evident in the first 2*len bars.
This is an implementation if the 2 and 3 pole SS filter, with special attention to initializing the early values.
It uses (src+scr)/2 per Ehlers but contains code to just use src if you prefer to calculate that outside
the function as everget does in his SS here:
there is code included to make that change.
Many thanks to everget for his terrific implementations of much of John Ehlers' work. It has been tremendously helpful to me.
