[blackcat] L2 The Distance Coefficient Ehlers FilterLevel: 2
Background
John F. Ehlers introuced the Distance Coefficient Ehlers Filter in his "Rocket Science for Traders" chapter 18 on 2001.
Function
Dr. Ehlers considered the gray shading levels as distances, he had away of computing filter coefficients in terms of sharpness of the edge. White is the maximum distance in one direction from the median gray, and black is the maximum distance in the other direction. In this sense, distance is a measure of departure from the edge, taking into account the edge sharpness. Transitioning to price charts, the difference in prices can be imagined as a distance. Recalling the Pythagorean Theorem (which the length of the hypotenuse of a triangle is equal to the sum of the squares of the lengths of the other two sides), Dr Ehlers applied it to the needs and say that a generalized length at any data sample is the square root of the sum of the squares of the price difference between that price and each of the prices back for the length of the filter window. The distances squared at each data point are the coefficients of the Ehlers filter.

[blackcat] L2 Ehlers FilterLevel: 2
Background
John F. Ehlers introuced Ehlers Filter in his "Rocket Science for Traders" chapter 18 on 2001.
Function
blackcat L2 Ehlers Filter is used to follow trend. The filters Dr. Ehlers have invented are nonlinear FIR filters. It turns out that they provide both extraordinary smoothing in sideways markets and aggressively follow major price movements with minimal lag. The development of Ehlers filters starts with a general
class of FIR filters called Order Statistic (OS) filters. These filters are well-known for speech and image processing, to sharpen edges, increase contrast, and for robust estimation. In contrast to linear filters, where temporal ordering of the samples is preserved, OS filters base their operation on the ranking of samples
within the filter window. The data are ranked by their summary statistics, such as their mean or variance, rather than by their temporal position.
Among OS filters, the Median filter is the best known. In a Median filter, the output is the median value of all the data values within the observation window. As opposed to an averaging filter, the Median filter simply discards all data except the median value. In this way, impulsive noise spikes and extreme price data are eliminated rather than included in the average. The median value can fall at the first sample in the data window, at the last sample, or anywhere in between. Thus, temporal characteristics are lost. The Median filter tends to smooth out short-term variations that lead to whipsaw trades with linear filters. However, the lag of a Median filter in response to a sharp and sustained price movement is substantial --- it necessarily is about half the filter window width.

[blackcat] L2 Ehlers MAMALevel: 2
Background
John F. Ehlers introuced MESA Adaptive Moving Average-a.k.a "MAMA" in his "Rocket Science for Traders" chapter 17. Forgive the whimsy of the name Dr. Ehlers attached to this unique indicator, but with that name he is sure you will always remember it, like KAMA and VIDYA.
Function
blackcat L2 Ehlers MESA Adaptive Moving Average-a.k.a "MAMA" is used to follow trend. The concept of MAMA is to relate the phase rate of change to the EMA alpha, thus making the EMA adaptive. The cycle phase goes from 0 through 360 degrees in each cycle. The phase is continuous, but is usually drawn with the snap back to 0 degrees as the beginning of each cycle. Thus the phase rate of change is 360 degrees per cycle. The shorter the cycle, the faster the phase rate of change. For example, a 36-bar cycle has a phase rate of change of 10 degrees per bar, while a 10-bar cycle has a rate of change of 36 degrees per bar. The cycle periods tend to be longer when the market is in a Trend Mode.
The cycle phase is computed from the arctangent of the ratio of the Quadrature component to the Inphase component. Dr. Ehlers obtain the phase rate of change values by taking the difference of successive phase measurements. The arctangent function only measures phase over a half cycle, from -90 degrees to +90 degrees. Since the phase measurement snaps back every half cycle, a huge negative rate change of phase every half cycle results from the computation of the rate change of phase. Measured negative rate changes of phase can also occur when the market is in a Trend Mode. Any negative rate change of phase is theoretically impossible because phase must advance as time increases. Dr. Ehlers therefore limit all rate change of phase to be no less than unity.

[blackcat] L2 Ehlers Market Mode IdentifierLevel: 2
Background
John F. Ehlers introuced Market Mode Identifier in his "Rocket Science for Traders" chapter 11. The simplified model of the market, derived from the Drunkard's Walk problem, has only two modes-the Cycle Mode and the Trend Mode. Through the derivation of the Sinewave Indicator and the Instantaneous Trendline, Ehlers had shown several ways to estimate which mode the market may have for a given moment. As with most technical indicators, the decision point between modes is not clear-cut. In fact, trying to automate the decision often leads to a great deal of chatter and rapid back and
forth switching of decisions.
Function
blackcat L2 Ehlers Market Mode Identifier is used to identify market status is in Trend Mode or Cycle Mode.Since the Cycle Mode exists for the smallest fraction of time and since most traders make the most money following a trend rather than a cycle, it is best to assume that the market is in a Trend Mode unless some very specific criteria are met. There are only two criteria to establish a Cycle Mode. First, a Cycle Mode exists for the period of a half-dominant cycle after the crossing of the two Sinewave Indicator lines. Second, a Cycle Mode exists if the measured phase rate of change is more than two-thirds the phase rate of change of the dominant cycle (2*pi /Period) and is less
than 1.5 times the phase rate of change of the dominant cycle. There is another condition that defines a Trend Mode. This condition is derived from pragmatic observation, not theoretical considerations. When the market makes a major reversal, it often does this with great vigor. When this occurs, the prices have a wide separation from the Instantaneous Trendline. When the prices are widely separated from the Instantaneous Trendline, it is possible for the Cycle Mode conditions to be met-but the Cycle Mode identification is clearly incorrect. Dr. Ehlers have therefore inserted another overriding rule for these cases. That rule is that if the SmoothPrice (the 4-bar WMA of the Price) is separated by more than 1.5 percent from the Instantaneous Trendline, then the correct market mode is the Trend Mode.

[blackcat] L2 Ehlers Instantaneous TrendlineLevel: 2
Background
John F. Ehlers introuced Instantaneous Trendline (IT) in his "Rocket Science for Traders" chapter 10. Dr. Ehlers hope IT can enable us to compute a continuous trendline from which we can rapidly assess market action.
Function
blackcat L2 Ehlers Instantaneous Trendline (IT) is used to follow trend. IT is important because the dominant cycle component is always notched out. It follows that if the composite analytic waveform consists of only a trend component and a cycle component, and if we remove the cycle component, the residual must be the trend. Of course, this is not precisely true in reality, because there will always be components other than the dominant cycle present. However, this is a workable solution for trading purposes because the secondary cycles usually have a small amplitude.

[blackcat] L2 Ehlers Sine Wave IndicatorLevel: 2
Background
John F. Ehlers introuced Sine Wave Indicator in his "Rocket Science for Traders" chapter 9.
Function
blackcat L2 Ehlers Sine Wave Indicator compared to conventional oscillators such as the Stochastic or Relative Strength Indicator (RSI), the Sinewave Indicator has two major advantages. These are
1. The Sinewave Indicator anticipates the Cycle Mode turning point rather than waiting for confirmation.
2. The phase does not advance when the market is in a Trend Mode. Therefore, the Sinewave Indicator tends to not give false whipsaw signals when the market is in a Trend Mode.
An additional advantage is that the anticipation signal is obtained strictly by mathematically advancing the phase. Momentum is not employed. Therefore, the Sinewave Indicator signals are no more noisy than the original signal.
Key Signal

[blackcat] L2 Ehlers Hilbert OscillatorLevel: 2
Background
John F. Ehlers introuced Hilbert Oscillator in his "Rocket Science for Traders" chapter 8. The Hilbert Oscillator identifies every major turning point.
Function
blackcat L2 Ehlers Hilbert Oscillator is used to follow the trend. Although it will not be a leading indicator because of the 2-bar lag required to compute Q3, it does prove itself to be superior to most currently available oscillators. The bandwidth for the computation of Value1 is twice the bandwidth of I3. Therefore, the amplitude compensation will be less, approximately the square root of 1.57, which is about 1.25. The Hilbert Oscillator identifies every major turning point.

[blackcat] L2 Ehlers Enhanced Signal to Noise IndicatorLevel: 2
Background
John F. Ehlers introuced another Enhanced Signal to Noise Indicator in his "Rocket Science for Traders" chapter 8.
Function
blackcat L2 Ehlers Signal to Noise Indicator is used to measure Signal-to-Noise Ratio (SNR). In this code, the period of the measured dominant cycle is calculated in exactly the same manner as we calculated it for the Primary SNR Indicator. Near the end of the code, after the dominant cycle is determined, Dr. Ehlers computes the SNR. The Quadrature component Q3 is calculated by multiplying the 2-bar momentum of the Weighted Moving Average (WMA) smoothing by the dominant cycle amplitude correction factor.

[blackcat] L2 Ehlers Signal to Noise IndicatorLevel: 2
Background
John F. Ehlers introuced Signal to Noise Indicator in his "Rocket Science for Traders" chapter 8. Dr. Ehlers terms the case where half the average daily trading range is equal to the signal amplitude as our zero decibel Signal-to-Noise Ratio (0 dB SNR) condition. He wants the signal amplitude to be at least twice the noise amplitude (6dB SNR) so that there exists a reasonable chance to make a profit from the chart analysis.
Function
blackcat L2 Ehlers Signal to Noise Indicator is used to measure Signal-to-Noise Ratio (SNR). The SNR in decibels is calculated in a single line of code near the end. The signal power is divided by the noise power to get a power ratio. The logarithm of the power ratio. At 0 dB, the peak-to-peak noise signal is twice the amplitude of the signal. Therefore, when we compute the 0 dB case, the ratio is calculated to be 10*log(1/2)^2 = -6 dB. We must then add 6 dB back into the computation to remove this bias, establishing the definition of 0 dB SNR.

[blackcat] L2 Ehlers Dual Differential Cycle Period MeasurerLevel: 2
Background
John F. Ehlers introuced Dual Differential Cycle Period Measurer in his "Rocket Science for Traders" chapter 7. The In-phase and Quadrature components are computed with the Hilbert Transformer using procedures identical to those in the Dual Differentiator.
Function
blackcat L2 Ehlers Homodyne Discriminator Cycle Period Measurer is used to measure Dominant Cycle (DC). This is one of John Ehlers three major methods to measure DC. These components undergo a complex averaging and are smoothed in an EMA to avoid any undesired cross products in the multiplication step that follows. The period is solved directly from the smoothed Inphase and Quadrature components. The interim calculation for the denominator is performed as Value1 to ensure that the denominator will not have a zero value. The sign of Valuel is reversed relative to the theoretical equation because the differences are looking backward in time.
Key Signal
Smooth --> 4 bar WMA w/ 1 bar lag

[blackcat] L2 Ehlers Homodyne Discriminator Period MeasurerLevel: 2
Background
John F. Ehlers introuced Homodyne Discriminator Cycle Period Measurer in his "Rocket Science for Traders" chapter 7. Homodyne means we are multiplying the signal by itself. More precise, we want to multiply the signal of the current bar with the complex conjugate of the signal 1 bar ago. The complex conjugate is, by definition, a complex number whose sign of the imaginary component has been reversed.
Function

[blackcat] L2 Ehlers Phase Accumulator Cycle Period MeasurerLevel: 2
Background
John F. Ehlers introuced Phase Accumulation technique of cycle period measurement in his "Rocket Science for Traders" chapter 7. It is perhaps the easiest to comprehend. In this technique, John Ehlers measures the phase at each sample by taking the arctangent of the ratio of the Quadrature component to the In-phase component. A delta phase is generated by taking the difference of the phase between successive samples. At each sample Dr. Ehlers then looks backward, adding up the delta phases. When the sum of the delta phases reaches 360 degrees (2*pi in tradingview), we must have passed through one full cycle, on average. The process is repeated for each new sample.
Function
blackcat L2 Ehlers Phase Accumulator Cycle Period Measurer is used to measure Dominant Cycle (DC). This is one of John Ehlers three major methods to measure DC. The Phase Accumulation method of cycle measurement always uses one full cycle’s worth of historical data. This is both an advantage and disadvantage. The advantage is the lag in obtaining the answer scales directly with the cycle period. That is, the measurement of a short cycle period has less lag than the measurement of a longer cycle period. However, the number of samples used in making the measurement means the averaging period is variable with cycle period. Longer averaging reduces the noise level compared to the signal. Therefore, shorter cycle periods necessarily have a higher output Signal-to-Noise Ratio (SNR).

[blackcat] L2 Ehlers Hilbert TransformLevel: 2
Background
John F. Ehlers introuced Hilbert Transform in his "Rocket Science for Traders" chapter 6. The Hilbert Transform is a procedure to create complex signals from the simple chart data familiar to all traders. Once we have the complex signals, we can compute indicators and signals that are more accurate and responsive than those computed using conventional techniques. In fact, some of the indicators we will discuss cannot be calculated at all without the Hilbert Transform.

[blackcat] L2 Ehlers Sine Wave Coupled Eight Planetary CycleLevel: 2
Background
Have you considered that factors outside the Earth will be related to macro market trends? Let’s discuss the relationship between the planetary movement in the Galaxy and the market movement on Earth today! Although I said that, you may have laughed out in front of the screen, but the calculations in this script are entirely based on astronomical data and mathematical relationships.
Your next question may be why you compare the movements of the eight planets and the laws of the market on the earth together? My answer comes from a Cybernetic Sine Wave indicator proposed by Dr. John F. Ehlers.
Function
L2 Ehlers Sine Wave Coupled Eight Planetary Cycle first converts the astronomical data of the eight major planets into planetary aspects/phases through mathematical relationships. Planetary aspects/phases can provide the historical and current relative positions of each planet in the mathematical triangle relationship. We can use a simple mathematical sine formula to constrain the planet's trajectory between -1 and 1, which is what we often call a sine wave.
The relationship between the sine wave and the market can be extracted from the theory of John F. Ehlers. In Ehlers' theory, market price can be modeled by the trend and cycle modes. And in his works, there are many indicators of how to completely remove the trend in the market price and only leave the cycle mode data. The Cybernetic Sine Wave indicator is exactly the cycle mode data after the market trend is stripped, and expressed in the form of a sine wave.
If you can read to here with patience, you must also be aware of the premise that the trajectories of the eight planets and the laws of the earth market can be coupled: the trajectory of the sine wave mode. Therefore, this indicator is a tool for comparing and analyzing the two in the same chart. I hope you like it.
Finally, in order to benchmark the trajectories of the eight planets and the specific market on the earth, a starting point in time is particularly important. This is the base date of the market index to be analyzed. It is the year, month, and day data specified by the index, which needs to be input by the user when analyzing a specific stock index. For example, the base date of the S&P 500 index is January 3, 1928. This date needs to be entered into the indicator to analyze the SPX500.

Ehlers Adaptive Commodity Channel Index V1 [CC]The Adaptive Commodity Channel Index V1 was created by John Ehlers (Rocket Science For Traders pgs 236-237) and this is the typical Commodity Channel formula with the introduction of adaptive lengths based on his earlier work with indicators such as the Mother of Adaptive Moving Averages. For longer term signals you would get a bullish signal when CCI is above 0 and a bearish signal when CCI falls below 0. For shorter term signals you would get a bullish signal when crosses over it's overbought level or when it crosses above it's oversold level or vice versa. I have included both signals to make it easier.
Let me know if you want a custom script written or if you have a special request for me
Ehlers Adaptive Relative Vigor Index [CC]The Adaptive Relative Vigor Index was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 140-141) and it does a pretty good job of capturing the peaks and valleys of the underlying data. There are several ways to read this particular indicator so for long term trades then buy when it goes above 0 and sell when it falls below 0 or for shorter term trades then buy when the indicator line turns green and sell when it turns red.
Let me know if there are other indicators you would like to see me publish or if you want something custom done!
Ehlers Trend Vigor NormalizedThanks to MasBart, I updated the earlier version to normalize signal and lead according to vigor and trigger. Vigor and trigger are limited to +-2. Now signal and lead are also in that range.
The code of interest is lines 39-43:
tmpdif = (BP - nz(BP ))/close
a = array.new_float(0)
for i = 0 to win-1
array.push(a, tmpdif )
den = array.max(a)
den is then used to normalize the BP values (bandpass filter).
Ehlers Trend VigorThis approach is from Dr. John Ehlers:
The trend vigor indicator is not the same as the Relative Vigor Index (RVI). Trend Vigor measures the strength of the trend relative to the cycle. The larger the value of the Trend Vigor, the more powerful the trend is relative to the cycle.
The trend vigor is the slope of the close (or any other price input) over one full dominant cycle divided by the amplitude of the dominant cycle.
Typical Approach:
offset = measured dominant cycle
close - close /amplitude
The amplitude is more complicated. It is defined as:
sqrt( (InPhase * Inphase) + (Quadrature * Quadrature) )
The Inphase and Quadrature are components derived when calculating the dominant cycle. Detailed discussion of the InPhase and Quadrature components can be found in Ehler's book, "Rocket Science for Traders" in the chapter discussing the Homodyne Discriminator dominant cycle calculation.
Ehlers 3 Pole Butterworth Filter V2 [CC]The 3 Pole Butterworth Filter was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 196-197) and this indicator is a moving average that also works well as a trendline. Buy when the indicator line turns green and sell when it turns red.
Let me know if you would like me to publish other indicators or if you want something custom done!
Ehlers 2 Pole Super Smoother Filter V2 [CC]The 2 Pole Super Smoother Filter was created by John Ehlers (Cycle Analytics For Traders pg 32) and this follows the price very closely and very useful because it is consistent with uptrends and falls sharply during a sudden downtrend so it should be able to help you stay more profitable. Buy when the indicator line turns green and sell when it turns red.
Let me know if there are other indicators you would like to see me publish or if you want something custom done!
Ehlers Center Of Gravity Oscillator [CC]The Center of Gravity Oscillator was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pg 49) and this provides a pretty accurate way to see how the stock is trending. If the indicator stays above 0 then the stock is in a pretty strong uptrend and if it stays below 0 then the stock is in a pretty strong downtrend. Buy when the indicator changes from red to green and sell when it changes from green to red.
Let me know if you would like me to publish any other indicators or if you want something custom done!
