[blackcat] L2 Ehlers Universal OscillatorLevel: 2
Background
John F. Ehlers introuced Universal Oscillator in Jan, 2015.
Function
In “Whiter Is Brighter”, in Jan 2015, John Ehlers presented a new indicator he calls the universal oscillator. It is based on his theory that market data resembles pink noise, or as he puts it, “noise with memory.” It could be used to create a short-term trading strategy. I modified it a little bit by changing the scan criteria that is met when the universal oscillator crosses above or below a pair of threshold values e.g. +/- 0.85. Therefore, a straightforward short-term (small time scale) countertrend system could, for example, use the following rules:
## Cover your short position and go long when the universal oscillator crosses below zero or a overbought/oversold threholds e.g. +/- 0.85; sell and go short when the universal oscillator crosses above zero or a overbought threhold e.g. + 0.85.
Since it is really a universal oscillator, the indicator can power up a trend-trading system just as easily:
## Buy when the long-term universal oscillator crosses above zero or a oversold threshold e.g. - 0.85.
## Sell when the long-term universal oscillator crosses below zero or a overbought threshold e.g. 0.85.

[blackcat] L2 Ehlers Super Smooth Stoch StrategyLevel: 2
Background
John F. Ehlers introuced Super Smooth Stochastic Indicator in Jan, 2014.
Function
In “Predictive And Successful Indicators” of in, 2014, John Ehlers presented another innovative way to eliminate noise from classic indicators and introduces some new smoothing indicators: the SuperSmoother filter, which is superior to moving averages for removing aliasing noise, and the MESA Stochastic oscillator, a stochastic successor that removes the effect of spectral dilation through the use of a roofing filter.
John Ehlers described a new method for smoothing market data while reducing the lag that most other smoothing techniques have. Ehlers had provided an approach for creating a strategy. For convenience, I made the same code available at tradingview pine v4 as well as an example strategy based on Ehlers’ description. Ehlers introduced a simple countertrend system that goes long when MESA Stochastic crosses below the oversold value and reverses the trade by taking a short position when the oscillator exceeds the overbought threshold.

Background
John F. Ehlers introuced Enhaced Corona Swing Position Indicator in April, 2012.
Function
John Ehlers's corona indicators, "Corona Charts," provide a "multidimensional" view of market activity. In the article "Corona Charts" in Nov, 2008, John Ehlers further developed his earlier work on market cycles. A new kind of indicator was presented that uses a glow-like effect to present another dimension of data. Implementation of corona charts in pine v4 helps detect dominant cycles in data. It provides a corona chart for swing positions indicator. He made an enhanced version of corona chart after 4 years, which could be used as a range filter to detect sideways and trends. Dr . Ehlers claims that a corona is displayed when the market is in a trend and there is little cyclic component. The swing position indicator shows the phasing of the data within the dominant cycle. In a pure cycle the Swing Position will trace out the shape of a sine wave.

[blackcat] L2 Ehlers Zero-lag SmootherLevel: 2
Background
John F. Ehlers introuced Zero-Lag Data Smoothers in Jul, 2002.
Function
John Ehlers introduced "Zero-Lag Data Smoothers", the infinite impulse response (IIR) filter and finite impulse response (FIR) filter.
In his article this issue on zero-lag smoothing, John Ehlers notes that his favorite filter is the symmetrically weighted six-bar finite impulse response (FIR) filter. This is also known as a triangular moving average, and can be conveniently implemented as a double-smoothed simple moving average. Per Ehlers, since this filter has six elements, its lag is 2.5 bars. Via further processing, this lag can be reduced to zero, but this produces too much overshoot. As a compromise, Ehlers suggests reducing the lag to one bar. To enable a user to adjust the lag easily, I provide the pine v4 code for an Adjustable Lag Filter indicator below. The first input, Price, should typically be set to OHLC, hl2, hl3, ohlc4 etc. The second input, LagReduction, should be set to a value in the zero-to-2.5 range. Setting it to zero will result in no adjustment, and the output will match that of the raw triangular average. Setting it to 2.5 will reduce the lag to zero. Setting it to 1.5 will reduce the lag to one bar.

[blackcat] L2 Ehlers Swiss Army KnifeLevel: 2
Background
John F. Ehlers introuced swiss army knife (SAK)indicator in 2005.
Function
The swiss army knife (SAK)indicator does all the common functions of the usual indicators, such as smoothing and momentum generation. It also does some unusual things, such as band stop and band reject filtering. Once you program this indicator into your trading platform you can do virtually any technical analysis technique with it. This unique general indicator results from general Digital Signal Processing (DSP) concepts for discrete signal networks that appear in various forms in technical analysis .
The description of this indicator involves Z Transforms. Z Transforms are a convenient way of solving difficult difference equations in much the same way as LaPlace Transforms are used to solve differential equations in calculus. Difference equations arise from the use of sampled data, such as we have in technical analysis . That is, daily bars sample price data once a day. Intraday bars sample price data every minute, hour, or whatever. The concept is the same regardless of the sampling rate. In Z Transforms, Z^(-1) stands for one sample period of delay. For simplicity, I will always refer to daily bars as the sample rate.
It includes,
1. Exponential Moving Average ( EMA )
2. Simple Moving Average ( SMA )
3. Two Pole Gaussian Filter
4. Two Pole Butterworth Filter
5. High Pass Filter
6. Two Pole High Pass Filter
7. BandPass Filter
8.BandStop Filter
The Swiss Army Knife Indicator is a versatile approach that creates a wide variety of responses that range from smoothers to oscillators. Novel BandPass and BandStop filters can also be produced. All of this can be done with one line of code in most platforms. The various responses come from the coefficients that can be called – as functions if you prefer.

Background
John F. Ehlers introuced Measuring the Dominant Cycle using the HomoDyne Discriminator in his "Cycle Analytics for Traders" chapter 14 on 2013.
Function
With Hilbert transformer, the third algorithm for computing the dominant cycle is the homodyne approach. Homodyne means the signal is multiplied by itself. More precisely, we want to multiply the signal of the current bar with the complex value of the signal one bar ago. The complex conjugate is, by definition, a complex number whose sign of the imaginary component has been reversed.

John F. Ehlers introuced Hilbert Transformer Indicator in his "Cycle Analytics for Traders" chapter 14 on 2013.
Function
Basically, the real component moves with the general direction of the prices, and the imaginary component is a predictive indicator for the real component in the same sense that a cosine wave is a predictor of a sine wave. Although the default LPPeriod input is set to 20 bars in an attempt to smooth the indicator the imaginary component is still too erratic to be useful.
Key Signal

[blackcat] L2 Ehlers Classic Hilbert TransformerLevel: 2
Background
John F. Ehlers introuced Classic Hilbert Transform in his "Cycle Analytics for Traders" chapter 14 on 2013. 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.
Function

[blackcat] L2 Ehlers Convolution IndicatorLevel: 2
Background
John F. Ehlers introduced Convolution Indicator in his "Cycle Analytics for Traders" chapter 13 on 2013.
Function
Since high correlation exists only at the market turning point, the convolution indicator is dependent on the lookback period used in the calculation. Assuming the two price segments have an equal time duration, the peak correlation occurs at half the lookback period of the indicator. For example, if a 13-bar period is used, the market peak would appear with a 7-bar delay. The same market peak would appear with a 19-bar delay if a 39-bar lookback period were used in the convolution computation.
Key Signal

[blackcat] L2 Ehlers Roofing Filter IndicatorLevel: 2
Background
John F. Ehlers introuced Roofing Filter Indicator in his "Cycle Analytics for Traders" chapter 7 on 2013.
Function
The roofing filter does an excellent job of using only the frequency components between its upper and lower critical periods. All that needs to be done to create an indicator from the roofing filter is to add more generality by allowing the high-pass and low-pass critical periods be supplied as indicator inputs. The two high-pass filters have been implemented as a single two-pole high-pass filter. The ideal time to buy is when the cycle is at a trough, and the ideal time to exit a long position or to sell short is when the cycle is at a peak. These conditions are flagged by the filter crossing itself delayed by one bar, and are included as part of the indicator.

[blackcat] L2 Ehlers Zero Mean Roofing FilterLevel: 2
Background
John F. Ehlers introuced Zero Mean Roofing Filter in his "Cycle Analytics for Traders" chapter 7 on 2013.
Function
The HP-LP Roofing Filter output still contains all of these frequency components. The only way we can reduce the effect of these lower-frequency components is to introduce another high-pass filter, adding an additional 6 dB per octave roll-off, so that the net effect of the filter is as originally surmised. Dr. Ehlers have added Filt2 to the code in "Zero Mean Roofing Filter". Note that in addition to establishing a nominally zero mean, removal of the longer cycle components caused by spectral dilation removes lag from the roofing filter output.

[blackcat] L2 Ehlers HP-LP Roofing FilterLevel: 2
Background
John F. Ehlers introuced HP-LP Roofing Filter in his "Cycle Analytics for Traders" chapter 7 on 2013.
Function
A “roofing filter” can be used to limit the frequency content of an input before proceeding to construct an indicator. The roofing filter is composed of a highpass filter that passes only frequency components whose periods are shorter than 48 bars, for example. It also is composed of a SuperSmoother filter that passes frequency components whose periods are longer than 10 bars. Thus, the roofing filter is a wide bandwidth band-pass filter that passes only frequency components whose periods fall between 10 bars and 48 bars. This, by itself, is a simple indicator.
While the roofing filter indicator wiggles in proportion to the wiggles in the price data as you would expect, it is noticeable that the indicator is above zero for extended periods where the market is in an uptrend. In other words, the filter output does not have a zero mean as you would expect if the output consisted only of cyclic components whose periods fall between 10 bars and 48 bars.

[blackcat] L2 Ehlers Bandpass FilterLevel: 2
Background
John F. Ehlers introuced Bandpass Filter in his "Cycle Analytics for Traders" chapter 5 on 2004.
Function
After declaring variables, the band-pass filter calculation is preceded by a high-pass filter whose cutoff frequency is one half-bandwidth octave below the lower-frequency critical frequency of the band-pass filter to avoid interference with the action of the band-pass filter while still removing the effects of Spectral Dilation.

[blackcat] L2 Ehlers Decycler OscillatorLevel: 2
Background
John F. Ehlers introuced Decycler Oscillator in his "Cycle Analytics for Traders" chapter 4 on 2004.
Function
A decycler oscillator is created by subtracting the output of a high-pass filter having a shorter cutoff period from the output of another high-pass filter having a longer cutoff period. This way, both elements have a zero in their transfer responses at zero frequency. Thus, the very, very long cycle components (and the static term) are removed. There is a finite difference between the output of the two filters in the frequency range between their cutoff periods, but shorter cycle components are still removed by cancellation. As a result, the trend line is displayed as an oscillator.

[blackcat] L2 Ehlers DecyclerLevel: 2
Background
John F. Ehlers introuced Decycler in his "Cycle Analytics for Traders" chapter 4 on 2004.
Function
The concept of a decycler is really pretty simple. The cyclic components are removed by the process of cancellation. If the high-pass filter output is subtracted from the input data, the residual only contains the low-frequency components. The decycler is a one-pole filter because the denominator contains only a first-order polynomial. By examination, the decycler must closely follow the input data because there is no difference term in the numerator of the transfer response.

[blackcat] L2 Ehlers Leading IndicatorLevel: 2
Background
John F. Ehlers introuced Leading Indicator in his "Cybernetic Analysis for Stocks and Futures" chapter 16 on 2004.
Function
The leading characteristic is present in the net filte.As predicted, the lead is one bar at very low frequencies. That is, the trend indication will lead by one bar. However, the net filter has a lag of approximately 2.5 bars for cycle components near 20-bar cycles. Also, higher-frequency lag settles down to be about half a bar. The interpretation of the lag response is that the filter predicts a continuation of a trend by 1 bar, lags abrupt changes by about 0.5 bars, and lags smooth changes that can be fitted by segments of a 20-bar sinewave by as much as 2.5 bars. That’s the law of physics—you cannot get something for nothing. Causal filters can have a predictive capability over some portion of the frequency response, but not at all frequencies. There is no magic predictor.

“Truth and science always triumph over ignorance and superstition.” said by Dr. Ehlers. We can generate superior smoothing with very short filters, it follows that we should be able to create superior indicators using very short data lengths also. The use of shorter data lengths means that we can make the indicators more responsive to changes in the price. The Laguerre RSI will be used as an example.

Background
John F. Ehlers introuced Laguerre Filter in his "Cybernetic Analysis for Stocks and Futures" chapter 14 on 2004.
Function
The Laguerre transform can be represented as an exponential moving average (EMA) low-pass filter (the first term) followed by a succession of allpass elements instead of unit delays (the k − 1 terms). All terms have exactly the same damping factor γ (gamma). We see that these are all pass networks by examining the frequency response. Dr. Ehlers made a filter using the Laguerre elements instead of the unit delay, whose coefficients are also /6 as with the FIR filter. The difference is that we have warped the time between the delay line
taps.

Even some interesting fundamental and mass psychological aspects are incorporated.
Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.
Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.
