[blackcat] L2 Ehlers Correlation Trend StrategyLevel: 2
Background
John F. Ehlers introuced Correlation Trend Strategy in May, 2020.
Function
In Dr. Ehlers article “Correlation As A Trend Indicator” in May, 2020, he 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. The indicator helps to identify the onset of a trend or to detect the failure of a trend. While his correlation trend indicator measures the price correlation with a rising slope, the new correlation cycle indicator (CCY) measures the correlation with a sine wave .

[blackcat] L2 Ehlers Voss Filter StrategyLevel: 2
Background
John F. Ehlers introuced Voss Filter Strategy in Aug, 2019.
Function
John Ehlers’ mining of the digital signal processing literature space in his article in this issue, “A Peek Into The Future,” brings us another interesting tool for seeing a bit below the noise surrounding price series to better locate turning points. In “A Peek Into The Future” in Aug, 2019, John Ehlers describes the calculation of a new filter that could help signal cyclical turning points in markets. As described by Dr. Ehlers, the 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. Noticing that the indicator accurately tracks the market’s peaks and valleys, Ehlers suggests that simple crossovers of the forward-looking Voss predictor with the two-pole band-pass filter may become the basis of a trading system. Having looked at the paper by Henning Voss, I personally appreciate Ehlers’ ability to reduce the calculus of the Voss presentation to six simple lines of code. I thought that the predictive nature of the VossPredictor would be a good candidate to use for one of the current favorite areas of exploration, self-tuning indicators.

Background
John F. Ehlers introuced Fourier Series Strategy in Jun, 2019.
Function
In “Fourier Series Model Of The Market” in Jun, 2019, John Ehlers introduces a Fourier series indicator designed to help traders identify cycles in the market. According to the author, the approach based on five principles outlined by J.M. Hurst in his 1970 book allows the determinization of a security’s primary cycle period and gives a faithful picture of market activity. It does so by applying a set of band-pass filters. His trading model’s rules are:
## 1. Buy next bar at market open when the FourierSeries(20) has reached a new 200-bar low and then turns up. This is an example of a “self-tuning” model, a concept we’ve been working with recently at Quantacula. Rather than establish an arbitrary oversold level, we use the historical data itself to look for an appropriate reversal level.
## 2. Sell at a limit price equal to the highest two-bar high. We’ve found that this exit works well to capture small gains in markets that are due for an upside move, while reducing exposure.

[blackcat] L2 Ehlers Rocket RSI IndicatorLevel: 2
Background
John F. Ehlers introuced Rocket RSI Indicator in May, 2018.
Function
In “RocketRSI—A Solid Propellant For Your Rocket Science Trading” in May, 2018, John Ehlers introduces a new take on the classic RSI indicator originally developed by J. Welles Wilder. Ehlers begins by introducing a new version of the RSI based on a simple accumulation of up and down closes rather than averages. To this he applies a Fisher transform. He tells us that the resultant output is statistically significant spikes that indicate cyclic turning points with precision.
With this indicator, overbought and oversold conditions are clear:
## Oversold Entry Condition: Indicator crosses value (RocketRSI crosses over -2.00)
## Overbought Exit Condition: Indicator crosses value (RocketRSI crosses under 2.00)
Note the used “crosses under 2.00” for the exit condition, rather than “crosses above 2.00.” This lets the winning positions ride further, and resulted in a better overall return in backtesting.

[blackcat] L2 Ehlers Recursive Median OscillatorLevel: 2
Background
John F. Ehlers introuced Recursive Median Oscillator in Mar, 2018.
Function
In “Recursive Median Filters” in Mar, 2018, John Ehlers presented an approach for filtering out extreme price and volume data that could throw off typical averaging calculations. Dr. Ehlers’ line in digital signal processing extends to removing extreme spikes in financial data, but utilizing the median average value in the recursive filter calculations. By removing these extremities, the actual extremities that occur in the underlying data may be better determined. Ehlers goes on to present a novel oscillator using this technique, comparing its response to the well-known RSI. He notes that by being able to smooth the data with the least amount of lag, the recursive median oscillator may give the trader a better view of the bigger picture.
The recursive median filter (RMF) ignores the spiking-types of the price noise. RMF uses an exponential moving average of the five-period median of the source data to produce a smoothing of the signal while avoiding spikes. The recursive median oscillator (RMO) is an oscillator built along the same principles. The RMO has less lag and a faster response to the larger moves in the price data.

[blackcat] L2 Ehlers Super Passband FilterLevel: 2
Background
John F. Ehlers introuced Super Passband Filter in Jul, 2016.
Function
In “The Super Passband Filter” in Jul, 2016, John Ehlers addressed the problem of frequencies in indicators that are too low or too high. The common practice to refine frequency is to enable smart filters. However, good filters take lots of computational power. So Ehlers showed us how to use filters while keep computing power relatively low. John Ehlers described a new oscillator he’s developed to help minimize computational lag. Ehlers called this new oscillator a super passband filter. He has designed it to reject very low-frequency components and thus display as an oscillator as well as reject high-frequency components so as to minimize noise. Ehlers seeked to filter out both high and low frequencies from market data, eliminating distracting “wiggles” from the resultant signal with minimal lag effect. Trigger points for the filter are added with a root mean square (RMS) envelope over the signal line.
## Buy on the filter crossing above its -RMS line
## Short on the filter crossing below its RMS line
## Exit long when the filter either crosses below its RMS or crosses below -RMS (which signifies a false entry signal)
## Cover short when the filter either crosses above its -RMS or crosses above RMS (which signifies a false entry signal)
It suggests that this new nearly-zero lag filter looks promising for countertrend trades and for buying on significant dips.

Function
In “Decyclers” in Sep, 2015, John Ehlers described a method for constructing an oscillator that could help traders detect trend reversals with almost no lag, an oscillator that signals trend reversals with almost zero lag via digital signal processing techniques. A high-pass filter is subtracted from the input data and the high-frequency components are removed via cancellation of terms. Lower-frequency components are filtered from the output, so they are not canceled from the original data. Thus, the decycler displays them with close to zero lag. The fast line has a period of 100 a K value of 1.2 and the slow line has a period of 125 and a K value of 1.
This script demonstrates the timely response of the decycler oscillator to market action. It applies the idea of using a decycler oscillator pair with different parameters, as discussed in Ehlers’ article:
1. Enter long when the fast line crosses over the slow line;
2. Exit long when the fast line crosses under the slow line.
Key Signal
Fast_Val --> Ehlers Decycler Oscillator fast line
Slow_Val --> Ehlers Decycler Oscillator slow line

[blackcat] L2 Ehlers Simple DecyclerLevel: 2
Background
John F. Ehlers introuced Simple Decycler in Sep, 2015.
Function
In “Decyclers” in Sep, 2015, John Ehlers described a method for constructing an oscillator that could help traders detect trend reversals with almost no lag. Ehlers calls this new oscillator a decycler. The author began the process by isolating the high-frequency components present in the input data. He then subtracted these from the input data leaving only the lower-frequency components representing the trend. In more details, the idea is to subtract the high-pass filter value from the current close to get a “decycled” indicator that follows the trend rather well by removing much of the distracting high-frequency chatter. Apply a second high-pass filter using half the period from the first filter to the decycled indicator and you get a smoother result with much-reduced lag.
Key Signal
Decycle --> Ehlers Simple Decycler signal or center line of band

[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.

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.

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.

Background
John F. Ehlers introuced Empirical Mode Trader Indicator in Mar, 2010.
Function
In his article “Empirical Mode Decomposition,” John Ehlers and Ric Way suggest using methods based on bandpass filtering to distinguish trending from cycling markets. The article’s trading suggestions were used to create the Empirical Mode strategy given here for pine v4 script. If the strategy determines that the marke is in trending mode, then the strategy is allowed to trade with the trend — either long, in uptrends, or short, in downtrends. If the indicator determines that the market is in cycling mode, then the strategy allows trading cycle extremes, using Bollinger bands to trigger entries. You can do this by Choosing either cycle or trend mode at inputs.

Function
In “Zero Lag (Well, Almost)” article, authors John Ehlers and Ric Way presented their zero-lag exponential moving average indicator and strategy. They have adapted their zero-lag EMA by extending the functionality in an additional chart indicator named “Zero-Lag EMA”. Labels were added so that the user can be alerted when a crossing of the averages occurs.
The authors created an error-correcting filter for an exponential moving average ( EMA ) that seeks to minimize the lag effect of increasing periods. Increasing the gain parameter from zero changes the filter from an EMA with lag to effectively zero lag (albeit with zero smoothing also). The crossover of these lines can be used to form a trading strategy, with the addition of some threshold value for the difference between the Price and error-correcting line.

In "Measuring Cycle Periods" in Mar, 2008, John Ehlers presented a very interesting technique of measuring dominant market cycle periods by means of multiple bandpass filtering. By utilizing an approach similar to audio equalizers, the signal (here, the price series) is fed into a set of simple second-order infinite impulse response bandpass filters. Filters are tuned to 8,9,10,...,50 periods. The filter with the highest output represents the dominant cycle. This script implements a high-pass filter and a six-tap low-pass Fir filter on input, then 42 parallel Iir band-pass filters. Finally, it plots the Ehlers spectrogram as a heat map.
Ehlers Spectrogram indicates market power status:
With high market power, the spectrogram become fuzzy;
With low market power, the spectrogram become distinct.
It also discloses market dominant cycles and subcycles, which indicates the major rhythm. Regarding the rhythm of the market, Chinese and Western cultures have reached a consensus: Dr. Ehlers can find the main harmonic components of the market through DSP analysis via spectrum; Master Zen compares the market rhythm to Bach’s fugue from a philosophical perspective, where there is a rhythm of life.
Finally, please allow me to quote Master Zen’s statement on market rhythm:
"The market is cruel. For those who try to violate the market rhythm, the market is their death place; the market is beautiful, and the market is Bach’s fugue. There is a rhythm of life. Rhythm is always the rhythm of the market. A market participant without a sense of rhythm is always torturing. Put aside your greed and fear and listen to the rhythm of the market. In the weekend, let go of everything, but listen to the rhythm of nature, the rhythm of life, the rhythm of music, and then come back to listen to the rhythm of the market. Dancing with the market, your greed and fear are peeled off one by one, you will become very bright."

Readme
In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.
The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.
Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.
Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.
Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. 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.
