[blackcat] L1 Ehlers FM DemodulatorLevel: 1
Background
John F. Ehlers introuced FM demodulator of "A Technical Description Of Market Data For Traders" on TASC MAY 2021
Function
John Ehlers introduces the use of FM modulation to determine the cycles of market data. The author also proposes that noise in market data does not necessarily mean chaos and that pink noise in the data implies memory in the data. According to the author, peaks and valleys of the FM demodulator indicator that he presents in the article can be correlated with major swings of the price. The FM demodulator indicator (FMD) ranges from -1.0 to 1.0. There is a natural delay in the detection of peaks and troughs, as we need to wait while the indicator has moved by a certain amount. The example system buys as soon as a new higher trough has been confirmed.
Key Signal
SS --> FM Demodulator ouput
Pros and Cons
100% John F. Ehlers definition translation, even variable names are the same. This help readers who would like to use pine to read his book.

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.

[blackcat] L2 Ehlers Fourier Series StrategyLevel: 2
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.

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.

[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.
