Fancy Oscillator Screener [Daveatt]⬛ OVERVIEW
Building upon LeviathanCapital original RSI Screener (), this enhanced version brings comprehensive technical analysis capabilities to your trading workflow. Through an intuitive grid display, you can monitor multiple trading instruments simultaneously while leveraging powerful indicators to identify market opportunities in real-time.
⬛ FEATURES
This script provides a sophisticated visualization system that supports both cross rates and heat map displays, allowing you to track exchange rates and percentage changes with ease. You can organize up to 40 trading pairs into seven customizable groups, making it simple to focus on specific market segments or trading strategies.
If you overlay on any circle/asset on the chart, you'll see the accurate oscillator value displayed for that asset
⬛ TECHNICAL INDICATORS
The screener supports the following oscillators:
• RSI - the oscillator from the original script version
• Awesome Oscillator
• Chaikin Oscillator
• Stochastic RSI
• Stochastic
• Volume Oscillator
• CCI
• Williams %R
• MFI
• ROC
• ATR Multiple
• ADX
• Fisher Transform
• Historical Volatility
• External : connect your own custom oscillator
⬛ DYNAMIC SCALING
One of the key improvements in this version is the implementation of dynamic chart scaling. Unlike the original script which was optimized for RSI's 0-100 range, this version automatically adjusts its scale based on the selected oscillator.
This adaptation was necessary because different indicators operate on vastly different numerical ranges - for instance, CCI typically ranges from -200 to +200, while Williams %R operates from -100 to 0.
The dynamic scaling ensures that each oscillator's data is properly displayed within its natural range, making the visualization both accurate and meaningful regardless of which indicator you choose to use.
⬛ ALERTS
I've integrated a comprehensive alert system that monitors both overbought and oversold conditions.
Users can now set custom threshold levels for their alerts.
When any asset in your monitored group crosses these thresholds, the system generates an alert, helping you catch potential trading opportunities without constant manual monitoring.
em will help you stay informed of market movements and potential trading opportunities.
I hope you'll find this tool valuable in your trading journey
All the BEST,
Daveatt

Weekly COTAdjusted COT Index
Improves upon: "COT Index Commercials vs large and small Speculators" by SystematicFutures
How: CoT Indexes are adjusted by Open Interest to normalise data over time, and threshold background colours are in-line with Larry Williams recommendations from his book.
Note: This indicator is **only** accurate on the Daily time-frame due to the mid-week release date for CoT data.
This script calculates and plots the Adjusted Commitment of Traders (COT) Index for Commercial, Large Speculator, and Retail (Small Speculator) categories.
The CoT Index is adjusted by Open Interest to normalise data through time, following the methodology of Larry Williams, providing insights into how these groups are positioned in the market with an arguably more historically accurate context.
COT Categories
-------------------
- Commercials (Producers/Hedgers): Large entities hedging against price changes in the underlying asset.
- Large Speculators (Non-commercials): Professional traders and funds speculating on price movements.
- Retail Traders (Nonreportable/Small Speculators): Small individual traders, typically less informed.
Features
----------
- Open Interest Adjustment
- The net positions for each category are normalized by Open Interest to account
for varying contract sizes.
- Customisable Look-back Period
- You can adjust the number of weeks for the index calculation to control the
historical range used for comparison.
- Thresholds for Extremes
- Upper and lower thresholds (configurable) are provided to mark overbought and
oversold conditions.
- Defaults
- Overbought: <=20
- Oversold: >= 80
- Hide Current Week Option
- Optionally hide the current week's data until market close for more accurate comparison.
- Visual Aids
- Plot the Commercials, Large Speculators, and Retail indexes, and optionally highlight extreme positioning.
Inputs
--------
- weeks
- Number of weeks for historical range comparison.
- upperExtreme and lowerExtreme
- Thresholds to identify overbought/oversold conditions (default 80/20).
- hideCurrentWeek
- Option to hide current week's data until market close.
- markExtremes
- Highlight extremes where any index crosses the upper or lower thresholds.
- Options to display or hide indexes for Commercials, Large Speculators, and Small Speculators.
Outputs
----------
- The script plots the COT Index for each of the three categories and highlights periods of extreme positioning with customisable thresholds.
Usage
-------
- This tool is useful for traders who want to track the positioning of different market participants over time.
- By identifying the extreme positions of Commercials, Large Speculators, and Retail traders, it can give insights into market sentiment and potential reversals.
- Reversals of trend can be confirmed with RSI Divergence (daily), for example
- Continuation can be confirmed with RSI overbought/oversold conditions (daily), and/or hidden RSI Hidden Divergence, for example
Flush Percent RangeFans of Woodies CCI may recognize the approach to this one. This is my attempt at using the same methods but for taking the highs and lows into account without the standard deviation of the CCI. The smoothness of other oscillators may not be ideal however the Williams Percent Range is a fast stochastic that also operates within a channel. This provides an alternative yet still complex view for the virtuoso. A unique feature is total utilization of the weighted moving average, from the standard to the more complex. A fun fact is the Hull Moving Average is actually calculated using weighted moving averages.
How to use:
The base length is for accuracy, the fast length is for catching all the moves(even the wrong ones sometimes.)
The bars back option will not flip the histogram/base trend to its bullish/bearish alternative until the base plot remains on the latter half of the oscillator for a certain number of bars. This can be set to zero if desired.
The factor controls the chop on the various levels. A higher number will increase it.
The oscillator levels are measuring slope, price relative to the average, and a summation of percent changes between the two. Both the baseline/histogram and the levels have color coding for bullishness, bearishness, and indecision(depending on the factor.) The fast line matches the indecision color by default. This is all customizable.
There are many potential ways to trade with this indicator. From hooks back toward the trend and range line crossovers to divergence and reversals. It's important to note the current performance of the oscillator levels. Time cycles may come in handy along with other forecasting tools.
Lastly, there are optional linear regression lines plotted on the chart. They're synchronized to the lengths in the oscillator. This is an additional visual aid to provide context to the direction of the channel.
Overall the Flush Percent Range is for analyzing multiple regression models within a single price channel. No smoothing, fast averages, and specified timeframes of highs/lows. Credit to Larry Williams for the original calculation and Ken Woods for design/methodology inspiration.
ka66: Swing/Pivot Point LinesThis indicator draws swing-highs and swing-lows, also called pivot highs and lows.
A swing high is a bar which has a higher-high than its surrounding bars (to the left and the right).
A swing low is a bar which has a lower-low than its surrounding bars (to the left and the right).
A common example of a pivot is Bill Williams' Fractal, which specifies that the centre bar must have a higher high than 2 bars to its left, and 2 bars to its right for a swing high, taking into account 5 bars at a time. Similarly, for a swing low, the centre bar must have a lower low than the 2 bars to its left and right.
This indicator allows configurable adjacent bars as input. Entering 2, means it essentially picks out a Williams Fractal. But you can select 1 (say for higher timeframes), using one 1 bar to the left and right of the centre bar.
The indicator will draw Swing/Pivot High/Low as circles at the same price level as the centre bar, till the next one shows up. Drawing is offset so it starts at the centre bar (the swing bar), showing exactly where the pivot bar is.
There are 2 main uses of pivot points, in various strategies:
Market Structure: to objectively define higher-highs/lows and lower-highs/lows in Trend Analysis.
More generally, to then determine if a trend might reverse, or continue as pivot levels are broken.
Messy pivot structures easily point out ranging markets.
There are a few of these, some closed source, which I don't like, since I think people should generally know what they are trading with, and I want to make sure I understand the logic exactly.
Gabriels Trend Regularity Adaptive Moving Average Dragon This is an improved version of the trend following Williams Alligator, through the use of five Trend Regularity Adaptive Moving Averages (TRAMA) instead of three smoothed averages (SMMA). This indicator can double as a TRAMA Ribbon indicator by reducing the offset to zero. Whereas the active offset can double as a forecasting indicator for options and futures.
This indicator uses five TRAMAs, set at 8, 21, 55, 144, and 233 periods. They make up the Lips, Teeth, Jaws, Wings, and Tail of the Dragon. This indicator uses convergence-divergence relationships to build trading signals, with the Tail making the slowest turns and the Lips making the fastest turns. The Lips crossing downwards through the other lines signal a short opportunity, whereas Lips crossing upwards through other lines signal a buying opportunity. The downward cross can be referred to as the Dragon "Sleeping" , and the upward cross as the Dragon "Awakening" .
In particular, but not limited to, the Wings and Tail movements possess a Roar-like forecast effect on the market. Respectively, they can be referred to as the Dragon "Spreading its Wings" or "Swinging its Tail" .
The first three lines, stretching apart and constantly moving higher or lower, denote periods in which long or short equity positions should be managed and maintained. This can be referred to as the Dragon "Eating with a mouth wide open" . Whereas indicator lines converging into narrow bands and shifting into a horizontal position can denote a trending period coming to an end, signaling the need for profit-taking and position realignment. Conversely, a previous flat line moving can denote a new trending period starting.
This indicator can double as a Multiple TRAMAs indicator by reducing the offset to zero. As such, very interesting results can be observed when used in a moving average crossover system such as the Williams Alligator or as trailing support and resistance.
The following moving average adapts to the average of the highest high and lowest low made over a specific period, thus adapting to trend strength. The TRAMA can be used like most moving averages, with the advantage of being smoother during ranging markets because it is calculated through exponential averaging.
It is calculating, using a smoothing factor, the squared simple moving average of the number of highest highs or lowest lows previously made. Where the highest highs and lowest lows are calculated using rolling maximums and minimums. Therefore, squaring allows the moving average to penalize lower values, thus appearing stationary during ranging markets.
As with all moving averages, it is still a lagging indicator, and it can suffer whipsaws when the market moves too violently or when it consolidates in ranging conditions. Despite it working in all timeframes, it won't be as formidable in the 1–5-minute scalping timeframes due to that. I would suggest 5 to 45 minutes if you are a swing trader, or hourly, daily, and weekly if you are a long-term investor.
I hope you enjoy this indicator! It's the first indicator I made, so constructive criticism would be appreciated. Thanks!
Advanced Divergence OscillatorIntroduction to ADO
The Advanced Divergence Oscillator (ADO) is a modern tool crafted for traders in various markets like stocks, forex, or cryptocurrencies. Imagine it as a smart gadget that helps you understand the ebb and flow of market prices. Unlike standard tools, ADO provides a more nuanced view, enabling you to grasp subtle changes in market trends.
Functionality of ADO
ADO operates by observing and comparing market price movements over different timeframes. Picture a racetrack where cars are moving at various speeds. Some are racing ahead, while others are gradually picking up pace. ADO keeps track of these varying 'speeds' in market prices.
By analyzing these movements, ADO generates a smooth, flowing line – the oscillator. This line moves in a wave-like pattern, offering hints about the market's momentum and possible future trends. When the line moves up, it suggests increasing prices, and when it moves down, it hints at falling prices.
How to Use ADO
Setup: You can easily integrate ADO into your trading platform, adjusting settings like length and color to suit your preference.
Reading the Oscillator: Watch for the oscillator's movement. Rising and falling patterns can indicate potential buying or selling opportunities.
Identifying Divergences: ADO excels in spotting divergences – situations where market prices and the oscillator don't align. For instance, if prices are climbing but the oscillator is falling, it might signal a potential price drop ahead.
Brief History of the Ultimate Oscillator
The concept of oscillators in trading isn’t new. The Ultimate Oscillator, developed by Larry Williams in the 1970s, is a foundational tool in this field. Williams' innovation was to combine short, intermediate, and long-term market trends into a single oscillator. This approach offered a more comprehensive market view, helping traders make informed decisions.
The ADO is a step further in this evolution. It takes the core principles of the Ultimate Oscillator and enhances them with proper smoothing and divergence detection methods. This evolution represents the continuous effort in the trading community to refine tools for better market analysis and decision-making.
LW StructureThis easy and intuitive tool can be helpful to capture market trends.
This indicator marks the max and the min generated from the price with labels. The green labels are for the max peak and the red label for the min peak. This tool is inspired to the Larry Williams technique to easily catch the trend basing on the decreasing maximums and increasing mininums of the market structure.
Drawing inspiration from the Larry Williams approach, the LW Structure Indicator simplifies the process of recognizing trend patterns through the lens of market structure dynamics .
Fractals 5/7/9/11/13 ModifiedDescription:
The Modified Fractals Indicator is designed to help traders identify specific fractal patterns on a chart. Unlike traditional Williams Fractals, this indicator focuses on highlighting two distinct types of fractals:
- UpFractals: These fractals are identified when each preceding candle has a higher high than the one before it, and each succeeding candle has a higher high than the one following it.
- DownFractals: Conversely, DownFractals are detected when each preceding candle has a lower low than the one before it, and each succeeding candle has a lower low than the one following it.
This unique approach sets it apart from standard Fractal indicators.
Features:
1. Originality and Uniqueness: This indicator employs a distinctive algorithm to detect and display modified fractals, providing a fresh perspective on price reversals.
2. Customizable Parameters: Users can fine-tune the indicator to their trading strategy by adjusting the candle count and arrow size.
3. Easy-to-Understand Chart: The Modified Fractals Indicator is designed to provide clear and easily identifiable signals on your chart, enhancing your trading experience.
4. User-Friendly Interface: This indicator is user-friendly and can be easily integrated into your TradingView setup.
How it Works:
The Modified Fractals Indicator scans the price action on your chart and identifies specific fractal patterns based on the criteria mentioned above for both UpFractals and DownFractals.
Usage:
- Add the Modified Fractals Indicator to your TradingView chart.
- Customize the settings, including the candle count and arrow size, to align with your trading strategy.
- Observe the chart for the appearance of UpFractals and DownFractals as marked by the indicator's arrows.
- Use the signals provided by the indicator to inform your trading decisions, such as potential entry or exit points.
Please note that this Modified Fractals Indicator offers a unique approach to fractal analysis, focusing on specific price patterns that differ from traditional Williams Fractals. It provides traders with an additional tool for identifying potential trend reversals and market opportunities.
Trading ChannelTrading Channel aims to be a canvas on which to develop any strategy that the user feels comfortable with.
The greatest utility of the script lies in the fact that it plots a channel over the price action, as a support and resistance pivot, within which the price action develops.
It is a script of maximum simplicity in concept and development, but at the same time presents robust support to the price action and a quick visual aid complementary to any indicators that the user works with, feels comfortable with, and uses as a basis for their strategies.
The script includes the following features (most of them disabled by default, available for potential use without the need to add additional indicators):
Fast SMA
Medium SMA
Slow SMA (disabled)
Fast EMA (disabled)
Medium EMA (disabled)
Slow EMA (disabled)
Pivot
Pivot SMA
P Multiplier
Set of resistance and support pivots according to the studies of John L. Person (R3, R2, R1, S1, S2, S3 and midpoints) (disabled by default)
Channel for the current time period in use
Channels for extended time periods (disabled by default)
Various trend, momentum, and overbought/oversold indicating labels (note that the calculations for their representation are based on SMA's even though EMA's are visualized).
SMA's/EMA's
Both are available as both are used as basic indicators for different types of strategies. The default selection of SMA's in this case is based on the fact that the script development is largely based on the studies shared by John L. Person in the area of pivots and by Bill Williams in the area of fractals. Note also that for that same reason the various trend, momentum, and overbought/oversold indicating labels are calculated based on them.
Set of resistance and support pivots
They are included as a consultation tool especially for the higher time periods. They can be used to mark the most interesting supports/resistances and not lose sight of them while operating in lower time periods. Marking monthly, weekly, and daily pivots can be very useful. Additionally, marking S1 and R2 for bullish trends, S1 and R1 for ranges, and S2 and R1 for bearish trends can provide an even more precise framework to work on.
P Multiplier
It is set by default at 4, and is the basis for being able to consider during the use of a specific time frame, the price action with respect to higher time frames. It is the multiplier used for the generation of channels for extended time periods.
Channel for the current time period in use
It is a channel formed by the maximum and minimum closing of the last 21 periods. This value is modifiable and its adjustment depends on the asset under study. 24/7 markets show good results with this adjustment (in the case of BTC really good).
This channel represents a pivot in the form of a yellow middle line, with its support and resistance extremes on the upper green and lower red lines. The same green and red lines, referenced this time to the maximum, are added and serve as possible stop-loss marks.
Channels for extended time periods
Enabling the maximum and minimum channels for extended periods can provide a better idea of the price situation (it is recommended to disable the channel in use and enable the upper one for consultation, it provides a better vision).
Identifying labels:
Following a summary explanation for possible long entries, the same but opposite should be considered for possible short entries:
Small green arrow under candle: indicates possible upward trend (pivot above pivot SMA)
Large green arrow under candle: indicates upward trend (pivot above pivot SMA and above fast SMA)
Green triangle over candle: indicates channel breakout, possible upward momentum (represented as a fractal as its concept is the same)
Green/red arrows at the bottom of the chart: intended to confirm the validity of a signal (should doubt green indications with red lower arrow and vice versa)
Green/red dots at the bottom of the chart: red represents areas of strong resistance and green signals of strong support (with red dots, proceed with caution despite green signals, and vice versa)
Comments
It is emphasized that the basic and most useful functionality of this script is to provide a reliable base on which to develop any strategy, as a framework for working.
If the identifying labels are used, it should be taken into account that the earliest will always be the most reliable and valuable, but their confirmation will always depend on the user's strategy.
Its use in conjunction with the "Pivot Position for Trading Channel" indicator can serve as a base for the development of different strategies, by providing indication of the relative position of the price within the channel.
This script is just a consultation tool with didactic goals, it should not be used as an investment recommendation and the information provided should not be relied upon as such.
------------------------
Trading Channel pretende ser un lienzo sobre el que desarrollar cualquiera que sea la estrategia con la que el usuario se sienta más cómodo.
La mayor utilidad del script radica en que se traza sobre la acción del precio un canal, a modo de pivotes de soporte y resistencia, dentro del cual se desarrolla la acción del precio.
Se trata de un script de máxima sencillez en concepto y desarrollo, pero que a la vez presenta un soporte robusto a la acción del precio y una ayuda rápida visual complementaria a cualquieras que sean los indicadores con los que el usuario trabaje, se sienta más cómodo y utilice como base de sus estrategias.
El script incluye las siguientes funcionalidades (la mayoría desactivadas por defecto, disponibles para su potencial uso sin necesidad de añadir indicadores adicionales):
- SMA rápida
- SMA media
- SMA lenta (desactivada)
- EMA rápida (desactivada)
- EMA media (desactivada)
- EMA lenta (desactivada)
- Pivote
- SMA de pivote
- Multiplicador de P
- Conjunto de pivotes resistencia y soporte de acuerdo a los estudios de John L. Person (R3, R2, R1, S1, S2, S3 y puntos medios) (desactivados por defecto)
- Canal para el periodo temporal en uso
- Canales para periodos temporales extendidos (desactivados por defecto)
- Diversas etiquetas indicativas de cambios de tendencia, de impulso y de sobrecompra y sobreventa (nótese que los cálculos para su representación están basados en SMA's aunque se visualicen EMA's).
SMA's/EMA's
Ambas disponibles pues tanto unas como otras son utilizadas como indicadores básicos para diferentes tipos de estrategias. La selección de SMA's por defecto en este caso se basa en que las bases para desarrollo del script son en gran medida los estudios compartidos por John L. Person en el área de pivotes y de Bill Williams en el área de los fractales. Nótese también que por esa misma razón las diversas etiquetas indicativas de cambios de tendencia, impulso y sobrecompra/sobreventa se calculan en base a ellas.
Conjunto de pivotes resistencia y soporte
Se incluyen como herramienta de consulta sobre todo para los periodos temporales más altos. Pueden utilizarse para marcar los soportes/resistencias de más interés y no perderlos de vista mientras se opera en periodos de tiempo más bajos. De acuerdo a los estudios de John L. Person, marcarse los pivotes mensuales, semanales y diarios puede resultar de mucha utilidad. Adicionalmente, marcar S1 y R2 para tendencias alcistas, S1 y R1 para rangos, y S2 y R1 para tendencias bajistas puede proporcionar un marco aún más preciso sobre el que trabajar.
Multiplicador de p
Está fijado por defecto en 4, y es la base para poder considerar durante el uso de una franja temporal concreta, la acción del precio respecto a franjas temporales superiores. Es el multiplicador utilizado para la generación de los canales para periodos temporales extendidos.
Canal para el periodo temporal en uso
Se trata de un canal conformado por los cierres máximos y mínimos de los últimos 21 periodos. Este valor es modificable y su ajuste depende del activo en estudio. Mercados 24/7 muestran buenos resultados con este ajuste (en el caso de BTC realmente buenos).
Este canal representa en cierta manera un pivote en forma de línea intermedia amarilla, con sus extremos de soporte y resistencia en las líneas verdes superior y roja inferior. Se añaden las mismas líneas verdes y rojas, referenciadas esta vez a los máximos, que sirven como posibles marcas de stop-loss.
Canales para periodos temporales extendidos
Habilitar los máximos y mínimos de canales de periodos extendidos puede proporcionar una mejor idea de la situación del precio (se recomienda deshabilitar el canal en uso y habilitar el superior para consulta, proporciona una mejor visión).
Etiquetas identificativas:
A continuación explicación resumida para posibles entradas en largo, lo mismo pero de modo opuesto debería considerarse para posibles entradas en corto:
Flecha verde pequeña bajo vela: indica inicio de tendencia en alza (pivote por encima de SMA de pivote y ambos por encima de SMA rápida)
Flecha verde grande bajo vela: indica tendencia en alza (pivote por encima de SMA de pivote y ambos por encima de SMA rápida y media)
Triángulo verde sobre vela: indica rotura de canal, posible impulso al alza (representado a modo de fractal pues su concepto es el mismo)
Flechas verdes/rojas a pie de gráfico: pretenden confirmar la validez de una señal (debería dudarse de las indicaciones verdes con flecha inferior roja y viceversa)
Puntos verdes/rojos a pie de gráfico: los rojos representan áreas de fuerte resistencia y los verdes de fuerte soporte (con puntos rojos, proceder con cautela pese a señales verdes, y viceversa)
Comentarios
Se insiste en que la funcionalidad básica y de mayor utilidad de este script es proporcionar una base confiable sobre la que desarrollar cualquier estrategia, a modo de marco de trabajo.
Si se hace uso de las etiquetas identificativas, debe tenerse en cuenta que las más prematuras siempre serán las más confiables y valiosas, pero que su confirmación siempre dependerá de la estrategia por parte del usuario.
Su uso en conjunción al indicador "Pivot Position for Trading Channel" puede servir de base para el desarrollo de diferentes estrategias, al proporcionar indicación de la posición relativa del precio dentro del canal.
Este script es solo una herramienta de consulta con objetivos didácticos, no debe ser utilizado como recomendación de inversión y no se debe confiar en ella como tal.
Fourier Extrapolator of 'Caterpillar' SSA of Price [Loxx]Fourier Extrapolator of 'Caterpillar' SSA of Price is a forecasting indicator that applies Singular Spectrum Analysis to input price and then injects that transformed value into the Quinn-Fernandes Fourier Transform algorithm to generate a price forecast. The indicator plots two curves: the green/red curve indicates modeled past values and the yellow/fuchsia dotted curve indicates the future extrapolated values.
What is the Fourier Transform Extrapolator of price?
Fourier Extrapolator of Price is a multi-harmonic (or multi-tone) trigonometric model of a price series xi, i=1..n, is given by:
xi = m + Sum( a*Cos(w*i) + b*Sin(w*i), h=1..H )
Where:
xi - past price at i-th bar, total n past prices;
m - bias;
a and b - scaling coefficients of harmonics;
w - frequency of a harmonic ;
h - harmonic number;
H - total number of fitted harmonics.
Fitting this model means finding m, a, b, and w that make the modeled values to be close to real values. Finding the harmonic frequencies w is the most difficult part of fitting a trigonometric model. In the case of a Fourier series, these frequencies are set at 2*pi*h/n. But, the Fourier series extrapolation means simply repeating the n past prices into the future.
Quinn-Fernandes algorithm find sthe harmonic frequencies. It fits harmonics of the trigonometric series one by one until the specified total number of harmonics H is reached. After fitting a new harmonic , the coded algorithm computes the residue between the updated model and the real values and fits a new harmonic to the residue.
see here: A Fast Efficient Technique for the Estimation of Frequency , B. G. Quinn and J. M. Fernandes, Biometrika, Vol. 78, No. 3 (Sep., 1991), pp . 489-497 (9 pages) Published By: Oxford University Press
Fourier Transform Extrapolator of Price inputs are as follows:
npast - number of past bars, to which trigonometric series is fitted;
nharm - total number of harmonics in model;
frqtol - tolerance of frequency calculations.
What is Singular Spectrum Analysis ( SSA )?
Singular spectrum analysis ( SSA ) is a technique of time series analysis and forecasting. It combines elements of classical time series analysis, multivariate statistics, multivariate geometry, dynamical systems and signal processing. SSA aims at decomposing the original series into a sum of a small number of interpretable components such as a slowly varying trend, oscillatory components and a ‘structureless’ noise. It is based on the singular value decomposition ( SVD ) of a specific matrix constructed upon the time series. Neither a parametric model nor stationarity-type conditions have to be assumed for the time series. This makes SSA a model-free method and hence enables SSA to have a very wide range of applicability.
For our purposes here, we are only concerned with the "Caterpillar" SSA . This methodology was developed in the former Soviet Union independently (the ‘iron curtain effect’) of the mainstream SSA . The main difference between the main-stream SSA and the "Caterpillar" SSA is not in the algorithmic details but rather in the assumptions and in the emphasis in the study of SSA properties. To apply the mainstream SSA , one often needs to assume some kind of stationarity of the time series and think in terms of the "signal plus noise" model (where the noise is often assumed to be ‘red’). In the "Caterpillar" SSA , the main methodological stress is on separability (of one component of the series from another one) and neither the assumption of stationarity nor the model in the form "signal plus noise" are required.
"Caterpillar" SSA
The basic "Caterpillar" SSA algorithm for analyzing one-dimensional time series consists of:
Transformation of the one-dimensional time series to the trajectory matrix by means of a delay procedure (this gives the name to the whole technique);
Singular Value Decomposition of the trajectory matrix;
Reconstruction of the original time series based on a number of selected eigenvectors.
This decomposition initializes forecasting procedures for both the original time series and its components. The method can be naturally extended to multidimensional time series and to image processing.
The method is a powerful and useful tool of time series analysis in meteorology, hydrology, geophysics, climatology and, according to our experience, in economics, biology, physics, medicine and other sciences; that is, where short and long, one-dimensional and multidimensional, stationary and non-stationary, almost deterministic and noisy time series are to be analyzed.
"Caterpillar" SSA inputs are as follows:
lag - How much lag to introduce into the SSA algorithm, the higher this number the slower the process and smoother the signal
ncomp - Number of Computations or cycles of of the SSA algorithm; the higher the slower
ssapernorm - SSA Period Normalization
numbars =- number of past bars, to which SSA is fitted

Bar coloring
Alerts

Event Locator BasicUsable under any conditions and in all markets, the 'event locator' provides a foundational layer for any count-based trading strategy or system. This specific installment color codes events - all down events are green, up events are blue, double-marked events are red, and smooth events are gray. It also wraps the price sequence in a 3-d line landscape plot - providing a visual using lines that are event sensitive. Though events are sometimes referred to as 'fractals,' this is not a fractal tool. These marks are based on 3 candles, not 5 as is common with the Bill Williams fractal scripts. Every countable event on the chart will be marked using this tool. Really, Elliott Wave should have told you about this... (because you can't legitimately count w/o it)
//This indicator was originally a mod of the 'Williams Fractals' indicator - modified by Erek A.D., Nov. 2017
//It was rewritten from the ground up by 'Brobear' in Sept./Oct. 2018
//This code marks 'rough' AND 'smooth' EVENTS in price flow
//EVENTS are naturally created in markets when SEPARATION occurs at candle tips
//SEPARATION happens when a high is flanked by lower highs or a low is flanked by higher lows
//EVENT LOCATORS like this provide an objective foundation for counting price movement
ATR_Normalized & WPR ATR_Normalized & WPR by SkyNet33
Based in ATR_Normalized public scrypt created by @Devil1986 mixed with Classical WPR Indicator.
ATR_Normalized good to use with Williams %R indicator, to find out when price has bottomed out.
ATR has to be over 95 and Williams %R ( lenght 52 ) has to be over 95 to find out level around which one is good to buy.
WVF - OscillatorAnother attempt on making use of CM-Williams-Vix-Fix-Finds-Market-Bottoms from Chris Moody - which is arguably one of the best indicator available on pine and tradingview platform. Every time I revisit this, I get new ideas on applying this method.
I have slightly altered formula to
highest(source)-source/highest(source)
from the original formula
highest(close)-low/highest(close)
Process is simple:
Calculate WVF for OHLC values separately
Calculate momentum on each of the WVF values based on distance from moving average
Plot the candles based on OHLC momentum.
Candle color depends on whether close, open and previous close. If close is higher than open and previous close, we get green coloured candles. If close is lower than previous close and open then we get red coloured candles. In all other cases, we will have silver candles.
High/Low bands are calculated based on median of highest and lowest values of VixFix. We also plot median of close which can be used in some cases.
How to use this to find market bottom. Look for one of the below conditions:
First red candle above high band - which signals momentum of vix fix is about to fall.
First red candle above median line - can be used only if upward momentum of wvf candles are trending well.
Crossunder of wvf candles under high band.
Possible exit scenarios
Green WVF candle formed above WVF high line
Entry is taken on first red candle above median line - but, candles turned green before WVF crossing under median line - may signal our thesis is wrong and price may drop further.
Some examples.
Volatility Breakout StrategyThis is a strategy used by Larry R. Williams called Volatility Breakout.
By identifying a strong uptrend that exceeds 'a certain level' on a daily basis as a breakout signal, enter long position, take advantage of long at the the next day's open.
'a certain level (Entry Price)' is calculated by { close + 'k' * high -low }, and applied logarithmic calculation.
Stop loss level is calculated by half of the previous day's Low and Entry Price.
Strategy exit always at UTC+0.
And expressed day session with the background color.
Thanks and hope this helps you.

이건 Larry R. Williams가 사용하는 변동성 돌파 전략입니다.
특정 수준을 넘는 강한 상승세를 돌파 신호로 파악하여 매수하고, 장시간이 종료될때에 빠르게 수익을 실현하는 전략입니다.
"특정 레벨(진입가)"은 close + 'k' * high -low 로 계산되며 로그 계산을 적용했습니다.
손절 레벨은 전일 저가 및 진입 가격의 절반으로 계산됩니다.
전략은 항상 UTC+0에서 종료합니다. ( 한국 기준 오전 9시 )
그리고 배경색으로 일일세션을 표현했습니다.

Crypto Volume/Strength ComparatorHello Traders,
Here is an attempt to perform comparative analysis between top cryptos based on strength (oscillator) and volume. Methodology used here is similar to Magic Number formula described in the post : Enhanced Magic Formula for fundamental analysis . But, instead of using fundamentals, we are making use of few technicals to derive similar outcome. Usage of the available stats will not be same as Magic number since we are using technicals.
⬜ Process
▶ Get crypto exchange based on prefix of instrument being used.
▶ For the given exchange, get data for all the tickers available in input fields.
▶ Calculate Oscillator, Momentum based on price for each tickers.
▶ Calculate Oscillator, Momentum based on volume for each tickers.
▶ Calculate Volatility for each tickers.
▶ Rank Price-Oscillator, Price-Momentum, Volume-Oscillator, Volume-Momentum, Volatility for each tickers.
▶ Calculate combined rank by adding up individual ranks.
▶ Calculate movement of rankings from bar to bar
▶ Sort tickers based on rank and populate them on table. Display direction of rankings.
⬜ Components
Display components are as follows:
⬜ Settings
Settings are pretty simple and straightforward
⬜ Calculations
▶ Oscillators : High values of oscillators are considered as ideal as the process is intended towards finding trend.
▶ Momentum : Momentum is calculated on the basis of Squeeze Momentum Indicator by @LazyBear.
▶ Volatility : Volatility is calculated on the basis of Williams Vix Fix by @ChrisMoody. Here too since we are in trend following mode, lower vix fix is considered ideal.
⬜ Few Notes
Tickers will show data only if selected exchange has them. Some tickers are not available in all exchanges. In that case, it will show NAN. This is kind of unavoidable as we need to have fixed size arrays for any calculations.
Indicator works only on crypto tickers which has valid exchange.
Tickers move through the rankings in real time. Background of all stats are based on gradient from green to red.
Tickers on top may not always have better long opportunity or tickers at bottom may not always be optimal for shorting. We need to consider how long the instrument may stay in the position or how fast it is moving in opposite direction. Hence, directions of the ranking movement are also shown on the table.
robotrading ZZ-8 fractalsThis is another version of my ZZ type strategy. This script now uses Bill Williams' fractals.
Strategy
Step 1: Calculate Bill Williams' Fractals
Step 2. A line is drawn from the fractal
Step 3. Create a stop order to enter the position on the line
Trading
If the price is above the lime line, open a long position (and close a short position).
If the price is below the red line, open a short position (and close a long position).

Combo Backtest 123 Reversal & Awesome Oscillator (AO) This is combo strategies for get a cumulative signal.
First strategy
This System was created from the Book "How I Tripled My Money In The
Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
The strategy buys at market, if close price is higher than the previous close
during 2 days and the meaning of 9-days Stochastic Slow Oscillator is lower than 50.
The strategy sells at market, if close price is lower than the previous close price
during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
Second strategy
This indicator is based on Bill Williams` recommendations from his book
"New Trading Dimensions". We recommend this book to you as most useful reading.
The wisdom, technical expertise, and skillful teaching style of Williams make
it a truly revolutionary-level source. A must-have new book for stock and
commodity traders.
The 1st 2 chapters are somewhat of ramble where the author describes the
"metaphysics" of trading. Still some good ideas are offered. The book references
chaos theory, and leaves it up to the reader to believe whether "supercomputers"
were used in formulating the various trading methods (the author wants to come across
as an applied mathemetician, but he sure looks like a stock trader). There isn't any
obvious connection with Chaos Theory - despite of the weak link between the title and
content, the trading methodologies do work. Most readers think the author's systems to
be a perfect filter and trigger for a short term trading system. He states a goal of
10%/month, but when these filters & axioms are correctly combined with a good momentum
system, much more is a probable result.
There's better written & more informative books out there for less money, but this author
does have the "Holy Grail" of stock trading. A set of filters, axioms, and methods which are
the "missing link" for any trading system which is based upon conventional indicators.
This indicator plots the oscillator as a histogram where periods fit for buying are marked
as blue, and periods fit for selling as red. If the current value of AC (Awesome Oscillator)
is over the previous, the period is deemed fit for buying and the indicator is marked blue.
If the AC values is not over the previous, the period is deemed fir for selling and the indicator
is marked red.

MACandles-LinearRegression-StrategyThis is combination of multiple indicators and strategies. Mainly useful for indexes and to time the entry and exits of indexes. No stoploss used - makes it less desirable for leveraged trades or trading individual stocks.
Let us rewind and look back at some of the indicators/strategies published earlier.
1. Moving Average Candles - this is one of my favourite tool for general trend filtering. Applying supertrend on moving average candles is one of the easiest ways to find reversal in trending market without exiting positions too early. Few scripts published on this basis are:
MA Candles Supertrend
MA Candles Supertrend Strategy
2. VixFix and Linear Regression - this itself is combination of two indicators.
Williams-Vix-Fix-Finds-Market-Bottoms - by @ChrisMoody
Squeeze-Momentum-Indicator - by @LazyBear
I have combined these two indicators to derive VIX-Fix linear regression to find absolute market bottoms. More description here:
VixFixLinReg-Strategy
VixFixLinReg-Indicator
Now, in this strategy, we combine all these together.
Derive moving average candles
Derive momentum of moving average candles
Derive Linear regression on momentum
Optionally, also calculate VIX Fix and Linear regression on VixFix momentum
To find market bottom:
There are two options
1. Use when momentum of MA candles hit bottom (red) and slowly turn up (orange). In aggressiveLong mode, signals are also generated when momentum starts going positive from negative.
2. Use Vix Fix linear regression of MA candles as described in the original script of VixFixLinReg-Strategy
To find market top
Here only Ma candles momentum decreasing is used as signal. If looking for longTrades , exit signal is generated only when momentum is turning negative extreme(orange). Or else, exit signal is generated when momentum has turned neutral.
At this stage, it is very much experimental - use it with caution :)
AO-ZoneThe Zone is mention in New Trading Dimensions by Bill Williams,PhD.
The Zone is used for Entry Signal
Green Zone are painting Green when Awesome Oscillator (AO) and Accelerater/Decelerator (AC) are both increasing.
Red Zone are painting Red when Awesome Oscillator (AO) and Accelerater/Decelerator (AC) are both decreasing.
Gray Zone are painting Gray when AO and AC in difference changing
Gray Zone are indicate the indecision between bulls and bears.
Bill Williams, PhD. mention that Green Zone or Red Zone usually happen 6-8 bars Continuously.
(in my opinion, it happen lower than in intraday time frame)
The First Bar that change to be Green or Red color is the Signal Bar.
Entry Signal is the second bar in the same color as the Signal bar happen with Volume
Price go higher the high of previous Green Bar is Buy Signal. Entry Buy (Long) and place Stop at 1 tick lower the Low of previous bar.
Price go lower the Low of previous Red Bars is Sell Signal. Entry Sell (Short) and place Stop at 1 tick higher the High of previous bar.
Can Entry from 2nd bar to 5th bar.
Do not Entry if Green Bars or Red Bars completed 5 bars continuously.
This indicator have AO , AC and Zone in 1 tools and there are counter to show the number of Green bar or Red bar.
Green counter will happen when AO >0 and Green zone because AO > 0 show uptrend condition.
Red Counter will happen when AO < 0 and Red Zone because AO <0 show downtrend condition.
When we entry , we should follow the trend. So I design to non-show the counter if zone is against the trend.

[BMAX] Fractals(ENGLISH)
This is a variation of the original Fractals indicator by Bill Williams - in this version we use the concept of three candles being in a swing low when the second candle has the highest high and on a swing high when the second candle has the lowest low.
(PORTUGUÊS)
Esta é uma variação do indicador original Fractals criado por Bill Williams - nesta versão usamos o conceito de três candles sendo considerado um pivô de baixa quando o segundo candle tem a máxima mais alta e um pivô de alta quando o segundo candle tem a mínima mais baixa.
Distance From-22-Moving Averages over CMOODYwilliamsVIXFIXThis script is a mean reversion script where each of the moving averages represent the price and Chris Moody's Williams Vix Fix ZERO line represents the moving averages. There are 4 moving average types included: EMA , SMA , WMA , HMA .
You can set up to your liking by having all of the averages as any or all of the 4 options.
This script is a great way to spot bearish/bullish divergences in price action.
This script is also excellent at indicating periods of price action when volatility is extremely low - all the plots get very tight instead of spread out.
I have copy/pasted a public script by Chris Moody which is the Williams Vix Fix. This indicator shows a white circle as a "top" or "bottom" based on the current price distance off the mean (in simple terms).
Thank you Chris Moody!
Fractals | Swing Points | Highs & Lows | Custom PeriodsSimple script which marks out key swing highs & lows.
One of the only indicators I have on the chart most days
- perfect for naked charting
- quickly helps you to visually identify key areas of interest
An extension of Bill Williams fractals
- aka short term swing points
Allows you to filter for only the most prominent swing points
- you can even overlay multiple swingpoint filters in different colours (as per example chart)
The number ( Fractal Periods) is simply:
- the number of less prominent points either side of your swing high/low
- example shown on the chart
Otherwise make a fist
- look at your 5 knuckles
- swing high is your middle knuckle
- 2 lower points either side
Bill Williams Original Fractal:
Fractal Periods = 2
Your Fractal Period for Filtering:
3, 4, 5, 30, 365, etc
Allows you to find swing points down to:
Fractal Periods = 1
Simple, easy, shared to enjoy =)
Super EMA PrismThis script implements the Binary Trade Logic (BTL) algorithm to calculate two distinct scores that range from 0 to 7. One score is calculated assigning a power of 2 weight to the positive sign of 3 Phi^3 distant Moving Average (MA) slopes. The other score is calculated assigning a power of 2 weight to the sign of the difference between the price and the value of 3 Phi^3 distant Moving Average (MA).
For the first score, hereafter called as the angle score (AS), the largest MA slope positive sign receives weight 4, the middle length MA slope positive sign receives weight 2 and the shortest MA slope positive sign receives weight 1. The positive sign of an MA is defined as 1 if the slope of the MA is positive and 0, otherwise. Therefore, for MAs 305, 72 and 17, if slope(MA305) > 0, slope(MA72) < 0 and slope(MA17) > 0, then score will be 4*1 + 2*0 + 1*1 = 5. Up to my knowledge, this score was first proposed by Bo Williams and named by him as Prisma.
For the second score, hereafter called as the value score (VS), if the price > largest MA, it receives weight 4. If the price > the middle length MA, it receives weight 2 and if the price > the the shortest MA, it receives weight 1. Therefore, for MAs 305, 72 and 17, if price < MA305, price > MA72 and price > MA17, then score will be 4*0 + 2*1 + 1*1 = 3. Up to my knowledge, this score was first proposed by Bo Williams and named by him as Prisma.
Both AS and VS are calculated for Phi^3 lengths (610, 144, 34) and for Phi^3/2 lengths (305, 72, 17). The scores of the same kind calculated for each set of length are combined multiplying the Phi^3 length score by 10 and adding with with the Phi^3/2 score, therefore providing a 2 digit score ranging from 0 to 77. For instance, if we have AS(610, 144, 34) = 7 and AS(305, 72, 17) = 5, we have AS=75. At the same time, if we have VS(610, 144, 34) = 6 and VS(305, 72, 17) = 4, we have VS=64.
VS score is plotted by default in black, but it can be on white for dark themes. AS is plotted with the color of the longest MA used.
Chart background is colored according to the range of values for AS and VS, checked in the following order:
if AS >= 13 and VS <= 13 then back color = red
if AS >= 13 or VS <= 13 then back color = orange
if AS >= 64 and VS >= 64 then back color = green
if AS >= 64 or VS >= 64 then back color = blue
otherwise back color = none (white o black)
