ABCD Projection [Trendoscope®]Over the years, we have extensively explored and published numerous scripts centered around various chart patterns, including Harmonic Patterns, Reversal Patterns, Elliott Waves, and more. Our expertise in these areas has led to frequent requests for an indicator based on the ABCD pattern. Although we didn't include it as part of our Harmonic Patterns collection, the development of a dedicated ABCD Projection Indicator has always been a priority for us.
🎲 Overview of the ABCD Projection Indicator
The ABCD Projection Indicator is designed to identify and project ABCD patterns using a Zigzag-based approach. This pattern, characterized by alternating pivot highs and lows labeled as A, B, C, and D, is particularly significant in trending markets where it signifies trend continuation following deep pullbacks.
The indicator works by confirming the ABC pivots and projecting the D pivot based on the established price swings. Since ABCD patterns are most effective in trending environments, the indicator focuses on filtering patterns where the retracement from the C pivot has not compromised the trade's potential. Specifically, it ensures that the starting point (S)—where the pattern is detected—has not retraced beyond a defined threshold, preserving the opportunity to execute a trade with the goal of reaching the projected D pivot.
Additionally, the ABCD Projection Indicator considers the retracement ratio from the C pivot, which plays a crucial role in risk management. A higher retracement ratio reduces the stop distance (from pivot A to the entry point S) while increasing the distance to the target (pivot D), thereby enhancing the reward/risk ratio for trades.
🎲 Components of the ABCD Projection Indicator
The ABCD Projection Indicator comprises several key components:
A, B, C Pivots and Zigzag Wave : These elements form the foundational structure of the ABCD pattern.
S Point : This is the location where the pattern is identified, positioned a few bars away from the confirmed C pivot.
Estimated D Pivot : The D pivot is projected based on the A, B, and C price levels. The time or distance to the D pivot is influenced by the starting point S.
Mini Stats Table : Located in the top right corner, this table displays win/loss ratios and risk/reward data for both bullish and bearish scenarios.
Fibonacci Levels : Calculated from the C to D pivots, these levels are provided as a reference for additional analysis.
🎲 Indicator Settings
The settings for the ABCD Projection Indicator are minimal and intuitive, with tooltips provided to guide users through the configuration process.
Oscillator Scatterplot Analysis [Trendoscope®]In this indicator, we demonstrate how to plot oscillator behavior of oversold-overbought against price movements in the form of scatterplots and perform analysis. Scatterplots are drawn on a graph containing x and y-axis, where x represent one measure whereas y represents another. We use the library Graph to collect the data and plot it as scatterplot.
Pictorial explanation of components is defined in the chart below.
🎲 This indicator performs following tasks
Calculate and plot oscillator
Identify oversold and overbought areas based on various methods
Measure the price and bar movement from overbought to oversold and vice versa and plot them on the chart.
In our example,
The x-axis represents price movement. The plots found on the right side of the graph has positive price movements, whereas the plots found on the left side of the graph has negative price movements.
The y-axis represents the number of bars it took for reaching overbought to oversold and/or oversold to overbought. Positive bars mean we are measuring oversold to overbought, whereas negative bars are a measure of overbought to oversold.
🎲 Graph is divided into 4 equal quadrants
Quadrant 1 is the top right portion of the graph. Plots in this quadrant represent the instances where positive price movement is observed when the oscillator moved from oversold to overbought
Quadrant 2 is the top left portion of the graph. Plots in this quadrant represent the instances where negative price movement is observed when the oscillator moved from oversold to overbought.
Quadrant 3 is the bottom left portion of the chart. Plots in this quadrant represent the instances where negative price movement is observed when the oscillator moved from overbought to oversold.
Quadrant 4 is the bottom right portion of the chart. Plots in this quadrant represent the instances where positive price movement is observed when the oscillator moved from overbought to oversold.
🎲 Indicator components in Detail
Let's dive deep into the indicator.
🎯 Oscillator Selection
Select the Oscillator and define the overbought oversold conditions through input settings
Indicator - Oscillator base used for performing analysis
Length - Loopback length on which the oscillator is calculated
OB/OS Method - We use Bollinger Bands, Keltener Channel and Donchian channel to calculate dynamic overbought and oversold levels instead of static 80-10. This is also useful as other type of indicators may not be within 0-100 range.
Length and Multiplier are used for the bands for calculating Overbought/Oversold boundaries.
🎯 Define Graph Properties
Select different graph properties from the input settings that will instruct how to display the scatterplot.
Type - this can be either scatterplot or heatmap. Scatterplot will display plots with specific transparency to indicate the data, whereas heatmap will display background with different transparencies.
Plot Color - this is the color in which the scatterplot or heatmap is drawn
Plot Size - applicable mainly for scatterplot. Since the character we use for scatterplot is very tiny, the large at present looks optimal. But, based on the user's screen size, we may need to select different sizes so that it will render properly.
Rows and Columns - Number of rows and columns allocated per quadrant. This means, the total size of the chart is 2X rows and 2X columns. Data sets are divided into buckets based on the number of available rows and columns. Hence, changing this can change the appearance of the overall chart, even though they are representing the same data. Also, please note that tables can have max 10000 cells. If we increase the rows and columns by too much, we may get runtime errors.
Outliers - this is used to exclude the extreme data. 20% outlier means, the chart will ignore bottom 20% and top 20% when defining the chart boundaries. However, the extreme data is still added to the boundaries.

Flags and Pennants [Trendoscope®]🎲 An extension to Chart Patterns based on Trend Line Pairs - Flags and Pennants
After exploring Algorithmic Identification and Classification of Chart Patterns and developing Auto Chart Patterns Indicator , we now delve into extensions of these patterns, focusing on Flag and Pennant Chart Patterns. These patterns evolve from basic trend line pair-based structures, often influenced by preceding market impulses.
🎲 Identification rules for the Extension Patterns
🎯 Identify the existence of Base Chart Patterns
Before identifying the flag and pennant patterns, we first need to identify the existence of following base trend line pair based converging or parallel patterns.
Ascending Channel
Descending Channel
Rising Wedge (Contracting)
Falling Wedge (Contracting)
Converging Triangle
Descending Triangle (Contracting)
Ascending Triangle (Contracting)
🎯 Identifying Extension Patterns.
The key to pinpointing these patterns lies in spotting a strong impulsive wave – akin to a flagpole – preceding a base pattern. This setup suggests potential for an extension pattern:
A Bullish Flag emerges from a positive impulse followed by a descending channel or a falling wedge
A Bearish Flag appears after a negative impulse leading to an ascending channel or a rising wedge.
A Bullish Pennant is indicated by a positive thrust preceding a converging triangle or ascending triangle.
A Bearish Pennant follows a negative impulse and a converging or descending triangle.
🎲 Pattern Classifications and Characteristics
🎯 Bullish Flag Pattern
Characteristics of Bullish Flag Pattern are as follows
Starts with a positive impulse wave
Immediately followed by either a short descending channel or a falling wedge
Here is an example of Bullish Flag Pattern
🎯 Bearish Flag Pattern
Characteristics of Bearish Flag Pattern are as follows
Starts with a negative impulse wave
Immediately followed by either a short ascending channel or a rising wedge
Here is an example of Bearish Flag Pattern
🎯 Bullish Pennant Pattern
Characteristics of Bullish Pennant Pattern are as follows
Starts with a positive impulse wave
Immediately followed by either a converging triangle or ascending triangle pattern.
Here is an example of Bullish Pennant Pattern
🎯 Bearish Pennant Pattern
Characteristics of Bearish Pennant Pattern are as follows
Starts with a negative impulse wave
Immediately followed by either a converging triangle or a descending converging triangle pattern.
Here is an example of Bearish Pennant Pattern
🎲 Trading Extension Patterns
In a strong market trend, it's common to see temporary periods of consolidation, forming patterns that either converge or range, often counter to the ongoing trend direction. Such pauses may lay the groundwork for the continuation of the trend post-breakout. The assumption that the trend will resume shapes the underlying bias of Flag and Pennant patterns
It's important, however, not to base decisions solely on past trends. Conducting personal back testing is crucial to ascertain the most effective entry and exit strategies for these patterns. Remember, the behavior of these patterns can vary significantly with the volatility of the asset and the specific timeframe being analyzed.
Approach the interpretation of these patterns with prudence, considering that market dynamics are subject to a wide array of influencing factors that might deviate from expected outcomes. For investors and traders, it's essential to engage in thorough back testing, establishing entry points, stop-loss orders, and target goals that align with your individual trading style and risk appetite. This step is key to assessing the viability of these patterns in line with your personal trading strategies and goals.
It's fairly common to witness a breakout followed by a swift price reversal after these patterns have formed. Additionally, there's room for innovation in trading by going against the bias if the breakout occurs in the opposite direction, specially when the trend before the formation of the pattern is in against the pattern bias.
🎲 Cheat Sheet
🎲 Indicator Settings
Custom Source : Enables users to set custom OHLC - this means, the indicator can also be applied on oscillators and other indicators having OHLC values.
Zigzag Settings : Allows users to enable different zigzag base and set length and depth for each zigzag.
Scanning Settings : Pattern scanning settings set some parameters that define the pattern recognition process.
Display Settings : Determine the display of indicators including colors, lines, labels etc.
Backtest Settings : Allows users to set a predetermined back test bars so that the indicator will not time out while trying to run for all available bars.
Auto Chart Patterns [Trendoscope®]🎲 Introducing our most comprehensive automatic chart pattern recognition indicator.
Last week, we published an idea on how to algorithmically identify and classify chart patterns.
This indicator is nothing but the initial implementation of the idea. Whatever we explained in that publication that users can do manually to identify and classify the pattern, this indicator will do it for them.
🎲 Process of identifying the patterns.
The bulk of the logic is implemented as part of the library - chartpatterns . The indicator is a shell that captures the user inputs and makes use of the library to deliver the outcome.
🎯 Here is the list of steps executed to identify the patterns on the chart.
Derive multi level recursive zigzag for multiple base zigzag length and depth combinations.
For each zigzag and level, check the last 5 pivots or 6 pivots (based on the input setting) for possibility of valid trend line pairs.
If there is a valid trend line pair, then there is pattern.
🎯 Rules for identifying the valid trend line pairs
There should be at least two trend lines that does not intersect between the starting and ending pivots.
The upper trend line should touch all the pivot highs of the last 5 or 6 pivots considered for scanning the patterns
The lower trend line should touch all the pivot lows of the last 5 or 6 pivots considered for scanning the patterns.
None of the candles from starting pivot to ending pivot should fall outside the trend lines (above upper trend line and below lower trend line)
The existence of a valid trend line pair signifies the existence of pattern. What type of pattern it is, to identify that we need to go through the classification rules.
🎲 Process of classification of the patterns.
We need to gather the following information before we classify the pattern.
Direction of upper trend line - rising, falling or flat
Direction of lower trend line - rising, falling or flat
Characteristics of trend line pair - converging, expanding, parallel
🎯 Broader Classifications
Broader classification would include the following types.
🚩 Classification Based on Geometrical Shapes
This includes
Wedges - both trend lines are moving in the same direction. But, the trend lines are either converging or diverging and not parallel to each other.
Triangles - trend lines are moving in different directions. Naturally, they are either converging or diverging.
Channels - Both trend lines are moving in the same direction, and they are parallel to each other within the limits of error.
🚩 Classification Based on Pattern Direction
This includes
Ascending/Rising Patterns - No trend line is moving in the downward direction and at least one trend line is moving upwards
Descending/Falling Patterns - No trend line is moving in the upward direction, and at least one trend line is moving downwards.
Flat - Both Trend Lines are Flat
Bi-Directional - Both trend lines are moving in opposite direction and none of them is flat.
🚩 Classification Based on Formation Dynamics

🎲 Indicator Settings - Auto Chart Patterns
🎯 Zigzag Settings
Zigzag settings allow users to select the number of zigzag combinations to be used for pattern scanning, and also allows users to set zigzag length and depth combinations.
🎯 Scanning Settings
Number of Pivots - This can be either 5 or 6. Represents the number of pivots used for identification of patterns.
Error Threshold - Error threshold used for initial trend line validation.
Flat Threshold - Flat angle threshold is used to identify the slope and direction of trend lines.
Last Pivot Direction - Filters patterns based on the last pivot direction. The values can be up, down, both, or custom. When custom is selected, then the individual pattern specific last pivot direction setting is used instead of the generic one.
Verify Bar Ratio - Provides option to ignore extreme patterns where the ratios of zigzag lines are not proportionate to each other.
Avoid Overlap - When selected, the patterns that overlap with existing patterns will be ignored while scanning. Meaning, if the new pattern starting point falls between the start and end of an existing pattern, it will be ignored.

Multi-Timeframe Recursive Zigzag [Trendoscope®]🎲 Welcome to the Advanced World of Zigzag Analysis
Embark on a journey through the most comprehensive and feature-rich Zigzag implementation you’ll ever encounter. Our Multi-Timeframe Recursive Zigzag Indicator is not just another tool; it's a groundbreaking advancement in technical analysis.
🎯 Key Features
Multi Time-Frame Support - One of the rare open-source Zigzag indicators with robust multi-timeframe capabilities, this feature sets our tool apart, enabling a broader and more dynamic market analysis.
Innovative Recursive Zigzag Algorithm - At its core is our unique Recursive Zigzag Algorithm, a pioneering development that powers multiple Zigzag levels, offering an intricate view of market movements. This proprietary algorithm is the backbone of our advanced pattern recognition indicators.
Sub-Waves and Micro-Waves Analysis - Dive deeper into market trends with our Sub-Waves and Micro-Waves feature. Sub-Waves reveal the interconnectedness of various Zigzag levels, while Micro-Waves offer insight into the fundamental waves at the base level.
Enhanced Indicator Tracking - Integrate and track your custom indicators or oscillators with the zigzag, capturing their values at each Zigzag level, complete with retracement ratios. This offers a comprehensive view of market dynamics.
Curved Zigzag Visualization - Experience a new way of visualizing market movements with our Curved Zigzag Display, employing Pine Script’s polyline feature for a more intuitive and visually appealing representation.
Built-in Customizable Alerts - Stay ahead with built-in alerts that can be customized via user input settings.
🎯 Practical Applications
Our Zigzag Indicator is designed with an understanding of its inherent nature - the last unconfirmed pivot that consistently repaints. This characteristic, while by design, directs its usage more towards pattern recognition rather than direct identification of market tops and bottoms. Here's how you can leverage the Zigzag Indicator:
Harmonic Patterns - Ideal for those familiar with harmonic patterns, this tool simplifies the manual spotting of complex XABCD, ABC, and ABCD patterns on charts.
Chart Patterns - Effortlessly identify patterns like Double/Triple Taps, Head and Shoulders, Inverse Head and Shoulders, and Cup and Handle patterns with enhanced clarity. Navigate through challenging patterns such as Triangles, Wedges, Flags, and Price Channels, where the Zigzag Indicator adds a layer of precision to your breakout strategy.
Elliott Wave Components - The indicator's detailed pivot highlighting aids in identifying key Elliott Wave components, enhancing your wave analysis and decision-making process.
🎲 Deep Dive into Indicator Features
Join us as we explore the intricate features of our indicator in more detail.
🎯 Multi-Timeframe Capability
Our indicator comes equipped with an input option for selecting the desired resolution. This unique feature allows users to view higher timeframe Zigzag patterns directly on their lower timeframe charts.
🎯 Recursive Multi Level Zigzag
Our advanced recursive approach creates multi-level Zigzags from lower-level data. For instance, the level 0 Zigzag forms the base, calculated from specified length and depth parameters, while level 1 Zigzag is derived using level 0 as its foundation, and so forth.
The indicator not only displays multiple Zigzag levels but also offers settings to emphasize specific levels for more detailed analysis.
🎯 Sub-Components and Micro-Components of Zigzag Wave
Sub-components within a Zigzag wave consist of the previous level's Zigzag pivots. Meanwhile, the micro-components are composed of the base level (Level 0) Zigzag pivots encapsulated within the wave.
🎯 Curved Zigzag
Experience a new perspective with our curved Zigzag display. This innovative feature utilizes the polyline curved option to automatically generate sinusoidal waves based on multiple points.
🎯 Indicator Tracking
Default indicators such as RSI, MFI, and OBV are included, alongside the ability to track one external indicator at each Zigzag pivot.
🎯 Customizable Alerts
Our indicator employs the `alert()` function for alert creation. While this means the absence of a customization text box in the alert settings, we've included a custom text area for users to create their own alert templates.
Template placeholders include:
{alertType} - type of alert. Either Confirmed Pivot Update or Last Pivot Update. Depends on the alert type selected in the inputs.
When Last Pivot Update type is selected, the alerts are triggered whenever there is a new Zigzag Pivot. This may also be a repaint of last unconfirmed pivot.
When Confirmed Pivot Update type is selected, the alerts are triggered only when a pivot becomes a confirmed pivot.
{level} - Zigzag level on which the alert is triggered.
{pivot} - Details of the last pivot or confirmed pivot including price, ratio, indicator values and ratios, subcomponent and micro-component pivots.
🎲 User Settings Overview
🎯 Zigzag and Generic Settings
This involves some generic zigzag calculation settings such as length, depth, and timeframe. And few display options such as theme, Highlight Level and Curved Zigzag. By default, zigzag calculation is done based on the latest real time bar. An option is provided to disable this and use only confirmed bars for the calculation.
Indicator Settings
Allows users to track one or more oscillators or volume indicators. Option to add any indicator via external input is provided.
🎯 Alert Settings
Has input fields required to select and customize alerts.

The Zigzag Tails Indicator, a groundbreaking tool from Trendoscope, redefines technical analysis by seamlessly integrating anchored VWAPs (Volume Weighted Average Prices) and Average Price calculations with Zigzag pivot points. This advanced indicator recalculates Average Price or VWAP from one Zigzag pivot to the next, offering unparalleled insights into market movements.
🎯 Innovative Design
Each Zigzag pivot can feature up to three distinct tails, corresponding to the high, low, and close prices of each candle. Users have the flexibility to select between Average Price and VWAP for display on their charts. By default, the indicator plots all three tails, but individual tail visibility is customizable via the settings panel.
Average Price Mode: When selected, tails depict the average price across a specified number of bars.
VWAP Mode: In this mode, tails represent the VWAP, calculated for a given price over a set number of bars.
🎯 Dynamic Dotted Tail
The Zigzag Tails Indicator features dotted tails that extend from the last Zigzag pivot to the current bar. These dotted tails dynamically adapt to market changes and are subject to repainting with the emergence of new Zigzag pivots.
When repainting is enabled, the dotted tails originate from the last unconfirmed Zigzag pivot, extending to the current bar. This setting offers a more immediate, albeit tentative, visual representation of market trends.
With repainting disabled, the dotted tails will be anchored from the last confirmed Zigzag pivot to the current bar, providing a more stable but slightly delayed market analysis.
Irrespective of the repaint option, the dotted dynamic tails is always expected to repaint.
🎯 Practical Applications
The Zigzag Tails Indicator provides more accurate support and resistance levels than traditional VWAP, rolling VWAP, or moving averages. Its precision makes it an invaluable tool for identifying trends, as well as potential trend continuations or reversals.
🛠 Indicator Settings
Zigzag Configuration:
Zigzag Length determines the loopback length for the foundational Zigzag calculation.
Number of Bars represent the calculation distance. This limitation is added to avoid runtime errors on lower timeframes. The calculations run through lots of loops. Hence, if it is run across too many bars, we may get timeout issues.
Repaint: Activating this will also display the last, unconfirmed Zigzag pivot. Since the last pivot is inherently tentative, it may repaint with the arrival of new bars. A pivot is confirmed only when a subsequent unconfirmed pivot emerges on the chart.
Tail Configuration
Tail Type: Choose between average and VWAP for the tail calculation. The average option plots a simple average, while the VWAP option calculates an anchored VWAP from pivot to pivot.
Display Options: Tailored display options for High, Low, Close prices, with customizable colors for each tail type.

Divergence Indicator [Trendoscope®]🎲 New Divergence Indicator by Trendoscope
Our latest Divergence Indicator revolutionizes the way traders identify market trends and potential reversals. Built upon the robust foundation of the Zigzag Trend Divergence Detector and inline with our recent implementation of the Divergence Goggles indicator, this tool is designed to be intuitive yet powerful, making it an essential addition to any trader's toolkit.
We received several queries on extending the Divergence Goggles to last N bars instead of using an interactive widget. Though it is possible, we thought the better approach is to enable the indicator to use any oscillator and trend indicator in order to define the divergence.
🎯 Key Features
Flexible Oscillator Integration : Choose from a wide range of built-in oscillators or import your own, including options like the innovative Multiband Oscillator. This versatility extends to using volume indicators like OBV for divergence calculations, broadening the scope of analysis.
Trend Identification Versatility : Utilize built-in methods like Zigzag and MA Difference, or integrate external trend indicators. Our system adapts to various methods, ensuring you have the right tools for precise trend identification.
Customizable Zigzag Sensitivity : Adjust the Zigzag based on your chosen oscillator's sensitivity to ensure divergence lines are accurate and visually coherent.
Repainting vs. Delayed Signals : Tailor the indicator to your strategy by choosing between immediate repainting signals and slightly delayed but more stable signals.
🎯 Understanding Divergence: Key Rules
Bullish Divergence
Happens only in downtrend
Observed on Pivot Lows
Price makes lower low whereas oscillator makes higher low, indicating weakness and possible reversal
Bearish Divergence
Happens only in uptrend
Observed on Pivot Highs
Price makes higher high whereas oscillator makes lower high, indicating weakness and possible reversal
Bullish Hidden Divergence
Happens only in uptrend
Observed on Pivot Lows
Price makes higher low, whereas indicator makes lower low due to price consolidation. In bullish trend, this is considered as bullish as the price gets a breather and get ready to surge further.
Bearish Hidden Divergence
Happens only in downtrend
Observed on Pivot Highs
Price makes lower high whereas oscillator makes higher high due to price consolidation. In bearish trend, this is considered as bearish as the price gets a breather and get ready to fall further.

🎲 Using the Divergence Indicator: A Step-by-Step Guide
🎯 Step 1 - Selecting the Oscillator
Customize your analysis by choosing from a variety of oscillators or importing your preferred one. Options are available to select a range of built-in oscillators and the loopback length. However, if the oscillator that user want to use is not in the list, they can simply load the oscillator from the indicator library and use it as an external signal.
In our current example, we are using a custom oscillator called - Multiband Oscillator
This also means, the indicator option is not limited to oscillators. Users can even make use of volume indicators such as OBV for the calculation of divergence.
🎯 Step 2 - Choosing the Trend Identification Method
Select from our built-in methods or integrate an external indicator to accurately identify market trends. Trend is one of the key parameters of divergence type identification. Trend can be identified mathematically by various methods. Some of them are as simple as above or below 200 moving average and some can follow trend based indicators such as supertrend and others can be very complex.
To cater for a wider audience, here too we have provided the option to use an external trend indicator. The simple condition for the external trend indicator is that it should return positive value for uptrend and negative value for downtrend.
Other than that, we also have 2 built in trend identification methods.
Zigzag - The trend is defined by the starting pivot of divergence line. If the starting pivot is Higher High or Higher Low, then it is considered uptrend. And if the starting pivot is either Lower Low or Lower High, then we consider it as downtrend.
MA Difference - In this case, the difference between the moving average of pivots joining the divergence line will determine the trend. It is considered uptrend if the moving average increased from starting pivot to ending pivot of the divergence line, and it is considered downtrend if the moving average decreased from starting pivot to the ending pivot of the divergence line.
🎯 Step 3 - Adjusting Zigzag Sensitivity
Fine-tune the Zigzag to match the oscillator's sensitivity, ensuring divergence lines are accurate and visually coherent.
🎯 Step 4 - Managing Repainting
Understand the implications of repainting in the last pivot of the Zigzag and choose between immediate or delayed signals based on your trading strategy. The last pivot of the zigzag repaint by design. This is not necessarily a bad thing. Users can just choose not to use the last pivot, but instead use the last but one for all the calculations. But, this also means, the signals will be delayed.
Indicator provides option to use repainting signal vs delayed signal. If you select the repaint option, the signals are shown immediately as and when they occur. But, there is a possibility that these signals change when the new price candles change zigzag pivot.
If you chose not to select the repaint option, then the divergence signals may lag by a few bars.
