Divergence BacktesterThere is n number of possible ways in which we can backtest divergence and this is just a start :)
In this script, we are trying to count how many times the pivots made HH, HL, LH, LL after a particular divergence state.
An example of using data is as below:
The script keeps track of each pivot sentiment and resulting next pivot state. As mentioned in the chart snapshot, we can look at two of the previous pivot states and collect stats on how each of these state impacted price action.
As mentioned before, this is just tip of iceberg. Further combinations for which we can do backtest are:
1. m X n combinations of last pivot and last to last pivot divergence state
2. divergence combined with double divergence state.
Only issue to explore further is lack of space on the chart as tables can take up huge space.
PS: As you can see based on historical stats, probability of divergence impacting the change of trend is very low in most cases.

RSI Swing Indicator v2The 2nd version of this indicator came quick :)
As the previous one, it draws swings on the candlesticks, based on price action and RSI.
Also in the labels you can see if the current swing is higher or lower to the previous one.
HH stands for Higher High
LL stands for Lower Low
LH means Lower High
HL means Higher low
THIS IS NOT A STRATEGY, this is for TREND analysis.
Please stop asking if it "redraws", because it doesn't matter.
The labels are not SELL or BUY signals
zigzag all timeThe indicator is applicable across all timeframes, meaning it can be used for short-term (e.g., minutes, hours) or long-term (e.g., days, weeks, months) trading strategies. This ensures that the analysis is versatile and adaptable to different trading styles.

Recursive Reversal Chart Patterns [Trendoscope]Caution: This algorithm is very heavy and bound to cause timeouts. If that happens, there are few settings you can change to reduce the load. (Will explain them in the description below)
🎲 Recursive Reversal Chart Patterns Indicator
Welcome to another exploration of Zigzag and Pattern ecosystem components. Previously we derived Pitchfork and Recursive Zigzag indicators. This indicator is designed to scan and highlight few popular "Reversal Chart Patterns". Similar to other indicators in the ecosystem, this too is built on recursive zigzags.
Double Taps
Triple Taps
Cup and Handles
Head and Shoulders
Indicator however names the patterns separately for bullish and bearish formations. So, the actual names you see on the screen are
Double Top
Double Bottom
Triple Top
Triple Bottom
Cup and Handle
Inverted Cup and Handle
Head and Shoulders
Inverse Head and Shoulders
Here is a snapshot on how each category of patterns look on the chart.
🎲 Architecture
Many of you may be cursing me for publishing too many libraries. But, these are all preparations for something big. Like other indicators in the Zigzag and Patterns Ecosystem, this too uses a bunch of libraries.
🎯Major direct dependencies
ZigzagTypes
ZigzagMethods
ReversalChartPatternLibrary
🎯Indirect dependencies
DrawingTypes
DrawingMethods
🎯Minor dependencies
Utils
TradeTracker
🎲 Indicator Settings
🎯Generic and Zigzag Settings.
Note: In case of timeout, please decrease the value of depth parameter
🎯Pattern Selection
Having all the patterns selected on chart may also cause timeouts and will make the chart look messy. It is better to limit one or two patterns on the chart to have clear picture.
🎯Scanner Settings
🎯Indicators.
These are options to use indicators as secondary confirmation to calculate divergence. If selected, the patterns are shown only if the divergence data is inline. Option also available to plugin external indicator. These calculations are not straightforward and not easy to measure by manual inspection. This feature at present is purely experimental.
Have a go and let me know how you feel :)
Auto Fib Speed Resistance Fans by DGTFibonacci Speed and Resistance Fan is an analytical drawing tool used to indicate the support and resistance levels of an existing trend and the price level at which possible changes in the trend may occur.
A Fibonacci Speed Resistance Fan consists of a trend line drawn between two extreme points - a trough and opposing peak or a peak and opposing trough - on which a set of sequential speed resistance lines are drawn above (which represents time) and below (which represents price). These lines are drawn based on time/price percentages of the distance between the beginning and the end of the trend line.
Speed resistance lines not only help to measure trend corrections but also measure the speed of a trend (the rate at which a trendline ascends or descends)
Traders can use the lines of the Fibonacci Speed and Resistance Fan to predict key points of resistance or support, at which they might expect price trends to reverse. Once a trader identifies patterns within a chart, they can use those patterns to predict future price movements and future levels of support and resistance. Traders use the predictions to time their trades. Key support and resistance levels tend to occur frequently at the 61.8-percent level on both uptrends and downtrends.
Please check for further details in the education post that I will share shortly after this publication :
Nobody appears to know whether Fibonacci tools work because markets exhibit some form of natural pattern or because many investors use Fibonacci ratios to predict price movements, making them a self-fulfilling prophecy.
█ Study OPTIONS
Auto Fibonacci Speed and Resistance Fan , the main aim of the study
- Pivot threshold can be adjusted via “Deviation” and “Depth” input options
- Historical Fans option will allow plotting of Speed and Resistance Fans on previous pivot high/lows
- Ability to set ALERTs for the Speed and Resistance Levels
- Price Grid Lines if extended it will result with Fib Retracement levels
- All lines, line levels are customizable, default values are set exactly to the same with the available Fib Speed and Resistance Fan drawing tool
Zig Zag – Derived from build-in Auto Fib Retracement with some customization options.

indicatorLow : Array of indicators values calculated based on low price of OHLC
numberOfPivots : Number of pivots to be returned
Returns: pivotMatrix Matrix containing zigzag pivots, pivot bars, direction, ratio, and indicators added via indicatorHigh/indicatorLow
newZG is true if a new pivot is added to array
doubleZG is true if last calculation returned two new pivots (Happens on extreme price change)
draw(length, ohlc, indicatorLabels, indicatorHigh, indicatorLow, numberOfPivots, lineColor, lineWidth, lineStyle, showHighLow, showRatios, showIndicators) draws zigzag and related information
Parameters:
length : is zigzag length
ohlc : array of OHLC values to be used for zigzag calculation
indicatorLabels : Array of name of indicators passed
indicatorHigh : Array of indicator values calculated based on high price of OHLC

Buy Sell Magic Rework📌 Purpose
This script is a reworked version of the Parabolic SAR strategy, with an optional ZigZag filter to confirm reversal points.
It helps traders identify potential trend reversals with reduced noise compared to the standard SAR.
🧠 How It Works
1. Parabolic SAR Flip Signals
Buy Signal: Triggered when SAR flips from above price to below price.
Sell Signal: Triggered when SAR flips from below price to above price.
(Default SAR parameters: Start = 0.02, Increment = 0.02, Max = 0.2)
2. ZigZag Filter (Optional)
When Use ZigZag Filter = true:
The script confirms reversals only at significant pivots (swing highs/lows) detected by the ZigZag algorithm over the selected ZigZag Period (default = 14 bars).
Buy Signal: Appears only when a new pivot low is detected.
Sell Signal: Appears only when a new pivot high is detected.
3. Trade-Off
Without ZigZag: More signals, more noise.
With ZigZag: Fewer signals, but stronger confirmation and reduced false entries.
📈 How to Use
Signals appear as green arrows for buy and red arrows for sell.
Works well for:
Trend reversal detection.
Swing trading confirmation.
Filtering entries for other systems.
Recommended Timeframes: 15m, 1h, 4h.
Markets: Forex, Crypto, Stocks.
⚙️ Inputs
ZigZag Period (bars for pivot detection)
SAR Start / Increment / Max (SAR parameters)
Use ZigZag Filter (toggle for confirmation)

Fibonacci Retracement/ExtensionThis Pine Script code implements Fibonacci retracement and extension levels based on a ZigZag pattern. Below is a breakdown of its functionality:
Overview
The script calculates Fibonacci retracement and extension levels by identifying swing highs and swing lows using the ZigZag algorithm. It then plots these levels on the chart for trend analysis.
1. ZigZag Length Input
Defines the ZigZag length, which determines the sensitivity of peak and trough identification.
2. Fibonacci Retracement Calculation
Computes Fibonacci retracement levels using swing highs and lows.
Uses pre-defined Fibonacci ratios (0.236, 0.382, 0.5, 0.618, 0.786, 1.0).
Adjusts line positions dynamically as the trend evolves.
3. Fibonacci Extension Calculation
Identifies Fibonacci extension levels for future price targets.
Uses previous ZigZag patterns to estimate potential price movements.
4. Trend and Fibonacci Configuration
Allows the user to configure Fibonacci trend analysis.
TrendSw: Sets the trend direction (1 = Bullish, -1 = Bearish, 0 = None).
ZigZagleg: Determines the countback value for retracement calculations.
---Advanced Harmonic Pattern Scanner v5Summary of the Script:
All Patterns Covered: The script includes all major harmonic patterns: Butterfly, Gartley, Crab, Bat, Cypher, and Three Drives. Both bullish and bearish versions are detected.
ZigZag Swings: The zigzag logic helps find swing points (X, A, B, C, D) which are essential for forming these patterns. You can adjust the zigzagDepth parameter to fine-tune how sensitive the pattern detection is to price swings.
Fibonacci Levels: Each pattern uses specific Fibonacci retracement or extension levels to identify potential patterns, and the script compares price movements to these ratios.
Visual Aid: It uses plotshape() to display detected patterns on the chart and optional line.new() functions to connect the swing points for a better visual representation of the patterns.
How to Customize:
Timeframe: You can run this script on different timeframes by changing the chart on TradingView (1 min, 1 hour, 1 day, etc.).
ZigZag Sensitivity: Adjust the zigzagDepth to refine how frequently swing points are detected. Larger numbers will reduce sensitivity and show fewer but more pronounced patterns.
Pattern Refinement: Modify Fibonacci levels to experiment with custom harmonic patterns or adjust thresholds for the existing ones.
This code is an advanced version and scans the market comprehensively for all major harmonic patterns. Let me know if you need further modifications or explanations!
Advanced Pattern Detector**Script Overview**
**Indicator Name:** Advanced Pattern Detector
**Pine Script Version:** v5
**Indicator Type:** Overlaid on the chart (overlay=true)
**Main Features:**
- Detection and visualization of various technical patterns.
- Generation of BUY and SELL signals based on detected patterns.
- Display of Fibonacci levels to identify potential support and resistance levels.
- Ability to enable or disable each pattern through the indicator settings.
---
**Indicator Settings**
**Switches to Enable/Disable Patterns**
At the top of the indicator, there are parameters that allow the user to select which patterns will be displayed on the chart:
- Three Drives
- Rounding Top
- Rounding Bottom
- ZigZag Pattern
- Inverse Head and Shoulders
- Fibonacci Retracement
**Parameters for ZigZag**
Settings are also available for the ZigZag pattern, such as the depth of peak and trough detection, allowing the user to adjust the indicator's sensitivity to price changes.
---
**Pattern Detection**
Each pattern is implemented with its own logic, which checks specific conditions on the current bar (candle). Below are the main patterns:
1. **Three Drives**
- **Description:** This pattern consists of three consecutive price movements in one direction (up or down). It can signal the continuation of the current trend or its reversal.
- **How It Works:**
- **Upward Drive:** The indicator checks that the closing price of each subsequent candle is higher than the previous one for three bars.
- **Downward Drive:** The indicator checks that the closing price of each subsequent candle is lower than the previous one for three bars.
2. **Rounding Top**
- **Description:** A pattern representing a smooth decrease in maximum prices over several bars, which may indicate a potential downward trend reversal.
- **How It Works:**
- The indicator checks that the maximum prices of the last five bars are gradually decreasing, and the current bar shows a decrease in the maximum price.
3. **Rounding Bottom**
- **Description:** A pattern characterized by a smooth increase in minimum prices over several bars, signaling a possible upward trend reversal.
- **How It Works:**
- The indicator checks that the minimum prices of the last five bars are gradually increasing, and the current bar shows an increase in the minimum price.
4. **ZigZag Pattern**
- **Description:** Used to identify corrective movements on the chart. The pattern shows peak and trough points connected by lines, helping to visualize the main price movement.
- **How It Works:**
- The indicator uses a function to determine local maxima and minima based on the specified depth.
- Detected peaks and troughs are connected by lines to create a visual zigzag structure.
5. **Inverse Head and Shoulders**
- **Description:** An inverted head and shoulders formation signals a possible reversal of a downward trend to an upward one.
- **How It Works:**
- The indicator looks for three local minima: the left shoulder, the head (the lowest minimum), and the right shoulder.
- It checks that the left and right shoulders are approximately at the same level and below the head.
6. **Fibonacci Retracement Levels**
- **Description:** Automatically builds key Fibonacci levels based on the maximum and minimum prices over the last 50 bars. These levels are often used as potential support and resistance levels.
- **How It Works:**
- Daily, the minimum and maximum prices over the last 50 bars are calculated.
- Based on these values, Fibonacci levels are drawn: 100%, 23.6%, 38.2%, 50%, 61.8%, and 0%.
- Old levels are removed when a new day begins to keep the chart clean and up-to-date.
---
**Generation of Buy and Sell Signals**
The indicator combines the results of detected patterns to generate trading signals:
- **Buy Signals (BUY):**
- Rounding Bottom
- Three Drives Up
- Inverse Head and Shoulders
- ZigZag Low
- **Sell Signals (SELL):**
- Rounding Top
- Three Drives Down
- Inverse Head and Shoulders
- ZigZag High
**How It Works:**
- If one or more buy conditions are met, a "BUY" label is displayed below the corresponding bar on the chart.
- If one or more sell conditions are met, a "SELL" label is displayed above the corresponding bar on the chart.
---
**Visualization of Patterns on the Chart**
Each detected pattern is visualized using various graphical elements, allowing traders to easily identify them on the chart:
- **Three Drives Up:** Green upward triangle below the bar.
- **Three Drives Down:** Red downward triangle above the bar.
- **Rounding Top:** Orange "RT" label above the bar.
- **Rounding Bottom:** Blue "RB" label below the bar.
- **Inverse Head and Shoulders:** Turquoise "iH&S" label below the bar.
- **ZigZag High/Low:** Purple circles at the peaks and troughs of the zigzag.
---
**Displaying Fibonacci Levels**
Fibonacci levels are displayed as horizontal lines on the chart with corresponding labels. These levels help traders determine potential entry and exit points, as well as support and resistance levels.
---
**Drawing ZigZag Lines**
ZigZag lines connect the detected peaks and troughs, visualizing corrective movements. To avoid cluttering the chart, the number of lines is limited, and old lines are automatically removed as new ones are added.
Divergence-Support/Resistance - Widget [HeWhoMustNotBeNamed]Unique live widget which provides information about support and resistance along with distance to immediate levels.
⬜ Custom Candle Source
Three options of candles available
▶ Regular OHLC candles
▶ Heikin-Ashi candles ( Taken leaf out of @Bjorgum's book - but, still could not do it as good as him :) )
▶ Moving average candles
⬜ Multiple zigzags and choice of oscillator
Like any other zigzag based indicator, I prefer using 4 zigzag levels.
And select oscillator of your choice to identify divergence. Oscillator lengths are automatically calculated based on zigzag lengths. You can also chose external oscillator.
⬜ Support and resistance widget settings
▶ Max S/R per zigzag - this is the number of last S/R levels recorded for each zigzag
▶ Max S/R for stats - even though there can be many number of S/R levels, we cannot show all of them in the widget due to space constraint. Hence, this is set to minimal value of 3. Can be changed via this input.
▶ Max S/R for Alerts - When sending stats through alerts, users can decide how many immediate S/R levels to be sent in them.
▶ Alert Choices - Can chose to get alerts when new S/R levels formed and also when existing S/R levels broken.
Personally think it is a very handy widget to have!!
Auto Fib Channels by DGTThe Fibonacci Channel is a technical analysis tool that is used to estimate support and resistance levels based on the Fibonacci numbers. It is a variation of the Fibonacci retracement tool, except with the channel the lines run diagonally rather than horizontally.
This study will automatically place the channels where the levels indicate future areas of support and resistance
For further details please refer to education post
Nobody appears to know whether Fibonacci tools work because markets exhibit some form of natural pattern or because many investors use Fibonacci ratios to predict price movements, making them a self-fulfilling prophecy.
█ Study OPTIONS
Auto Fibonacci Channels , the main aim of the study
- Pivot threshold can be adjusted via “Deviation” and “Depth” input options
- Historical Channels / Retracements option will allow plotting of Channels on previous pivot high/lows
- Ability to set ALERTs for the Channel Levels
