Master Supertrend [Trendoscope]Are you a fan of supertrend? Me too!! Here is a supertrend indicator which provides multiple variation options to chose from.
🎲 Introduction
Supertrend is a popular technical indicator used by traders to identify potential trend reversals and determine entry and exit points in financial markets. It is a trend-following indicator that combines price and volatility to generate its signals. Generally supertrend is calculated based on ATR and multiplier value which is used for calculation of stops. In these adaptions, we look to provide few variations to classical methods.
🎲 Variations
Following variations are provided in the form of settings.
🎯 Range Type
Instead of ATR, different types of ranges can be used for stop calculation. Here is the complete list used in the script.
Plus/Minus Range - Calculates plus range and minus range for each candle and uses them for different sides of stop calculation
Ladder ATR - Based on the existing concept of Ladder ATR defined in Supertrend-Ladder-ATR
True Range - True range derived from standard function ta.tr
Standard Deviation - Standard deviation of close prices
🎯 Applied Calculation
In standard ATR, rma of TR is used for calculations. But, the application calculation provides option to users to use different mechanisms. It can be a type of moving average or few other types of calculations.
Available values are
sma
ema
hma
rma
wma
high
median
medianHigh (Highest of the last N medians)
medianLow (Lowest of the last N medians)
🎯 Other options
Few other options provided are
Use Close Price - If selected stops are calculated based on the close price instead of high/low prices
Wait for Close If selected, change of supertrend direction is calculated based on close price instead of high/low prices
Diminishing Stop Distance - When selected, stop distance for the trend direction can only reduce and cannot increase. This option is useful for keeping the tight stops on strong trends.
🎯 Plus Minus Range
One of the range type used is Plus/Minus Range. What it means and how are these ranges calculated? Let's have a look.
Plus Range is an upward movement of a candle from its last price or open price whichever is lower.
Minus Range is a downward movement of a candle from its last price or open price whichever is higher.
This divides True Range into two separate range for positive and negative side.
Here are the simple settings in nutshell which reflects the same.

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

ReversalChartPatternLibrary
🎯Indirect dependencies

🎯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 :)

Session Filter [Trendoscope]🎲 Session Filter: A Customisable Trading Indicator for Defining Preferred Trade Sessions
Session Filter is a simple trading indicator that enables traders to define their preferred trading sessions and optimise their approach based on individual preferences. By providing a range of flexible customisation options, Session Filter can help traders reduce risk, increase accuracy, by helping them to adhere to their trading sessions. Features include
🎯 Customisable Trading Sessions
One of the key features of Session Filter is the ability to select from four different trading sessions. These sessions are designed to be flexible, making it easy to tailor your approach to specific markets, assets, and trading styles. By selecting the sessions that are most relevant to your strategy, you can reduce the risk of making trades during less favourable market conditions.
For example, if you prefer to trade during the Asian session, you can set the session times to "Asian Session" in input settings. This will highlight the specific times when the Asian markets are open, allowing you to focus your trading activity during these periods. By doing so, you can avoid trading during times when the market is less active or more volatile.
🎯 Customisable Timezone and Days of the Week:
In addition to customisable trading sessions, Session Filter also allows users to select a timezone and specific days of the week. This ensures that the displayed trading zones and signals are aligned with your local time, and that you can tailor your approach to your preferred schedule. This is particularly useful for traders who have other commitments, or who prefer to focus on specific markets or assets on certain days.
For example, if you are based in New York and prefer to trade during the European session, you can select the "European Session" option in Session Filter and adjust the timezone to reflect your local time. You can also select specific days of the week when you prefer to trade during the European session, such as Tuesday through Thursday. This allows you to optimize your approach based on your personal preferences and schedule.
🎯 Easy Visual Interpretation:
Session Filter uses green and red overlays on the chart to indicate the trading zones, making it easy for users to visually identify their trading sessions
For example, when a green overlay is displayed on the chart, this indicates that the market is within the selected trading session and that it may be a good time to start trade. Conversely, when a red overlay is displayed, this indicates that the market is outside of the selected trading session and that it may be a good time close all trading. By providing this visual feedback, Session Filter helps traders stay focused and disciplined, and avoid making impulsive trading decisions.
🎯Force Exit Signal for Risk Management:
Session Filter also offers the ability to generate a force exit signal when not in any of the selected sessions. This can be used in conjunction with alerts to exit all trades outsize session zone.
For example, if you are using Session Filter to trade during the European session, but the market is particularly volatile during a specific day, the force exit signal will be generated to indicate that it may be a good time to exit your trade. This helps you avoid potential losses and stay disciplined during periods of market turbulence.
🎯External Signal Plots:
In addition to the chart overlays, Session Filter also plots signals on the data window that can be used as external inputs in other indicators and strategies. This feature allows traders to incorporate the signals generated by Session Filter into their existing trading systems and this can be used as additional filters on an existing strategy or methodology.
🎯Alerts using Alert Conditions
Alerts are provided for start and end of session so that users can make use of it to set auto turn on or off their bots.
Settings are pretty simple and are explained here.

Angled Volume Profile [Trendoscope]Volume profile is useful tool to understand the demand and supply zones on horizontal level. But, what if you want to measure the volume levels over trend line? In trending markets, the feature to measure volume over angled levels can be very useful for traders who use these measures. Here is an attempt to provide such tool.
🎲 How to use
🎯 Interactive input for selecting starting point and angle.
Upon loading the script, you will be prompted to select
Start time and price - this is a point which you can select by moving the maroon highlighted label.
End price - though this is shown as maroon bullet, this is price only input. Hence, when you click on the bullet, a horizontal line will appear. Users can move the line to use different End price.
Start and End price are used for identifying the angle at which volume profile need to be calculated. Whereas start time is used as starting time of the volume profile. Last bar of the chart is considered as ending bar.
🎯 Other settings.
From settings, users can select the colour of volume profile and style. Step multiplier defines the distance at which the profile lines needs to be drawn. Higher multiplier leads to less dense profile lines whereas lower multiplier leads to higher density of profile lines.
🎲 Limitations
🎯 Max 500 lines
Pinescript only allows max 500 lines on an indicator. Due to this, if we set very low multiplier - this can lead to more than 500 profile lines. Due to this some lines can get removed.
On the contrary, if multiplier is too high, then you will see very few lines which may not be meaningful.
Hence, it is important to select optimal multiplier based on your timeframe
🎯 No updates on new bar
Since the profile can spawn many bars, it is not possible to recalculate the whole volume profile when price creates new bars. Hence, there will not be visual update when new bars are created. But, to update the chart, users only need to make another movement of Start or ending point on interactive input.

Recursive Zigzag [Trendoscope]Here is an another outcome of Object Oriented Zigzag and Pattern Ecosystem of Libraries.
We already have another implementation of recursive zigzag which makes use of earlier library rzigzag . Here in this example, we make use of similar logic but leverage the new type and method based Zigzag system libraries to derive the indicator.
🎲 Design Overview
Similar to Recursive Auto Pitchfork, here too the indicator code is around 50 lines. Whereas most of the heavy lifting is done by the libraries.
🎲 Base Libraries
Base libraries are those which does not have any dependency. They form basic structures which are later used in other libraries. These libraries need to be crafted carefully so that minimal updates are done later on. Any updates on these libraries will impact all the dependent libraries and scripts.
🎯 Drawing
DrawingTypes - Defines basic drawing types Point, Line, Label, Box, Linefill and related property types.
DrawingMethods - All the methods or functionality surrounding Basic types are defined here.
🎲 Layer 1 Libraries
These are the libraries which has direct dependency on base libraries.
🎯 Zigzag
ZigzagTypes - Types required for defining Zigzag and Divergence
ZigzagMethods - Methods associated with Zigzag Type definitions.
🎲Indicator
Indicator draws zigzags based on given length. And then recursively derives next level zigzags based on previous levels. As per the utility, indicator is useful in several ways
Visualising price structure based on zigzag pivots - which in turn can help visualise patterns.
Ability to add any oscillator makes it easy to spot divergences with choice of indicators.
Programmers can use the derived values to build complex algorithms such as automatic pattern recognition.
🎯 Settings
Settings are explained via tooltips. These are very much straight forward and directly related to zigzag, oscillators and divergence.
Recursive Auto-Pitchfork [Trendoscope]"Say Hi" to object oriented programming with Pinescript using types and methods. This is the beginning of new era of Pinescript where we are moving from isolated scripts containing indicator and strategies to whole ecosystem of Object Oriented Programming with libraries of highly reusable components. Those who are familiar with programming would have already realised how big these improvements are and what it brings to the table.
With this script, I am not just providing an indicator for traders but also an introduction for programmers on how to design and build object oriented components in Pinescript using types and methods. Big thanks to Tradingview and Pine development team for making this happen. We look forward for many such gifts in the future :)
🎲 Architecture
As mentioned before, we are not just building an indicator here. But, an ecosystem of components. Using Types and Methods we can visualise libraries as Classes. Thus, we can build an ecosystem of libraries in layered approach to enhance effective code reusability.
Generic architecture can be visualised as below
Coming to the specific case of Auto Pitchfork indicator, the indicator code is less than 50 lines for logic and around 100 lines of inputs. But, most of the heavy-lifting is done by the libraries underneath. Here is a snapshot of related libraries and how they are connected.
All libraries are divided into two portions.
Types - Contains only type definitions
Methods - Contains only method definitions related to the types defined in the Types library
Together, these libraries can be visualised as Class. Methods are defined in such a way all exported methods are related to Types and no other functions or features are defined. If we need further functionality which does not depend on the types, we need to do this via some other library and use them here. Similarly, we should not define any methods related to these types in other libraries.
Reason for splitting the libraries to types and methods is to enable updating methods without disturbing types. Since libraries create interdependencies due to versioning, it is best if we do less updates on the type definitions. Splitting the two enables adding more features while keeping the type definition version intact.
🎲 Base Libraries
Base libraries are those which does not have any dependency. They form basic structures which are later used in other libraries. These libraries need to be crafted carefully so that minimal updates are done later on. Any updates on these libraries will impact all the dependent libraries and scripts.
🎯 Drawing

DrawingMethods - All the methods or functionality surrounding Basic types are defined here.
🎲 Layer 1 Libraries
These are the libraries which has direct dependency on base libraries.
🎯 Zigzag
ZigzagTypes - Types required for defining Zigzag and Divergence
ZigzagMethods - Methods associated with Zigzag Type definitions.
🎯Pitchfork
PitchforkTypes - Basic and Drawing Types for Pitchfork objects
PitchforkMethods - Methods associated with Pitchfork type definitions
🎲 Indicator and Settings
Indicator draws pitchfork based on recursive zigzag configurations. Recursive zigzag is derived with following logic:
Base level zigzag is calculated with regular zigzag algorithm with given length and depth
Next level zigzag is calculated based on base zigzag. And we recursively calculate higher level zigzags until we are left with 4 or less pivots or when no further reduction is possible
On every level of zigzag, we then check the last 3 pivots and draw pitchfork based on the retracement ratio.
Indicator settings are summarised in the tooltips and are as below.
Finally, big thanks to my partner @CryptoArch_ for bringing up the topic of pitchfork for our next development.

RSI Impact Heat Map [Trendoscope]Here is a simple tool to measure and display outcome of certain RSI event over heat map.
🎲 Process
🎯Event
Event can be either Crossover or Crossunder of RSI on certain value.
🎯Measuring Impact
Impact of the event after N number of bars is measured in terms of highest and lowest displacement from the last close price. Impact can be collected as either number of times of ATR or percentage of price. Impact for each trigger is recorded separately and stored in array of custom type.
🎯Plotting Heat Map
Heat map is displayed using pine tables. Users can select heat map size - which can vary from 10 to 90. Selecting optimal size is important in order to get right interpretation of data. Having higher number of cells can give more granular data. But, chart may not fit into the window. Having lower size means, stats are combined together to get less granular data which may not give right picture of the results. Default value for size is 50 - meaning data is displayed in 51X51 cells.
Range of the heat map is adjusted automatically based on min and max value of the displacement. In order to filter out or merge extreme values, range is calculated based on certain percentile of the values. This will avoid displaying lots of empty cells which can obscure the actual impact.
🎲 Settings
Settings allow users to define their event, impact duration and reference, and few display related properties. The description of these parameters are as below:
🎲 Use Cases
In this script, we have taken RSI as an example to measure impact. But, we can do this for any event. This can be price crossing over/under upper/lower bollinger bands, moving average crossovers or even complex entry or exit conditions. Overall, we can use this to plot and evaluate our trade criteria.
🎲 Interpretation
Q1 - If more coloured dots appear on the top right corner of the table, then the event is considered to trigger high volatility and high risk environment.
Q2 - If more coloured dots appear on the top left corner, then the events are considered to trigger bearish environment.
Q3 - If more coloured dots appear on the bottom left corner of the chart, then the events are considered insignificant as they neither generate higher displacement in positive or negative side. You can further alter outlier percentage to reduce the bracket and hence have higher distribution move towards
Q4 - If more coloured dots appear on the bottom right corner, then the events are considered to trigger bullish environment.
Will also look forward to implement this as library so that any conditions or events can be plugged into it.
Bar MagnifierMany times while developing algos based on patterns and reversals, I come across issues which needs lower timeframe inspection. Loading multiple charts and comparing equivalent lower timeframe is slightly cumbersome at times. Hence, I thought of building this simple tool - which will instantly provide me lower timeframe candles for given candle. Since the candle selection happen via confirmed time input, we can use this as slider to move from one candle to other for inspection.
🎲 Usage
🎯Loading the script
When you load the script, a prompt appears which asks you to select a time by clicking on the chart.
Select the bar you want to magnify and study
🎯Components
Once loaded, you can see the marker which tells which bar is magnified. And you can also see all the lower timeframe candles before that point. Please note that due to pine restrictions, we can only show last 250 lower timeframe bars. You can change the lower timeframe via settings to cover if the chart timeframe is very high.
🎯Moving to different bars
Click on the middle of the marker, you will see slider which you can slide to move from one bar to other.
Example, after sliding, you will see the lower timeframe data of new candle.
🎯Settings
Settings has only two inputs.
Bar time - selects the bar which needs to be inspected.
Lower timeframe - Default is 1 min. And select a timeframe according to your chart timeframe. Less than 1 min is not supported by security.lower_tf function. Hence, will not work.

Band-Zigzag - TrendFollower Strategy [Trendoscope]Strategy Time!!!
Have built this on my earlier published indicator Band-Zigzag-Trend-Follower . This is just one possible implementation of strategy on Band-Based-Zigzag .
🎲 Notes
Experimental prototype. Not financial advise and strategy not guaranteed to make money despite backtest results
Not created or tested for any specific instrument or timeframe
Test and adopt with own risk
🎲 Strategy
This is trend following strategy built based on Bands and Zigzag. Traits of trend following strategies are
Lower win rate (Yes, thats right)
High risk reward (Compensates low win rate)
Higher drawdown
If market is choppy, trend following methods suffer.
The script implements few points to overcome the negatives such as lower win rate and higher drawdown by actively assessing pivots on the direction of trend along. This helps us take regular profits and exit on time during the end of trend. Most of the other concepts are defined and explained in indicator - Band-Zigzag-Trend-Follower and Band-Based-Zigzag
Defining a trend following method is simple. Basic rule of trend following is Buy High and Sell Low (Yes, you heard it right). To explain further - methodology involve finding an established trend which is flying high and join the trend with proper risk and optimal stop. Once you get into the trade, you will not exit unless there is change in the trend. Or in other words, the parameters which you used to define trend has reversed and the trend is not valid anymore.
🎯 Using bands
When price breaks out of upper bands (example, Bollinger Band , Keltener Channel, or Donchian Channel), with a pre determined length and multiplier, we can consider the trend to be bullish and similarly when price breaks down the lower band, we can consider the trend to be bearish .
🎯 Using Pivots
Simple logic using zigzag or pivot points is that when price starts making higher highs and higher lows, we can consider this as uptrend. And when price starts making lower highs and lower lows, we can consider this as downtrend. There are few supertrend implementations I have published in the past based on zigzags and pivot points .
Drawbacks of both of these methods is that there will be too many fluctuations in both cases unless we increase the reference length. And if we increase the reference length, we will have higher drawdown.
🎯 Band Based Zigzag Method
Here we use bands to define our pivot high and pivot low - this makes sure that we are identifying trend only on breakouts as pivots are only formed on breakouts
Our method also includes pivot ratio to cross over 1.0 to be able to consider it as trend. This means, we are waiting for price also to make new high high or lower low before making the decision on trend. But, this helps us ignore smaller pivot movements due to the usage of bands.
I have also implemented few tricks such as sticky bands (Bands will not contract unless there is breakout) and Adaptive Bands (Band will not expand unless price is moving in the direction of band). This makes the trend following method very robust.
To avoid fakeouts, we also use percentB of high/low in comparison with price retracement to define breakout.
🎲 Settings
Settings are fairly simpler and are explained as below. You will find most of the required information in tooltips.
