pseudorenko█ CALCULATE PSEUDO-RENKO VALUE
Calculates and returns the Pseudo-Renko Stabilized value (or close price) based on a given input value, along with the direction of the current Renko brick. This function adapts the traditional Renko brick size dynamically based on the volatility of the input value using a combination of SMA and EMA calculations. The calculated price represents the closing price of the most recent Pseudo-Renko brick, while the direction indicates the trend ( 1 for uptrend, -1 for downtrend).
Parameters:
* `val` :
* Type: ` float `
* Description: The input value upon which the Pseudo-Renko calculations are performed. You can use any price series or custom value as input.
* `sensitivity` :
* Type: ` float `
* Default Value: ` 1.0 `
* Description: Controls the sensitivity of the brick size to the volatility of the `val`. Higher values lead to larger bricks, resulting in a smoother Renko chart. Lower values produce smaller bricks, leading to a more reactive chart.
* Possible Values: Any positive float.
* `length` :
* Type: ` int `
* Default Value: ` 7 `
* Description: The length used for calculating the EMA and SMA in the dynamic brick size calculation. It influences how quickly the brick size adapts to changing volatility of the `val`.
* Possible Values: Any positive integer.
Return Values:
* `lastRenkoClose` :
* Type: ` float `
* Description: The closing price of the last completed Pseudo-Renko brick based on the `val`.
* `renkoDirection` :
* Type: ` int `
* Description: The direction of the current Pseudo-Renko brick based on the `val`:
* ` 1 `: Uptrend
* ` -1 `: Downtrend
* ` 0 `: No change (initially, or no brick change since the previous bar)
Example Usage:
//@version=5
indicator("Pseudo-Renko Stabilized (Val)", overlay=true)
// Get user inputs
sensitivityInput = input.float(0.1, "Sensitivity",0.01,step=0.01)
lengthInput = input.int(5, "Length",2)
// Example usage with the 'close' price as the input value
= pseudo_renko(math.avg(close,open), sensitivityInput, lengthInput)
// Plot the Renko close price
plot(renkoClose, "Renko Close", renkoDirection>0?color.aqua:color.orange,2)
// You can also use other values as input, such as:
// = pseudo_renko(high, sensitivityInput, lengthInput)
// = pseudo_renko(low, sensitivityInput, lengthInput)
This example demonstrates how to use the `pseudo_renko` function within an indicator. It takes user inputs for `sensitivity` and `length`, then calculates the Pseudo-Renko values using the average of the `close` and `open` prices as the `val`. The resulting `renkoClose` price is plotted on the chart, with a color change based on the `renkoDirection`. It also illustrates how you can use other values, like `high` and `low`, as input to the function.
Note: The Pseudo-Renko algorithm is based on adapting the Renko brick size dynamically based on the input `val`. This provides more flexibility compared to the normal, but is experimental. The `sensitivity` and `length` parameters, along with the choice of the `val`, offer further customization to tune the algorithm's behavior to your preference and trading style.

[ALGOA+] Markov Chains Library by @metacamaleoLibrary "MarkovChains"
Markov Chains library by @metacamaleo. Created in 09/08/2024.
This library provides tools to calculate and visualize Markov Chain-based transition matrices and probabilities. This library supports two primary algorithms: a rolling window Markov Chain and a conditional Markov Chain (which operates based on specified conditions). The key concepts used include Markov Chain states, transition matrices, and future state probabilities based on past market conditions or indicators.
Key functions:
- `mc_rw()`: Builds a transition matrix using a rolling window Markov Chain, calculating probabilities based on a fixed length of historical data.
- `mc_cond()`: Builds a conditional Markov Chain transition matrix, calculating probabilities based on the current market condition or indicator state.
Basically, you will just need to use the above functions on your script to default outputs and displays.
Exported UDTs include:
- s_map: An UDT variable used to store a map with dummy states, i.e., if possible states are bullish, bearish, and neutral, and current is bullish, it will be stored
in a map with following keys and values: "bullish", 1; "bearish", 0; and "neutral", 0. You will only use it to customize your own script, otherwise, it´s only for internal use.
- mc_states: This UDT variable stores user inputs, calculations and MC outputs. As the above, you don´t need to use it, but you may get features to customize your own script.
For example, you may use mc.tm to get the transition matrix, or the prob map to customize the display. As you see, functions are all based on mc_states UDT. The s_map UDT is used within mc_states´s s array.
Optional exported functions include:
- `mc_table()`: Displays the transition matrix in a table format on the chart for easy visualization of the probabilities.
- `display_list()`: Displays a map (or array) of string and float/int values in a table format, used for showing transition counts or probabilities.
- `mc_prob()`: Calculates and displays probabilities for a given number of future bars based on the current state in the Markov Chain.
- `mc_all_states_prob()`: Calculates probabilities for all states for future bars, considering all possible transitions.
The above functions may be used to customize your outputs. Use the returned variable mc_states from mc_rw() and mc_cond() to display each of its matrix, maps or arrays using mc_table() (for matrices) and display_list() (for maps and arrays) if you desire to debug or track the calculation process.
See the examples in the end of this script.
Have good trading days!
Best regards,
@metacamaleo

Color Library // AlgoFyreAlgoFyre's Color Library is a Pine Script v5 library offering fire-themed palettes with light and dark modes. It helps traders easily integrate consistent, visually appealing color schemes into TradingView indicators. Used in AlgoFyre's Scripts and Indicators.
Color Overview
The AlgoFyreColorLibrary includes a comprehensive set of colors inspired by fire, ranging from light reds and oranges to dark browns and deep reds. The library is divided into two main themes:
Light Theme:
Includes lighter shades of red, orange, and brown, suitable for use on light backgrounds.
Dark Theme:
Includes darker shades of red, orange, and brown, suitable for use on dark backgrounds.
How to Use
To use the AlgoFyreColorLibrary in your Pine Script indicators and strategies, follow these steps:
Import the Library:
Import the AlgoFyreColorLibrary at the beginning of your script.
Call the getColor Function:
Use the getColor function to retrieve the desired color with the specified transparency.
Example
//@version=5
import "AF-L-0001" as af
// Example usage of getColor function
color primaryColor = af.getColor("af_primary1", 50)
color signalColor = af.getColor("af_green", 80)
// Plotting example
plot(close, color=primaryColor, linewidth=2, title="Primary Color Line")
plot(close, color=signalColor, linewidth=2, title="Signal Color Line")
The library AF-L-0001 is imported with the alias af.
The getColor function is used to get colors with specified transparency.
The colors are then used to plot lines on the chart.

lib_no_delayLibrary "lib_no_delay"
This library contains modifications to standard functions that return na before reaching the bar of their 'length' parameter.
That is because they do not compromise speed at current time for correct results in the past. This is good for live trading in short timeframes but killing applications on Monthly / Weekly timeframes if instruments, like in crypto, do not have extensive history (why would you even trade the monthly on a meme coin ... not my decision).
Also, some functions rely on source (value at previous bar), which is not available on bar 1 and therefore cascading to a na value up to the last bar ... which in turn leads to a non displaying indicator and waste of time debugging this)
Anyway ... there you go, let me know if I should add more functions.
sma(source, length)
Parameters:
source (float) : Series of values to process.
length (simple int) : Number of bars (length).
Returns: Simple moving average of source for length bars back.
ema(source, length)
Parameters:
source (float) : Series of values to process.
length (simple int) : Number of bars (length).
Returns: (float) The exponentially weighted moving average of the source.
rma(source, length)
Parameters:
source (float) : Series of values to process.
length (simple int) : Number of bars (length).
Returns: Exponential moving average of source with alpha = 1 / length.
atr(length)
Function atr (average true range) returns the RMA of true range. True range is max(high - low, abs(high - close ), abs(low - close )). This adapted version extends ta.atr to start without delay at first bar and deliver usable data instead of na by averaging ta.tr(true) via manual SMA.
Parameters:
length (simple int) : Number of bars back (length).
Returns: Average true range.
rsi(source, length)
Relative strength index. It is calculated using the ta.rma() of upward and downward changes of source over the last length bars. This adapted version extends ta.rsi to start without delay at first bar and deliver usable data instead of na.
Parameters:
source (float) : Series of values to process.
length (simple int) : Number of bars back (length).
Returns: Relative Strength Index.
ToClrToStrContains functions for conversion of color to string and vice versa:
method toClr( string this ) - converts string reperesentation of color (in hex format) to color
method toHex( color this ) - converts color to string (hex form)
method toRgb( color this ) - converts color to string ("rgb(11,11,11,0)" form)

Time Zone CorrectorThe Time Zone Corrector library provides a utility function designed to adjust time based on the user's current time zone. This library supports a wide range of time zones across the Americas, Europe, Asia, and Oceania, making it highly versatile for traders around the world. It simulates a switch-case structure using ternary operators to output the appropriate time offset relative to UTC.
Whether you're dealing with market sessions in New York, Tokyo, London, or other major trading hubs, this library helps ensure your trading algorithms can accurately account for time differences. The library is particularly useful for strategies that rely on precise timing, as it dynamically adjusts the time zone offset depending on the symbol being traded.
SessionLibrary "Session"
Helper functions for trading sessions. TradingView doesn't provide correct data when
calling some of the convenience methods like session.ismarket when you are looking at futures charts. This library corrects those mistakes by providing functions with the same names as the TradingView default properties. that reference a custom defined set of session hours for futures. It also provides a way for consumers to customize the map values by calling getSessionMap() and then overwriting (or adding) custom session definitions.

iteratorThe "Iterator" library is designed to provide a flexible way to work with sequences of values. This library offers a set of functions to create and manage iterators for various data types, including integers, floats, and more. Whether you need to generate an array of values with specific increments or iterate over elements in reverse order, this library has you covered.
Key Features:
Array Creation: Easily generate arrays of integers or floats with customizable steps, both inclusive and exclusive of the end values.
Flexible Iteration: Includes methods to iterate over arrays of different types, such as booleans, integers, floats, strings, colors, and drawing objects like lines and labels.
Reverse Iteration: Support for reverse iteration, giving you control over the order in which elements are processed.
Automatic Loop Control: One of the key advantages of this library is that when using the .iterate() method, it only loops over the array when there are values present. This means you don’t have to manually check if the array is populated before iterating, simplifying your code and reducing potential errors.
Versatile Use Cases: Ideal for scenarios where you need to loop over an array without worrying about empty arrays or checking conditions manually.
This library is particularly useful in cases where you need to perform operations on each element in an array, ensuring that your loops are efficient and free from unnecessary checks.

csv_series_libraryThe CSV Series Library is an innovative tool designed for Pine Script developers to efficiently parse and handle CSV data for series generation. This library seamlessly integrates with TradingView, enabling the storage and manipulation of large CSV datasets across multiple Pine Script libraries. It's optimized for performance and scalability, ensuring smooth operation even with extensive data.
Features:
Multi-library Support: Allows for distribution of large CSV datasets across several libraries, ensuring efficient data management and retrieval.
Dynamic CSV Parsing: Provides robust Python scripts for reading, formatting, and partitioning CSV data, tailored specifically for Pine Script requirements.
Extensive Data Handling: Supports parsing CSV strings into Pine Script-readable series, facilitating complex financial data analysis.
Automated Function Generation: Automatically wraps CSV blocks into distinct Pine Script functions, streamlining the process of integrating CSV data into Pine Script logic.
Usage:
Ideal for traders and developers who require extensive data analysis capabilities within Pine Script, especially when dealing with large datasets that need to be partitioned into manageable blocks. The library includes a set of predefined functions for parsing CSV data into usable series, making it indispensable for advanced trading strategy development.
Example Implementation:
CSV data is transformed into Pine Script series using generated functions.
Multiple CSV blocks can be managed and parsed, allowing for flexible data series creation.
The library includes comprehensive examples demonstrating the conversion of standard CSV files into functional Pine Script code.
To effectively utilize the CSV Series Library in Pine Script, it is imperative to initially generate the correct data format using the accompanying Python program. Here is a detailed explanation of the necessary steps:
1. Preparing the CSV Data:
The Python script provided with the CSV Series Library is designed to handle CSV files that strictly contain no-space, comma-separated single values. It is crucial that your CSV file adheres to this format to ensure compatibility and correctness of the data processing.
2. Using the Python Program to Generate Data:
Once your CSV file is prepared, you need to use the Python program to convert this file into a format that Pine Script can interpret. The Python script performs several key functions:
Reads the CSV file, ensuring that it matches the required format of no-space, comma-separated values.
Formats the data into blocks, where each block is a string of data that does not exceed a specified character limit (default is 4,000 characters). This helps manage large datasets by breaking them down into manageable chunks.
Wraps these blocks into Pine Script functions, each block being encapsulated in its own function to maintain organization and ease of access.
3. Generating and Managing Multiple Libraries:
If the data from your CSV file exceeds the Pine Script or platform limits (e.g., too many characters for a single script), the Python script can split this data into multiple blocks across several files.
4. Creating a Pine Script Library:
After generating the formatted data blocks, you must create a Pine Script library where these blocks are integrated. Each block of data is contained within its function, like my_csv_0(), my_csv_1(), etc. The full_csv() function in Pine Script then dynamically loads and concatenates these blocks to reconstruct the full data series.
5. Exporting the full_csv() Function:
Once your Pine Script library is set up with all the CSV data blocks and the full_csv() function, you export this function from the library. This exported function can then be used in your actual trading projects. It allows Pine Script to access and utilize the entire dataset as if it were a single, continuous series, despite potentially being segmented across multiple library files.
6. Reconstructing the Full Series Using vec :
When your dataset is particularly large, necessitating division into multiple parts, the vec type is instrumental in managing this complexity. Here’s how you can effectively reconstruct and utilize your segmented data:
Definition of vec Type: The vec type in Pine Script is specifically designed to hold a dataset as an array of floats, allowing you to manage chunks of CSV data efficiently.
Creating an Array of vec Instances: Once you have your data split into multiple blocks and each block is wrapped into its own function within Pine Script libraries, you will need to construct an array of vec instances. Each instance corresponds to a segment of your complete dataset.
Using array.from(): To create this array, you utilize the array.from() function in Pine Script. This function takes multiple arguments, each being a vec instance that encapsulates a data block. Here’s a generic example:
vec series_vector = array.from(vec.new(data_block_1), vec.new(data_block_2), ..., vec.new(data_block_n))
In this example, data_block_1, data_block_2, ..., data_block_n represent the different segments of your dataset, each returned from their respective functions like my_csv_0(), my_csv_1(), etc.
Accessing and Utilizing the Data: Once you have your vec array set up, you can access and manipulate the full series through Pine Script functions designed to handle such structures. You can traverse through each vec instance, processing or analyzing the data as required by your trading strategy.
This approach allows Pine Script users to handle very large datasets that exceed single-script limits by segmenting them and then methodically reconstructing the dataset for comprehensive analysis. The vec structure ensures that even with segmentation, the data can be accessed and utilized as if it were contiguous, thus enabling powerful and flexible data manipulation within Pine Script.

DynamicRSILibrary "DynamicRSI"
The "DynamicRSI" library provides a method to calculate a Dynamic Relative Strength Index (RSI) that adjusts its sensitivity based on market volatility. By combining short and long RSI periods with a weighted average influenced by the market's volatility, this library allows users to obtain a more responsive RSI tailored to changing market conditions.
"DynamicRSI" 라이브러리는 시장 변동성에 따라 감도를 조정하는 동적 상대 강도 지수(RSI)를 계산하는 방법을 제공합니다. 짧은 RSI와 긴 RSI 기간을 시장 변동성에 따라 가중 평균하여 결합함으로써, 이 라이브러리는 시장 상황에 맞게 보다 유연하게 반응하는 RSI를 제공합니다.
Function: drsi(src, minLength, maxLength, volatilityPeriod)
함수: drsi(src, minLength, maxLength, volatilityPeriod)
Parameters:
src (float)
The source data to calculate the RSI (e.g., close price). This is the price data that the RSI is calculated on.
RSI를 계산하기 위한 입력 데이터입니다(예: 종가(close) ). 이 값은 RSI를 계산하는 기준이 되는 가격 데이터입니다.
minLength (simple int)
The period for the shorter RSI. This parameter controls the sensitivity of the RSI, with a shorter period making the RSI more reactive to price changes.
짧은 RSI 기간입니다. 이 매개변수는 RSI의 감도를 제어하며, 더 짧은 기간은 RSI가 가격 변화에 더 민감하게 반응하게 합니다.
maxLength (simple int)
The period for the longer RSI. This parameter provides a smoother RSI, which is less sensitive to short-term price fluctuations.
긴 RSI 기간입니다. 이 매개변수는 더 부드러운 RSI를 제공하며, 단기적인 가격 변동에 덜 민감하게 반응합니다.
volatilityPeriod (simple int)
The period used for calculating the Average True Range (ATR) to measure market volatility. This volatility is then used to adjust the weighting between the short and long RSI, making the final Dynamic RSI more adaptive to market conditions.
시장 변동성을 측정하기 위해 평균 진정 범위(ATR)를 계산하는 기간입니다. 이 변동성을 기반으로 짧은 RSI와 긴 RSI 간의 가중치를 조정하여 최종 Dynamic RSI가 시장 상황에 더 잘 적응할 수 있도록 합니다.
Description:
The drsi function calculates a Dynamic RSI by weighting the short-term and long-term RSI values according to the current market volatility. The function uses the ATR to determine the market's volatility, applying more weight to the short-term RSI when volatility is high and more weight to the long-term RSI when volatility is low. This approach ensures that the RSI is more responsive during volatile periods and smoother during stable periods, providing traders with a more effective tool for identifying overbought and oversold conditions in varying market environments.
drsi 함수는 현재 시장 변동성에 따라 단기와 장기의 RSI 값을 가중치로 조정하여 Dynamic RSI를 계산합니다. 이 함수는 시장의 변동성을 판단하기 위해 ATR을 사용하며, 변동성이 높을 때는 단기 RSI에 더 많은 가중치를 적용하고, 변동성이 낮을 때는 장기 RSI에 더 많은 가중치를 적용합니다. 이 접근 방식은 변동성이 큰 기간 동안 RSI가 더 민감하게 반응하고, 안정적인 기간 동안 더 부드럽게 반응하도록 하여, 다양한 시장 환경에서 과매수 및 과매도 상태를 식별하는 데 보다 효과적인 도구를 제공합니다.
