Library "ottlib"
█ OVERVIEW
This library contains functions for the calculation of the OTT (Optimized Trend Tracker) and its variants, originally created by Anıl Özekşi (Anil_Ozeksi). Special thanks to him for the concept and to Kıvanç Özbilgiç (KivancOzbilgic) and dg_factor (dg_factor) for adapting them to Pine Script.
█ WHAT IS "OTT"
The OTT (Optimized Trend Tracker) is a highly customizable and very effective trend-following indicator that relies on moving averages and a trailing stop at its core. Moving averages help reduce noise by smoothing out sudden price movements in the markets, while trailing stops assist in detecting trend reversals with precision. Initially developed as a noise-free trailing stop, the current variants of OTT range from rapid trend reversal detection to long-term trend confirmation, thanks to its extensive customizability.
It's well-known variants are:
█ LIBRARY FEATURES
This library has been prepared in accordance with the style, coding, and annotation standards of Pine Script version 5. As a result, explanations and examples will appear when users hover over functions or enter function parameters in the editor.
█ USAGE
Usage of this library is very simple. Just import it to your script with the code below and use its functions.
█ FUNCTIONS
• f_vidya(source, length, cmoLength)
Short Definition: Chande's Variable Index Dynamic Average (VIDYA).
Details: This function computes Chande's Variable Index Dynamic Average (VIDYA), which serves as the original moving average for OTT. The 'length' parameter determines the number of bars used to calculate the average of the given source. Lower values result in less smoothing of prices, while higher values lead to greater smoothing. While primarily used internally in this library, it has been made available for users who wish to utilize it as a moving average or use in custom OTT implementations.
Parameters:
source (float): (series float) Series of values to process.
length (simple int): (simple int) Number of bars to lookback.
cmoLength (simple int): (simple int) Number of bars to lookback for calculating CMO. Default value is `9`.
Returns: (float) Calculated average of `source` for `length` bars back.
Example:
• f_mostTrail(source, multiplier)
Short Definition: Calculates trailing stop value.
Details: This function calculates the trailing stop value for a given source and the percentage. The 'multiplier' parameter defines the percentage of the trailing stop. Lower values are beneficial for catching short-term reversals, while higher values aid in identifying long-term trends. Although only used once internally in this library, it has been made available for users who wish to utilize it as a traditional trailing stop or use in custom OTT implementations.
Parameters:
source (float): (series int/float) Series of values to process.
multiplier (simple float): (simple float) Percent of trailing stop.
Returns: (float) Calculated value of trailing stop.
Example:
• f_ottTrail(source, multiplier)
Short Definition: Calculates OTT-specific trailing stop value.
Details: This function calculates the trailing stop value for a given source in the manner used in OTT. Unlike a traditional trailing stop, this function modifies the traditional trailing stop value from two bars prior by adjusting it further with half the specified percentage. The 'multiplier' parameter defines the percentage of the trailing stop. Lower values are beneficial for catching short-term reversals, while higher values aid in identifying long-term trends. Although primarily used internally in this library, it has been made available for users who wish to utilize it as a trailing stop or use in custom OTT implementations.
Parameters:
source (float): (series int/float) Series of values to process.
multiplier (simple float): (simple float) Percent of trailing stop.
Returns: (float) Calculated value of OTT-specific trailing stop.
Example:
• ott(source, length, multiplier)
Short Definition: Calculates OTT (Optimized Trend Tracker).
Details: The OTT consists of two lines. The first, known as the "Support Line", is the VIDYA of the given source. The second, called the "OTT Line", is the trailing stop based on the Support Line. The market is considered to be in an uptrend when the Support Line is above the OTT Line, and in a downtrend when it is below.
Parameters:
source (float): (series float) Series of values to process. Default value is `close`.
length (simple int): (simple int) Number of bars to lookback. Default value is `2`.

Example:
• tott(source, length, multiplier, bandsMultiplier)
Short Definition: Calculates TOTT (Twin OTT).
Details: TOTT consists of three lines: the "Support Line," which is the VIDYA of the given source; the "Upper Line," a trailing stop of the Support Line adjusted with an added multiplier; and the "Lower Line," another trailing stop of the Support Line, adjusted with a reduced multiplier. The market is considered in an uptrend if the Support Line is above the Upper Line and in a downtrend if it is below the Lower Line.
Parameters:
source (float): (series float) Series of values to process. Default value is `close`.
length (simple int): (simple int) Number of bars to lookback. Default value is `40`.

v2█ UPDATES
- Fixed `f_vidya()` function for more robust initialization by incorporating a conditional check to set the initial value to the Simple Moving Average (SMA) when previous VIDYA value is not available, ensuring more accurate calculations from the start. This change effectively handles edge cases where the length is set to 1, aligning the function closer to the standard VIDYA methodology and enhancing overall reliability.
- Fixed an error at `risotto()` function that that involves calculation of `supportLine`.
█ NEW FUNCTIONS
• totto(source, length, multiplier, bandsMultiplier)
Short Definition: Calculates TOTTO (Another version of Twin OTT).
Details: TOTTO consists of three lines: the "Support Line," which is the VIDYA of the given source; the "Upper Line," a trailing stop of the Support Line adjusted with an added multiplier; and the "Lower Line," another trailing stop of the Support Line, adjusted with a reduced multiplier. The market is considered in an uptrend if the Support Line is above the Upper Line and in a downtrend if it is below the Lower Line. It's very much like TOTT but difference comes from calculation of VIDYA which uses half of the given length and other lines uses the OTT of the Support Line's VIDYA for 2 bar length.
Parameters:
source (float): (series float) Series of values to process. Default value is `close`.
length (simple int): (simple int) Number of bars to lookback. Default value is `35`.
multiplier (simple float): (simple float) Percent of trailing stop. Default value is `0.5`.
bandsMultiplier (simple float): Multiplier for bands. Default value is `0.0006`.
Returns: ([[]float, float, float[]]) Tuple of `supportLine`, `upperLine` and `lowerLine`.
