ma_libraryTitle: Library: Advanced Moving Average Collection
Description:
This library provides a comprehensive set of Moving Average algorithms, ranging from standard filters (SMA, EMA) to adaptive trendlines (KAMA, FRAMA) and experimental smoothers (ALMA, JMA).
It has been fully optimized for Pine Script v6, ensuring efficient execution and strict robustness against na (missing) values. Unlike standard implementations that propagate na values, these functions dynamically recalculate weights to maintain continuity in disjointed datasets.
🧩 Library Features
Robustness: Non-recursive filters ignore na values within the lookback window. Recursive filters maintain state to prevent calculation breaks.
Optimization: Logic updated to v6 standards, utilizing efficient loops and var persistence.
Standardization: All functions utilize a consistent f_ prefix and standardized parameters for easy integration.
Scope: Contains over 35 different smoothing algorithms.
📊 Input Requirements
Source (src): The data series to smooth (usually close, hl2, etc.).
Length (length): The lookback period (must be a simple int).
Specifics: Some adaptive MAs (like f_evwma) require volume data, while others (like f_alma) require offset/sigma settings.
🛠️ Integration Example
You can import the library and call functions directly, or use the built-in f_selector to create dynamic inputs for your users.

// --- Example 1: Direct Function Call ---
// calculating Jurik Moving Average (JMA)
float jma_val = ma.f_jma(close, 14)

// --- Example 2: User Selector ---
// Allowing the user to choose the MA type via settings
string selected_type = input.string("ALMA", "MA Type", options= )
int length = input.int(20, "Length")
// Using the generic selector function
float dynamic_ma = ma.f_selector(close, length, selected_type)
