Emitter + Extensive [CLEVER]

The provided script is a complex, two-part Pine Script indicator designed for use on TradingView. It combines two main strategies: the Emitter [CLEVER] module for generating trading signals using an oscillator, and the Extensive [CLEVER] module for identifying trend direction and potential liquidity zones using a variation of the Variable Index Dynamic Average .
Here is a description of its components and function:

Emitter [CLEVER] Module
This module is designed to generate specific buy/sell signals based on a modified Relative Strength Index (RSI) oscillator.
Core Logic: It calculates the RSI (Length 10) and applies a custom smoothing technique called "Discontinued Signal Lines (DSL)" and a "Zero-Lag Exponential Moving Average (ZLEMA)". This creates an oscillator line (dsl_osc) and upper/lower bounds (level_up, level_dn).
Timeframes: It supports multi-timeframe (MTF) analysis, allowing the user to view oscillator signals calculated from a different timeframe than the one currently displayed on the chart via the request.security() function.
Signals:
Buy (Up) Signal: A green triangle appears below the bar when the oscillator crosses above its lower DSL line (level_dn) and the oscillator is below 55 (suggesting a potential entry from oversold conditions). The background and candle color turn green.
Sell (Down) Signal: A red triangle appears above the bar when the oscillator crosses below its upper DSL line (level_up) and the oscillator is above 50. The background and candle color turn red.
Visuals: It uses plotshape for triangles, bgcolor for background shading, and plotcandle to color the actual price candles based on the identified trend signals.
Extensive [CLEVER] Module
This module is intended to identify the primary market trend and potential areas of support/resistance ("liquidity levels"). The latter part of this module relating to drawing liquidity lines appears to be incomplete or disabled in the provided code.
Core Logic: It utilizes the VIDYA (Variable Index Dynamic Average), a moving average that adjusts its smoothing factor based on market volatility (momentum). The ta.atr(200) is used to measure volatility.
Trend Identification:
It calculates upper and lower bands around the VIDYA value using an ATR multiplier (band_distance).
The is_trend_up boolean variable changes state when the price (src_tf) crosses these bands.
The indicator defines an uptrend when the price crosses above the upper_band, and a downtrend when the price crosses below the lower_band.
Liquidity/Support (Incomplete): The script initializes arrays (liquidity_lines_low, liquidity_lines_high) and a placeholder extend_liquidity_lines function, suggesting an intent to plot historical pivot points or support/resistance lines that get extended across the chart. However, this functionality is not fully implemented in the provided snippet.
Summary
The combined indicator provides a comprehensive trading view:
Trend Context: The "Extensive" module establishes the overarching direction (up or down trend) based on volatility-adjusted moving averages.
Entry Signals: The "Emitter" module provides specific, colored visual signals (triangles and candle colors) when an underlying oscillator moves into favorable positions within that trend context.
Customization: Both modules offer user inputs to adjust lengths, momentum factors, distance factors, and timeframes, making it highly customizable within the TradingView interface
