Based on the Pine Script code you provided, here is a detailed description of the indicator's features and functionality.

Indicator Overview
This is the Heikin Ashi RSI Oscillator (HARSI), a custom-built indicator for TradingView. It combines the principles of Heikin Ashi candles and the Relative Strength Index (RSI) to provide a smoothed, trend-focused oscillator in a separate pane below the main chart. The indicator visualizes trend strength, overbought/oversold conditions, and momentum changes using a series of configurable plots and lines.

Key Components and Features
Heikin Ashi RSI Candles: This is the core component. Instead of traditional price data, the indicator uses a custom Heikin Ashi calculation applied to the RSI values. This creates a smoothed, momentum-driven "candle" visualization that filters out market noise, making it easier to identify the direction and strength of the trend. The color of these candles changes to reflect bullish (teal) or bearish (red) momentum.

RSI Plot & Histogram: The indicator includes a standard RSI line plot and an optional histogram. The RSI can be displayed in "Smoothed Mode," which applies a Heikin Ashi-like smoothing to the RSI line itself to reduce volatility and improve trend identification. The histogram visually represents the RSI's value, with its height corresponding to the magnitude of the RSI.

Stochastic RSI: An optional Stochastic RSI is included to provide a different perspective on momentum. This is a "momentum of momentum" indicator that can be used for confirming trend changes or identifying overbought/oversold conditions within the RSI's own range. It can be plotted as either a ribbon (showing the K and D lines filled) or as individual lines.

Bollinger Bands (Stepline Style): The indicator overlays Bollinger Bands on the RSI. These bands adapt to the volatility of the RSI, providing dynamic overbought and oversold levels. The middle band is a simple moving average of the RSI. The upper and lower bands are plotted using a stepline style, giving them a distinct, staggered appearance.

Horizontal Lines: Several fixed horizontal lines are plotted to define key zones:

Overbought/Oversold (OB/OS) Zones: Customizable horizontal lines define overbought and oversold regions, with additional lines for "extreme" levels. These are based on the indicator's zero-median scale.

Traditional RSI Levels: Optional dotted horizontal lines at 70, 50, and 30 help users who are accustomed to traditional RSI readings quickly identify overbought, neutral, and oversold conditions.
