RSI + Composite RSI with Regular & Hidden Divergences

📌 Description (for TradingView Public Publishing):
RSI Composite Pro is a reimagined version of the classic RSI indicator, enhanced with deeper insights. This tool displays both the standard RSI of the current asset and a normalized RSI derived from a reference index (e.g., XU100, NDX, SPX), all on the same panel.

By default, the composite RSI source is automatically selected based on the exchange you're viewing (e.g., BIST → XU100, NASDAQ → NDX, NYSE → SPX). However, users can also manually input any symbol through the settings panel.

Additionally, you can apply smoothing filters such as SMA, EMA, or Bollinger Bands to both RSI lines.
The script also detects regular and hidden divergences on RSI, helping to identify potential trend reversal points.

Key Features:

Dual RSI view: asset RSI vs. composite market RSI

Auto or manual selection of composite RSI source

Supports MA smoothing and Bollinger Band overlays

Automatic detection of regular & hidden divergences

Clean and customizable visualization on a single chart

This indicator is flexible and can be tailored to your trading style, suitable for both short-term trading and trend analysis.
