COMPink RSI Scanner

PURPOSE OF THE INDICATOR
This Pine Script is a comprehensive RSI (Relative Strength Index) scanner and divergence detector designed for TradingView. Its main functions are:
1- Detects RSI divergences (regular and hidden, bullish and bearish).
2- Uses Composite RSI to normalize each stock's RSI against a benchmark index (e.g., BIST:XU100).
3- Scans up to 40 symbols at once from predefined or custom groups.
4- Displays stocks whose RSI or Composite RSI crosses above 50.
KEY FEATURES
1- RSI Divergence Detection
Based on pivot highs/lows in the RSI:
Regular Bullish Divergence: Price makes a lower low while RSI makes a higher low.
Hidden Bullish Divergence: Price makes a higher low while RSI makes a lower low.
Regular Bearish Divergence: Price makes a higher high while RSI makes a lower high.
Hidden Bearish Divergence: Price makes a lower high while RSI makes a higher high.

2- Composite RSI
Normalized RSI using a reference index (default: BIST:XU100).
Helps assess a stock’s relative strength compared to a broader benchmark.

3- Multi-Symbol Scanning
Supports scanning in groups of 40 symbols (selectable via grupSec).
Also supports Custom Symbol List (inputs s01 to s38).
For each symbol:
If RSI crosses above 50 → listed under RSI 50⬆️
If Composite RSI crosses above 50 → listed under K-RSI 50⬆️.

4- On-Chart Labeling
Matching symbols are shown as green and blue labels directly on the chart.
