BC3 2.0

This Pine Script™ code defines an indicator called **“BC3 2.0”**, designed to segment the chart into eight user-defined time windows and visually emphasize key reference levels and price ranges. Here’s a concise overview of its main features:

1. **Customizable Input Parameters**
- Allows the user to set look-back lengths and adjustment factors for the underlying analysis.
- Provides eight distinct date-range inputs, each with a start and end timestamp.

2. **Eight User-Defined Time Ranges**
- Each range can be tailored to any period (days, weeks, months) via simple timestamp inputs.
- Ranges operate independently, so you can compare non-contiguous periods side by side.

3. **Reference Lines for Each Range**
- Draws a persistent horizontal line at a single “reference” level determined for that window.
- Lines are color-coded and vary in transparency to distinguish one range from another.

4. **Shaded Horizontal Bands**
- Fills the area between the highest and lowest prices observed within each range.
- Bands use semi-transparent coloring to keep the main price plot visible underneath.

5. **Overlay-Friendly Design**
- Works directly on the price chart (overlay=true) without adding extra panes.
- Clean styling ensures it integrates seamlessly with other indicators.
