Weekly Auto-Fib Zones (Custom Colors)

This script automatically plots weekly Fibonacci-based zones using the current week’s high and low. It updates dynamically as new price action forms and provides optional visual regions for key retracement areas.

The indicator includes:
• Weekly high/low anchor lines
• Optional 0.11–0.17 zones
• Optional 0.5 midpoint (premium/discount)
• Optional 0.618–0.786 retracement band
• Customizable colors for each level
• Dynamic boxes that expand as the week progresses

It is designed as a visual aid for identifying weekly ranges, contextual zones, and potential areas of interest based solely on Fibonacci percentages. No signals, alerts, or trading recommendations are included.
