Weekly Open Line

This script is designed to assist traders in identifying the "Power of Three" (PO3) model on a weekly basis — as taught by ICT (Inner Circle Trader).

It automatically plots:
- The **Weekly Open**, a crucial reference level for detecting manipulation zones.
- **Weekly High and Low**, to frame liquidity zones and potential sweep areas.
- A customizable **Manipulation Zone**, calculated as a percentage range above and below the weekly open.

The PO3 model breaks market structure into:
1. Accumulation (early-week range)
2. Manipulation (false breakouts and liquidity grabs)
3. Distribution (true directional move)

This tool helps visualize those stages and align trades with smart money behavior.
Best used on 1H, 4H, or 15M timeframes for clarity.

Tip: Combine with FVGs, Order Blocks, and time-of-day filters for enhanced setups.
