Gaspard98 - Donchian Channel - Trend Colored - Highs / Lows

> **Donchian Channel — Trend-Colored - Highs / Lows**
>
> This indicator plots a classic **Donchian Channel** (highest high / lowest low over *N* bars) and dynamically colors it based on the **current market structure** — bullish or bearish — making trend direction instantly readable at a glance.
>
> ---
>
> **How it works**
>
> The channel is drawn using:
> - **Upper band** — highest `high` over the chosen period
> - **Lower band** — lowest `low` over the chosen period
> - **Median line** — midpoint of the two bands
>
> Trend state is updated on every bar:
> - A **new swing high** (upper band expanding) flips the state to **bullish** → channel turns green
> - A **new swing low** (lower band expanding) flips the state to **bearish** → channel turns red
> - Bearish signals take **priority** over bullish signals on the same bar
>

> **Settings**
