Double Donchian Channel + T3 MA (Dynamic Color)

This indicator combines a **Double Donchian Channel** with a **dynamic T3 Moving Average** to provide a clear view of market structure, volatility, and trend direction on a single chart. The **fast Donchian channel** tracks short-term price extremes, making it useful for identifying breakouts, pullbacks, and momentum shifts. The **slow Donchian channel** represents higher-timeframe structure and acts as a dynamic support and resistance zone, helping traders understand the broader trend context and avoid trading against dominant market pressure.

At the center of the system is the **T3 Moving Average**, a highly smoothed moving average designed to reduce noise while remaining responsive to trend changes. The T3 line **changes colour automatically based on its slope**: it turns **green when rising**, signaling bullish momentum, and **red when falling**, signaling bearish momentum. This colour change allows traders to visually identify trend direction and transitions without relying on lagging crossover signals.

When price trades above a rising (green) T3 and remains within or above the slow Donchian channel, market conditions favor continuation trades and long-side bias. Conversely, when price is below a falling (red) T3 and breaking or respecting the lower Donchian boundaries, bearish continuation setups are favored. Overall, this indicator is best suited for **trending and volatility-expanding markets**, and it works especially well when combined with volume-based tools or regime filters to avoid ranging conditions.
