+"""DC01 — Donchian Channel Breakout con filtri.
+
+Trend-following classico: quando il prezzo rompe il massimo/minimo degli
+ultimi N periodi, entra nella direzione del breakout.
+
+Completamente diverso dallo squeeze (che usa Bollinger/Keltner).
+Donchian cattura breakout di RANGE, non di VOLATILITÀ.
+
+IN:
+    - OHLCV DataFrame
+    - Parametri: channel_period, volume_filter, atr_stop, trend_filter
+
+OUT:
+    - Signal al breakout del canale Donchian
+    - BacktestResult
+
+Logica:
+    1. Donchian upper = max(high, N periodi), lower = min(low, N periodi)
+    2. Close > upper → LONG (breakout rialzista)
+    3. Close < lower → SHORT (breakout ribassista)
+    4. Filtri: volume, trend EMA, ATR minimo
