   - Validates mean-reverting FX behavior

2. **Low Trending Frequency** ✅
   - 5.1% trending periods
   - Confirms lack of sustained directional moves in FX

3. **Moderate Volatility** ✅
   - 8.6% volatile periods
   - Typical for Euro/Dollar pair (stable G7 currencies)

4. **Structural Stability** ✅
   - 0 CUSUM breaks on 2024-01-02
   - Stable market conditions (no major news events)

5. **High Regime Persistence** ✅
   - 86.87% average stability
