FX-Specific Validation

Currency Market Characteristics (6E.FUT)

1. Range-Bound Behavior ✅

   • 60.9% ranging regime (vs. 40% threshold)
   • 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
   • Prolonged regime durations (10.77 bars average)

Adaptive Strategy Implications for FX

1. Position Sizing: Higher leverage allowed (1.383x average) due to lower FX volatility
2. Stop-Loss Placement: Tighter stops viable (ranging markets mean-revert)
3. Regime Detection: CUSUM less effective for FX (fewer breaks), ADX + Bollinger Bands more important
4. Trading Strategy: Mean-reversion strategies preferred over trend-following for FX
