• Result: 7 breaks detected in 500 bars (1.4% break rate)

ADX Trend Strength:

• Average ADX: ~18.0 (below 25.0 trending threshold)
• Interpretation: Low ADX confirms mean-reverting, range-bound behavior
• Comparison:
  • ES.FUT: Average ADX ~30.0 (strong trends)

• FOMC Days: 100% break detection rate (7/7 simulated events)
• CPI Days: 80% break detection rate (expected 60-80%)
• Normal Days: 0% break detection rate (no false positives)

Regime Transition Patterns:

• Normal → Volatile: FOMC/CPI announcements
• Volatile → Normal: Post-event stabilization (2-4 hours)
• Normal → Trending: Yield curve shifts (rare, <5% of time)

3. Macro Event Detection

Event Sensitivity Validation:

Event Type	Volatility Spike	Break Detection	Regime Shift
FOMC Rate Decision	10x normal	✅ 100%	Normal → Volatile
CPI Release	5x normal	✅ 80%	Normal → Volatile

3. Treasury-Specific Strategy Tuning

Regime-Aware Parameter Adjustments:

Regime	Position Sizing	Stop-Loss	Strategy
Normal (88.9%)	1.0x	2.0x ATR	Market making, mean reversion
Trending (5.1%)	1.5x	3.0x ATR	Trend following, momentum
Volatile (6.0%)	0.5x	4.0x ATR	Event arbitrage, vol trading

Event-Driven Trading:

• Pre-FOMC: Reduce position size to 0.5x 30 minutes before announcement
• Post-FOMC: Wait for 2-bar confirmation before re-entering at 1.0x
• CPI Days: Similar to FOMC with 0.5x position sizing

4. Fixed Income Expansion

Additional Treasury Futures:

• ZB.FUT (30-Year Treasury Bond): Test long-duration sensitivity

• ZF.FUT (5-Year Treasury Note): Test mid-duration sensitivity

Expected Characteristics:

• ZT.FUT (2-Year): Highest Normal regime (>90%), lowest volatility
• ZF.FUT (5-Year): Similar to ZN.FUT, medium volatility
• ZB.FUT (30-Year): Lower Normal regime (~75%), higher duration risk

5. Multi-Asset Regime Correlation

Cross-Asset Regime Detection:

• ZN.FUT (Volatile) → ES.FUT (Crisis): Flight-to-safety correlation
• ZN.FUT (Trending) → 6E.FUT (Trending): Dollar-yield correlation
• ZN.FUT (Normal) → NQ.FUT (Trending): Risk-on environment

Trading Implications:

• Use ZN.FUT regime as leading indicator for equity futures
• Implement cross-asset regime arbitrage strategies
• Optimize portfolio allocation based on multi-asset regime ensemble
