🔍 Key Concepts

Three-Pair Correlation Strategy

The EA exploits the mathematical relationship:

AUDNZD ≈ AUDCAD / NZDCAD

When this relationship diverges (measured by z-score), the EA enters a hedged basket expecting mean reversion.

Basket Trading

A "basket" consists of 3 coordinated positions:

• AUDNZD - Reference leg
• AUDCAD - Hedge leg 1
• NZDCAD - Hedge leg 2

All 3 legs are opened/closed together as a single unit.

🆕 v2.0 Optimization Features

Cointegration Filter (ADF Test)

Only trades when spread is statistically proven to be mean-reverting (p < 0.05).

Half-Life Exit Timing

Calculates optimal holding time using Ornstein-Uhlenbeck process. Exits at 2× half-life or if spread diverges further.

ATR Position Sizing

Balances risk across all 3 legs using inverse volatility weighting. High-volatility pairs get smaller lots.

Circuit Breaker

Automatic risk control system that halts trading when:

• Drawdown exceeds 15%
• Daily loss exceeds limit
• Margin level drops below 200%
• 6 consecutive losses occur

⚠️ Critical Information

Hedging Account Required

This EA requires a hedging account. It will NOT work on netting accounts.

The EA validates this in OnInit() and will fail initialization if the account is not in hedging mode.

Broker Requirements

• ✅ Hedging account type
• ✅ All 3 symbols available (AUDCAD, NZDCAD, AUDNZD)
• ✅ Spreads < 3 pips per symbol
• ✅ Fast execution
• ✅ No hedging restrictions

---

🚀 Getting Started Checklist

• Read QUICK_START.md
• Install EA files to MT5
• Compile in MetaEditor (verify 0 errors)
• Configure broker symbol suffix (if needed)
• Choose EA version (v1.0 or v2.0)
• Run backtest on 1 year of data
• Review TECHNICAL_DOCUMENTATION.md for understanding
• Optimize parameters
• Deploy to demo account
• Monitor for 1+ month
• Review DEVELOPMENT_SUMMARY.md for context
