## 🔍 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

---

- [ ] 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](TECHNICAL_DOCUMENTATION.md) for understanding
- [ ] Optimize parameters
