## Understanding the Display

The EA shows real-time metrics on the chart:

```
=== D-Basket EA Risk Monitor ===
Status: NORMAL
Net P/L: $125.50 (1.3%)
Daily P/L: $45.20
Drawdown: 3.2% (Max: 5.8%)
Baskets: 12 | Win Rate: 75.0%
Consecutive Losses: 0
```

### Status Indicators

- **NORMAL**: Trading allowed, all systems operational
- **WARNING**: Risk levels elevated, warnings logged
- **HALTED**: Circuit breaker tripped, trading stopped

---

## Common Scenarios

### Scenario 1: EA Opens a Basket

**What happens**:
1. Z-score exceeds entry threshold (e.g., -2.7)
2. All 8 filters pass
3. EA opens 3 positions simultaneously:
   - AUDNZD: BUY 0.01 lots
   - AUDCAD: SELL 0.01 lots
   - NZDCAD: BUY 0.01 lots

**What to check**:
- All 3 positions opened successfully
- Magic number matches on all positions
- Comment shows basket ID (e.g., "DBasket_1")

### Scenario 2: EA Closes a Basket

**What happens**:
1. Z-score returns to exit threshold (e.g., -0.3)
2. EA closes all 3 positions
3. P&L is recorded and metrics updated

**What to check**:
- All 3 positions closed
- Win/loss recorded correctly
- Metrics updated on chart

### Scenario 3: Circuit Breaker Trips

**What happens**:
1. Drawdown reaches 15% (or configured limit)
2. EA status changes to "HALTED"
3. No new baskets will open
4. Existing basket may be closed (emergency exit)

**What to do**:
- Review what caused the drawdown
- Check if parameters need adjustment
- Manually reset circuit breaker if appropriate
- Consider reducing risk parameters

---

## Troubleshooting

### EA Not Opening Trades

**Check**:
1. Circuit breaker status (should be NORMAL)
2. Current z-score (use visual mode to see)
3. Correlation level (must be > min threshold)
4. Spreads (must be < max threshold)
5. Trading hours (must be within configured window)
6. Logs for filter rejection reasons

### Partial Basket Opened

**What happened**:
- One or two legs opened, but not all three
- EA automatically rolled back (closed opened positions)

**Check**:
- Logs for error messages
- Broker execution quality
- Margin availability
- Symbol tradability

### High Drawdown

**Actions**:
1. Stop EA immediately
2. Review recent trades
3. Check if correlation broke down
4. Consider more conservative parameters:
   - Increase entry z-score (e.g., 3.0)
   - Increase min correlation (e.g., 0.80)
   - Reduce lot size
   - Lower max drawdown limit

## Parameter Optimization

### Optimization Ranges

Use Strategy Tester's optimization feature:

| Parameter | Min | Max | Step |
|-----------|-----|-----|------|
| Entry Z-Score | 2.0 | 3.5 | 0.25 |
| Exit Z-Score | 0.3 | 1.0 | 0.1 |
| Min Correlation | 0.70 | 0.85 | 0.05 |
| Lookback Period | 150 | 350 | 50 |

### Optimization Criterion

The EA's `OnTester()` function returns a custom score:

```
score = (profit / drawdown) × profit_factor × win_rate
```

This prioritizes:
- Risk-adjusted returns
- Consistent profitability
- High win rate

---

## Risk Management

### Circuit Breaker Triggers

| Condition | Warning | Trip |
|-----------|---------|------|
| Drawdown | 8% | 15% |
| Daily Loss | - | $100 or 5% |
| Margin Level | 500% | 200% |
| Consecutive Losses | - | 6 |

### Manual Intervention

**When to intervene**:
- Circuit breaker trips repeatedly
- Win rate drops below 50%
- Correlation between pairs breaks down
- Broker execution quality degrades

**How to intervene**:
1. Stop EA
2. Close any open baskets manually
3. Review parameters
4. Restart with adjusted settings

---

## Best Practices

### 1. Start Small
- Begin with minimum lot size (0.01)
- Test on demo account for 1+ month
- Gradually increase lot size after validation

### 2. Monitor Daily
- Check circuit breaker status
- Review daily P&L
- Verify correlation remains stable
- Check for error logs

### 3. Regular Optimization
- Reoptimize parameters quarterly
- Use walk-forward analysis
- Compare live results to backtest

### 4. Broker Selection
- Choose broker with tight spreads
- Ensure hedging is allowed
- Verify fast execution (< 500ms)
- Check commission structure
