## Configuration

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `T_TRADING_DEFAULT_STOCK` | `sz000981` | Default stock code |
| `T_TRADING_TOTAL_SHARES` | `1200` | Total share position |

### Edit `scripts/config.py`

```python
class Config:
    SUPPORT_LEVEL = 4.01      # Support price
    RESISTANCE_LEVEL = 4.72   # Resistance price
    MAX_POSITION_RATIO = 0.3  # Max 30% per trade
```

## Mathematical Models

### 1. Expected Value
```
E(T) = p × profit - (1-p) × loss
```
- If E(T) > 0: Worth trading
- If E(T) < 0: Avoid trading

### 2. Bayesian Update
```
p_new = α × p_recent + (1-α) × p_historical
```
- α = 0.7 (recent weight)
- Dynamically adjusts win rate

### 3. Kelly Criterion
```
f* = (p × b - q) / b
```
- b = profit/loss ratio
- Optimal position sizing

### 4. Value at Risk
```
VaR = z × σ × position_value
```
- 95% confidence: z = 1.645
- Maximum daily loss estimate
