Environment Variables
| Variable | Default | Description |
|---|---|---|
T_TRADING_DEFAULT_STOCK |
sz000981 |
Default stock code |
T_TRADING_TOTAL_SHARES |

Edit scripts/config.py
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
