3. Lock-up Period Monitor / 限售期监控

## 限售期规则与影响

### 各板块限售规则

| 板块 | 战略投资者 | 网下投资者 | 原股东 |
|-----|-----------|-----------|--------|
| 主板 | 12个月 | 6个月 | 12个月（大股东）|
| 科创板 | 12个月 | 6个月 | 12个月（大股东）|
| 创业板 | 12个月 | 6个月 | 12个月（大股东）|
| 北交所 | 6个月 | 12个月 | 大股东12个月 |

### 解禁压力测算
```python
def calculate_unlock_pressure(stock_code: str, unlock_date: str) -> dict:
    """
    计算解禁压力
    """
    total_shares = 1000000000  # 总股本
    locked_shares = 300000000  # 限售股
    avg_cost = 25  # 平均成本
    
    market_price = 45  # 当前股价
    
    unlock_ratio = locked_shares / total_shares * 100
    profit_ratio = (market_price - avg_cost) / avg_cost * 100
    
    if profit_ratio > 100:
        pressure_level = "高"
    elif profit_ratio > 30:
        pressure_level = "中"
    else:
        pressure_level = "低"
    
    return {
        "unlock_date": unlock_date,
        "locked_shares": locked_shares,
        "unlock_ratio": round(unlock_ratio, 2),
        "avg_cost": avg_cost,
        "current_price": market_price,
        "profit_ratio": round(profit_ratio, 2),
        "pressure_level": pressure_level,
        "estimated_selling_volume": round(locked_shares * 0.3, 0)
