3. Lock-up Period Monitor / 限售期監控

## 限售期規則與影響

### 各板塊限售規則

| 板塊 | 戰略投資者 | 網下投資者 | 原股東 |
|-----|-----------|-----------|--------|
| 主機板 | 12個月 | 6個月 | 12個月（大股東）|
| 科創板 | 12個月 | 6個月 | 12個月（大股東）|
| 創業板 | 12個月 | 6個月 | 12個月（大股東）|
| 北交所 | 6個月 | 12個月 | 大股東12個月 |

### 解禁壓力測算
```python
def calculate_unlock_pressure(stock_code: str, unlock_date: str) -> dict:
    """
    計算解禁壓力
    """
    total_shares = 1000000000  # 總股本
    locked_shares = 300000000  # 限售股
    avg_cost = 25  # 平均成本

    market_price = 45  # 當前股價

    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)

Disclaimer

IPO investment involves substantial risk. IPO performance in the past does not indicate future results. New issues may list below issue price (破發). Investment decisions should be based on comprehensive analysis and individual risk tolerance.

這個打新策略工具質量中上水平，優勢在於分析框架完整、覆蓋打新全流程（選股-申購-上市-限售期），觸發詞豐富容易喚起。不足是內容偏理論化，實際可用的資料和分析功能有限，缺少即時行情支援和歷史策略驗證。適合作為打新入門學習參考，但真要用於投資決策還需要結合其他專業工具。風險提示部分過於簡略，對新手投資者不太友好。
