## 持仓数据格式

持仓存储在 `~/.clawdbot/etf_investor/positions.json`:
```json
[
  {
    "symbol": "SPY",
    "name": "S&P 500 ETF",
    "buy_price": 150.50,
    "quantity": 100,
    "buy_date": "2026-02-23",
    "current_price": 155.20,
    "last_updated": "2026-02-23T10:30:00Z"
  }
]
```

## 价格提醒数据格式

提醒存储在 `~/.clawdbot/etf_investor/alerts.json`:
```json
[
  {
    "symbol": "SPY",
    "target_price": 160.00,
    "condition": "price_up",
    "created_at": "2026-02-23T10:00:00Z",
    "triggered": false
  }
]
```

## 盈亏计算公式

- **持仓市值**: 当前价 × 数量
- **成本**: 买入价 × 数量
- **盈亏金额**: (当前价 - 买入价) × 数量
- **盈亏比例**: (当前价 - 买入价) / 买入价 × 100%

## 支持的代码格式

- **美股 ETF**: SPY, QQQ, VOO, VTI, IVV, IWM
- **国际 ETF**: EFA, VEA, VWO, VXUS
