+# useLightweightChart
+
+**路径**：`src/composables/useLightweightChart.ts`
+
+## 功能用途
+
+[TradingView Lightweight Charts](https://tradingview.github.io/lightweight-charts/) 工具函数，用于将项目内 `[timestamp_ms, value][]` 格式转为图表所需格式，并提供创建折线/面积图的便捷方法。
+
+## 核心能力
+
+- `toLwcData`：将 `[timestamp_ms, value][]` 转为 `{ time: UTCTimestamp, value: number }[]`，输入为毫秒（>=1e12）时自动除以 1000 转为秒，按时间升序排序并去重（同时间戳保留最新价格），时间轴显示用户当地时间
+- `toLwcPoint`：将单点 `[timestamp_ms, value]` 转为 `{ time, value }`，用于 `series.update()` 增量更新
+- `createLineChart`：创建基础折线图实例（`attributionLogo: false` 隐藏 TradingView 图标）
+- `addLineSeries`：添加折线系列（支持 percent/price 格式）
+- `addAreaSeries`：添加面积系列（带渐变）
+
+## 使用方式
+
+```typescript
+import { toLwcData, toLwcPoint, createLineChart, addLineSeries } from '@/composables/useLightweightChart'
+
+const points: [number, number][] = [[Date.now() - 3600000, 50], [Date.now(), 55]]
+const lwcData = toLwcData(points)
+
+const chart = createLineChart(containerEl, { width: 400, height: 320 })
+const series = addLineSeries(chart, { color: '#2563eb', priceFormat: { type: 'percent', precision: 1 } })
+series.setData(lwcData)
+
+// 实时追加/更新单点时，使用 update() 替代 setData() 以获得过渡动画
+series.update(toLwcPoint([Date.now(), 52]))
+```
+
+## 扩展方式
+
+- 新增图表类型：参考 `addAreaSeries` 使用 `AreaSeries`、`CandlestickSeries` 等
+- 自定义主题：修改 `createLineChart` 的 `layout`、`grid`、`rightPriceScale` 等配置

 - 交易：`TradeComponent`，传入 `market`、`initialOption`、`positions`（持仓数据）
