# ENGINEERING_SPEC — ECR-008 chart_tv 拆分
**ECR:** ECR-008
**Level:** L3 · 行为冻结
**Date:** 2026-08-07
## Goal
物理拆分主站 Lightweight Charts 绘制单体,不改变可见行为。
## Module map
| File | Responsibility |
|------|----------------|
| `chart_tv_lifecycle.js` | `disposeTradingViewCharts`cleanup 数组与 chart.remove |
| `chart_tv_shell.js` | `chartTvBuildShell(ctx)`:容器、createChart、K 线主系列 |
| `chart_tv_indicators.js` | `chartTvRenderIndicators(ctx)`:成交量 / ATR / ChanMACD |
| `chart_tv_chan.js` | `chartTvRenderChan(ctx)`:笔 / 线段 / 中枢(含未完成与 BI) |
| `chart_tv_overlays.js` | `chartTvRenderOverlays(ctx)`:结构区、威科夫、BSP/分型、布林等 |
| `chart_tv_finalize.js` | `chartTvFinalize(ctx)`:时间轴同步、bindSync、视图恢复、tooltip |
| `chart_tv.js` | `initTradingView`:组 ctx → 顺序调用上述步骤 |
## Context object
`ctx` 至少携带:`symbol``timeframe``symbolConfig`、周期开关、`candles`、各 chart/container、`showMacd`。全局 `currentData` / `tvWidget` 仍按现网约定使用。
## HTML load order
`lifecycle → shell → indicators → chan → overlays → finalize → chart_tv.js → chart_sync.js → …`
## Tests
1. `node --check` 各新文件 + 门面
2. 人工:首屏、自动刷新、威科夫开关、三周期笔段中枢、Cycle Summary
## Out of scope
Live 验证批跑、威科夫算法调参、analyze JSON 快照、`chart_sync` 大改。
