# [INT-11] Candlestick · 캔들스틱

> AI 붙여넣기 카드. 갤러리 런타임(`main.js`)이 아니라 이 파일을 가져와라.

## 언제 가져가나
금융 차트의 표준 — OHLC 캔들 + 거래량 + 이동평균선.

**응용** 주가·코인 시세, 일일 변동성 추이, A/B 분포 일별.

## 데이터 모양
- family: `financial`
- dataShape: ohlc candlestick with volume
- tasks: explore data, monitor change, drill into structure, show price range
- tags: interactive, live, exploration, candlestick, ohlc, 캔들스틱


## 의존
echarts@5 · load `low` · library `ECharts`

## 붙여넣는 법
1. echarts 5.x 로드 (GL이면 echarts-gl도)
2. 컨테이너 id를 원본 id와 맞추거나 `document.getElementById` 한 줄만 바꾼다
3. `T`, `reg`, `cssv` 가 필요하면 갤러리 테마 스텁을 함께 가져간다

```js
const T = {
  "bg": "transparent",
  "fg": "#ece8f5",
  "sub": "#a59bbd",
  "grid": "rgba(255,255,255,.08)",
  "gold": "#e8c069",
  "royal": "#6b8cff",
  "rose": "#e07a9f",
  "teal": "#6dd2c4",
  "plum": "#b487e8"
};
const cssv = (n, fb) => (getComputedStyle(document.documentElement).getPropertyValue(n).trim() || fb);
const isDark = () => document.documentElement.getAttribute('data-theme') !== 'light';
const charts = [];
const reg = (id, opt) => {
  const dom = document.getElementById(id); if (!dom) return;
  const c = echarts.init(dom, null, {renderer:'canvas'});
  c.setOption(opt);
  charts.push(c);
  return c;
};
const factory = function(){
  const dom = document.getElementById('c-candle'); if(!dom) return;
  const c = echarts.init(dom);
  const dates = [], k = [], vol = [];
  let p = 100;
  for(let i=0;i<60;i++){
    const o = p, ch = (Math.random()-.48)*4;
    const cl = +(o+ch).toFixed(2);
    const hi = +Math.max(o,cl) + Math.random()*1.2;
    const lo = +Math.min(o,cl) - Math.random()*1.2;
    k.push([o, cl, +lo.toFixed(2), +hi.toFixed(2)]);
    vol.push(Math.round(60+Math.random()*140));
    p = cl;
    const d = new Date(2026,2,1+i); dates.push((d.getMonth()+1)+'.'+d.getDate());
  }
  // MA(5)
  const ma = k.map((_,i)=> i<4 ? '-' : +(k.slice(i-4,i+1).reduce((s,x)=>s+x[1],0)/5).toFixed(2));
  c.setOption({
