## 调用示例

### 批量接口（推荐）

```bash
# BTC：RSI + MACD + BOLL + KDJ
curl -sS "${AUTH[@]}" -X POST "$BASE/api/v2/crypto/indicators/batch" -d '{
  "exchange": "binance",
  "symbol": "BTCUSDT",
  "interval": "1d",
  "limit": 100,
  "indicators": [
    {"type": "rsi", "params": [14]},
    {"type": "macd", "params": [12, 26, 9]},
    {"type": "boll", "params": [20, 2.0]},
    {"type": "kdj", "params": [9, 3, 3]}
  ]
}'

# ETH：4h 级别 MACD + EMA
curl -sS "${AUTH[@]}" -X POST "$BASE/api/v2/crypto/indicators/batch" -d '{
  "exchange": "binance",
  "symbol": "ETHUSDT",
  "interval": "4h",
  "limit": 200,
  "indicators": [
    {"type": "macd", "params": [12, 26, 9]},
    {"type": "ema", "params": [20]}
  ]
}'
```

### 单指标接口

```bash
# BTC RSI
curl -sS "${AUTH[@]}" "$BASE/api/v2/crypto/indicators/rsi?exchange=binance&symbol=BTCUSDT&interval=1d&period=14&limit=100"

# ETH MACD
curl -sS "${AUTH[@]}" "$BASE/api/v2/crypto/indicators/macd?exchange=binance&symbol=ETHUSDT&interval=1d&fast_period=12&slow_period=26&signal_period=9&limit=100"

# SOL BOLL
curl -sS "${AUTH[@]}" "$BASE/api/v2/crypto/indicators/boll?exchange=binance&symbol=SOLUSDT&interval=1d&period=20&nbdev=2.0&limit=100"

# 无参数指标：OBV
curl -sS "${AUTH[@]}" "$BASE/api/v2/crypto/indicators/obv?exchange=binance&symbol=BTCUSDT&interval=1d&limit=100"
```

## 错误排查

| 错误 | 原因 | 修复 |
|------|------|------|
| 400 (缺 exchange) | `exchange` 必填 | 加上 `exchange`: `binance` |
| 400 (日期格式) | 用了 `YYYYMMDD` | 指标端点用 `YYYY-MM-DD` |
| 404 | 指标类型拼写错误 | 小写：`rsi`, `macd`, `boll` |
| 数据不足 | K线数量不够计算指标 | 增大 `limit` |
