# 订单提交——新增触发单

订单通过 **WebSocket** 提交。

* **接口：**`wss://trade.qfex.com?api_key=YOUR_API_KEY`。
* **连接后必须在 1 分钟内完成身份认证。**

## 1. 身份认证

连接后立即发送：

```json theme={null}
{ "type": "auth", "params": { "hmac": { "public_key": "qfex_pub_xxxxx", "nonce": "c0ffee...", "unix_ts": 1760545414, "signature": "5f2e..." } } }
```

## 2. 新增订单

新增触发单与普通订单采用相同模式。指定的方向必须是触发后进入订单簿的最终订单方向。`TAKE_PROFIT` 和 `STOP_LOSS` 订单数量不得超过当前持仓；超过时可能导致本单被拒绝或其他触发单被取消。

```json theme={null}
{
  "type": "add_order",
  "params": {
    "symbol": "AAPL-USD",
    "side": "BUY",
    "order_type": "TAKE_PROFIT",
    "order_time_in_force": "GTC",
    "quantity": 1,
    "price": 200
  }
}
```

## 参数

| 字段 | 类型 | 必填 | 说明 |
| - | - | - | - |
| `symbol` | string | 是 | 交易品种，例如 `AAPL-USD`。 |
| `side` | enum | 是 | 订单方向，见 [OrderDirection](https://docs.qfex.com/cn/api-reference/enums.md#orderdirection)。 |
| `order_type` | enum | 是 | 订单类型，见 [OrderType](https://docs.qfex.com/cn/api-reference/enums.md#ordertype)。 |
| `order_time_in_force` | enum | 是 | 因历史兼容原因必须提供，但系统不会读取此值。 |
| `quantity` | number | 是 | 订单数量，须满足最小数量增量，但不受最小／最大数量限额约束。 |
| `price` | number | 是 | 订单触发价格。 |

注意：

* 最小价格增量、最小数量增量及订单数量上下限因品种而异，请参阅参考数据 API。
* 参数无效时，订单可能以 [OrderStatus](https://docs.qfex.com/cn/api-reference/enums.md#orderstatus) 中的状态码被拒绝。

## 响应示例

下单后，您会收到状态为 `ACK` 的 `order_response`：

```json theme={null}
{
  "order_response": {
    "order_id": "5b309929-206f-40ec-804d-cbe46e81afc1",
    "symbol": "AAPL-USD",
    "status": "ACK",
    "quantity": 1.0,
    "price": 200.0,
    "take_profit": 0.0,
    "stop_loss": 0.0,
    "side": "BUY",
    "type": "TAKE_PROFIT",
    "time_in_force": "GTC",
    "user_id": "0020ce8e-eaee-480e-8d7f-b9241d756ee5",
    "client_order_id": "",
    "quantity_remaining": 1.0
  }
}
```
