Smart Order 算法单合集
本文介绍 Smart Order 系列算法单的适用场景。
位置：下单板 → Smart Order
⚠️ 风险提示：除服务器单之外，无限易的算法皆为本地算法单，依赖行情或成交回报触发。若因网络延迟、断线、软件关闭等原因导致算法无法正常运行，无限易不承担相关责任。
功能介绍
Smart Order 算法单是本地预埋单，主要分为价格算法、时间算法和拆单算法。在下单板设置参数并开启 Smart Order 后下单，即可生成对应算法单。
使用前请注意：
- 算法单委托在本地运行。软件关闭后，算法不会继续执行，也不会自动保存记录；下次打开软件时不会显示历史记录。
- 下单后，可在算法列表 → Smart Order 窗口管理算法单。
- 执行中或已暂停的算法单可手动保存：右键算法单，选择储存为任务下单。
- 也可在 定时管家 窗口设置自动保存。下次导入文件后可继续执行，详见 任务下单说明。
- 执行过程中如出现 错单（如资金不足、不在交易时间等）或 手动撤单，算法将自动终止。
价格算法
价格算法以行情价格作为触发条件。点击功能名称可查看详细说明。
| 功能名称 | 使用场景 | 触发参考价1 | 委托价 |
|---|---|---|---|
| 价格触发 | 行情达到目标后自动委托，算法自动判断触发条件2。 | 自定价格类型3 | 自定价格类型 ± 超价 |
| 大于小于 | 行情达到目标后自动委托，需手动设置触发条件2，适用于盘前场景。 | 自定价格类型3 | 自定价格类型3 ± 超价 |
| 二择一 | 同方向挂出 2 笔不同价格的预埋单；一笔触发后，另一笔自动失效。 | 最新价 | 自定价格 |
| 止盈止损 | 母单每笔成交后，自动生成 2 笔与母单买卖方向相反的二择一子单。 | 最新价 | 母单成交价 ± Tick |
| 两极回调 | 跟随行情自动调价，在行情反弹时委托，力争以更优价格入场。 | 最新价 | 根据行情生成 |
1. 触发参考价：行情满足触发条件时，用于判断触发的价格类型。 ↩
2. 触发条件：>、>=、<、<=，即触发参考价与委托价之间的比较关系。 ↩

Smart Order Algos
This section introduces the applicable scenarios for Smart Order Algos.
Location: Trade Board → Smart Order

⚠️ Risk Warning: Except for Server Trader, all InfiniTrader Algos run locally and are triggered by market quotes or fill reports. InfiniTrader assumes no liability if an Algo fails to run properly due to network latency, disconnection, software shutdown, or similar reasons.
Overview
Smart Order Algos are locally staged orders, mainly grouped into price-based Algos, time-based Algos, and order-splitting Algos. Set the parameters on the Trade Board, enable Smart Order, and place an order to create the corresponding Algo.
Before using Smart Order Algos, note the following:
- Algos run locally. If the software is closed, they stop running and are not saved automatically. No historical records will be available the next time the software is opened.
- After placing an order, manage the Algo in Algos → Smart Order.
- To save a running or paused Algo manually, right-click the Algo and select Save As Designated Order.
- You can also configure automatic saving in Time Master. Import the file next time to continue execution. For details, see Designated Trader.
- If an Algo encounters a Fail status, such as insufficient funds or orders outside trading hours, or if the order is manually canceled, the Algo ends automatically.
Price-Based Algos
Price-based Algos are triggered by market prices. Click a feature name to view details.
| Feature | Scenario | Trigger Reference Priceen-1 | Order Price |

| Stop | Automatically places an order when the market quote reaches the target. The Algo determines the trigger conditionen-2 automatically. | Custom Price Typeen-3 | Custom Price Type ± Pay up |
| Above/Below | Automatically places an order when the market quote reaches the target. The trigger conditionen-2 must be set manually. Designed for pre-market use. | Custom Price Typeen-3 | Custom Price Typeen-3 ± Pay up |
| OCO | Places two same-side staged orders at different prices. When one is triggered, the other becomes invalid automatically. | Last | Custom price |
| Bracket | After each parent order is filled, two opposite-side OCO child orders are created automatically. | Last | Parent order fill price ± Tick |
| Gain Best | Adjusts the order price with the market and places the order on a rebound, aiming for a better entry price. | Last | Generated based on market quotes |
