 It is strongly recommended to always provide a unique `client_request_id` for critical order submissions to prevent unintended duplicates.
 
+### Time-Condition Orders
+
+Pass `delayed_until` (Unix timestamp in seconds) to create a time-condition order. The order is not sent to the exchange right away: it stays in `DelayedNotReported` status and is submitted automatically when the time arrives. The time must be later than now and no more than 90 days ahead.
+
+Supported markets and order types:
+
+- HK stocks / warrants: `LO` / `ELO` / `MO` / `LIT` / `MIT`
+- US stocks / warrants / options: `LO` / `MO` / `LIT` / `MIT`
+- SG stocks: `LO` / `MO` / `LIT` / `MIT`
+- Crypto: `LO` / `MO`
+
+Use [Replace Order](./replace) to change the time (`delayed_until` set to a new time) or turn it into a regular order (`delayed_until` set to `1`). Order queries return the time in the `delayed_until` field.

 强烈建议在关键下单操作中始终提供唯一的 `client_request_id`，以防止意外的重复订单。
 
+## 时间条件单
+
+传入 `delayed_until`（Unix 时间戳，秒）即可提交时间条件单。订单不会立即报送交易所，而是以 `DelayedNotReported` 状态等待，到达指定时间后自动提交。该时间必须晚于当前时间且不超过 90 天。
+
+支持的市场与订单类型：
+
+- 港股正股 / 窝轮：`LO` / `ELO` / `MO` / `LIT` / `MIT`
+- 美股正股 / 窝轮 / 期权：`LO` / `MO` / `LIT` / `MIT`
+- 新加坡股票：`LO` / `MO` / `LIT` / `MIT`
+- 加密货币：`LO` / `MO`
+
+可通过[改单](./replace)修改提交时间（`delayed_until` 传新的时间），或转为普通订单（`delayed_until` 传 `1`）。订单查询接口通过 `delayed_until` 字段返回该时间。

 为了方便理解，我们下面以 Python 作为示例，介绍如何实现一些场景的下单操作。
