# 周末股票交易

## **概述**

Backpack 通过原生现货订单簿，在美国传统交易所休市期间，为精选美股提供周末交易服务。

在美国常规交易时段，Backpack 将现货股票订单路由至传统美国交易所，涵盖支持的工作日时段：盘前、常规、盘后及夜间交易。

周末交易采用不同的流动性模型。当周末时段激活时，支持股票的订单将路由至 Backpack 原生周末订单簿，由做市商提供流动性。

交易的证券本身不会改变——既非期货合约，也非合成产品。周末时段买入或卖出的股票，与用户在工作日交易的真实美国证券完全相同，区别仅在于流动性来源。用户可以在周末买入股票，并在周一美国市场开盘后通过传统经纪流程将其卖出。

## **周末交易的运作方式**

周末时段通常为美国东部时间周五晚上 8:00 至周日晚上 8:00。

该时段在周五盘后时段结束后开启，持续至周日夜间时段开始。

在此期间：

* 支持的现货股票在 Backpack 原生订单簿上交易。
* 订单在订单簿的可用流动性中撮合成交。
* 美国交易所休市期间，订单不会路由至传统交易所。
* 买入或卖出的股份与工作日时段交易的美国证券相同。
* 支持碎股交易。

周日夜间时段开始后，路由将切换回 Backpack 的标准美股流程。

## **节假日**

当美国传统交易所因市场假日休市时，周末交易规则同样适用。

例如，若美国交易所在周五或周一休市，支持的股票可继续通过 Backpack 原生订单簿模型交易，而无需传统交易所路由。

**注意：**周末及节假日时段的流动性可能低于美国常规市场时段，价差可能更宽，价格走势也可能与传统美国交易所开市期间有所不同。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.backpack.exchange/support-docs/cn/zheng-quan/zhou-mo-gu-piao-jiao-yi.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
