# Weekend Stock Trading

#### Overview

Backpack offers weekend trading for select US equities through native spot orderbooks while traditional US exchanges are closed.

During regular US trading sessions, Backpack routes spot equities orders to traditional US exchanges. This includes the supported weekday sessions: pre-market, regular market, after-hours, and overnight trading.

Weekend trading uses a different liquidity model. When the weekend session is active, orders for supported stocks are routed to Backpack’s native weekend orderbooks, where liquidity is provided by market makers.

The security being traded does not change. It is not a futures contract, nor a synthetic instrument. A share bought or sold during the weekend session is the same real US security that users trade during the week. The difference is the source of liquidity. A user can buy a stock over the weekend, and sell it on Monday through the traditional brokerage flow once US markets open.

#### How weekend trading works

The weekend session normally runs from Friday 8:00 PM ET to Sunday 8:00 PM ET.

This starts after the Friday after-hours session ends and continues until the Sunday overnight session begins.

During this window:

* Supported spot equities are traded on Backpack-native orderbooks.
* Orders are matched against liquidity available on those orderbooks.
* Orders are not routed to traditional US exchanges while those exchanges are closed.
* Shares bought or sold are the same US securities traded during weekday sessions.
* Fractional share trading is available.

When the Sunday overnight session begins, routing transitions back to Backpack’s standard US equities flow.

#### Holidays

Weekend trading may also apply when traditional US exchanges are closed for a market holiday.

For example, if US exchanges are closed on a Friday or Monday, supported equities may continue trading through Backpack’s native orderbook model while traditional exchange routing is unavailable.

Note: Liquidity during weekend and holiday sessions may be thinner than during regular US market hours. Spreads may be wider, and prices may move differently while traditional US exchanges are closed.
