Backpack Securities Trading Hours & Fees

One of the biggest advantages of Backpack Securities is around-the-clock accessibility. Select supported stocks trade 24/7, including weekends and U.S. market holidays, while all other listed stocks trade across four U.S. market sessions running nearly around the clock, Sunday 8:00pm through Friday 8:00pm ET. 

Trading hours

All times in this section are U.S. Eastern Time (ET).

• Select supported stocks trade continuously 24/7, including weekends and U.S. market holidays.
• All other listed stocks trade across four weekday sessions, running from Sunday 8:00pm ET through Friday 8:00pm ET, and are paused on weekends and U.S. market holidays.

Weekend and holiday trading currently supports SPCX, MU, SNDK, and SKHY, with additional tickers added over time. For how continuous 24/7 trading works, see Can You Trade U.S. Stocks on the Weekend? How 24/7 Equities Trading Works on Backpack.

Reading the market status indicator

Every Backpack Securities page shows a market status indicator a small colored dot with a label that tells you which session is live. When a session is active, the dot pulses. Hover over it for a tooltip showing each session's range, with Eastern Time hours automatically converted to your local timezone. When the market is closed, it also shows a countdown until the next session.

Whole vs. fractional shares

Fractional shares are available during regular hours (9:30am–4:00pm ET, Monday–Friday) for all listed stocks, and during weekend and holiday sessions for supported stocks. During overnight, pre-market, and after-hours, you can trade whole shares only, with a one-share minimum per order.

If you enter a fractional quantity during a whole-shares-only session, the order form will prompt you to round to a whole number or wait for a fractional-enabled session to reopen. Quotes may be wider outside regular U.S. market hours because there is usually less liquidity overnight, pre-market, after-hours, and during weekend and holiday sessions. This is market behavior, not a separate Backpack commission or platform fee.

Funding & fees

Stock and ETF trades use the same Backpack account balance you use elsewhere on the platform. When you buy, the order is funded from your available balance. When you sell, proceeds return to your available balance.

Funding a buy

You can fund stock and ETF buys with eligible USD or USDC. The order form shows your available balance on the Available row before you preview a trade.

On the buy side, you can also use quick-amount pills, i.e. 25%, 50%, 75%, and Max to fill in a portion of your available balance automatically. If your USD is in Backpack’s lending pool, eligible lent USD is included in your available balance and can be pulled back automatically when needed to fund a stock or ETF buy. 

No automatic margin on stock buys

Backpack does not automatically borrow funds to complete a stock or ETF purchase, and there is no margin toggle on the stock order form. Stock and ETF buys use funds you already have available, including eligible USD, USDC, and eligible lent USD.
If you want to use borrowed USD, you need to borrow it manually through Backpack’s lend/borrow feature before placing the stock or ETF order. The usual borrowing rules apply to that loan, but the stock or ETF position itself is not traded on margin.

Stocks and ETFs cannot be used as collateral

Stock and ETF balances cannot be used as collateral for other positions right now. They do not count toward margin and cannot back a perp or other borrowed position. That also means a stock or ETF balance cannot be force-liquidated to cover another position.

Selling a position

When you sell a stock or ETF, proceeds return to your available Backpack balance. During public beta, selling within Backpack is the way to exit a stock or ETF position.

Stocks and ETFs cannot yet be transferred to an external wallet, broker, or platform.

Fees 

Stock and ETF trading is commission-free. Backpack does not charge a separate commission or platform fee on stock and ETF trades.

At the Preview step, you’ll see the Estimated Price, Subtotal, and Total before you confirm. The previewed quote is the price you choose to accept.

Spreads, taxes, regulatory fees, third-party charges, or future fees may still apply.

Minimum order size

During regular U.S. market hours, and during weekend and holiday sessions for supported stocks, you can trade fractional shares down to 0.01 share, in 0.01-share increments.

During overnight, pre-market, and after-hours sessions, the minimum is 1 whole share.

Every order also needs to be worth at least $1.

Why pricing changes outside regular hours

Backpack Securities is quote-based: when you preview an order, you see a live quote reflecting current market conditions. Outside regular hours there's less liquidity, so quotes are naturally wider, especially overnight and during weekend and holiday sessions. This isn't a Backpack fee; it reflects the state of the underlying market. For the tightest pricing, trade during regular hours, when liquidity is deepest.

Order minimums
