Potential benefits of extended hours trading
Access
Extended hours trading provides additional access, flexibility, and convenience for you to place trades outside of regular market hours.
Ability to react to news events
Many companies release earnings after the close of the regular session. After-hours traders can immediately place trades to manage their positions without having to wait until the next day's open, potentially missing meaningful price swings.
Potential risks of extended hours trading
Variable or lower liquidity
Because generally fewer shares trade after hours, there can be wide spreads between the bid (the highest price offered by all buyers) and the ask (the lowest price offered by all sellers). Some stocks may simply not trade after hours. In an overnight trading session, low liquidity or volume spikes may occur in either direction.
Uncertain prices
In the regular session, the quotes you see are consolidated and represent the best available prices across all trading venues. In extended hours trading sessions, you may only see prices from one venue, and these may not reflect the prices displayed in other electronic trading systems for the same security. There may also be one or more foreign markets opening or closing at any time during the session, which can have a short-term influence on pricing.
Lack of calculation of index value
For trades of certain index-based products, the underlying index values are not calculated by the broader market in the extended hours trading sessions.

Regular market hours trading sessions
The quotes you receive are consolidated and represent the best available prices across all trading venues. Market makers work to ensure fair market pricing so that customers get the best available buy or sell prices.

Pre-market, after-hours, and overnight trading sessions
Quotes and fills are not consolidated and represent the current prices available through the market. As a participant in the extended hours trading network, the market may also offer access to prices available in other participating markets but not necessarily all venues open for extended hours trading. Best execution is not guaranteed.

Finding extended hours quotes
It's important to note that an extended hours quote is different from a regular market quote. One significant difference is that there is currently no accurate trade volume available for extended hours trading on Schwab.com. Extended hours quotes reflect the best bid and ask orders currently available.
On Schwab.com, an extended hours quote can be accessed by clients using the Quick Quote feature that appears at the bottom of the page while logged in.
In thinkorswim, the last trade price is not displayed for an EXTO session, but mark, bid, ask, size, and level-2 quotes are displayed.
You can view and monitor the securities eligible for overnight trading in thinkorswim using Watchlist. Open the Watchlist menu, select "Public," then select "24 Hour Trading" to load the symbol list.
Frequently asked questions about extended hours trading
Because of limited trading activity in the extended hours, the difference, or spread, between available buy and sell orders is likely to be greater than during regular market hours. Higher spreads often result in more volatile prices. But remember, when you place an extended hours limit order, although there is no guarantee your order will be filled, you are ensured your limit order price or better if your order is executed. Trading after normal market hours comes with unique and additional risks, such as lower liquidity and higher price volatility. Your order may only be partially executed or not at all.
Currently, most listed securities are available for extended hours trading through Schwab. However, during any given extended hours session, certain securities may not trade due to a lack of trading interest.
The overnight trading session in thinkorswim is limited to a select number of securities. You can view and monitor the securities eligible for overnight trading in thinkorswim using Watchlist. Open the Watchlist menu, select "Public," then select "24 Hour Trading" to load the symbol list.
Both limited trading activity and orders placed ahead of yours may reduce the likelihood of your order being filled. Remember, extended hours orders are only executed when there is a matching buy or sell order in the system. If there is no matching buy or sell order at your limit order price, your order will not be executed. It's important to note that orders filled in an overnight trading session will be immediately visible in thinkorswim, but you may see a delay in viewing them in your Schwab.com transaction history.
Yes, the extended hours session functions independently from the regular market session. Orders for the regular market can be placed anytime before, during, or after the extended hours sessions. Clients should select the appropriate order timing based on which trading session they want.
Extended hours trading sessions are completely independent from the regular trading sessions, and you must specify which type of trading session (regular or extended) you intend for your order.
Equity orders placed during regular hours using "Day + Extended" on Schwab.com will carry over into that day's extended hours session. Stop orders will not be eligible for execution during an extended hours session.
Extended hours orders must be placed during an extended hours trading session on Schwab.com, Schwab Mobile, thinkorswim, or by calling 800-435-4000 and asking for an extended hours trading representative.
The overnight trading session is available exclusively on thinkorswim trading platforms. Log in to thinkorswim and select EXT (pre-market and after-market) or EXTO (extended overnight trading) to place an overnight trading session order. Only select securities qualify for an extended hours overnight session. Please make sure to specify EXT or EXTO when placing the order.
To view all securities eligible for overnight trading, open the Watchlist menu, select "Public," then select "24 Hour Trading" to load the symbol list.
