IBKR Pro account holders have the widest time slot for extended-hours trading

Extended-hours trading happens outside standard market hours, covering both premarket and after-hours sessions. As a trader, it allows you to respond to news and events that unfold when regular markets are closed. The popularity of overnight trading surged in 2023 when several brokers, including Interactive Brokers, rolled out this feature.

Every trader with an Interactive Brokers account has access to after hours trading service. Depending on your IB account type, you will have different schedules available for after hours trading. IBKR Pro account holders have a wider time slot for extended-hours trading than those with an IBKR Lite account.

After hours trading schedules by IB account type
Account type Premarket trading start time After-hours trading start time After-hours trading end time
IBKR Pro accounts 4:00 AM EST (9:00 AM GMT+1) 4:00 PM EST (9:00 PM GMT+1) 8:00 PM EST (1:00 AM GMT+1)
IBKR Lite accounts 7:00 AM EST (12:00 PM GMT+1) 4:00 PM EST (9:00 PM GMT+1) 8:00 PM EST (1:00 AM GMT+1)

Interactive Brokers also offers an Overnight Trading feature for certain US stocks and ETFs. The service is active from 8:00 p.m. ET to 3:50 a.m. ET, Sunday through Friday. Trades made in this period are dated to the following trading day. Importantly, overnight trading aligns with the New York Stock Exchange (NYSE) holiday schedule. This means if the NYSE is closed on the following day, Interactive Brokers will not hold an overnight trading session the night before.

A word of caution: liquidity tends to significantly decrease during extended hours, which may lead to increased volatility. To boost liquidity, IB offers its own IBEOS Alternative Trading System (ATS) and is connected to the Blue Ocean ATS.

Set trading hours for each trade case-by-case or through global configuration settings

By default, when you place an order, it is executed during the standard trading hours. If you want your trades at IB executed outside regular market hours as well, you will need to change the Regular Trading Hours (RTH) setting. You can do this either on a case-by-case basis before placing a particular order, or by adjusting global configurations for all your orders.

IBKR TWS - case-by-case configuration

For individual orders on IB’s Trader Workstation (TWS), you can change the RTH setting by clicking the 'DAY' field in the order panel before placing the order. A drop-down menu will appear, where you can select 'Fill outside RTH.' There are other options as well, allowing you to align the execution of your order with your trading strategy.

IBKR TWS - global configuration

If you want after hours execution to apply to all your orders (where applicable), you can change the global settings in TWS by following these steps:

  • Select the File menu at the top of the main TWS screen, then choose Global Configuration.
  • Expand the Presets section by clicking the '+' next to it.
  • Select the product type (i.e. Stocks or ETFs) by clicking on it.
  • In the Primary Order section, ensure the Order Type is set to Limit Order (LMT). Note that this setting is not applicable if Market Order (MKT) or Stop Order (STP) is the default order type.
  • In the Timing section, check 'Allow order to be activated, triggered, or filled outside of regular trading hours'.
  • Click Apply, then OK to save these settings.

IBKR Mobile - case-by-case configuration

You can change both individual order settings and default RTH settings in IB's mobile applications for Android and iOS devices.

Here is how you can change the RTH settings for individual orders in the IB mobile app:

  • In the Mobile Order Ticket, there's a 'Time-in-force' line item for Android users. Tap the small arrow on the right to expand this section.
  • You'll find an 'Outside RTH' option with a toggle switch, which can be set to ON (to fill outside RTH) or OFF (to restrict to RTH).
  • You can also toggle 'Overnight Trading' on or off directly in the Order Ticket.

This feature is also available in the iOS version, where you can toggle 'Outside RTH' on or off in the Order Ticket.

IBKR Mobile - global configuration

Here is how you can adjust default RTH settings in the mobile app:

  • Access the menu (More) and select 'Setting'
  • From the list select 'Trading Settings'
  • Choose the product type for which you want to edit the Presets
  • Tap on 'Timing' and then toggle the 'Outside RTH' option on or off as per your requirement
  • To save your changes, simply tap the back button, and these settings will be updated in the Cloud.

Trade a wide range of assets outside market hours at IB without extra fees

Interactive Brokers clients can trade a diverse range of asset types during extended trading hours, including stocks, ETFs, and stock options. Clients outside the US can also trade CFDs (Contracts for Difference) outside regular hours. The service is free of charge, which is pretty sweet.

In addition to the extended trading hours, the Overnight Trading feature applies to over 10,000 US stocks and ETFs. Note that fractional trading is not available during these sessions.
