In today’s global marketplace, financial news and market-moving events don’t adhere to traditional trading hours. Interactive Brokers (IBKR) has responded to this reality by developing one of the industry’s most comprehensive overnight trading services, providing traders with extended access to U.S. markets well beyond standard exchange hours.
IBKR’s overnight trading service enables clients to trade over 10,000 U.S.-listed stocks and ETFs during hours when most other retail platforms remain closed. The service operates from 8:00 PM ET to 3:50 AM ET, beginning Sunday evening and continuing through Friday morning. This expanded timeframe allows traders to respond to overnight developments, international market movements, and breaking news without waiting for the next day’s regular session.
For traders who maintain positions in U.S. equities, this extended access provides significant strategic advantages. It enables reaction to earnings announcements (which often occur after market close), overseas market developments, and geopolitical events that might otherwise require waiting hours before taking action.
To facilitate this extended trading window, IBKR has established a specialized market structure. The firm has partnered with Blue Ocean Technologies, a leading liquidity provider for overnight markets, while also leveraging its own internal liquidity pool called IBEOS. Together, these sources create a comprehensive overnight trading ecosystem.
Orders placed during overnight hours operate within what IBKR designates as an independent venue, separate from regular and traditional extended-hours trading. The platform combines internal and external liquidity sources to establish competitive pricing despite the reduced overall market participation during overnight hours.
IBKR’s SmartRouting technology plays a crucial role in this process, directing orders to the venue offering the best available price, whether that’s Blue Ocean or IBKR’s internal matching engine. This approach helps maintain execution quality during periods when liquidity might otherwise be fragmented or thin. Frequently Traders can get better prices than the limit.
Placing overnight trades through IBKR’s platforms follows a straightforward process, though traders should note certain limitations compared to regular hours. Currently, only Limit and Adaptive order types are supported during overnight sessions, providing price protection in potentially less liquid conditions.
When submitting orders, traders select from two time-in-force options: “OVERNIGHT” or “OVERNIGHT + DAY.” The former keeps orders active only during the overnight session (8:00 PM to 3:50 AM ET), while the latter extends the order’s life through the following regular trading day. Importantly, GTC (Good-Til-Cancelled) orders are not supported, meaning unfilled orders will be cancelled at sessions end rather than persisting indefinitely.
The order submission process mirrors IBKR’s standard interface, with traders selecting their symbol, quantity, order type, price, and time-in-force preference before transmitting. Once submitted, orders appear in the Activity panel with “OVERNIGHT” or “OVERNIGHT + DAY” displayed in the Destination column.
Traders should note that transactions executed between 8:00 PM and midnight ET carry the following day’s trade date, an important consideration for settlement and tax purposes. Additionally, while market data for overnight sessions is provided free of charge, traders should anticipate potentially wider spreads and lower overall volume compared to regular hours.
For investors seeking to capitalize on global market developments or simply requiring more flexible trading hours, IBKR’s overnight trading capability represents a significant expansion of market access, transforming U.S. equity trading from a limited daily window into a nearly continuous opportunity set throughout the business week.

On good till cancel order for overnight + day, will trailing stop limit order get cancelled if not activated ? Will it get cancelled after it has been activated but not filled ? Is there a dollar limit on overnight order?
Hi David, thank you for asking. While many active investors may only use Day orders, the GTC designation means that you can place orders and then forget about them for weeks, and even months at a time. When you use this order type, it will remain in force until it either fills or is otherwise cancelled.
Although GTC orders can be left in place for several months, they do not last forever. In fact, they will automatically be cancelled at the end of the calendar quarter after the current one is over. If an order is placed during the third quarter, for example, cancellation would take place at the end of the fourth quarter.
There are generally no specific dollar limits imposed by IBKR on the value of a single overnight order itself, beyond standard account and regulatory constraints. However, only Day Limit orders are allowed in the US overnight trading session. In this scenario, “DAY” implies the time during which the overnight market is open. Orders will only be active during the overnight trading hours and will expire automatically at 3:50am ET if not executed. We hope this helps answer your question!
“Importantly, GTC (Good-Til-Cancelled) orders are not supported, meaning unfilled orders will be cancelled at sessions end rather than persisting indefinitely.” Is there a plan to implement GTC+Overnight order type?
Did I read that right ,so I should feel safe in they’re not texting with picks .
TWS, Classic. I have 3 charts, same symbol, different time frames. How can the Crosshair “simultaneously show in the 3 charts, in other words, every time the Crosshair is moved in one chart it, at the same time it moves to the other two charts. Please show step by step. Thank you.
Hello armando, thank you for reaching out. This feature is not available in TWS at this time. We have passed this feedback to the appropriate team.
However, you can view the Crosshair in IBKR Desktop. After logging in, click layouts. Then you can click the square to the left of the Default dropdown. Then you can see the “Sync in Layout” options. This has a toggle for Crosshair. We hope this helps!
