Can a Limit Order From Pre-Market Trading Carry Over into the Regular Session?
In most cases, limit orders from pre-market trading are only valid for that particular session and if not executed, do not carry over into the regular session. However, Interactive Brokers permits limit- or stop-limit-type orders that can be active in all trading sessions including pre-market, regular trading hours (RTH), and after-market; for such orders, the attribute "Allow Outside RTH" needs to be added.
