Nasdaq expands trading to 23/5
Nasdaq will extend its trading hours to 23 hours per day, five days per week. The new Day Session will run 4:00 a.m. ET to 8:00 p.m. ET and the Night Session will run 9:00 p.m. ET to 4:00 a.m. ET (with a planned 8:00 p.m.–9:00 p.m. ET daily pause for maintenance).
All NMS stocks, ETPs tradable overnight
All National Market System (NMS) stocks and exchange-traded products (ETPs) will be eligible to trade in the Night Session, which runs 9:00 p.m. ET to 4:00 a.m. ET Sunday through Thursday. That means securities you hold could be bought or sold overnight on Nasdaq during those hours.
Night Session limited order functionality
During the Night Session only limit orders will be permitted; unpriced orders (like market or pegged orders) will be rejected. Many order types and attributes allowed during the Day Session (for example, Market On Open/Close, Limit On Open/Close, Midpoint Extended Life Orders, Primary/Market/Midpoint Pegging, and certain discretion or pegging attributes) will not be available overnight.
Separate Night Session connectivity required
Firms and market participants that wish to trade in the Night Session must use ports specifically designated for the Night Session; Day ports will not connect to the Night Session. Nasdaq will offer OUCH 5, Core FIX, and FIX protocols for Night Session connectivity.
Limit Order Protection applies overnight
Limit orders entered during the Night Session will be subject to Nasdaq's Limit Order Protection (LOP). The LOP limit is the greater of 10% of the LOP Reference Price or $0.50, and orders outside those thresholds will be rejected.
Night Session launch only after SIP readiness
Nasdaq will not commence the Night Session until the Equity Data Plans / Securities Information Processor (SIP) are prepared to collect, consolidate, process, and disseminate quotation and transaction information during the Night Session and have notified the Exchange. If the Night Session Proposed Rule Change is not filed within 18 months of SEC approval, Nasdaq will promptly file a change to remove Night Session rules.
Brokers must disclose extended-hours risks
Brokers and Nasdaq members must disclose that extended-hours trading (including the Night Session) involves material risks such as lower liquidity, higher volatility, wider spreads, and unlinked markets. Nasdaq will supplement existing disclosures to address additional Night Session risks.
