Interactive Brokers Updates Platforms for Odd Lot NBBO Display
Electronic trading major Interactive Brokers has updated its platforms to align with new SEC requirements on Odd Lot information. These changes took effect after April 27, 2026, when the SEC amended rules under Regulation National Market System (Reg NMS). The updates ensure users can access this data directly in trading tools.
SEC’s New MDI Rules
The Market Data Infrastructure (MDI) Rules now require Odd Lot information in exclusive Securities Information Processor (SIP) feeds. Market participants with SIP subscriptions can view and access Odd Lot orders as a result. Now, exchanges publish odd lot National Best Bid and Offer (NBBO) alongside the existing round lot NBBO. It adds to the current data without replacing it.
Platform Enhancements at IBKR
Now, IBKR platforms receive, process, and show odd lot NBBO details right within Order Entry. The setup helps traders see the full picture of available bids and offers, including smaller lot sizes. The feature integrates efficiently into the existing interface for quicker decision-making.
How to Access Odd Lot Data
Users can view the information with simple steps in the platform. First, select Odd Lot Data in the top right corner of the quote details. The Odd Lot Data will then appear on the screen. This direct access supports compliance with the new rules while improving order entry workflows.
