Alternative Streaming Quotes for US Equities

Overview: 

The SEC Vendor Display Rule requires that brokers give clients access to the NBBO at the point of order entry. In order to provide users with free live streaming market data, we cannot display this free stream when entering an order without the client subscribing to the paid NBBO.

Background: 

Under the Rule 603(c) of Regulation NMS (Vendor Display Rule), when a broker is providing quotation information to clients that can be used to assess the current market or the quality of trade execution, reliance on non-consolidated market information as the source of that quotation would not be consistent with the Vendor Display Rule.

Therefore and according to FINRA's enforcement of the SEC rule, any client of a broker that is purchasing real-time quotes must buy the NBBO real-time services when making trading decisions.

All clients have access to streaming US equity quotes from the four CBOE exchanges and IEX at no charge. Since this data does not include all markets, we cannot show this quote when entering parameters for a US stock quote. Order routing will not change based on what is shown on the screen. If one is subscribed to NBBO quotes or not, by default the trade will still take place with the assistance of the SMART order router designed to provide the best price for the order.

Please see the sample screenshots below from TWS Classic and TWS Mosaic for what occurs when placing an order without the NBBO streaming subscription for US equities.
