Alternative Streaming Quotes for US Equities

概観: 

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. Please note, this does not apply to non-IBLLC clients.

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.

All clients (IBKR Lite and Pro) have access to streaming real-time US equity quotes from Cboe One 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. Therefore and according to FINRA's enforcement of the SEC rule, IBKR provides IBLLC US clients a free default snapshot service, “US Snapshots VDR Required”. If clients do not sign up for an NBBO US equity data service and they are an IBLLC client, they will have access to free real-time snapshots when making trading decisions on US stocks. 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.
