Market Data and Connectivity


IEX Exchange offers connectivity to the exchange via physical ports as well as logical ports (also called trading sessions), which are used by broker-dealers to submit orders. IEX Exchange offers physical connectivity for free and charges $100 per month for each extra port after a user’s first five ports.
