What is a reporting code?

For each reporting requirement Distributors and Access Firms are required to register a reporting code. A reporting code is a short name or abbreviation for the vendor's service. The code is then mapped to a fee schedule on the exchange side. Reporting codes are also used when licensing and Access Firm that receives data from a Distributor. When an Access Firm identifies their vendor, they must indicate the service they receive from the vendor. This is done by selecting the Distributor registered reporting codes. 

What reporting codes do I need to register?

Below are the minimum requirements for reporting code registration. A firm may choose to register multiple codes for the same service type (simply to distinguish between services) however it is only required that single code is registered for the service type requirement.

What is prior approval?

When a Distributor or ISV Distributor registers a reporting code with the exchange, we will indicate if the service type for which the Distributor is registering requires prior approval. This means that the Distributor may not on-board a new customer for the specified service without first receiving written approval from the exchange. Typically all data feed or API services require prior approval. Any entity that receives Market Data through a data feed or API is required to be separately licensed with the exchange. Prior approval ensures the entity requesting access to a Distributor's service is adequately licensed with the exchange to receive Market Data. Note that the exchange might also contact the Distributor with instructions to immediately discontinue providing the service to any entity. A distributor is required, per the Market Data License Agreement, to comply with disconnect requests. 

How to report when distributing market data to a redistributor?

All Distributors are subject to the same reporting requirements. The Distributor is only obligated to report the redistributor under the External Real-time Data Feed/API Access Point service type requirement. The redistributor is responsible for their own reporting and is subject to the registration code service type requirements just as any other Distributor.
