11.3 Data: Response Message Payload
A consumer requesting a Symbol List stream may also request additional behaviors from a supporting provider. To do so, the payload of its ReqMsg must contain an ElementList list that includes an ElementEntry.
The entry contains an ElementList, in which the consumer encodes entries to request the desired behaviors. The consumer should ensure that the provider supports the requested behavior by checking the Login Refresh sent by the provider. For more information, refer to .
 
 
DomainTypeThe Symbol List payload is a Map. Each MapEntry key is an AsciiString symbol. The entry’s payload can be empty or contain a FieldList which can contain additional information (i.e., permission data and cross-reference information). This information should not update frequently.
A FieldList typically includes the fields:
PROV_SYMB (3422): Contains the original symbol as provided by the exchange
PROD_PERM (1): Stores permission information
