The iLink 2 Order Entry Business layer, also referred to as the Application layer, entails the business transaction functionality provided by CME Globex. Once the client system has established a FIX session (Session layer), the client is able to transact business through the sending and receipt of Application layer messages.
The Order Entry Application Layer consists of the following topics:
- iLink Order Management
- User Defined Spread - UDS
- User Defined Instruments - UDI
- Order Status Request - OSR
- Mass Quotes
- Mass Quote Protections
- Quote Request - RFQ
- Cross on CME Globex
- Give-Ups
- Point of Order Origination
- Trading on Behalf of a Client
- Mass Order Status
- Mass Order Cancel
- Implied Orders
To avoid client systems impacts, CME Group recommends that client systems NOT submit iLink messages containing FIX tags that are not defined in the iLink message specification.
