bloombergEMSX
Description
The bloombergEMSX
function creates a
bloombergEMSX
object, which represents a Bloomberg® EMSX connection using the Bloomberg V3 C++ API. After you create an bloombergEMSX
object, you can
use the object functions to create and route orders, and then manage orders and routes. For
details about Bloomberg EMSX, see the EMSX API
Programmers Guide.
