bloombergEMSX

Create Bloomberg EMSX connection

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.

Creation

Description

Local Connection

example

c = bloombergEMSX(servicename) creates a connection to the local Bloomberg EMSX communications server using the service servicename with the Bloomberg EMSX C++ interface.

Remote Connection

example

c = bloombergEMSX(servicename,authid,serverip) creates a connection to a remote EMSX server using the specified service name, authentication identifier, and server IP address.

example

c = bloombergEMSX(servicename,authid,serverip,portnumber) also specifies the port number of the machine running the EMSX Server process.

example

c = bloombergEMSX(servicename,authid,serverip,portnumber,terminalip) also specifies the IP address of the machine you use to access the Bloomberg Terminal for the remote connection.

Input Arguments

expand all

Bloomberg EMSX service name, specified as one of these connection types.

Connection TypeBloomberg EMSX Service Name

Test

'//blp/emapisvc_beta'

Production

'//blp/emapisvc'

Bloomberg EMSX authentication identifier, specified as a character vector or string scalar.

This input argument is required for Bloomberg EMSX Server. If you are using Bloomberg EMSX Desktop, specify an empty character vector or string scalar because this input argument is not required.

Bloomberg EMSX Server IP address, specified as a character vector or string scalar. This address is the IP address of the machine running the Bloomberg EMSX Server process.

This input argument is required for Bloomberg EMSX Server. If you are using Bloomberg EMSX Desktop, specify an empty character vector or string scalar because this input argument is not required.

Example: '111.222.333.44'

Port number of the machine running the EMSX Server process, specified as a numeric scalar.

This input argument is required for Bloomberg EMSX Server. If you are using Bloomberg EMSX Desktop, specify an empty array because this input argument is not required.

Bloomberg Terminal IP address, specified as a character vector or string scalar. This address is the IP address of the machine you use to access the Bloomberg Terminal.

Example: '111.222.333.44'

Properties
