Examples
Retrieve Information for Last Price Field
Create a Bloomberg connection, and then retrieve information for the last price field.
Connect to the Bloomberg Server using the IP address of the machine running the Bloomberg Server. This example uses the Bloomberg Server C++ interface and assumes the following:
The Bloomberg UUID is
12345678
.The IP address for the machine running the Bloomberg Server is
'111.11.11.111'
.
c
is a bloombergServer
object.
uuid = 12345678;
ipaddress = '111.11.11.111';
c = bloombergServer(uuid,ipaddress);
Return data as a table by setting the DataReturnFormat
property
of the bloomberg
object. If you do not set this property, the
fieldinfo
function returns data as a cell array.
c.DataReturnFormat = 'table';
Retrieve the Bloomberg field information for the LAST_PRICE
field.
f = 'LAST_PRICE';
d = fieldinfo(c,f);
Display the last four columns in the returned Bloomberg information.
d(:,2:5)
ans = 1×4 table ID MNEMONIC DESCRIPTION DATATYPE _______ ____________ _______________________ ________ 'RQ005' 'LAST_PRICE' 'Last Trade/Last Price' 'Double'
The columns in d
are:
Field identifier
Field mnemonic
