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)
