Search for Bloomberg Last Price Field
Create a Bloomberg connection, and then request the category description of the last price field.
Create a Bloomberg B-PIPE connection using the IP address of the machine running the Bloomberg B-PIPE process. This example uses the Bloomberg B-PIPE C++ interface and assumes the following:
The authentication is Windows® authentication when you set
authtype
to'OS_LOGON'
.The application name is blank because you are not connecting to Bloomberg B-PIPE using an application.
The IP address for the machine running the Bloomberg B-PIPE process is
'111.11.11.112'
.The port number of the machine running the Bloomberg B-PIPE process is
8194
.
c
is a bloombergBPIPE
object.
authtype = 'OS_LOGON'; appname = ''; ipaddress = {'111.11.11.112'}; port = 8194; c = bloombergBPIPE(authtype,appname,ipaddress,port);
Return data as a table by setting the DataReturnFormat
property of the bloomberg
object. If you do not set this
property, the category
function returns data as a cell
array.
c.DataReturnFormat = 'table';
Request the Bloomberg category description of the last price field.
f = 'LAST_PRICE';
d = category(c,f);
Display the first three rows of the Bloomberg category description data in d
.
d(1:3,:)
ans = 3×5 table CATEGORY ID MNEMONIC DESCRIPTION DATATYPE __________ _______ ________________________________ ________________________________ ________ 'Analysis' 'OP179' 'THETA_LAST' 'Theta Last Price' 'Double' 'Analysis' 'VM048' 'DDMX_PERCENT_CHANGE_LAST_PRICE' 'DDMX Percent Change Last Price' 'Double' 'Analysis' 'YL005' 'YLD_CNV_LAST' 'Last Yield To Convention' 'Double'
The columns in d
are:
Category
Field identifier
Field mnemonic
Field name
Field data type
Close the Bloomberg connection.
