blpsrv

Bloomberg Server connection V3

Description

The blpsrv function creates a blpsrv object. The blpsrv object represents a Bloomberg^® Server connection.

Other functions connect to different Bloomberg services: Bloomberg Desktop (blp), and Bloomberg B-PIPE^® (bpipe). For details about these services, see Comparing Bloomberg Connections.

For details about Bloomberg connection requirements, see Data Server Connection Requirements. To ensure a successful Bloomberg connection, perform the required steps before executing blpsrv. For details, see Installing Bloomberg and Configuring Connections.

Creation

Syntax

c = blpsrv(uuid,ipaddress)

c = blpsrv(uuid,ipaddress,port)

c = blpsrv(uuid,ipaddress,port,timeout)

Description

c = blpsrv(uuid,ipaddress) creates a Bloomberg Server connection object c to the Bloomberg Server running on another machine, and sets the Uuid and IPAddress properties. You need a Bloomberg Server software license for the machine running the Bloomberg Server.

c = blpsrv(uuid,ipaddress,port) also sets the Port property.

c = blpsrv(uuid,ipaddress,port,timeout) also sets the TimeOut property.

Caution

To refer to a Bloomberg connection in other functions, use the connection object created by the blpsrv function. Otherwise, using blpsrv as an input argument opens multiple Bloomberg connections, causing unexpected behavior and exhausting memory resources.

Properties

Uuid — Bloomberg user identity UUID

numeric scalar

Bloomberg user identity UUID, specified as a numeric scalar. To find your UUID, enter IAM in the Bloomberg terminal and press GO.

Example: 12345678

Data Types: double

User — Bloomberg user

Bloomberg user identity object

This property is read-only.

Bloomberg user, specified as a Bloomberg user identity object.

Example: [1x1 com.bloomberglp.blpapi.impl.aT]

Userip — IP address of the machine running MATLAB^®

character vector

This property is read-only.

IP address of the machine running MATLAB, specified as a character vector.

Example: '111.11.11.111'

Data Types: char

Session — Bloomberg V3 session

Bloomberg V3 API Session object

This property is read-only.

Bloomberg V3 session, specified as a Bloomberg V3 API Session object.

Example: [1x1 com.bloomberglp.blpapi.Session]

IPAddress — Bloomberg Server IP address

character vector | string scalar

Bloomberg Server IP address, specified as a character vector or string scalar that identifies the machine running the Bloomberg Server.

Example: '111.11.11.111'

Data Types: char | string

Port — Port number

numeric scalar

Port number, specified as a numeric scalar that identifies the port number of the machine running the Bloomberg Server.

Example: 8194

Data Types: double

TimeOut — Timeout

numeric scalar

Timeout specifying the time in milliseconds that MATLAB attempts to connect to the machine running the Bloomberg Server before timing out, specified as a numeric scalar.

Example: 10

Data Types: double

DatetimeType — Date and time data type

'' (default) | 'datetime'

Date and time data type, specified as one of these values.

Value	Description
'' (default)	Return date and time values as MATLAB date numbers.
'datetime'	Return date and time values as a datetime array.

You can specify these values using a character vector or string (for example, "datetime").

When you create a blpsrv object, the blpsrv function leaves this property unset. To retrieve data, you must set this property value manually at the command line or in a script using dot notation, for example:

c.DatetimeType = 'datetime';

Then, you can use these supported functions:

• getbulkdata

• getdata

• history

• tahistory

• timeseries

  Note

  If the DataReturnFormat property value is 'table' and the DatetimeType property value is 'datetime', then the returned data is a table that contains date and time values as a datetime array. If the DataReturnFormat property value is an empty character vector, then setting the DatetimeType property to 'datetime' returns date and time values for aggregated ticks and historical requests as MATLAB date numbers.

DataReturnFormat — Data return format

'cell' | 'structure' | 'table' | 'timetable'

Data return format, specified as one of these values, which determine the data type of the returned data.

Value	Data Type of Returned Data
'cell'	cell array
'table'	table
'timetable'	timetable
'structure'	structure

Note

The default data type of the returned data depends on the executed function. To specify the default data type, set the DataReturnFormat property to ''. For default data types, see the supported function list.

You can specify these values using a character vector or string (for example, "table").

When you create a blpsrv object, the blpsrv function leaves this property unset. To retrieve data, you must set this property value manually at the command line or in a script using dot notation, for example:

c.DataReturnFormat = 'structure';

Then, you can use these supported functions.

Supported Function	Valid Data Types for Returned Data
category	cell array (default) structure table
eqs	cell array (default) structure table
fieldinfo	cell array (default) structure table
fieldsearch	cell array (default) structure table
lookup	structure (default) table
portfolio	structure (default) table
getbulkdata	structure (default) table timetable
getdata	structure (default) table timetable
history	numeric array (default) table timetable
tahistory	structure (default) table timetable
timeseries	cell array (default for raw tick data) numeric array (default for interval tick data) table timetable

Note

Regardless of the DatetimeType property value, if the DataReturnFormat property value is 'timetable', then the getdata and getbulkdata functions return a table that contains date and time values as datetime arrays.
