Bloomberg Server connection V3

Since R2021a

expand all in page

Description

The bloombergServer function creates a bloombergServer object. The bloombergServer object represents a Bloomberg® Server connection using the Bloomberg V3 C++ API.

Other Datafeed Toolbox™ functions connect to different Bloomberg services: Bloomberg Desktop (bloomberg) and Bloomberg B-PIPE® (bloombergBPIPE). 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 bloombergServer. For details, see Installing Bloomberg and Configuring Connections.

Creation

Syntax

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

Description

c = bloombergServer(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.

example

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

example

c = bloombergServer(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 bloombergServer function. Otherwise, using bloombergServer as an input argument opens multiple Bloomberg connections, causing unexpected behavior and exhausting memory resources.

Properties

expand all

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

This property is read-only.

Bloomberg user, specified as a Bloomberg user identity object.

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

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

This property is read-only.

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

Example: [1x1 BLPSession]

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

Example: 8194

Data Types: double

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

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

ValueDescription
'' (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 bloombergServer object, the bloombergServer 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.

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

ValueData 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 bloombergServer object, the bloombergServer 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.
