Input Arguments

collapse all

Datastream Web Services connection, specified as a datastreamws object.

Security, specified as a character vector, cell array of character vectors, string scalar, or string array. Use a character vector or string scalar to specify one security. Use a cell array of character vectors or string array to specify multiple securities. For a constituent list, specify a single security in the sec input argument, for example, "LFTSE100".

Example: "VOD"

Data Types: char | string | cell

Field list, specified as a character vector, cell array of character vectors, string scalar, or string array. Use a character vector or string scalar to specify one field. Use a cell array of character vectors or string array to specify multiple fields.

Example: ["PH","PO","P"]

Data Types: char | string | cell

Date, specified as a datetime array, numeric scalar, string scalar, or character vector. Use this date to retrieve historical data for a specific day.

Example: datetime('03-29-2018','InputFormat','MM-dd-yyyy')

Data Types: double | char | string | datetime

Start date of a date range, specified as a datetime array, numeric scalar, string scalar, or character vector. The default start date is the first date of available historical data for the specified security sec.

Example: datetime('04-01-2018','InputFormat','MM-dd-yyyy')

Data Types: double | char | string | datetime

End date of a date range, specified as a datetime array, numeric scalar, string scalar, or character vector. The default end date is the latest date of available historical data for the specified security sec.

Historical data, returned as a timetable or table. The history function returns a timetable with data for one security. For multiple securities, the history function returns a timetable for the first syntax only and a table of nested timetables for the other syntaxes. To access one of the nested timetables, use dot notation, for example, d.VOD.

Response message, returned as a matlab.net.http.ResponseMessage object. The ResponseMessage object contains an error message. To access the error message, see Access Datastream Web Services Error Messages.
