Retrieves real-time data from a program that supports COM automation.

Syntax

=RTD(ProgID,server,topic1,[topic2],...)

ProgID    the name of the ProgID of a registered COM automation add-in that has been installed on the local computer. Enclose the name in quotation marks.

server    name of the server where the add-in should be run. If there is no server, and the program is run locally, leave the argument blank. Otherwise, enter quotation marks ("") around the server name. When using RTD within Visual Basic for Applications (VBA), double quotation marks or the VBA NullString property are required for the server, even if the server is running locally.

topic1, topic2,...    1 to 28 parameters that together represent a unique piece of real-time data.

Remarks

  • The RTD COM automation add-in must be created and registered on a local computer. If you haven't installed a real-time data server, you will get an error message in a cell when you try to use the RTD function.
  • When the server has been programmed to continually update results, unlike other functions, RTD formulas will change when Microsoft Excel is in automatic calculation mode.
