As a financial analyst, the RTD function is very useful, as it helps in refreshing values from real-time data servers in Excel spreadsheets. As a financial analyst, we can use cell values as formula arguments and build powerful refreshable data sheets and models in a few minutes.
Formula for Real Time Data
=RTD(ProgID, server, topic1, [topic2], …)
The RTD function uses the following arguments:
ProgID (required argument) – The name of the ProgID of a registered COM automation add-in installed on the local computer. We need to enclose the name in quotation marks.
Server (required argument) – This is the name of the server where the add-in should be run. If there is no server and the program is run locally, we leave the argument blank. Otherwise, we need to enter quotation marks (“”) around the server name. When using RTD within Visual Basic for Applications (VBA), double quotation marks or the VBA NullString property is required for the server, even if the server is running locally.
Topic1, topic2, … – Topic1 is required argument, however, the subsequent topics are optional. 1 to 253 parameters that together represent a unique piece of real time data.
