Hi, I logged onto Refinitiv Eikon - Microsoft Excel for the first time and tried the following code on A1 cell. "=@TR("IBM","CF_CLOSE","RH=IN")" The Refinitiv Eikon is online, as does the Datastream, and I tried several variations of the code from the user guide and I still have a difficulty debugging the error "Real-Time Engine Initialization Error". Perhaps it might be because of some setting I need etc. if you could please get a help on this that would be greatly appreciated. Thanks.
