Hi there,nice to meet you guys. Does anyone know how do the aforementioned function work in a technical domain?Do they use a RTD server for Excel?Isn't it true that RTD server can let Excel gets real time data only, how about real time contributing values to a data sources?Thanks.

They use the underlying COM APIs (I think it is the SSL COM API) to get the data, I believe...you can retrieve real-time data using RtGet() and historical time series data using DtHistory(), IIRC. So yes, I think you can contribute, subscribe to real-time data, and historical data all from an Excel worksheet.

Thanks.I know I can contribute using RTContribute, what I were asking is the technical detail in how they implement it.1. Do they use a RTD server?2. As far as I know, RTD server can push (actually a hybird of Push and Pull) data to Excel whenever Excel is available, but what about Conbribution, is there a way for Excel to upload/send data to a real time data as well? Is that possible with RTD?3. I am asking this because I wanna make such a RTD system so that Excel can retrieve and send data from/to a Real Time data source.Thanks
