RTD is designed to return data continuously, but for the current value, try this: Dim xlApp As New Excel.Application Sub test Range('D1') = xlApp.WorksheetFunction.RTD('tickerplantrtdserver', Null, '4#2#1#6768#FUTSTK#N1#0#XX#Bid') End Sub xlApp is slow, so you want to initialize once only.

Description
The RTD function retrieves real-time data from a program that supports COM automation.
Syntax
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| 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. | Required |
| server | Name of the server where the add-in should be run. Parallels for mac hard drive space. 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. | Required |
| Topic1, topic2, .. | Topic1 is required, subsequent topics are optional. 1 to 253 parameters that together represent a unique piece of real-time data. | Topic1 Required Other Topics Optional |
Notes
The RTD COM automation add-in must be created and registered on a local computer. If you have not installed a real-time data server, the RTD function returns the #NAME? 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.

Summary
Note
The performance of the RealTimeData (RTD) function has been greatly enhanced in Excel M365 version 2002 or later. For more information, see Excel Performance and Limits Improvements.
This article describes the functionality that the RealTimeData (RTD) function provides. Microsoft Office Excel provides a worksheet function, RealTimeData (RTD). This function enables you to call a Component Object Model (COM) Automation server to retrieve data in real time.
When you have to create a workbook that includes data that is updated in real time, for example, financial data or scientific data, you can now use the RTD worksheet function. In earlier versions of Excel, Dynamic Data Exchange (DDE) is used for that purpose. The RTD function is based on COM technology and provides advantages in robustness, reliability, and convenience. RTD depends on the availability of an RTD server to make the real-time data available to Excel. For more information about how to create an RTD server, see the 'References' section.
The RTD function retrieves data from an RTD server for use in the workbook. The function result is updated whenever new data becomes available from the server and the workbook can accept it. The server waits until Excel is idle before updating. This relieves the developer of having to determine whether Excel is available to accept updates. The RTD function differs from other functions in this regard because other functions are updated only when the worksheet is recalculated.
Although the RTD function provides a link to data on a server, it is not the same type of link as references to cells in other worksheets or workbooks. For example, if you use the RTD function in a workbook, you do not receive the Links startup message when you open the workbook, nor can you manage the status of an RTD function through the Edit Links dialog box.
Syntax
The RTD function uses the following syntax
=RTD(RealTimeServerProgID,ServerName,Topic1,[Topic2], ..)
where the function arguments are as follows:
RealTimeServerProgID
A string that represents the Program ID of the RTD server installed on the local system. This is typically a COM add-in that is registered by a setup procedure or by using RegSvr32. RealTimeServerProgID is a required argument.
ServerName
A string that represents the name of the server on which the RTD server is to be run. If the RTD server is run locally, the ServerName should be an empty string (') or omitted.
Topic1, [Topic2], ..
Strings that determine the data being retrieved. You can use from one to 28 topics, although only one topic is required.
Using RTD
As an example of the RTD function, consider retrieving information from a server that delivers continuous data for runners in several simultaneous races. Assume that the server is provided as a Dynamic Link Library (DLL) named RaceReport.dll, that it is installed on the user's computer, and that it is registered as a COM add-in by its own setup process. The general form of the RTD function as used with this server might be as follows
Excel Rtd Add In
=RTD('MyRTDServerProdID','MyServer','RaceNum','RunnerID','StatType')
where the topics RaceNum, RunnerID, and StatType determine the race of interest, the runner whose data is required, and the type of data for a particular use of the function, respectively.
Here the user might select a cell and type the following formula in it
=RTD('ExcelRTD.RaceReport',','2','16','Time')
to see the current elapsed time for runner number 16 in race number 2. The number of topics and the nature of the associated data is determined by the developer of the COM server. For example, the race-reporting server might deliver different data if you use the following RTD function:
=RTD('ExcelRTD.RaceReport',','3','25','Position')
In this case, the data returned indicates the current position of runner number 25 in race number 3.
In this manner, the same function can be used differently throughout the workbook to retrieve different data from the same server, all of which is updated automatically.
Wrappers to Simplify Use
The RTD function can be used inside user-defined functions (UDFs) in Microsoft Visual Basic for Applications. These then become wrappers for the RTD function. This approach can be useful in shielding users from the details of the RTD server name and ProgID, and in enabling them to focus only on the data that is important to them.
For example, in the previous scenario, the user might be provided with two functions: GetTime(RunnerID) and GetPosition(RunnerID). These functions assume that the user is always dealing with the same server and race number. Therefore the user only has to specify a runner's ID to receive current data on the runner's elapsed time and position, respectively.
Calculation
Because RTD updates data when Excel is idle, it continues to receive information if Excel is in manual calculation mode. In that event, the new data is cached and the current values are used when a manual calculation is performed.
Security
RTD servers should be digitally signed. If an RTD server is not digitally signed, the server may not load, and a #N/A will be displayed in the cell(s) referencing the RTD server.
For Microsoft Office Excel 2007, you can review security settings by using the Trust Center. This can be accessed by from the Trust Center tab in the Excel Options dialog box.
For Microsoft Office Excel 2003 and in Microsoft Excel 2002, the load behavior can be altered by adjusting the macro security settings in Excel.
