RTD thinkorswim supports the RealTimeData (RTD) functions in Excel in order to allow you to do your own custom bookkeeping in real time. Tab, click on the Printer icon in the top right, and choose “Export to Excel ”. Because RTD is a function in Excel, you can take full advantage of the power of Excel with functionality.
Mar 11, 2009 Ok so its specifically a problem with Excel 2013 not wanting to use the rtd plug-in. EDIT: SOLUTION. Many hours fighting RTD not working in Excel 2013 64-bit. Cells stubbornly returning #N/A. TOS support unhelpful and untinterested in pursuing. Then, success. The TOS RTD server must be manually registered with Excel using the following. Jun 13, 2015 Have you ever wondered how to include real time live data from Thinkorswim platform into a spreadsheet? Once you learn this simple technique, you will be abl.
Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
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:
- RealTimeServerProgIDA 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.
- ServerNameA 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
=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') Cylindre pocket watch serial number.
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.

You can’t beat a spreadsheet for turning big chunks of data into actionable information. Without some experience in programming, however, it isn’t always the easiest way to manipulate real-time data.
Let’s write (get it?) that wrong! It is easy to have ThinkOrSwim (TOS) stream live data into Excel but it’s not well-documented. (There’s a harder way, too, that’s not well-documented. You’ll get an overview of both, you crazy kids, but we’ll focus on the easier.) So, let’s go through a few explanations, show you how to connect the two programs and give a couple examples to get you on your way.
Why would you want to know how to do this stuff? Because you probably have a couple of ideas or questions swimming around. If you’ve got imagination and take a little time to learn, you can create a real-time model in Excel that proves (or disproves) your hypothesis or gives you answers.
And it’s fun.
On with the show!
Grab some coffee and stay awake!
Let’s slog through some technical explanations. I’ll try to make it as painless as possible BUT if you can learn to understand the difference between a Call and Put, you’re certainly able to understand the difference between DDE and RTD.
If you don’t drink coffee and couldn’t care less about technical details, jump to the next section and wait for us there.
DDE and RTD are two different mechanisms that allow Excel to talk with the outside world. Specifically, DDE (Dynamic Data Exchange) is an older technology that links Microsoft products and RTD (Real-Time Data) retrieves real-time data from a program that supports COM automation but there’s overlap for what we’re trying to do.
(I know. You’re thinking, “Where can I read more about this exciting stuff?!?!” Slow down, Turbo; you can visit https://msdn.microsoft.com/en-us/library/aa140061(office.10).aspxafter reading the rest of this article.)
Which method is better? Well, as with all things technological, the answer is “it depends.” (This iswhen most sane people throw up their arms in exasperation with most technology people. But stick with me.)
Both are kind of real-time. DDE refreshes an Excel cell when TOS updates its data; this is known as “interrupt driven.” RTD is interrupt driven, too, but Excel isn’t interrupted by TOS changing data; the interrupt comes from a clock timer, and the timer can be changed.
You can imagine that DDE may get updated faster than RTD because TOS data may change before the clock timer goes off. Is that bad? Not really if you consider we’re talking about milliseconds.
Two more items you should know:
- RTD puts less of a load on the ThinkOrSwim servers, so you can see why they want to move from DDE to RTD. (They support both mechanisms right now.)
- DDE needs “explicit data,” which means you need to give it exactly what it wants. If you want the last price of RUT in cell G2, you need to ask for the last price of RUT in cell G2. If you want the last price of SPX, you have to completely change what you ask in cell G2.RTD can use explicit data but it can also use “implicit data.” That means you can say, “Hey, G2, give me the last price for the underlying that’s in cell B2.” Better, you can change B2 from RUT to SPX anytime, without doing anything to cell G2, and G2 will return the last price of SPX.Why is that good? Because Excel can make do different things with the live data that will soon be streaming into your spreadsheet. For a non-programmer, RTD is easier to use than DDE.
What’s the conclusion? DDE may be technically faster but, for simplicity and user-level flexibility, RTD is the way to go. We’re big easy fans so let’s get moving with RTD.
In the previous section I talked about my old friends, cells B2 and G2, so we’ll use them in our example. Embrilliance essentials torrent.
Connecting Thinkorswim To Excel
Step 1: Run ThinkOrSwim. (Get itat https://mediaserver.thinkorswim.com/installer/install.html.)
Step 2: After ThinkOrSwim is running, run Excel. (We use Excel 2016 for Windows but this works in Excel 2007, too. No guarantees for any other operating system or any other spreadsheet program.)
Step 3: To keep it all straight in our head, let’s create some headers. Make cells B2 and G2 in your spreadsheet look like this:
Step 4: In cell B2 (under Symbol), type RUT.
Step 5: Ready for the magic of RTD? Paste the following into cell G2 (under LAST):
=RTD(“TOS.RTD”,”LAST”,B2)
Feel free to type it in yourself if you don’t want to copy & paste, but make sure you don’t forget the 2 commas between “TOS.RTD” and “LAST”; don’t forget the double quotes; LAST must be capitalized and remember to press the <Enter> key to accept the equation (and leave cell G2).
If you entered everything correctly, your spreadsheet should look something like this:
The number may not match because we’re looking at RUT on different days and times. Other than that – CONGRATULATIONS! What you see is TOS is giving Excel live data, the last price paid for RUT.
Now change RUT to SPX in B2 to get the last price for SPX. It worked? You’re a superstar!
Good enough for now. Experiment a little, then save this workbook as LockeRTD. Next week we’ll build on top of what you did today, make Excel do more work than you, and delve into derivatives.
