RTD is an Excel function that, for our purposes, opens up communications with ThinkOrSwim. RTD can act upon information sent between parenthesis in a particular order: 1. 'TOS.RTD' is sent as the 1st RTD parameter. It’s the quote-enclosed name of a ThinkOrSwim function that’s loaded into memory when you run ThinkOrSwim. The purpose of TOS. Excel / TOS RTD Support Guessing this has been asked here several times before, but I cannot seem to figure out how to get Real Time Data to stream from TOS to Excel. In Excel, I've tried going File - Options - Add-ins - COM Add-ins - GO - Add - then navigate to TOS RTDStreaming.dll file, but it tells me that it's not a valid office add-in.

Hello, recently I've tried to write calculations in Excel's VBA using the RTD from ThinkOrSwim's trading platform. I am losing sync from ThinkOrSwim after a couple of hours. My research has found that if Excel is calculating during a refresh, because of too much code, could cause it too crash. So I removed the code completely and still losing sync.

How it works

Excel acts as a middle man between ThinkOrSwim and Node JS by importing data from TOS and exporting for use with Node.

• ThinkOrSwim creates a new RTD server instance for use with RTD client applications like Microsoft Excel.
• Once the RTD connection has been established, an Excel script (VBA) runs in the background to listen for changes to the Excel document.
• If a change is detected, that row of data is exported to a file in the tos_rtd directory in a querystring format:

• The Node JS script 'listen.js' uses a built-in function to listen for changes in the 'data-stream' directory and parses the contents of the changed file.
