How to export trade alerts from Thinkorswim

There is only one way to do this using standard functionality within Thinkorswim. The screenshot below shows how to adjust the "Notifications" settings for the platform. You can receive email/sms/push notifications using these settings. Then you can use various forms of automation on the receiving end. (that part is well beyond the scope of this forum).

Another way you might consider would be to construct a custom script to display specific values on a custom watchlist column. Then you can use the RTD() function in Excel to export the live data from that watchlist to an Excel spreadsheet. (Requires a Windows OS computer). Details for how to use the RTD() function are demonstrated in the following video:

* RTD stands for "Real Time Data" and is an Excel spreadsheet function that creates a dynamic link to data to programs which support this. The Windows OS version of Thinkorswim supports this.
