What a great option. Didn't know this existed.
WARNING
EDITING OR ALTERING ANY FILE INTHE THINK OR SWIM FOLDER OUTSIDE OF THINK OR SWIM MAY BREAK YOUR INSTALLATION
Also, if you're like me and happy working with the guts of files, there is a file in my ThinkOrSwim folder:
cache._dyqtaddn5uvmrm.tda.thinkorswim.com.xml
which contains all of the user studies in one place. Mine is a shade over 10 MB. It is an xml file, and if you open it up it looks nothing like your studies. However, if you copy the "CODE" block out of any of the xml, (if this doesn't make sense, you may not want to proceed) and paste it into someplace like this:
https://www.base64decode.org/
it will 'decode' your script. You could, of course, automate it with some python... perhaps I'll do that some day and post it here.
Just another way to get to our studies.
