Ahh, good grief. My bad, and completely off topic below.
I gave up on the TW API and moved on. I had high hopes... I think it was three years ago when they told me one was coming, imminent, took my info, then wouldn't respond to any queries about status or progress.
I saw in a Reddit forum (edit: sorry, I guess that was in the TDA-API Discord server) that SCHW is building out a new, improved version of the TDA API. No timelines on progress though. I'm not sure yet if I'm happy, cautious, or frightened. No matter which one, I expect that I'll have to do a lot of Python code changes....
