i don't know of a link to track watchers on Stock Twits, I just note it myself every so often. For the August 2018 number I mentioned, I had posted it here back then, I searched my posting history for it.
I have been making notes for all of my stock moves, what I was thinking and so on at the time, I don't track watchers daily but am aware. The note taking process has helped me alot over the past 2 years.
