Are you or anyone else familiar with this market maker? I don’t believe I ever ran across it when there is chatter on who is on level 2. Showed up on TSNP today. And looking back at least 4 months on volume traded on TSNP they don’t appear.
Another stock that mentioned it recently was ENZC.
A few others - ELTP, AABB
Not sure how often that shows up since I can’t be everywhere.
