Nope - But I do now - old dogs new tricks.. While I have been holding and trading certain OTC stocks for a long time, I haven't much concerned myself with who the smaller mm's are. I know who the regulars are, but when someone new comes along, I don't much care. When they are active, I generally google them. Maybe it would have been a better idea to go to otcmarkets first.
I remembered Family posting a list of mm's and how much they sold in a given month and I thought - interesting, I wondered where he found that. It listed that particular market maker - Buckman - It caught my eye because they did about 2% and I didn't even realize they were there - in December. I also found his post interesting because OTCN did about half that of Cdel. I am pretty sure that much of Citadel was on the bid tho. And GTSM was the leader - again, a ton of shares on both the ask and the bid - always. OTCN seems to be working a lot harder on the ask. he has been around here for a very long time and not in a positive way.
