It's still being traded through brokers that people use to trade stocks. That's how it's still trading. I don't believe there's a need for a TA on a stock that's already issued anyway. The TA job is done. It's up to brokers to allow the buying, selling, covering, etc. of free trading shares.
Of course, no 15c211 means no MM's can publicly make the market by publishing the ask and bid. Still, people will try to buy low and sell high on CSHD... for whatever reason.
