"restricted "dividend" shares that I can't sell"
What is preventing you from selling those shares?
My assertion is that your broker's fee, to sell them, makes it unattractive to you.
Am I mistaken? If so, what specific additional factor, that is related to DECN, is preventing you from selling?
In my case, I happen to use Schwab as my primary broker. A sale of up to 999,999 shares costs me $8.95.
