I came across a CEF called CLM. They have a DRIP so that you reinvenst the distributions at the NAV price instead of the open market price.
Fidelty & etrade are able to enroll you, but IBKR, tastytrade (and probably more) do not
Why would a broker not support this? Is this about them missing commisions?
