Sustainable Green Team Ltd. (SGTM)

[$UPERMAN]

If a broker has a buyer and seller themselves can they trade the stock even with a DTCC chill?

NO. DTC is the Clearing House of the Shares.
All shares must be cleared by TDC Services
or they are Unregistered Shares Transactions
and can cause further delays of clearing DTCC.

Nope, bad situation until DTC clears SGCP and
prolly wont until Fairhills situation gets resolved,
if ever at all again.
