Read this bill, Brokers are not allowed to trade while globally locked!
"If counterparties nevertheless continue to trade in a security which is globally locked and those trades are submitted to DTC for settlement, those trades will also fail and be rejected in DTC’s system."
" A global lock on a security prevents the security from being transferred on the books of DTC and otherwise restricts any DTC activity with respect to the security. For so long as the global lock is in effect, Participants are unable to settle any further trades in that security, as their inventory is frozen and settlement of pending trades will fail."
If it's locked no one should be able to trade. Else what's the point of it? Something is clearly sketchy here and clearly created and unfair advantage in the market. IMO
