Due to the new regulations for operation with the COBOS systems entering into force tomorrow, between 16.10 and 17.00 h today the access of all clients to the system will be suspended, BSE announced.

From tomorrow (10 May 2007) all users with more than one active COBOS certificate won’t have access to the system, and their active bids will be erased.

COBOS administrators will be able to deactivate their clients with more than one certificate after 13.00 h today, BSE added.

Each user (a Bulgarian or a foreign natural or legal person) can be a client of only one COBOS subscriber and is respectively allowed to have only one certificate for access to the system.

In April there were 3,049 COBOS users up 113 in one month, BSE data made available to Profit.bg showed.

There are no significant changes in the top of the list. Karoll Investment Brokerage remains leader with 775 certificates, followed by Elana Trading and BenchMark Finance with 476 and 473 certificates respectively.
