Those brokers currently have not yet resolved their technical problems. The SET discovered that the problem’s details are beyond what had been previously found out. The market therefore cannot be open at the previously estimated time and will have to again be postponed. The exact time will be announced shortly.
The SET confirms that this delay of trading was caused by the technical malfunctions of some brokers’ systems, hence blocking them from sending orders to the SET. The problem was not with the SET’s systems.
