On Approval of Amendments to the Requirements for Synchronization of Date and Time Recording Systems

The National Commission for Securities and Stock Market approves amendments to the Requirements for Synchronization of Date and Time Recording Systems, requiring market operators, trading participants, and clearing entities to align their activities with the updated standards within twelve months of the decision's entry into force. The amendments redefine key terms, mandate specific accuracy levels and timestamp granularities for different trading activities as detailed in the attached tables, and establish synchronization protocols between electronic trading systems and reference time sources. Compliance is mandatory for all entities conducting professional activities on organized markets, with specific tolerances ranging from 100 microseconds for high-frequency algorithmic trading to one second for other activities.
