IT – INET Production – Tick Size Changes on the Danish market (79/14)

| Source: Global Data Products

Effective September 29, 2014, tick sizes for certain equities admitted to trading on NASDAQ OMX Copenhagen as well as equities admitted to trading on OMX First North Denmark will be changed.

The change is a means to ensure better price formation for equities trading below 1 DKK.

The change requires implementation of a new tick size table and a name change for an existing one (the existing one being “XCSE Equities, DKK”).

Please note that this does not entail changes to any of the protocols.

Name change for existing tick size table

  • After the above transfer of equities to the new tick size table, table “XCSE Equities, DKK” will be empty because no order books are connected to it. We will, however, not delete the table but reserve it for future use with structured products
  • Because “XCSE Equities, DKK” will not be used with equities any more, we change the table’s name to “XCSE Warrants and Certificates”. The table’s ID does not change, it remains as is, 7.
