SIX Swiss Exchange At Midpoint: A year of growth

SwissAtMid has offered participants improved best execution possibilities on Swiss equities with the chance of significant price improvement.



How does it work?

To access the non-displayed order book of SIX Swiss Exchange there are three options:

  • Direct order - supports limit and market orders with day, IOC or Good Till Date validity with an optional Minimum Quantity
  • Sweep order - a new order type that will check for an execution in the non-displayed order book and then the lit order book of SIX Swiss Exchange. Non-IOC Sweep orders that do not execute in full will be entered into the lit order book.
  • Plus orders - Limit Plus and Iceberg Plus orders allow for placement of resting orders into the main book that are simultaneously dual represented in SwissAtMid. They allow participants to interact with non-displayed liquidity at the mid-point whilst not missing trading opportunities in the main book.

Your advantages at a glance:

  • Open to all Swiss Blue Chips and Small/Mid-Cap Securities
  • Execution price is the mid-point of the lit order book of SIX Swiss Exchange
  • Matching carried out based on size-time priority (larger orders have priority)
  • Full support for Minimum Quantity on order entry for orders sent directly to SwissAtMid
  • All executions are done On Exchange
  • Trading in Blue Chip instruments contributes to commitment levels
  • Standard clearing and settlement with full CCP interoperability
  • Published trades are clearly flagged to identify executions via SwissAtMid
