Primary Features

Kill Switch functionality:

  • All Day Orders and Good ‘til orders are canceled when Kill Switch is invoked.

    Note: Kill Switch will not cancel resting orders when a market is “closed” or in the final “30 seconds” prior to an open.

  • Mass Quotes will not be canceled.

  • New order entry is prohibited.

  • Impacted customers are prevented from submitting any message other than what is required to keep alive the connection with the exchange (session management).

  • Only orders intended for CME core match engines are impacted.

  • Customers receive a reject message with entity level and administrator role information.

  • Blocking takes less than one second, though the cascading cancellations may extend beyond this time frame.
