IT - Validity period defect in SAXESS production (61/08)


A defect in SAXESS production in handling of validity period 7 (Valid in and only in the closing call)
has been discovered. If an order is entered with validity period 7 it is expected that the order should only
be visible and tradable in the closing call. It has now been discovered that such an order is visible also in
calls triggered by a Circuit Breaker. June 2, 2008 OMX Nordic Exchange implemented circuit breakers
(volatility interrupters).
The defect will be corrected before trading July 28. A corrected version will be in SAXESS Test 3 from
tomorrow July 24.
We apologize for any inconvenience.
