5.4 Provision for the failure of a participant's access system
1 On the (partial) failure of a participant's access system, the participant shall immediately inform Market Control of the failure or a more serious fault of its access system.
2 The participant shall simultaneously apply for permission for provisional trading. The Exchange shall grant this within a reasonable period of time and adjust individual provisions for the participant affected.
3 In such instances, the participant may also request Market Control to delete its orders. Market Control can make the following deletions:
deletion of all orders of a certain participant or trader;
deletion of all orders regarding a certain security; or
deletion of a specific order (in exceptions only).
4 The request must be made by telephone. A written confirmation of the deletion of an order and of the access system's (partial) failure must be e-mailed to Market Control as soon as possible, but no later than before the end of the current trading day.
5 Market Control may reject the deletion of orders at its own discretion.
