Re-Setting UUID

The purpose of this test is to verify in the event of customer application failure, it may be necessary to reset the UUID intra-session on the same trading day to force synchronization of sequence numbers to and from the exchange. Re-Negotiate with a new UUID should be used only when Customer is unable to re-sync out-of-sync sequence numbers (required).
