IB maintains a trade order desk within each of its US, European and Asian Customer Service Centers, effectively providing 24 hour support for phone orders.  Traders should note that the order desk facilitates closing market orders only and such orders are assessed a Telephone Order fee of USD 30, or equivalent, in addition to all regular commissions.  A listing of phone numbers for each of the Service Centers which we recommend you print and maintain in the event you experience an Internet outage may be found here.
