Logon and Carried Order Restatement

If the Carried Order Restatements port attribute is set, unsolicited Execution Report messages representing carried orders loaded by the system at startup will be sent after the Logon response. Carried orders are orders that persist across trading days. Good ‘Til Cancel (GTC) and Good ‘Til Day (GTD) orders and Day orders persisting across holiday trading segments comprising a single business date are the only order types that will appear in Carried Order Restatements (see Carried Order Restatements).
