All messages (administrative or application) are preceded by a Standard Header. In addition to providing the identification of FIX Session participants, the Standard Header identifies the Message Type (Tag 35), Message Length (Tag 9), Origination times (Tag 52 and Tag 122) and Message Sequence order (Tag 34). The Standard Header also offers additional information on FIX Session authentication, resent messages, duplicated messages and message routing and delivery.
