FIX Protocol Tag 35: MsgType

Defines the message type, such as D for New Order Single or 8 for Execution Report. It is always the third field of a message.

Tag number: 35
Data type: STRING
FIX versions: FIX 4.0 to 5.0 SP2 and FIXT 1.1
Location: Standard header

Practical notes on MsgType

MsgType says what the message is. It is always the third field, after BeginString and BodyLength.

Session messages: 0 Heartbeat, 1 TestRequest, 2 ResendRequest, 3 Reject, 4 SequenceReset, 5 Logout, A Logon.
The order flow most sessions carry: D New Order Single, F Order Cancel Request, G Order Cancel/Replace Request, 8 Execution Report, 9 Order Cancel Reject, H Order Status Request, j Business Message Reject.
Codes are case sensitive: D is New Order Single, d is Security Definition.
Codes beginning with U are reserved for user-defined messages agreed between the two parties.

Common mistakes

A type the receiver's dictionary does not define gets a Reject with SessionRejectReason 11 (Invalid MsgType).
A valid type the application does not handle should get a Business Message Reject with 380=3, not a session Reject.

Changes between FIX versions

Each FIX version adds message types. FIX 4.2 defines 46, FIX 4.4 defines 93 and FIX 5.0 SP2 defines 164 in the standard dictionaries.

Message types that use tag 35

MsgType belongs to the standard message header, which every FIX message carries, so it is not listed against individual message types.

Field and message data comes from the QuickFIX data dictionaries for FIX 4.0 to 5.0 SP2 and FIXT 1.1, used under the QuickFIX Software License. This product includes software developed by quickfixengine.org (http://www.quickfixengine.org/). Enumerated value names are converted to plain text for reading.
