Standard Headers for FIX on the Zero Hash CLOB.
The FIX standard header comprises essential fields that are present at the beginning of every message in the FIX protocol. These fields are crucial for identifying and routing messages correctly within the FIX ecosystem.
| Tag | Field Name | Required | Note |
|---|---|---|---|
| 8 | BeginString | Yes | Must be set to FIXT.1.1 as this field represents the session version in FIX version 5.0. |
| 9 | BodyLength | Yes | Message length in bytes up to the checksum field, must be the second field in message |
| 35 | MsgType | Yes | The type of message proceeding the header, must be the third field in the message |
| 49 | SenderCompID | Yes | Provided by Zero Hash |
| 56 | TargetCompID | Yes | Static value for all sessions. ZERO |
| 34 | MsgSeqNum | Yes | Monotonically increasing sequence number |
| 52 | SendingTime | Yes | UTC time that the order was sent down to nanosecond resolution in the format e.g. 20230528-07:49:11.843265786. Zero Hash supports receiving in both millisecond and nanosecond. |
These fields, collectively forming the standard header, facilitate proper identification, routing, and sequencing of messages within the FIX protocol.
