| 10 | CheckSum | 014 |
Shown with | separators for readability. On the wire FIX uses SOH (0x01), an invisible control byte — and because BodyLength and CheckSum are computed over the actual bytes, the two forms have different checksums. Both are valid and both decode here.
Generated from the FIX 4.4 dictionary and verified at build time: it parses and validates with no issues. Open the decoder to try your own message.
Valid values
A value outside this list is not a parse error — the message still decodes — but validate() reports it as validate/value-not-in-enum.
| Value | Meaning | Symbolic name |
|---|---|---|
| 0 | Successful (Default) | SUCCESSFUL |
| 1 | Invalid party information | INVALID_PARTY_INFORMATION |
| 2 | Unknown instrument | UNKNOWN_INSTRUMENT |
| 3 | Unauthorized to report trades | UNAUTHORIZED_TO_REPORT_TRADES |
| 4 | Invalid trade type | INVALID_TRADE_TYPE |
| 99 | Other | OTHER |
Where tag 751 appears
Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.
| Message | MsgType | Requiredness | Where in the message |
|---|---|---|---|
| TradeCaptureReportAck | AR | Optional | directly on the message body |
Wire format
A whole number, optionally signed. Leading zeros are legal on the wire and are preserved in the raw value. @boarteam/fix parses the value as a number and reports parse/invalid-int when it does not lex as one; the raw string is kept either way.
