Edit and decode it yourself

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.

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
B	BIC (Bank Identification Code) (ISO 9362)	BIC
C	Generally accepted market participant identifier (e.g. NASD mnemonic)	GENERALLY_ACCEPTED_MARKET_PARTICIPANT_IDENTIFIER
D	Proprietary / Custom code	PROPRIETARY_CUSTOM_CODE
E	ISO Country Code	ISO_COUNTRY_CODE
G	MIC (ISO 10383 - Market Identifier Code)	MIC

Where tag 1133 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
CrossOrderCancelReplaceRequest	t	Optional	directly on the message body
MultilegOrderCancelReplace	AC	Optional	directly on the message body
NewOrderCross	s	Optional	directly on the message body
NewOrderList	E	Optional	inside the ListOrdGrp component
NewOrderMultileg	AB	Optional	directly on the message body
NewOrderSingle	D	Optional	directly on the message body
OrderCancelReplaceRequest	G	Optional	directly on the message body
Quote	S	Optional	directly on the message body
QuoteResponse	AJ	Optional	directly on the message body
QuoteStatusReport	AI	Optional	directly on the message body

Wire format

A single character. Most char fields are enumerated, so the value is one of a fixed set rather than arbitrary text. @boarteam/fix keeps the value as a string and, for enumerated fields, reports validate/value-not-in-enum when it is not a defined value.

import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix50sp2";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const exDestinationIDSource = message.fields[1133]?.raw;// e.g. "B" — BIC (Bank Identification Code) (ISO 9362)// The dictionary also carries the labels:const label = fix.dictionary  .fieldByTag(1133)  ?.enumValues?.find((e) => e.value === exDestinationIDSource)  ?.description;

Decode this in your own code

The same engine that produced the decoded example above is an Apache-2.0 npm package with zero runtime dependencies. It runs in Node and in the browser, and parse() returns problems as data instead of throwing.

npm i @boarteam/fix @boarteam/fix-dict-fix50sp2
