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
0	Can trigger booking without reference to the order initiator ("auto")	CAN_TRIGGER_BOOKING_WITHOUT_REFERENCE_TO_THE_ORDER_INITIATOR
1	Speak with order initiator before booking ("speak first")	SPEAK_WITH_ORDER_INITIATOR_BEFORE_BOOKING
2	Accumulate	ACCUMULATE

Where tag 589 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	inside the SideCrossOrdModGrp component
ExecutionReport	8	Optional	directly on the message body
MultilegOrderCancelReplace	AC	Optional	directly on the message body
NewOrderCross	s	Optional	inside the SideCrossOrdModGrp component
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

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-fix44";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const dayBookingInst = message.fields[589]?.raw;// e.g. "0" — Can trigger booking without reference to the order initiator ("auto")// The dictionary also carries the labels:const label = fix.dictionary  .fieldByTag(589)  ?.enumValues?.find((e) => e.value === dayBookingInst)  ?.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-fix44
