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	No Acknowledgement (Default)	NO_ACKNOWLEDGEMENT / NoAcknowledgement
1	Acknowledge only negative or erroneous quotes	ACKNOWLEDGE_ONLY_NEGATIVE_OR_ERRONEOUS_QUOTES / AcknowledgeOnlyNegativeOrErroneousQuotes
2	Acknowledge each quote messages	ACKNOWLEDGE_EACH_QUOTE_MESSAGES / AcknowledgeEachQuoteMessage

Where tag 301 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	FIX 4.4	FIX 4.2	Where in the message
MassQuote	i	Optional	Optional	directly on the message body
MassQuoteAcknowledgement	b	Optional	Optional	directly on the message body
Quote	S	Optional	Optional	directly on the message body
QuoteCancel	Z	Optional	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.

import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix44";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const quoteResponseLevel = message.fields[301]?.raw;// e.g. "0" — No Acknowledgement (Default)// The dictionary also carries the labels:const label = fix.dictionary  .fieldByTag(301)  ?.enumValues?.find((e) => e.value === quoteResponseLevel)  ?.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
