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.

Where tag 632 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
MassQuote	i	Optional	inside QuotSetGrp › QuotEntryGrp
MassQuoteAcknowledgement	b	Optional	inside QuotSetAckGrp › QuotEntryAckGrp
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 decimal rate where 1.0 means 100%, not 1%. @boarteam/fix parses the value as a number and reports parse/invalid-float when it does not lex as one; the raw string is kept so precision and trailing zeros are never lost.

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
