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 571 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 5.0 SP2	Where in the message
CollateralAssignment	AY	Conditional	Optional	inside the TrdCollGrp component
CollateralInquiry	BB	Conditional	Optional	inside the TrdCollGrp component
CollateralInquiryAck	BG	Conditional	Optional	inside the TrdCollGrp component
CollateralReport	BA	Conditional	Optional	inside the TrdCollGrp component
CollateralRequest	AX	Conditional	Optional	inside the TrdCollGrp component
CollateralResponse	AZ	Conditional	Optional	inside the TrdCollGrp component
TradeCaptureReport	AE	Required	Optional	directly on the message body
TradeCaptureReportAck	AR	Required	Optional	directly on the message body
TradeCaptureReportRequest	AD	Optional	Optional	directly on the message body

Wire format

Free-form text. Any byte except the SOH separator is legal, so values are not trimmed or case-folded on the wire. @boarteam/fix keeps the value as a string; format rules are checked by validate(), which reports validate/invalid-value rather than throwing.

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
