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 769 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
CollateralAssignment	AY	Conditional	inside the TrdRegTimestamps component
CollateralInquiry	BB	Conditional	inside the TrdRegTimestamps component
CollateralReport	BA	Conditional	inside the TrdRegTimestamps component
CollateralRequest	AX	Conditional	inside the TrdRegTimestamps component
CollateralResponse	AZ	Conditional	inside the TrdRegTimestamps component
Confirmation	AK	Conditional	inside the TrdRegTimestamps component
TradeCaptureReport	AE	Conditional	inside the TrdRegTimestamps component
TradeCaptureReportAck	AR	Conditional	inside the TrdRegTimestamps component

Wire format

A UTC date and time. The fractional-seconds part is optional, so two timestamps can be equal but not byte-identical. @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
