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 1222 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
DerivativeSecurityList	AA	Optional	inside DerivativeSecurityDefinition › MarketSegmentGrp › StrikeRules › MaturityRules
DerivativeSecurityListUpdateReport	BR	Optional	inside DerivativeSecurityDefinition › MarketSegmentGrp › StrikeRules › MaturityRules
SecurityDefinition	d	Optional	inside MarketSegmentGrp › StrikeRules › MaturityRules
SecurityDefinitionUpdateReport	BP	Optional	inside MarketSegmentGrp › StrikeRules › MaturityRules
SecurityList	y	Optional	inside SecListGrp › StrikeRules › MaturityRules
SecurityListUpdateReport	BK	Optional	inside SecLstUpdRelSymGrp › StrikeRules › MaturityRules

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.

import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix50sp2";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const field = message.fields[1222];field?.name;   // "MaturityRuleID"field?.raw;    // the verbatim wire stringfield?.value;  // coerced to a string

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-fix50sp2
