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.

Where tag 635 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
CrossOrderCancelReplaceRequest	t	Optional	inside the SideCrossOrdModGrp component
ExecutionReport	8	Optional	directly on the message body
MultilegOrderCancelReplace	AC	Optional	directly on the message body
NewOrderCross	s	Optional	inside the SideCrossOrdModGrp component
NewOrderList	E	Optional	inside the ListOrdGrp component
NewOrderMultileg	AB	Optional	directly on the message body
NewOrderSingle	D	Optional	directly on the message body
OrderCancelReplaceRequest	G	Optional	directly on the message body
TradeCaptureReportAck	AR	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.

Read tag 635 in TypeScript

decode.tsts

import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix44";const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);const clearingFeeIndicator = message.fields[635]?.raw;// e.g. "B" — CBOE Member// The dictionary also carries the labels:const label = fix.dictionary  .fieldByTag(635)  ?.enumValues?.find((e) => e.value === clearingFeeIndicator)  ?.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
