A real message using tag 864

Where tag 864 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.

Wire format

The number of entries in the repeating group that follows. The next field on the wire is the group's delimiter tag. @boarteam/fix parses the value as a number and reports parse/invalid-int when it does not lex as one; the raw string is kept either way.

Read tag 864 in TypeScript

import { createFixEngine } from "@boarteam/fix";import { dictionary } from "@boarteam/fix-dict-fix44";​const fix = createFixEngine(dictionary);const { message, issues } = fix.parse(raw);​// NoEvents is a group counter, so the entries live on message.groups —// NOT on message.fields. message.fields[864] is undefined.const entries = message.groups[864] ?? [];for (const entry of entries) {  // entry.fields is keyed by tag; entry.groups holds nested groups}
