NewOrderList (MsgType E)

applicationFIX 4.4FIX 4.2

NewOrderList is the FIX message with MsgType E, defined in FIX 4.4 and FIX 4.2. It is an application-level message: it carries a business event rather than managing the session. Its body has 21 top-level members once the standard header and trailer are counted. Earlier dialects call it OrderList; the MsgType value is unchanged.

MsgType is case-sensitive
E is NewOrderList, but e is a different message entirely — SecurityStatusRequest. Twenty-three FIX message types differ from another only by letter case.
Also known as OrderList
FIX 4.2 calls MsgType E OrderList. Same value on the wire, different name in the spec.

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.

Handle NewOrderList 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);if (message.msgType === "E") {  message.name;            // "NewOrderList"  // fields are keyed by tag; repeating groups live on message.groups}// Problems come back as data, never as exceptions:issues;                    // FixIssue[]fix.validate(message);     // dictionary-level problems

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.
