3. Request all securities, independent of market segment.
Message structure 3971 distinct fields
Source order, including nested components and groups. Group counts precede the repeated entries. “Required here” is relative to the enclosing component or group, not unconditional in the message. A dash means not marked required; conditional requirements remain in the source notes. This is a reference, not a counterparty-specific validator.
Nested fields load when needed. Open the full static layout (also works without JavaScript).
