Definitions

In plain terms

Feeds can deliver trades, quotes, order-book changes, status messages, and reference fields in real time or as historical files.

Technical

A feed contract specifies product and venue scope, schemas and versions, message ordering, timestamps, identifiers, corrections, entitlements, delivery guarantees, and operational notices.

Scope

A feed is not a neutral view of the whole market; coverage and licensing are part of its meaning.

Examples

  • A governed dataset records market data feed explicitly and preserves the source context needed to interpret it.

Common misconceptions

  • Market Data Feed does not have one universal meaning or policy without its declared source, scope, and data contract.
