A5X Technical Interfaces

The trading, market data and post-trade interfaces A5X exposes to exchange participants — order entry and drop copy over FIX, a binary market data feed, and post-trade capture, allocation, positioning and risk messaging. Message catalogs, session recovery rules, order identifier formats and field limits are documented in the A5X Dev Portal (Portal Tecnico), which requires credentials; no public machine-readable contract (OpenAPI, AsyncAPI, GraphQL SDL or downloadable FIX dictionary) is published at an anonymous URL, and the exchange had not begun production operations as of this profile.
