Enter and manage orders - Submit, cancel, and modify orders programmatically

Request quotes (RFQ) - Solicit competitive pricing from counterparties

Access market data - Retrieve order book depth and market snapshots

Discover instruments - Query available tradeable securities

Receive execution reports - Get real-time updates on order lifecycle events

This guide provides complete technical documentation for integrating with the 360X FIX API.
