FIX API for trading and market data streaming. Can be integrated with existing O/EMS systems or used for building new solutions. Suitable for all trading activities, including HFT
Axon Trade EMS offers real-time normalized L2 data and execution services via FIX 4.4. If FIX is already part of your stack, and you’re looking for a vendor to handle OKX routing, you’re in the right place.
Everything you need to trade across top crypto exchanges using a single FIX 4.4 API – fast, normalized, and battle-tested
Orders can be submitted, modified, canceled, and tracked through all status transitions via consistent ExecutionReports
Snapshot (35=W) and incremental (35=X) streams are available through FIX, aligned with exchange state
Access to balances, trades, and balances, positions, deposits and withdrawals. Account-level data is exposed via FIX
Sessions are managed automatically, with heartbeat tracking, reconnect logic, and sequence handling included
All symbols are mapped into a unified format across venues – no need to maintain custom naming logic for each exchange
End-to-end FIX processing adds under 100 microseconds; latency is measured, monitored, and stable
Standardized FIX sessions work consistently across 30+ exchanges, with routing logic unified for all venues
Production sessions can be live in two business days or less, with credentials, configuration, and support included
Integration, troubleshooting, and ongoing ops are handled by engineers with hands-on protocol experience — not support agents.
From market makers to OMS teams and platforms — these are the most common ways trading firms integrate with our FIX API for OKX

From routing and permissions to data layout and metadata — every detail is optimized to simplify integration, increase consistency, and support complex trading setups at scale
Market data and trading activity are handled through separate FIX sessions, reducing load and simplifying flow management
Fine-grained access control over which accounts can trade where — useful for platforms and broker models
Each session begins with a full book snapshot (35=W), followed by incremental updates (35=X)
Non-trading operations (e.g., creating accounts, assigning venues) are handled via REST, separate from FIX sessions
Key fields like Symbol (55) and SecurityExchange (207) are promoted outside of NoMDEntries, simplifying parsing and eliminating redundancy
Systems can subscribe to session status messages and react to changes — no need for polling or manual monitoring.
SecurityList (35=y) responses include price precision, min quantity, and lot size — enabling pre-validation and proper formatting
Unified definitions for security types, order types, time-in-force, and other enums ensure schema stability and forward compatibility
Flexible identity model allows firms to manage multiple accounts and logins under one org — ideal for segmented operations
Planned downtime windows (typically <10 minutes) are announced in advance, helping teams schedule around them with confidence
