Trading Interface for Banks & Asset Managers

Trading processes depend on stable interfaces—from FIX sessions and REST APIs to proprietary market-data feeds. Order routing, pre-trade checks, and back-office posting must stay in sync within milliseconds or seconds, and every decision must remain traceable later.

Typical bottlenecks appear not at first go-live but during growth: new brokers, additional asset classes, higher message rates, or tighter reporting duties. That is when you learn whether the integration layer is truly decoupled or whether every core change becomes a release risk.

In practice we often see point-to-point connections that grew over time: one feed lands directly in order management, a second broker uses another FIX version, and test data mixes with production logs. Custom trading interfaces consolidate these paths in a monitored layer—with clear contracts, replayable logs, and separated environments.

Capital markets and asset management digitise order routing, market data, and reporting at pace. FIX remains relevant while REST and cloud-native feeds gain ground. Regulation demands complete evidence—from best execution to transaction reporting.

Institutions with clear integration architecture onboard brokers and data providers faster and cut downtime. Latency, timestamps, and session stability are operational KPIs—not IT-only topics. Versioned, tested interfaces make releases predictable rather than risky.

We implement a dedicated integration and normalisation layer between counterparties and core systems. FIX adapters, REST gateways, and feed handlers write to a unified event model; order management consumes only validated, idempotent events.

Message formats are documented with versions (FIX dictionaries, OpenAPI, Avro/Protobuf where useful). Contract tests run automatically against sandbox endpoints and simulated session resets before production releases. Circuit breakers and backpressure stop one slow broker from blocking the entire routing path.

Monitoring captures latency, session status, message gaps, and heartbeat failures in real time. Replayable logs support post-mortems and auditor exports: which order was routed when, which price was used for pre-trade checks, which reject came back.

Typical scenario: an asset manager connects three brokers via FIX and adds a REST market-data provider. All flows run in shadow mode alongside legacy routing first; after two weeks without deviation, brokers are switched one by one—with rollback plans and 24/7 alerts on session drops.

Financial regulation requires more than encryption: MiFID II demands precise timestamps, best-execution documentation, and transaction reporting; GDPR applies to personal data in order and client master data. Technically we use TLS in transit, role-based log access, and retention aligned with BaFin and internal compliance policies.

Segregation of duties and four-eyes approvals can be modelled in release workflows before routing. Audit trails are tamper-evident and exportable—for internal audit, securities-law reviews, or external auditors. Test and production data stay physically separated; no production order may originate from a sandbox session.

Penetration tests and vulnerability management for the integration zone are planned with your IT security—without unnecessarily exposing production FIX sessions to the internet.
