One platform for every
layer of FIX infrastructure

FixCore unifies the stack — from raw protocol monitoring to integration health, lifecycle reconstruction, and a Kimball warehouse you can run BI on.

OBSERVE

Real-time FIX session monitoring

Stream every message across every session. Sequence gaps, heartbeat health, and protocol drift visible the moment they occur.

  • Sub-millisecond message ingestion
  • Per-session health timelines
  • Replay and forensic mode
INTEGRATE

Integration intelligence layer

Detect counterparty quirks, message-level anomalies, and OMS divergence before they hit the trading floor.

  • Counterparty fingerprinting
  • Sequence-aware reconciliation
  • Reject pattern detection
INVESTIGATE

Trade lifecycle reconstruction

Click an order ID, get the entire flow — from new-order-single through fills, allocations, and settlement.

  • ClOrdID lifecycle stitching
  • Cross-session trace
  • Audit-grade timeline
RECONCILE

Live reconciliation engine

Match orders, fills, and allocations across counterparties in real time. Surface breaks the moment they emerge.

  • Multi-leg break detection
  • Configurable match keys
  • Auto-resolution rules
AUDIT

Lineage and audit trails

Every message, every decision, every transformation — preserved with cryptographic integrity for regulatory review.

  • Tamper-evident storage
  • MiFID II / RegNMS export
  • Immutable event log
ANALYZE

Kimball-style analytics warehouse

FIX flows roll into a dimensional model. Reporting, BI, and ML — all on top of your live trading data.

  • Conformed dimensions
  • SQL access · BI connectors
  • Custom report builder

02 / VISION

Observability today.
A Kimball warehouse tomorrow.

● PHASE 2 · ON THE ROADMAP
Every message we ingest for observability is also a candidate for analysis. FixCore is becoming a dimensional warehouse — conformed dimensions across sessions, counterparties, symbols, and time. Run BI tools, ML, or custom queries on the same data feeding your dashboards.
