Purpose-built stacks for prop desks and brokers: Scalable, reliable and Cutting-Edge.

  • Low-latency Golang/C++ gateways; SOR; co-location & direct market access.
  • Market-data normalization & tick stores; real-time analytics (VWAP, imbalance, auctions).
  • OEMS with pre-/post-trade risk; advanced order types; throttling/kill-switches.
  • Multi-asset: equities, futures, options, FX, crypto; FIX & proprietary protocols.
  • Observability: ELK/Prometheus/Grafana; synthetic monitoring; alerting & runbooks.
  • HA/DR: active-active clusters, replication, RTO/RPO design and testing.

What we deliver

Heavy Systems are individually engineered trading stacks that combine ultra-fast connectivity, robust market-data infrastructure, institutional-grade OEMS, and end-to-end operations tooling. We tailor architecture and latency budgets to your venue mix, brokerage stack, and regulatory footprint—reusing our proven modules to compress delivery time and risk.

Performance, Data, and Reliability at a Glance

Latency Budget
(p50 / p99)

We track and shrink the latency budget across the whole path (wire → gateway → SOR → venue).

Market-Data Footprint

The mix shows capacity dedicated to real-time feeds vs. historical storage/replay—tuned to your symbols, depth, and analytics (VWAP, imbalance, auctions).

Observability & Reliability Coverage

Coverage targets align with venue SLAs: alerting, runbooks, and DR drills keep the stack audit-ready and predictable in production.

Core capabilities

Low‑latency connectivity & routing

FIX/proprietary protocols, optional co‑location/DMA, SOR with throttling, kill‑switches, and venue fallbacks.

Market‑data platform

Multi‑source ingestion, normalization, distribution; tick stores and historical TSDB; real‑time analytics (VWAP, imbalance, auctions).

OEMS for professionals

Advanced order types, bulk ops; pre‑/post‑trade risk; account hierarchies and allocations across assets.

Observability & SRE

ELK, Prometheus, Grafana; synthetic monitoring, alerting, and on‑call runbooks.

HA/DR by design

Active‑active clusters, replication, failover drills; RTO/RPO planning and validation.

Why FIVEFINS:

For Prop Desks

  • Latency first, by design. Native/FIX gateways in C++/Rust, co‑location/DMA, wire‑to‑wire optimization.
  • Execution edge. Venue‑aware SOR, throttling/kill‑switches, drop‑copy ingestion, fast cancel/replace.
  • Market‑data muscle. Multi‑feed handlers, normalization, tick store & replay; real‑time analytics.
  • Trader workflow APIs. Strategy/automation hooks (Python/C++), plug‑in adapters.
  • Operational clarity. End‑to‑end observability, latency histograms, synthetic probes, DR drills.
  • Proven delivery. Production systems under tight SLAs and external audits.

For Brokers

  • Multi‑prime connectivity. Route across prime brokers; client FIX/REST APIs; best‑execution policy enforcement.
  • Business controls that scale. Account hierarchies, pre‑/post‑trade risk, maker‑checker, flexible fees/commissions.
  • STP across FO/MO/BO. Allocations & confirmations, pre‑settlement controls, reconciliations, settlement & treasury flows.
  • Client experience. OEMS + Client Portal, statements and self‑service reporting, role‑based access (SSO/SAML/OIDC).
  • Operate under scrutiny. Audit‑grade logging, evidence packs, change control and runbooks.
  • Scale & resilience. HA with seamless failover and reference capacity tiers.
