Introduction

In the world of capital markets, milliseconds matter. Every trade, every position, and every risk calculation depends on systems that can perform with speed, reliability, and accuracy.

Among these, FIS Front Arena stands as one of the most trusted and versatile trading platforms in the industry — used by investment banks, asset managers, and financial institutions worldwide.

Front Arena isn’t just a trading tool; it’s a complete ecosystem connecting traders, risk managers, and operations teams through a single, integrated platform. From real-time pricing and analytics to risk management and post-trade processing, it enables institutions to see, act, and respond to markets faster and smarter.

What is FIS Front Arena?

FIS Front Arena, now officially called the FIS Cross-Asset Trading and Risk Platform, is a cross-asset, real-time, front-to-back solution for organizations trading in global capital markets.

The platform offers:

Order and execution management (including internalization)

Sales, trading, and market making

Pricing, position, and risk management

Operations and settlement

Online trading and connectivity across all asset classes

What makes Front Arena truly unique is its cross-asset design. Whether it’s equities, FX, fixed income, commodities, or derivatives, the platform provides a unified environment for trading and risk across products — something few systems achieve effectively.

Why Leading Institutions Use Front Arena

Financial institutions face constant challenges: fragmented systems, data silos, regulatory pressures, and high-volume trading demands.

Front Arena addresses these through:

1. One Platform for All Functions

Front Arena connects front, middle, and back office functions in a single ecosystem.

This eliminates multiple data transfers, reduces operational risk, and ensures every department works with the same information.

2. Real-Time Decision Support

Its real-time data synchronization enables instant position visibility, mark-to-market valuation, and risk monitoring  critical for volatile markets.

3. Scalable Architecture

From boutique firms to tier-1 global banks, Front Arena’s modular architecture scales easily. It can support a few desks or hundreds of traders while maintaining performance and data consistency.

The Architecture Behind the Power

Front Arena’s strength lies in its client/server architecture and data-driven design.

Let’s break down the key layers that make it work:

PRIME - The User Interface

PRIME is the graphical interface traders and analysts use every day. It provides:

• Real-time positions and risk
• Deal entry and pricing tools
• Market data visualization
• Customizable dashboards
• 
  

PRIME is a desktop application, purpose-built for trading desks where complex financial models and real-time analytics are required. Its responsive design and customization flexibility make it the preferred interface for global trading teams.

ADS - The Arena Data Server

The Arena Data Server (ADS) is the core data engine of Front Arena.

It caches, stores, and manages all trading, pricing, and market data using a Microsoft SQL Server backend.

Key responsibilities:

• Real-time data subscriptions
• Audit logging of every change (before/after values)
• Intelligent caching for performance

When a client retrieves data from ADS, it establishes a subscription. If that data changes — say a trade is updated or a price moves ADS automatically pushes the new data to the client.

This ensures every user across the organization always works with the latest, synchronized data.

AMB and AMBA - The Messaging Backbone

AMB (Arena Message Broker) and AMBA (Arena Message Broker Adapter) manage communication between Front Arena components and external systems.

Together, they handle:

• Data publishing: Exporting trade and market data to downstream systems
• Data importing: Receiving updates from exchanges, data providers, or other internal systems
• Message recovery: Ensuring no data is lost even if a connection temporarily fails

This publish/subscribe messaging model makes Front Arena highly resilient and suitable for complex integration landscapes.

ATS - The Arena Task Server

The Arena Task Server (ATS) automates workflows, report generation, and batch jobs.

It combines scripting capabilities (AELSS) with the Arena Class Model (ACM) and Arena Data Flow Language (ADFL) to execute logic outside of the GUI.

This separation of user interface and server-side logic allows for high performance, automation, and 24/5 operational reliability essential in trading operations.

PACE (APS, and APSE) - The Performance Layer

Front Arena’s PRIME UI is a thick client that runs on the desktop, designed for traders and risk managers to handle rich data and complex financial calculations.

However, performing all calculations locally can make the desktop resource-intensive, especially during peak trading hours when portfolios, sheets, or risk scenarios become very large.

That’s where PACE (Parallel Asynchronous Capacity Engine) comes in.

PACE introduces distributed processing, allowing heavy computations to be offloaded from the user’s desktop to powerful backend servers.

Here’s how the flow works:

APSE (ATS Workers and Subworkers) → ADS (Arena Data Server) → PRIME User Session (Trading Manager)

When a trader performs an action in PRIME - for example, recalculating a large portfolio, the workload is distributed to ATS workers and subworkers managed by the Arena PACE Server (APS).

These workers, running on Linux or Windows servers, perform the heavy mathematical and risk calculations. Once complete, the computed results are sent back through the ADS and displayed instantly in the user’s PRIME session.

This architecture ensures that the trader’s desktop remains lightweight, with minimal CPU and memory requirements, while still delivering real-time results and high responsiveness even under extreme workloads.

In essence, PACE transforms Front Arena into a scalable distributed computing environment, combining power, precision, and performance across client and server layers.

How It All Connects

Front Arena’s architecture is elegantly modular:

• ADS is the data brain.
• PRIME is the face traders interact with.
• AMB/AMBA are the communication channels.
• ATS drives automation.
• PACE/APS/ APSE ensure scalability and responsiveness.

Together, they create a real-time ecosystem where data flows seamlessly, decisions happen instantly, and performance scales with market demand.
