Staff in systems, risk management, settlement, and accounting need to know whether their firm's trading system is a packaged product, a set of separate systems for each function, or something the firm built itself. The answer affects where data flows connect and what a change touches. The thinking behind splitting or combining systems is covered in Front-to-Back System Architecture.

Three types

The ways of obtaining a trading system can be sorted into the following three.

  • A packaged integrated system is one in which the vendor describes a single product as covering several functions, such as trade capture, risk, and post-trade processing.
  • A specialist system is a product that covers a specific function, such as valuation and risk analytics, market data, or accounting and hedge accounting. It may be connected to other systems.
  • An in-house build is a system that a financial institution builds itself.

The three are not mutually exclusive. According to the US Federal Reserve's examination manual (the "manual" below), Section 2040.1 (1998), it is rare for a single automated system to handle everything from data entry through processing and control for all OTC and exchange-traded products. Systems purchased from vendors may be combined with applications developed in-house by the firm's own staff1.

The examples are limited to what each company's official materials show as of October 8, 2026.

Packaged integrated systems

Calypso, Murex, and Summit are given as examples of packaged integrated systems.

Product Operator
Nasdaq Calypso (Calypso) Nasdaq, Inc., which completed the acquisition of Adenza on November 1, 20232.
Murex's MX.3 Murex
Finastra's Summit (the current name is Summit by Teciem) Teciem, the company that took over the business from Finastra3.

The functions each company's materials list are as follows. All are the companies' own descriptions, and they do not compare whether the products cover the same functions or how deeply.

  • Calypso is described as bringing front, middle, and back office workflows together on a common platform. The areas are trading and portfolio management, risk and exposure management, collateral, funding and liquidity, clearing, and post-trade processing4. Adenza is a company combining Calypso and AxiomSL2.
  • The areas of MX.3 are sales and trading, treasury management, enterprise risk management, operations and finance, investment management, and securities finance and collateral management. It comes on premises, in the cloud, or as a SaaS offering that Murex operates5.
  • Summit is described as covering front to back for OTC derivatives and structured products. It automates the flow from real-time trade and position views through to confirmation generation, settlement messaging, payment processing, and accounting6.

Specialist systems that cover a specific function

A specialist system covers a specific function, such as market data, valuation, or hedge accounting. Some of the products in the table below list two functions.

Product Operator Function covered
ICE Data Derivatives Intercontinental Exchange (ICE) Market data, valuation
ION's Hedge Accounting ION Hedge accounting
Numerix's CrossAsset Numerix Valuation, risk analytics

The materials list the following.

  • ICE lists market data for OTC derivatives (spot, curves, volatilities, correlations) and valuation calculation services. The valuations cover interest rates, inflation, equities, FX, commodities, credit, and hybrids7.
  • ION lists templates for hedge designation and documentation and automated effectiveness testing, and says the solution supports international and US accounting standards. The material is a page for commodity trading, and it says the solution integrates with commodity trading and risk management systems8.
  • Numerix lists an analytics library for pricing and risk analytics of OTC derivatives. It can be used from Excel, Python, Java, C#, and C++, and a software development kit (SDK) lets it be embedded in the firm's own or third-party software9.

Function map

The table below lines up, for each function, what the materials list for the three integrated products and examples of specialist systems.

Function Calypso Murex Summit Specialist systems and outside services
Trade capture and positions10 Trading and portfolio management Risk-based pricing and structuring, and real-time portfolio and P&L analysis Real-time trade and position views Not covered
Valuation11 Analytics that align front office pricing and risk measures Pricing Cross-asset pricing, including standard and advanced models (a front office function) Numerix's CrossAsset (analytics library) and ICE's valuation calculation services
Risk12 VaR, expected shortfall, stress, sensitivities, and XVA Market, credit, XVA, and liquidity risk VaR, back testing, and stress tests for market risk. Credit limits, potential future exposure, CVA/DVA, and FVA for credit risk Numerix's risk scenario framework (Greeks calculation and stress testing)
Confirmation and settlement13 Confirmation, matching, and settlement processing The processing cycle for bilateral and cleared trades Confirmation generation, settlement messaging, and payment processing Not covered
Collateral14 A collateral area A collateral area Variation and initial margin, margin calls, SIMM, collateral optimization, and dispute and reconciliation Not covered
Accounting15 Not covered Investment accounting and hedge accounting in the investment management area Accounting and hedge accounting (a back office function) ION's Hedge Accounting
Market data16 Not covered Not covered Not covered ICE's market data

The level of detail in each company's self-description differs by product. Some materials name a function only by the name of an area, while others go down to indicators and items. A cell marked "Not covered" means only that the example is not listed, not that the function is absent.

Figure 1One example of how integrated systems, specialist systems, and outside services relate
Figure description

The integrated system enters the trade and holds the position. In the same step, a specialist system supplies market data. In the next step, the integrated system uses the market data to calculate valuation and risk. In the same step, an outside service confirms the trade with the counterparty, using only the trade entry and not the market data. In the step after that, the integrated system processes settlement instructions and payments. Finally, a specialist system processes hedge accounting. This figure is one example of a combination, not a standard order written in the materials. The number of systems and how responsibilities are divided differ by financial institution.

Examples of mixed setups with in-house builds

Consider a hypothetical example in which three financial institutions combine integrated systems, specialist systems, and in-house builds in different ways.

  • Company M handles everything from trade capture to accounting in one integrated product. Because it keeps customer and transaction files in one database, it may have stronger data integrity controls than with multiple data sources1.
  • Company N builds its trading and risk calculations in-house and uses commercial specialist systems for collateral management and hedge accounting. Where separate databases are used, the manual calls for reconciliation controls to be evident at each point where multiple data files are brought together1. If Company N's systems use separate databases, this applies.
  • Company P centers on an integrated system and replaces only the valuation analytics library with a specialist one, embedded through an SDK. The manual's Section 2100.1 calls for vendor models to be validated in addition to in-house models, so the models in the embedded library fall under that validation18.

Changes of operator

Operators can change through acquisitions and sales of businesses. The table below lists events whose dates are given in official materials.

Date Event Source
June 12, 2023 Nasdaq announced that it had entered into an agreement to acquire Adenza from Thoma Bravo Nasdaq announcement19
November 1, 2023 Nasdaq announced that it had completed the acquisition of Adenza Nasdaq announcement20
May 19, 2025 Finastra and funds advised by Apax announced an agreement on the sale of a business Finastra announcement21

The 2025 agreement was for Finastra to sell its Treasury and Capital Markets business to an affiliate of Apax. Completion was expected in the first half of 202621. As of October 8, 2026, Finastra's page says that the sale of this business has been completed and that Teciem has become an independent company22.
