Welcome to the OpenGamma Platform!

OpenGamma's flagship technology for financial institutions, the OpenGamma Platform, is a comprehensive solution for financial analytics capable of satisfying the full range of front-office and risk requirements. It supports pre-trade ad-hoc calculations, near-real-time streaming analytics, batch/overnight risk calculations, and complex historical scenarios and stress tests in the same system.

Built as a completely open architecture, the OpenGamma Platform is designed so that every component can be individually used, or individually replaced, based on customer requirements. We don't believe in forklift upgrades, and we built the OpenGamma Platform so that they're never necessary: individual projects can use OpenGamma components when they provide a clear advantage, and later migrate additional portions of their infrastructure if and when time and resources permit.

Visit the developer website at for more information, downloads, docs and more.


Installing and building OpenGamma

Firstly you need to make sure Apache Maven and Git are installed and working. Version 3.0.4 or later of Maven is required.

Obtaining the source code

The OpenGamma Platform is open source software using the Apache License v2. The company behind OpenGamma also offers support and some additional commercial components (The commercial components typically have dependencies with restrictive licensing incompatible with open source.) This README only refers to the open source components.

The source code can be cloned using git from GitHub:

  git clone

A source tarball can also be downloaded from


The source code must be compiled before use. This will build multiple jar files and install them into your local Maven repository. Simply run this command from the root directory of the source code:

  mvn install

The command above will run unit tests. These can be skipped to save time if desired:

  mvn install -DskipTests


For examples to introduce the system, see the sesame/sesame-examples folder.


Importing the projects into Eclipse requires following a very specific set of instructions to work properly. Full details are in the README of the eclipse subdirectory.
