While true green-field development does exist in financial services, it's exceptionally rare. Firms already have a variety of trade processing, analytics, and risk systems in place. They may not support your current requirements, or may be lacking in capabilities/flexibility; but no firm can or should simply throw them all away and start from scratch.
We think risk technology architecture should be designed to use and complement systems already supporting traders and risk managers. Whether proprietary or vendor solutions, considerable investments have been made in terms of time and money. Discarding them and starting from scratch risks losing valuable data and insight, and adds to the cost of rebuilding.
That being said, a primary goal of any project rethinking analytics or risk computation needs to be the elimination of all the problems siloed, legacy systems have: duplication of technology, lack of transparency, reconciliation difficulties, inefficient IT resourcing, etc.
The OpenGamma Platform was built from scratch specifically to integrate with any legacy data source, analytics library, trading system, or market data feed. Once that integration is done against our rich set of APIs and network endpoints, you can make use of it across any project based on the OpenGamma Platform.
In addition, each component of the OpenGamma Platform is individually usable. This allows the incremental upgrade and migration of legacy systems, without having to move the core of the system to the OpenGamma Platform to reap the benefits. This lets you gradually migrate while continuing to deliver key functionality to the desk.
We don't believe in forklift upgrades, and neither should you. Our experience in complex integration challenges for front office and risk analytics is one of the primary reasons customers work with our implementation experts, and one of the biggest benefits commercial customers get out of their support agreements.
The OpenGamma Platform - available via an Open Source license - is a tool for developing modern, specific functionality and applications aimed at delivering more accurate, more timely data to the Front-Office. The technical team at OpenGamma is available to help integrate existing solutions and ensure the optimum benefits are achieved from its installation and future enhancements (e.g. by consolidating desks or adding other asset classes). Consider us as an extension to your IT resources, both in terms of capabilities and capacity, giving you new freedom to deliver the previously impossible.
With the OpenGamma Platform, you are not faced with the traditional build-vs-buy decision. Rather, our business model and technology stack gives you the best of both worlds: the transparency and control you get from building the whole solution in house, with a strong vendor supporting your efforts at every step along the way.
The OpenGamma Platform is designed to integrate both proprietary and third-party analytics libraries. Alternatively, it ships with the Open Source analytics library we have developed in-house. Unlike some vendors, we've invested heavily in a top-notch quantitative analysis and development team, and are producing and maintaining a modern, production quality analytics library capable of satisfying most complex trading environments. The library can be used as-is for standardized products, or as building blocks for exotic and structured pricing models. We encourage all our clients to compare this library to their own, and evaluate the merits of using an analytics library that is under continuous enhancements and provided on an Open Source basis.
