The Mission

In the Financial Market environment, building a platform integrating your own pricing and risk models is crucial to stay in control of your risk while keeping a competitive edge. ING Financial Markets has taken up the challenge by initiating the building of the ING Pricing Architecture (IPA) platform.

The IPA project landscape consists of service-oriented components that will enable the real-time and portfolio calculations of financial risk metrics and simulations (e.g. VaR, Epected Shortfall, Bilateral Margining) which are driven by new ECB regulation as well as advanced Risk analysis on the derivative product portfolio of Financial Markets (interest rates, credits, foreign echange). This will be a key platform in the IT landscape for our global dealing rooms, with 10 scrum teams cooperating towards one Financial Markets IT landscape.

The Trade Store project is one of the essential applications within the IPA domain. It serves the strategic Area purpose of pricing trade portfolios in a uniform way, regardless of data formats or additional compleities of various deal capture systems within the bank (e.g. Mure, Summit). Aside from secondary purposes, the Trade Store application is responsible of:

Capturing all trade feeds within the bank via various integration methods, and handling their lifecycle;

Modeling the data in a uniform format based on each specific product using Google protocol buffers and compressed serialization;

• Serving the data via high throughput APIs based on Google RPCs and distributed in memory caching systems for EOD risk pricing purposes;
• Streaming the data for pre-deal pricing purposes;
