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, Expected 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 exchange). 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.

TradeStore is one of the core applications within the IPA domain. Its strategic purpose is to provide uniform pricing of trade portfolios, independent of the data structures or complexities of upstream deal‑capture systems (e.g., Murex, Summit).

Tradestore is responsible for:

• Capturing and processing all trade feeds across the bank via multiple integration methods, and managing their full lifecycle

• Modeling trade data in a uniform format per product type using Google Protocol Buffers and compressed serialization

• Serving data through high‑throughput APIs based on gRPC and distributed in‑memory caching systems to support end‑of‑day risk calculations

• Streaming trade data for pre‑deal pricing and real‑time decisioning
