Introduction to building trading systems for global finance

An overview of the complexity of IT systems in investment banking and the key challenges in building a global trading platform.

#2about 3 minutes

Understanding the complexity of financial assets and products

Financial products like bonds, interest rate swaps, and credit default swaps have complex parameters that IT systems must handle correctly.

#3about 3 minutes

The ecosystem of market participants and trading venues

Trading involves external clients and bank dealers interacting across numerous electronic trading venues, each with unique interfaces and protocols.

#4about 2 minutes

Core architectural components and key system challenges

The architecture uses market connectors for venue-specific logic and an order management system for common tasks like validation and routing.

#5about 1 minute

The challenge of onboarding new trading venues efficiently

Onboarding a new venue involves many steps, and a non-scalable approach leads to hundreds of tech stacks and slow time-to-market.

#6about 1 minute

Ensuring trade settlement with preventive validation controls

The settlement process, where assets are transferred, can fail if trade data is incomplete, necessitating preventive controls to validate inquiries upfront.

#7about 3 minutes

A microservices approach to separate generic and specific logic

A scalable architecture separates venue-specific logic into market connectors while centralizing generic business logic like routing in a configurable framework.

#8about 3 minutes

Safely implementing new validation rules using a soft mode

New validation rules are rolled out in a non-blocking "soft mode" with monitoring to avoid disrupting high-volume workflows, supported by business analysts.

#9about 1 minute

Summary of architecture for scalable trading platforms

A recap of the platform structure, key challenges like venue onboarding and validation, and the architectural solutions that address them.
