3. 20 April 2019, Tbilisi, Georgia Software Testing of Trading Systems Trading systems have very low-latency (within hundreds of microseconds) ,... ...have significant throughput & capacity,.... …and they should be resilient, have the ability to recover from outages and have no single point of failure 3

5. 20 April 2019, Tbilisi, Georgia Key Technical Challenges in Delivering Large Post-Trade Initiatives Challenges: A typical clearing system has highly complex features requiring high degree of accuracy and skilled resources: 1. Reference data; 2. Risk management; 3. The schedule (explained further in the presentation). 5
6. 20 April 2019, Tbilisi, Georgia Key Technical Challenges in Delivering Large Post-Trade Initiatives (continued) • The number of components of complex post trade infrastructures is very high; • Upstream and downstream systems dependency; • The participant structure is very complex; • Trade/Xfer/Position/Account life cycle; • The number of Asset Classes may vary; • The complexity of the Risk calculation process; • Access via a set of API endpoints. The challenges and their parameterizations lead to a significant number of test scenarios. 6
