Trade Forensic Monitor

Trade Forensic Monitor collects all the business activities of a trade in real-time, and dynamically renders all the events that happen throughout the life cycle of a trade in a sequence diagram. This is done so that the user can easily and efficiently see what the current status of a trade order, and what is going on and what is missing. This helps and reduces the production troubleshooting time from days to seconds.
