Problem

Our portfolio analytics platform shows clients their real-time holdings value, but trade executions aren't reflected in positions until the nightly batch runs 8 hours later. The risk team also needs intraday P&L with market prices validated against multiple data vendors before they feed NAV calculations. Design a pipeline that makes positions and P&L available in near-real-time throughout the trading day.

Summary

Positions shift by the second. The math cannot lag.
