Building a Trading Engine in Java: Beyond BUY and SELL Signals

Developing a trading bot is straightforward, but building a robust trading engine like NERV Trade in Java presents complex engineering challenges. While generating BUY or SELL signals is simple, executing them reliably requires addressing critical issues. These include managing partially filled orders, handling duplicate execution reports from brokers, and ensuring data persistence during application crashes. Developers must account for scenarios where brokers fail to respond or applications restart while orders remain active to ensure system stability.
