In the provided C++ microservice skeleton (synthetic feed generator, SMA-based mean-reversion strategy, and a simple order gateway), which statement best describes how the example handles order execution?
Click the option that best answers the question.
- Orders are sent to a real exchange over a production FIX/TCP connection and await actual fills.
- Orders are executed immediately by the simulated exchange in-process; position and cash are updated deterministically.
- Orders are written to an on-disk persistent order book and matched asynchronously by a background thread.
- Orders are never executed — the program only logs decisions for offline analysis and does not change position or cash.
