How would you design a low-latency trading system in Julia?

A low-latency system in Julia requires allocation-free hot paths, precompiled functions, and strict control over GC.

Low-latency trading systems in Julia must eliminate runtime allocations, avoid dynamic dispatch, and precompile all critical functions. Buffers are preallocated, GC is minimized, and threads are pinned to CPU cores. Julia can be used for strategy computation while order execution may rely on C-level interfaces.
