Instruction cache locality is crucial in high-frequency trading engines to minimize execution latency caused by CPU cache misses. By organizing strategy execution based on instruction patterns, systems can perform a "warm-up" routine that loads necessary instruction pages efficiently before market open. This optimization ensures that strategies sharing similar logic are executed consecutively, maximizing cache hits and system stability. Task Implement a StrategyRegistry class to manage the regi
