Jitter Reduction

Jitter reduction is the practice of minimizing the variance in latency within a trading system to ensure consistent and predictable performance. Even if a system has a low average latency, high jitter can cause erratic execution times that disrupt high-frequency trading strategies.

Jitter is often caused by operating system background processes, network congestion, or inefficient resource allocation on the server. Optimization techniques involve pinning processes to specific CPU cores, disabling power-saving features, and isolating network traffic.

Consistent timing is vital for algorithms that rely on precise synchronization with market data feeds. Achieving low jitter is as important as achieving low latency for reliable automated trading.
