Latency Simulation

Latency simulation is the practice of incorporating delays into backtesting and trading simulations to reflect the time it takes for orders to reach an exchange and be processed. In high-frequency trading and derivatives, even a few milliseconds of latency can be the difference between a profitable trade and a loss.

Latency can be caused by network bottlenecks, exchange engine throughput, or blockchain confirmation times. By simulating these delays, traders can determine how their strategies will hold up under realistic conditions where information is not instantaneous.

If a strategy relies on speed to capture arbitrage opportunities, failing to account for latency in simulations will lead to overly optimistic results. Latency simulation helps identify the operational limits of a strategy and ensures that the execution logic is robust enough to handle the inevitable delays present in decentralized and centralized trading environments.
