It's early morning. Your algorithm just captured a move on ES futures while you were still asleep, but only if your Sim101 latency fix was applied correctly before the session started. Without proper tuning, simulated results often fail to match live execution because hidden system lag distorts entry prices and order fills. This gap between simulation and reality is where many high-frequency strategies lose their edge before ever risking real capital. The primary driver of latency in NinjaTrader 8 simulations is not just network speed, but how your local system processes incoming data ticks against a single-core architecture. Sim101 is a default account that represents your own simulated trades with cash balance and buying power checks identical to live accounts Source. However, the platform operates as a single-threaded application, meaning it relies entirely on high single-core CPU speed rather than distributing tasks across multiple cores. This design creates a bottleneck when processing rapid tick data or complex indicators during backtesting and real-time simulation.
