It is early morning. Your algorithm just captured a move on ES futures while you were still asleep, or did it miss the entry because your simulation didn't account for network lag? The gap between simulated results and live performance often stems from how execution speed is modeled during testing, and Sim101 is the default account where this friction first becomes apparent. Many traders discover too late that Sim101 latency optimization is missing from their workflow until live capital starts bleeding. In practice, traders often assume that a backtest run on Sim101 mirrors live execution perfectly. This is rarely true without specific adjustments to slippage and latency parameters. The speed at which these orders fill in simulation can differ significantly from real market conditions if not configured correctly. The core issue lies in the difference between how NinjaTrader 8 processes historical data versus live simulation. Sim101 is a default account that represents your own simulated account through which you place simulated trades, behaving identically to a live account regarding cash balance and buying power checks.
