How do I reset the Sim101 account balance?

To reset the initial cash value on your Sim101 account, open the Control Center window and select the "Accounts" tab. Click on the Sim101 account, edit the "Initial cash" property, and set it to your desired amount. This allows you to restart your simulation with a fresh balance without losing your strategy settings.

Does Sim101 include slippage and commissions?

The Sim101 account mimics live trading conditions, but you must configure slippage and commissions manually in the Trading Settings. By default, the simulator may not include these costs unless you explicitly set them in the strategy or global settings. This is critical for accurate backtesting.

Can I use Sim101 with a VPS?

Yes, you can run the Sim101 account on a Virtual Private Server. This is highly recommended for automated strategies as it ensures 24/7 uptime and lower latency to the data feed. A VPS eliminates the risk of home internet outages affecting your simulation or live trades.

Why is my Sim101 execution slow?

Slow execution in Sim101 is often caused by system resource constraints, such as high CPU usage from other applications or a bloated database. It can also be due to loading too many charts or historical data. Optimizing your system settings and cleaning the database usually resolves these issues.

Is Sim101 the same as a Demo account?

No, the Sim101 account is a local simulation engine unique to NinjaTrader 8, while a Demo account is a server-side account provided by your broker. The Sim101 account is not tied to any specific broker connection, allowing you to test strategies with any data provider.

You are running a strategy on the Sim101 account, but your execution feels sluggish. What if your Sim101 latency fix is simply a matter of optimizing your local environment rather than changing your strategy? It is a common frustration when the simulated environment does not mirror the speed of live markets. Many traders assume the delay is inherent to the simulator, but often the bottleneck lies in how NinjaTrader 8 processes data and manages system resources. The Sim101 account is a default account that represents your own simulated account through which you place simulated trades. It behaves identical to a live account in that it has a cash balance, profit and loss, and other financial parameters. Sim101 is the local simulation engine within NinjaTrader 8 that mimics live trading conditions without risking real capital. It runs entirely on your local machine, meaning its speed depends on your computer's processing power and network configuration. When traders experience delays, they often blame the simulation engine. However, the delay is frequently caused by the platform struggling to render charts, process indicators, or manage the database.
