Troubleshooting Techniques
When an error occurs, the first step is to identify the source of the issue. Here are some troubleshooting techniques to help you resolve common errors:
1. Check the NinjaTrader Logs
The NinjaTrader logs provide valuable information about errors and exceptions. To access the logs:
1. Go to Tools > Options > Logging.
2. Check the Error Log and Strategy Log for error messages.
Example: An error message in the log may indicate a syntax error in the strategy code, pointing you to the exact line of code to correct.
2. Verify Strategy Inputs
Strategy inputs can impact the performance of your strategy. Ensure that all inputs are correctly configured:
1. Check that the input types match the requirements of the strategy (e.g., integers, doubles, etc.).
2. Verify that input values are within the valid ranges.
Example: An incorrect input value for a strategy parameter, such as a moving average length, can cause errors or unexpected behavior.
3. Use the NinjaTrader Debugger
The NinjaTrader Debugger allows you to step through your code line-by-line, identifying errors and exceptions:
1. Open the Strategy window.
2. Click on the Debugger button.
3. Set breakpoints to pause execution at specific points.
Example: By using the Debugger to step through your code, you can identify a runtime error caused by a division by zero operation.
4. Optimize Your Strategy
Optimizing your strategy can improve performance and reduce errors:
1. Backtest your strategy with different input values to identify optimal settings.
2. Evaluate performance metrics, such as profit/loss and Sharpe ratio.
Example: By optimizing your strategy using NinjaTrader’s Strategy Analyzer, you can improve performance and reduce drawdown.
