Trading strategy optimization can be like baking a cake: you start with a basic recipe, but over time, you adjust the ingredients to enhance the flavor. Just as you might change the amount of sugar, flour, or other ingredients to achieve the perfect balance, optimizing a trading strategy involves fine-tuning it to find the right values for the input parameters that improve historical performance and have the best potential in real market conditions.
In part three of our Foundational Strategy Trading and Development series, we discuss the basic concepts and features of the Strategy Analyzer within the NinjaTrader Desktop platform. Learn about the process and theory behind trading strategy optimization, how to test and refine your strategy input parameters to help improve overall performance, and why strategy trading can be an important step on your futures trading journey.

What is the Strategy Analyzer?
Strategy optimization is performed within the NinjaTrader Desktop platform using the Strategy Analyzer. The Strategy Analyzer tool is a powerful feature that allows traders to backtest, optimize, and analyze their trading strategies using historical data.
The Strategy Analyzer window allows traders to adjust strategy parameters by automatically iterating through a range of input values—such as moving average lengths, stop loss and profit targets levels, and other variables—to find the best performing combination of parameter values over the historical backtesting period.
How to Access the NinjaTrader Strategy Analyzer for Trading Strategy Optimization
From the Control Center inside the NinjaTrader Desktop platform, go to New and select Strategy Analyzer. (Figure-1) The settings panel on the righthand side allow you to select the range of inputs to optimize, along with the symbol, bar interval, and historical timeframe. Once you run an optimization, the performance of the best results will populate in the upper and lower panels on the left.

Best Practices for Strategy Optimization
- Incremental testing: Test parameters in small, related groups with small ranges of values. This is also a good technique to help avoid overfitting the optimization results. Don't try to optimize everything at once.
- Key inputs: Try to identify those input parameters that have the greatest effect on the performance results. This will help give you a better understanding of your strategy rules and the areas you need to focus on most.
- Relevant data: Markets change over time, and input values that work historically may not work in current market conditions. It’s always good practice to optimize the most relevant recent data so the performance has the best chance of matching as you trade the strategy forward.
- Test forward: Once you have a set of parameters that you think will perform well moving forward, you can allow this strategy to run in the chart with real-time data. If the performance trading forward closely matches the historical optimized values, it may indicate that you have a solid, robust strategy.

Remember, while optimizing can enhance and improve a strategy, no amount of optimization can guarantee future success. Market conditions will change, and you will need to continuously monitor and adjust your strategy to ensure its ongoing viability.
Trading in the futures markets involves significant risk of loss and is not suitable for every investor. Past performance is not indicative of future results, and no trading strategy can guarantee profit or prevent losses.
