If you’ve already tested a backtest in MetaTrader 5, it’s time to take the next step: optimizing your Expert Advisor (EA) to find the best possible parameters. This process, known as optimization, allows you to adjust hundreds of settings and detect the combinations that offer the highest return and the least risk.
Improve your expert advisor’s performance and take your strategy to the next level
In this practical guide we teach you how to perform an optimization in MetaTrader 5 (MT5), what kind of algorithms you can use, how to interpret the results and, most importantly, how to apply it to a real system like Smart Metrics EA, an advanced trading bot for trading on M15.
⚙️ What is an optimization in auto trading?
Optimization is a process by which MetaTrader 5 executes multiple backtests of an expert advisor by automatically varying its parameters, with the aim of identifying the most effective combinations.
The goal is to find the best set of possible configurations based on:
- Total return
- Minimum drawdown
- Profit ratio
- Robustness in the face of variable conditions

🚀 Advantages of Optimizing in MetaTrader 5 vs. MT4
MetaTrader 5 incorporates a much more powerful optimization engine than its predecessor. Here are its key benefits:
| Function | MT4 | MT5 |
| Multicore optimization | ❌ No | ✅ Yes |
| Genetic algorithm available | ❌ No | ✅ Yes |
| Optimization with remote agents | ❌ No | ✅ Yes (ideal with VPS) |
| Backtest multimoneda | ❌ No | ✅ Yes |
| Simulation speed | 🟡 Stocking | ✅ Registration with results cache |
With Smart Metrics EA, you can take advantage of all these advantages to find the ideal preset for pair and seasonality. You have already optimized sets here.
🛠 How to optimize in MetaTrader 5 (step by step)
1. Open the Strategy Tester (Ctrl+R)
Select the expert advisor to optimize (e.g., Smart Metrics EA).
2. Choose symbol and period
Example:
- Symbol: GBPUSD
- Temporality: M15
- Model: “Every tick based on real data”
3. Activate the “Optimization” option
Check the “Optimization” box and select the type (I’ll explain the differences later).
4. Set the date range
The longer the data period, the more robust the results. At least 1–2 years is recommended.
5. Set the parameters to optimize
Click on “EA Properties” → “Tickets” tab. Defines the minimum, maximum, and step values for each parameter.
🎯 In Smart Metrics, you can optimize parameters such as:
- Distance of deviation from the mean
- Fractal activation
- Schedule filters
- Partial Shutdown Logic
6. Select the optimization algorithm
- Full algorithm: test all possible combinations
- Genetic algorithm: faster, tests only the best variants
7. Start the optimization
Click “Start.” You can see the progress in the “Optimization results” tab.
📊 How to interpret optimization results
When finished, MT5 will display a table with:
- Net Profit
- Drawdown máximo
- Total Operations
- Average daily/monthly return
- Sharpe Index or Profit Factor
Double-click on the best line to launch a visual backtest with those parameters.

✅ Tips for effective optimization
| Advice | Why it matters |
| Avoid over-optimizing | Don’t look for the “perfect setup”, look for robustness |
| Use long periods | Minimum 1 year for statistically useful results |
| Validates with out-of-sample data | Test the result in a period that wasn’t used to optimize |
| Combina con forward testing | Validate the preset in real demo |
| Use VPS | To run tests without interruption (see our technical services) |
