Backtesting function
The Backtesting function is used to validate the performance of an Expert Advisor (EA) trading system.
MetaTrader 4 includes sample Expert Advisors (EAs) such as MACD and Moving Average for demonstration purposes. Here, we will use a sample Moving Average as an example.
Please note the following important points:
Profitability cannot be guaranteed when using sample EAs in live trading. The information obtained from backtesting is based on historical market data.
So even if backtesting optimizes the EAs, performance is not guaranteed.
- Click ‘Strategy Tester’ in the toolbar, then choose the ‘Settings’ tab.
- Click ‘Expert Advisor’
- Select the sample Moving Average ex4.
- Choose the desired ‘Symbol’.
- Select the ‘Period’.
- Choose the appropriate ‘Model’.
- Select the desired ‘Spread’.
- Click on Use Date and then choose ‘Date and Time’.
- Set the parameters in the ‘Expert Advisor Properties’ section.
- Once all the settings are adjusted, click ‘Start’ to begin the backtesting process.
