Testing Strategies and Indicators on MT4®/MT5®

MetaTrader® trading platform features a Strategy Tester that you can use to test auto-trading robots (or Expert Advisors) and trading indicators in visual testing mode.

However, to test indicators or trading strategies in MetaTrader®, you need to fulfill certain conditions.

1. Enable the Strategy Tester. To do this, head to the "View" menu located at the upper-right corner of the dashboard. Click on the "Strategy Tester."

When you’ve done that, the "Strategy Tester" window will open on the lower section of the screen. This is where the entire MetaTrader® testing procedures take place.

The window contains both the Expert Advisors and indicators testing elements. You can select your preferred element and move on with the testing process.

Besides testing available indicators and expert advisors, you can run manual testing for your strategy. However, this process is tougher than when you’re applying automated backtesting. So, only pros can conduct it. 

Let's focus on how you can test an expert advisor on the MetaTrader® platform.

2. Download the suitable historical data for the particular trading instrument you want to test. MetaTrader® platform doesn’t frequently provide complete historical data causing inaccurate results.

You can import these to your dashboard. A sufficient amount of historical data is crucial to conduct proper backtesting and get accurate results.

When you have fulfilled all these prerequisites, you can move to the head testing process.

Step 4. Select The Timeframe

Choose a suitable timeframe and testing model. The date range allows you to test EA's specific timeframes and a specific section of history data. Besides using the date range for testing Expert Advisors, you can use them as a model for testing the bar progression.

You’d select from seven timeframes and three Models. These models are:
