Back-testing with Historical Data

Using historical data is crucial to understand past performance. MQL5 Tester allows users to download high-quality historical data for accurate testing.

Historical Data Quality

Consider the following when choosing historical data:

• Data Source: Official exchange data is more reliable.
• Timeframe: Higher timeframes usually have more accurate data.
• Tick Volume: The number of changes in price during a particular bar.

Visual Back-testing

Visual back-testing lets you observe an EA's performance on historical data in real-time.

Optimizing an EA with MQL5 Tester

Optimization is a process that can maximize the efficiency of an EA by testing different input configurations and providing the best set of parameters for a specific period.

Choosing Optimization Criteria

• Balance Max: Focuses on the highest final balance.
• Sharpe Ratio: Seeks risk-adjusted returns.
