Your First Script
Overview In MQL5, a script is a simple program designed to perform a single action and then terminate. Unlike Expert Advisors (EAs), which run continuously with every new market tick, a script executes its code only once when launched. Scripts are ideal for quick operations such as sending a message to the log, closing all trades, or performing calculations that do not require constant updates. This section will guide you through creating and running your first MQL5 script. What You Will Be Able to Do Code Example Execution Steps Key Point Scripts always begin execution with the OnStart() function and stop automatically once the code inside it finishes. They are best suited for one-time tasks, such as modifying trade positions, exporting data, or testing short pieces of code. As you progress, you’ll find scripts useful for both learning MQL5 and performing small maintenance operations in your trading workflow. Next Section→ Next: Understanding Print
