MQL5 Programming Basics: Tools, Program Types, and First Steps
Summary
This beginner guide introduces the concepts and tools needed to start programming in MQL5. It defines basic computer terms, explains the roles of an editor, compiler, debugger, version control system, and integrated development environment, then compares the four main MetaTrader program types: scripts, indicators, Expert Advisors, and services. The comparison focuses on where programs run, how they respond to ticks and events, whether they can trade, and how their lifecycles differ.
The later material introduces functions and demonstrates a simple script that writes output to a log. It explains that program types use different predefined entry points, and suggests small experiments with generated program templates to learn their startup behavior. The article is instructional rather than a trading method: it helps readers understand the development environment and MQL5 application structure. Its descriptions are introductory, and the suggested experiments are useful for checking platform behavior as the reader progresses.
Key ideas
- MQL5 development typically uses an editor, compiler, debugger, and version control tools within an IDE.
- Scripts, indicators, Expert Advisors, and services differ in lifecycle, event handling, and trading capabilities.
- MQL5 programs rely on predefined entry functions that determine when their logic runs.
- A small script that prints to the log provides an initial way to practice compiling and running code.
- Creating other program types with the wizard can help learners explore their startup behavior.
