Part 1: Getting Started with MQL5 and Your Development Setup
Welcome to the first section of our journey through "Introduction to MQL5 and Development Environment". Here, we’ll dive into the essentials of MQL5, the programming language designed for MetaTrader 5.
If you're coming from MQL4, you'll notice that MQL5 opens up a world of possibilities with its support for object-oriented programming (OOP), much like C++. Now, while some OOP concepts have trickled down to MQL4, for many users, especially those new to coding, OOP can seem a bit daunting.
The aim of this guide is to break down these complexities and make learning MQL5 as straightforward as possible. Think of this book as your trusty sidekick, complementing the MQL5 reference by delving into all aspects of programming while explaining them in detail. Plus, you can choose to stick with either an object-oriented approach or a procedural style—or even mix the two!
If you're already familiar with programming, feel free to skip the introductory bits. For those of you who’ve dabbled in C++, you might find MQL5 a walk in the park. Just keep an eye out for the differences to avoid any hiccups.
With MQL5, you can whip up various types of applications, like indicators that visually display data, Expert Advisors (EAs) to automate your trading, scripts for one-off tasks, and services for running jobs in the background.
What sets MetaTrader 5 apart is the ability to control your entire trading system right from the client terminal. This is where your MQL5 programs will run and send trade commands to the server—rest assured, MQL5 applications don’t get installed on the server itself.
This first part will guide you through editing, compiling, and running your programs. We’ll also cover different data types, variables, expressions, arrays, debugging techniques, and how to output your results effectively.
