Introduction to MQL5 (Part 5): A Beginner's Guide to Array Functions in MQL5

Part 5 of our series will introduce you to the fascinating world of MQL5, designed especially for complete novices looking for a gentle introduction to the intricacies of array functions. This section aims to dismantle the misconceptions that are frequently associated with array functions, guaranteeing that each line of code is not only understood but comprehended thoroughly. Regardless of prior coding experience, I sincerely believe that everyone should have the opportunity to learn about the MQL5 language, which is why I will always be committed to creating an inclusive environment.

In this article, simplicity and clarity are the primary themes. I want to serve as a conduit for people who are curious about coding and the uncharted territory of it. Though they can be confusing at first, I intend to walk you through each array function one line at a time so that you have a fun and educational learning experience. Together, we will solve the puzzles surrounding array functions and equip you with the knowledge necessary to successfully negotiate the complex world of algorithmic trading. This isn't just an article—it's an invitation to go on an amazing journey of coding transformation.

Master MQL5 from beginner to pro (Part I): Getting started with programming

I sometimes receive private messages from those who want to learn how to create their own Expert Advisors or indicators. Although there is a lot of material on this site and on the Internet in general, including very good resources with examples, beginners still need help. Some users seek more consistency in presentation, others require clarity or something else. Sometimes users ask: "Add comments to the code of a working Expert Advisor, I will understand everything and make the same one myself!" But, after they see a hundred lines of code, they get scared, confused and give up the idea. Instead, they say: "Better create an Expert Advisor for me."

Anyway, there are people who still want to "understand everything". This is when a step-by-step guide, explaining things from simple to complex, may come in handy. Well, users can't find such a step-by-step guide for the MQL5 language.

I am starting this series of articles specifically for beginners, for those who are encountering programming for the first time and are willing to learn it. These articles are intended for traders who no longer want to depend on programmers and wish to understand how everything works. The articles offer consistent and detailed information, with pictures and examples, guiding readers to the level of "MQL5 language proficiency".
