In the first article, we analyzed MQL5 code libraries in detail. We covered different library types, their benefits, creating EX5 libraries, and the components of an EX5 library source code file (.mq5). This gave you a strong foundation in EX5 libraries and their creation process. We then created a practical example of an EX5 Positions Management library, demonstrating how to code exportable functions with MQL5. In this article, we will continue building on that foundation.
