mql5

In the preceding article of this series, we delved into the process of sending chart snapshots with captions from MetaTrader 5 to Telegram. Our approach, while effective, was rather straightforward and somewhat inflexible. We chained together the components necessary to capture a screenshot, convert or encode it into a message-friendly form, and send it along to Telegram. Although this setup worked, it resulted in a fair bit of code that was repetitive and not all that manageable. So, what can we do to improve this implementation? Move to a more modular codebase! This is the first step toward both a more flexible and a more maintainable system.

In this fourth part of our series, we will focus on enhancing the reusability of our program through code modularization. We will undertake a detailed discussion on the principles of code modularization and, more specifically, how these principles apply to our project. Following that, we will present step-by-step instructions for reorganizing our existing mql5 script into separate, well-defined functions. In the end, you will have the choice of using the old, monolithic program or a new, modular Expert Advisor (EA) with the same output.
