From Basic to Intermediate: Object Events (I) for MetaTrader 5
In this article, we will look at three of the six events that MetaTrader 5 can generate when some change occurs to an object on the chart. These events are very useful from the standpoint of user interaction. This is because, without understanding these events, we would have to put in much more
From Basic to Intermediate: Objects (III) for MetaTrader 5
In today's article, we will look at how to implement a very attractive and interesting interaction system, especially for those who are just beginning to practice programming in MQL5. There is nothing fundamentally new here. Thanks to my approach to the topic, it will be much easier to understand
From Basic to Intermediate: Handling Mouse Events for MetaTrader 5
This article belongs to the category of materials where simply looking through and studying the code is definitely not enough to understand the processes involved. In fact, you need to create an executable application and run it on any chart. This is done so that you can understand small details
From Basic to Intermediate: Function Pointers for MetaTrader 5
You have probably already heard about pointers when it comes to programming. But did you know that we can use this kind of data here in MQL5? Of course, this must be done in a way that keeps us in control and avoids strange program behavior during execution. Still, because this is a feature with a
From Basic to Intermediate: Objects (II) for MetaTrader 5
In today's article, we will look at how to control some object properties in a simple way using code. We will also see how a custom application can place more than one object on the same chart. In addition, we will begin to understand the importance of assigning a short name to any indicator we plan
From Basic to Intermediate: Objects (I) for MetaTrader 5
In this article, we will begin looking at how to work with objects directly on the chart. This is done using code specially developed for demonstration purposes. Working with objects is very interesting and can be a lot of fun. Since this will be our first contact with the topic, we will start with
From Basic to Intermediate: Indicator (V) for MetaTrader 5
In this article, we will look at how to handle user requests to change the chart plotting mode. This is necessary so that an indicator designed for the current chart plotting mode does not look strange or differ from what a MetaTrader 5 user expects
From Basic to Intermediate: Inheritance for MetaTrader 5
No doubt, this article will require a significant amount of your time to understand how and why the materials described here work. This is because everything that will be shown here is initially oriented toward object-oriented programming, but in fact it is based on the principles of structured
From Basic to Intermediate: Struct (VII) for MetaTrader 5
In today's article, we will show how to approach solving problems related to structuring different elements and creating simpler and more attractive solutions. Although the content is oriented toward learning and, therefore, does not constitute production code, it is essential to thoroughly
From Basic to Intermediate: Struct (VI) for MetaTrader 5
In this article, we will explore how to approach the implementation of a common structural code base. The goal is to reduce the programming workload and leverage the full potential of the programming language itself—in this case, MQL5
