History of MQL5.community development

This time we will create a simple Expert Advisor that will get position properties on the current symbol and display them on the custom info panel during manual trading. The info panel will be created using graphical objects and displayed information will be refreshed at every tick. This is going to be much more convenient than all the time having to manually run the script described in the previous article of the series called "MQL5 Cookbook: Getting Position Properties".

Arrays are an integral part of almost any programming language along with variables and functions. The article should be of interest primarily to novice MQL5 programmers, while experienced programmers will have a good opportunity to summarize and systematize their knowledge.

In this article, we will create a script that gets all position properties and displays them to the user in a dialog box. Upon running the script, you will be able to select out of two modes available in the drop-down list in the external parameters: to either view position properties only on the current symbol or to view position properties on all symbols.

This is the first article of the MQL5 Cookbook series. I will start with simple examples to allow those who are taking their first steps in programming to gradually become familiar with the new language. I remember my first efforts at designing and programming trading systems which I may say was quite difficult, given the fact that it was the first programming language in my life. However, it turned out to be easier than I thought and it only took me a few months before I could develop a fairly complex program.
