Is this an mql5 bug?

[abbeysworld]

I recently tried to make Xupypr ea object oriented by attaching classes that perform trade executions. I found out that the initial optimization without the object oriented approach worked well. The results were good. Then, I proceeded by enabling the objects and it failed to achieve the former result. I thought this might be a result of programming error, then I stripped all the code from the attached class and still I got the same poor result. Could this be a bug or am I missing something?

Every class must have a constructor. See the article The Order of Object Creation and Destruction in MQL5

Here is the updated version with a constructor and destructor added. The results of an ea should not change when you add an object that "does nothing"
