Forget what you wrote next. Declare an array of appropriate type at global variable level arr[][][3] and define the second dimension by yourself.

Well, it's like this. And you will probably need to convert string indexes to integers.


THANK YOU VERY MUCH!!!! When one's brain boils, one becomes "blind" and fails to see the simple and obvious things. The most interesting thing is that you know the solution is simple, "like three kopecks", but, alas, it's a blur in front of your eyes.
THANK YOU again !!!!!

You don't need to give stupid advice. This command will remove all objects from the chart altogether.

I do not agree with you!

There was a question:

How to delete all objects such as OBJ_ARROW_RIGHT_PRICE ?

Solution:

ObjectsDeleteAll(0,OBJ_ARROW_RIGHT_PRICE); //удалить все объекты типа "Правая ценовая метка" в главном окне графика

How is the solution stupid?

There was a question:

Solution:

And why is the decision stupid?

By the fact that it will remove ALL objects. Even those that do NOT belong to the EA/indicator. What if a person has been markup his own code on a chart for a long time? And then he ran this code in a third-party indicator? How, and what would he then say about the author of this good code?

Yeah, Vitya... people are mean these days... It's sad.

Actually it all started with command: ObjectsDeleteAll(0,OBJ_ARROW_RIGHT_PRICE) ;

and then another variant tried ObjectsDeleteAll(OBJ_ARROW_RIGHT_PRICE);

Dear Sir, read the help :)

I don't understand why my index with the mentioned commands works correctly in Alpha-Forex, but in Saxo Bank the objects are not deleted anymore.

Then I started experimenting with the script and the script stopped deleting objects in all terminals.

 

Salud to all !

Such an oddity of the tester is observed.

After closing orders 152, 153, 158 and 159 the profit is not correct (as if the tester calculated incorrectly). The orders have been "hanging" for several months as shown in the table. Besides, the drawdown is shown in the table correctly but it is not visible on the chart for some reason.

What can it be ?

Dear Sir, read the help :)

I don't understand why my index with the mentioned commands works correctly in Alpha-Forex, but in Saxo Bank the objects are not deleted anymore.

Then I started experimenting with the script and the script stopped deleting objects in all terminals.

The first looks in the main chart window, the second in all. Conclusion - 1) Use window index to reduce the number of objects the function goes through to find the ones to be deleted. 2) If you delete by name (part of name, because one mql program usually names objects with some personal prefix), then use search loop from last (older by time of creation) object.

Although there is indeed a problem with deleting objects, if there are a lot of them and it goes from 0 to ObjectTotal()-1, then some of the objects are not deleted. Question to developers, maybe there is not enough buffer memory allocated.

Example:

void DeleteObjects(int chartID, string prefix_obj_name) {
   string obj_nm="";
   int obj=ObjectsTotal();
 //  for(int k=0; k<obj; k++){  // неправильный вариант
   for(int k=obj-1; k>=0; k--){
      obj_nm = ObjectName(k);
      if(StringFind(obj_nm,prefix_obj_name)>=0) 
      { 
         ResetLastError();
         if(!ObjectDelete(chartID,obj_nm))
         {
            Print(__FUNCTION__,
            ": не удалось удалить объект ",obj_nm," Код ошибки = ",GetLastError());
         }
      }
   }
}
// prefix_obj_name = "Obj_MQLname_";   Имена объектов создаваемых программой "Obj_MQLname_Close_"+DoubleToStr(Close[0],Digits), "Obj_MQLname_Open_"+DoubleToStr(Open[0],Digits)   и т.д.
 
Can you tell me if Win 8 is compatible with MT 4 and MT 5? I'm asking because I have a mac and am wondering which OS to buy a PC with. One guy even showed me a screenshot of MT 4 running on 8. But since some comrades claim that there is no full compatibility, I have to clarify... Thanks.
