You need to create a file, a text file can be created,
The file will be located in COMMON_PATH.
You overwrite the file with the data.
On the other terminal, it's the same, but instead of SHAREWRITE you put SHAREREAD

Hello all.
I am a beginner in this field and to me it seems unreal to write any advisors, scripts etc.
Could you, as an experienced user, please advise me what to start working with first, what literature to pay attention to, etc.
I just can't describe in detail what I want to learn, because I know very little about this field.
Thank you in advance!
Start with the simplest scripts and go through them with a debugger to understand the programming language itself. Learn if, for, switch, do statements, function calls with parameters passed. All of this under the debugger.
Then write here again ))
Can you tell me how to select an object when it is created, so that it doesn't lose its selection and doesn't select itself when the user deselects it. It was easy in the fourth, but it doesn't work in the fifth.
It used to be, and it worked just fine:
if(ObjectFind(chart_ID,nm)!=0) {
ObjectCreate(chart_ID,nm,OBJ_HLINE,0,0,0);
ObjectSetInteger(chart_ID,nm,OBJPROP_SELECTED,sel);
...
}
ObjectSetDouble(chart_ID,nm,OBJPROP_PRICE,p);
}
As you can see, when creating, we can select or not select the object being created at once and it will not change anymore and there will be no reference to it, but it doesn't work in the fifth one, it creates it without selection.
How to make mql5 so that the object can be selected at creation and then manually manage it when needed - to select/not to select

How can I make mql5 create an object so that it could be selected and then manipulated manually when necessary - to select/not select an object?
Do the following:
//--- при создании графического объекта функцией ObjectCreate, по умолчанию объект
//--- нельзя выделить и перемещать. Внутри же этого метода параметр selection
//--- по умолчанию равен true, что позволяет выделять и перемещать этот объект
ObjectSetInteger(chart_ID,name,OBJPROP_SELECTABLE,selection);
ObjectSetInteger(chart_ID,name,OBJPROP_SELECTED,selection);
"selection" here should be "true".
