Yevhenii Levchenko:
How do I know if an order was closed manually or by a robot?

DEAL_OUT... 'manually' the robot will have ID=magic

If you search with a robot, then magic = 0 for a manual exit order (although a robot can also have 0, but this is more of an exception than a rule)

 
Vitaly Muzichenko:

Screenshot please, never seen a mark in the logbook as the closure/deletion happened

Thank you, I will have to pay attention to that for general development.

 

Why does this code draw the wrong arrows - MQL5

void ArrowCreate(ENUM_OBJECT             type,
                 datetime                time,
                 double                  price)
  {
   
   string name = (type == OBJ_ARROW_UP ? "Arrow Up №"+(string)(up+1) : "Arrow Down №"+(string)(down+1));
   if(type == OBJ_ARROW_UP)  { up++; }
   else                      { down++; };
   
   ResetLastError();
   if(ObjectCreate(ChartID(),name,OBJ_ARROW,0,time,price))
     {
      ObjectSetInteger(ChartID(),name,OBJPROP_ARROWCODE,(type == OBJ_ARROW_UP ? 241 : 242));
     }
   else
     {
      Print(__FUNCTION__,
            ": не удалось создать знак \"Стрелка\"! Код ошибки = ",GetLastError()); return;
     };
   ObjectSetInteger(ChartID(),name,OBJPROP_ANCHOR,(type == OBJ_ARROW_UP ? ANCHOR_TOP : ANCHOR_BOTTOM)); 
   ObjectSetInteger(ChartID(),name,OBJPROP_COLOR,(type == OBJ_ARROW_UP ? a_color_buy : a_color_sell));
   ObjectSetInteger(ChartID(),name,OBJPROP_STYLE,STYLE_SOLID); 
   ObjectSetInteger(ChartID(),name,OBJPROP_WIDTH,a_size); 
   ObjectSetInteger(ChartID(),name,OBJPROP_BACK,false); 
   ObjectSetInteger(ChartID(),name,OBJPROP_SELECTABLE,false); 
   ObjectSetInteger(ChartID(),name,OBJPROP_SELECTED,false); 
   ObjectSetInteger(ChartID(),name,OBJPROP_HIDDEN,true); 
   ObjectSetInteger(ChartID(),name,OBJPROP_ZORDER,0);
  }


It should draw OBJPROP_ARROWCODE 241 or 242
... but instead it draws normal OBJ_ARROW_UP or OBJ_ARROW_DOWN

 
Sergey Likho:

Can MQL4/MQL5 be used to stretch a BMP image to the whole screen?

As far as I know - no.

It should draw OBJPROP_ARROWCODE 241 or 242
... but instead it draws the usual OBJ_ARROW_UP or OBJ_ARROW_DOWN

Replace

      ObjectSetInteger(ChartID(),name,OBJPROP_ARROWCODE,(type == OBJ_ARROW_UP ? 241 : 242));

to

      ObjectSetInteger(ChartID(),name,OBJPROP_ARROWCODE,(type == OBJ_ARROW_UP ? 225 : 226));

and check - so what is actually drawn?

 
Vladimir Karputov:

these arrows are drawn, but why aren't the arrows coded 241 and 242 drawn?

Thanks! But it's on mt5...

in the Expert Advisors tab this means

Is there any way to get it out programmatically?
 
Igor Makanu:

I did not do it, or rather I did not search for it in the subwindow. In the KB I have laid out an example of clicking on the main window bars and displaying information about the bar - you can look it up

i have made an indicator for experimenting with the buttons - i checked if the buttons move the indicator line

to see if the indicator is moving put a horizontal line in the indicator subwindow ... that's pretty cool ))))

Thanks. Just don't understand how to attach this to my indicator.

 
Yevhenii Levchenko:
software can weed this out?

Then perhaps, as already suggested, by magicka
