How to refresh Line and Text objects upon opening/closing orders?

New comment
 

My EA is set to EachTick, but my objects does not update values/location when orders gets opend or closed.

my code structure as following:

int init()
{
WindowRedraw();
ObjectDelete ("MyLine");
}

int deinit()
{
WindowRedraw();
ObjectDelete ("MyLine");
}

int start()
{
WindowRedraw();
ObjectCreate ( "MyLine", OBJ_HLINE, 0, 0, MyLine_Value );
ObjectSet ( "MyLine", OBJPROP_STYLE, STYLE_SOLID );
ObjectSet ( "MyLine", OBJPROP_COLOR, Blue );
ObjectSet ( "MyLine", OBJPROP_WIDTH, 2 );
string MyLine_Text = DoubleToStr ( MyLine_Value,Digits );
ObjectSetText ( "MyLine", MyLine_Text+" << MyLine_Value", 8, NULL, Black );
}

Please Help and advice.

Hints:

1) MyLine_Value and its label MyLine_Text shall be updated upon closing existing order or opening new order.

2) MyLine_Value is a local variable calculated within the start() function, so that, I can not move the ObjectCreate(....) command into the init() function.

If you create and Object and then try and create it again it fails because the Object already exists . . . if it exists (ObjectFind() > -1) move it to the new position using ObjectSet() or ObjectMove()
