Notes
==============
string mySymbol = StringSubstr(Symbol(),0,6); // In case of m at end for mini account
==============
ObjectCreate(“MyLabel”,OBJ_LABEL, 0, 0, 0 );
ObjectSet    (“MyLabel”,OBJPROP_CORNER, 1);
ObjectSet    (“MyLabel”,OBJPROP_XDISTANCE, 15 );
ObjectSet    (“MyLabel”,OBJPROP_YDISTANCE, 15 );

Then you just set your object text property to the label, size, font and colour you want
ObjectSetText( "MyLabel", "jsfero@otenet.gr"  , 10, "Times New Roman", Yellow ); 

Don’t forget to kill the object at some point (probably in DeInit())
ObjectDelete("MyLabel");
