Thank you for Replay

Function code or utility code

example write text

void WriteText(string nm, string tx, color cl, int xd, int yd, int cr=0, int fs=14 ,string fnt="Arial") {
  if (ObjectFind(0,nm)<0) ObjectCreate(0,nm, OBJ_LABEL, 0, 0,0);
 
 ObjectSetString(0,nm,OBJPROP_TEXT,tx);
 ObjectSetInteger(0,nm,OBJPROP_COLOR,cl);
 ObjectSetString(0,nm,OBJPROP_FONT,fnt);
  ObjectSetInteger(0,nm, OBJPROP_XDISTANCE, xd);
  ObjectSetInteger(0,nm, OBJPROP_YDISTANCE, yd);
  ObjectSetInteger(0,nm, OBJPROP_CORNER   , cr);
  ObjectSetInteger(0,nm, OBJPROP_FONTSIZE , fs);
 
}
