You have to add Objects.

  int iChartID = ChartID ( );
 
  ObjectCreate (iChartID, "ButtonSell", OBJ_BUTTON, iSubWindow, 0, 0);
  ObjectSetInteger (iChartID, "ButtonSell", OBJPROP_XDISTANCE, 10);
  ObjectSetInteger (iChartID, "ButtonSell", OBJPROP_YDISTANCE, 10);
  ObjectSetInteger (iChartID, "ButtonSell", OBJPROP_XSIZE, 50);
  ObjectSetInteger (iChartID, "ButtonSell", OBJPROP_YSIZE, 25);
  ObjectSetString (iChartID, "ButtonSell", OBJPROP_TEXT, "SELL");
