When it happens that an OBJ_BUTTON (OBJPROP_ZORDER == 100) is above a trade level,
pressing the button will not trigger CHARTEVENT_OBJECT_CLICK in case one presses exactly
at the position where the trade level is located.
Is there a workaround to make the OnChartEvent handler also respond to action,
even if one presses the button exactly at the position where the trade level is?
