cci 34 and 46 cross 0 from below. Note that it also crossed 100 from below almost at the same time. The crossing of 0 from below is enough of a signal on its own and so too the cross of 100 from below is a signal on its own . However for cci 34 and cci 46 to cross 0 and 100 from below almost at the same time is very good signal.
