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.
cci 34 and 46 cross 0 from below and later crossed 100 from below. The cross of either 0 from below or 100 from below or the cross of both 0 and 100 is needed for a long trade.
