Example
This example illustrates how to plot and call the CrossUnderValueBar series. The entry is made when CCI(Bars, 14) has crossed under value 100 within last 3 bars, and it is still currently under value 100:

CCI cci = CCI.Series( Bars, 14 );
int val = 100;
CrossUnderValueBar xub = CrossUnderValueBar.Series( cci, val );
SetBarColors( Color.Silver, Color.Silver );
for (int bar = xub.FirstValidValue; bar < Bars.Count; bar++)
{
if( xubbar == bar )
SetBarColor( bar, Color.Red );
if (IsLastPositionActive)
{
SellAtStop( bar+1, LastPosition, Lowest.Series( Low, 20 )bar );
}
else
{
if( ( ccibar < val ) & ( xubbar > bar - 3 ) )
BuyAtMarket( bar+1 );
}
}
