Jerome,
Built-in CCI does not work with variable
period.
You would need to re-implement it using loops or
using other functions that
are variable-period enabled to have variable-period
version.
function MeanDev( array, mean, range )
{
result =
0;
for( i = LastValue( range ) ; i <
BarCount; i++ )
{
result[ i ] = 0;
// the mean
is not 'moving' over the range (outside the loop)
tm = mean[ i ];
for( j = 0; j < range[ i ] AND ( i - j ) >= 0 AND ( i - j ) < BarCount; j++ )
{
result[ i ] = result[ i ] +
abs( array[ i - j ] - tm );
}
result[ i ] = result[ i
]/range[ i ];
}
return result;
}
function VarCCI( array, period )
{
SMATP = MA(array,period );//1,2
MD = MeanDev( array, SMATP, period );
CCIx = (Avg - SMATP) / (0.015 * MD);
return CCIx;
}
n = 20 + 4 * sin( Cum(1) ); //
variable period
Plot(VarCCI(Avg, n),"CCIx",colorGreen,styleLine);
//Plot(CCI(n),"CCI",colorRed,styleLine);
Best regards,
Tomasz
