I don't remember where I found this code but I think it does what you
want.


//period is an array

function varPeriodRSI( priceField, period )
{
  Chg = priceField - Ref( priceField, -1 );
  pc = Max( Chg, 0 );
  nc = Max( -Chg, 0 );

  pa = AMA( pc, 1/period );
  na = AMA( nc, 1/period );

  return 100 * pa / ( pa + na );
}
