Indicator Name: Cybernetic Cycle Period (length)
(Cybernetic Analysis)
Function Name: Cybernetic Cycle Period
Format: ExtFml( "ADSI.CyberCyclePeriod", Prices,
alphas, deltaPhaseLows, deltaPhaseHighs)
Input 1: Prices. (suggested input is Median
Price)
Input 2: alphas. The alpha factor "cuts off"
the frequencies which are extracted from price for measuring
the cycle content. It determines a lower bound for the period
length. The higher the alpha, the higher the frequencies used
for cycle measurement. An alpha of 0.18 considers frequencies
at about a cycle length of 11 & above. An alpha of 0.09 considers
frequencies at about a cycle length of 22 & above. An alpha
of .07 considers frequencies at about a cycle length of 28 &
above, and so on. The variable is range bound between 0.0 and
1.0.
Input 3: DeltaPhaseLows. This is a value (in
radians) that determines the an upper bound for the period length.
A lower value allows longer cycles to be measured. For example,
a value of 0.1 only allows cycles less than 63 periods to be
measured.
Input 4: DeltaPhaseHighs. This is a value
(in radians) that determines the a lower bound for the period
length, much like the alphas input. A higher value allows shorter
cycles to be measured. For example, a value of 1.1 only allows
cycles greater than 6 periods to be measured.
