Kurtosis Indicator
rev. 01/06/97

The Kurtosis is a market sentiment indicator. The MetaStock formula for the Kurtosis is as follows:

Kurtosis Indicator

Mov(Mov(Mo(3)-Ref(Mo(3),-1),66,E),3,S)

The Kurtosis is constructed from three different parts.
The Kurtosis, the Fast Kurtosis(FK), and the Fast/Slow Kurtosis(FSK).

The Kurtosis(K) portion of this calculation is mo(3)-ref(mo(3),-1).
Which is today's Kurtosis - yesterday's Kurtosis.

The Fast Kurtosis(FK) is mov(K,66,E) mov(mo(3)-ref(mo(3),-1,66,E).
Which is the Kurtosis smoothed with a 66 period exponential movingaverage.

The Fast/Slow Kurtosis(FSK) is the complete formula mov(mov(mo(3)-ref(mo(3),-1),66,E),3,S).
Which is the FK smoothed with 3 period simple moving average.

**You may want to experiment with different time periods to optimize the results.
For example, to calculate a 4 period Kurtosis, a 50 period FK and a10 period FSK, use the following formula:

mov(mov(mo(4)-ref(mo(4),-1),50,E),10,S)

Kurtosis Indicator

KP:= Input("Kurtosis Period -",1,30,3);
FK:= Input("Fast Kurtosis -",1,500,50);
FSK:= Input("Fast/Slow Kurtosis -",1,50,6);
Mov(Mov(Mo(KP)-Ref(Mo(4),-1),FK,E),FSK,S)
