PIVOT FORMULA

["Malcolm Walsh" <malcolm.walsh@xxxxxxx>]

List;
I have been reading "Trading Systems" by  Krutsinger.
Mention is made of the a pivot formula. A Trade Station
code is given which involves the average of the high, 
low and close plus some other arithmetic.

I cannot find a reference anywhere that can explain this
formula or what it's good for.

I am hoping that there is someone who is familiar with
this formula and could give me a brief explanation or
a reference.

Thanks

Malcolm
