Re: Stochastic and %R Williams

[MLRobb@xxxx]

Suppose, one wanted to plot an indicator of Stochastics displaying 
(3) three seperate lines; 3,3,3 i.e. (or any other combination [may 
fractions be utilized? decimalized?]):

But, let it display along the 0 to 101 scale (preferably including 
enough decimal places to pivot and settle ties);

Could that be done, in AFL?
