//  Definition: For a variable X, the difference of two cascade values of X,
//
//  devided by their sum.
//
//  For scaling purposes,this quotient may be multiplied by a numerical
//  coefficient.
//
//  Example:
//
//  The Relative Slope of exponential moving average of "typical price"
//
//  A variable independent of specific stock values, usually in the range
//
//  -10<RS<10
//
//  with peaks and troughs almost eliminating the lag between close and
//
//  smoothing average.
//
//  As an indicator, it presents excellent divergences with close graph,
//  anticipating
//
//  trend reversals.
//
//  It is also valuable for classification of stocks, according to their
//  maximum and minimum
//
//  RS values.
