//
//  An interesting phenomena of the %R indicator is its uncanny ability to
//  anticipate a
//
//  reversal in the security's price. The indicator almost always forms a peak
//  an turns
//
//  down a few days before the security's price peaks and turns down. Likewise,
//  %R
//
//  usually creates a trough and turns up a few days before the security's
//  price
//
//  turns up.
