    Defined by J. Welles Wilder, Jr. in 1978 in his book *"New Concepts in
    Technical Trading Systems"* for the RSI

    SAR stands for *Stop and Reverse* and the indicator was meant as a signal
    for entry (and reverse)

    How to select the 1st signal is left unspecified in the book and the
    increase/decrease of bars
