    True Range = Maximum(H-L,H-PDC,PDC-L)

    where:

    H = todays high
    L = todays low
    PDC = previous Days close

    ATR (Average True Range) is the average of TR over a number of days (say 20 days).

    A good explanation of how to use it in conjunction with Money Management is at www.originalturtles.org
