    Description:
    CMO (Chande Momentum Oscillator)

    Formula Parameters:
    Length : 9
    TopBand : 70
    LowBand : -70


    Notes:
    This indicator plots Chandre Momentum Oscillator. This indicator was
    developed by Tushar Chande. A scientist, an inventor, and a respected
    trading system developer, Mr. Chande developed the CMO to capture what
    he calls "pure momentum". For more definitive information on the CMO and
    other indicators we recommend the book The New Technical Trader by Tushar
    Chande and Stanley Kroll.
    The CMO is closely related to, yet unique from, other momentum oriented
    indicators such as Relative Strength Index, Stochastic, Rate-of-Change,
    etc. It is most closely related to Welles Wilder`s RSI, yet it differs
    in several ways:
    - It uses data for both up days and down days in the numerator, thereby
    directly measuring momentum;
    - The calculations are applied on unsmoothed data. Therefore, short-term
    extreme movements in price are not hidden. Once calculated, smoothing
    can be applied to the CMO, if desired;
    - The scale is bounded between +100 and -100, thereby allowing you to
    clearly see changes in net momentum using the 0 level. The bounded scale
    also allows you to conveniently compare values across different securities.
