    Description:
    CCI Strategy

    Formula Parameters:
    Slow moving average length 10
    Fast moving average length 20


    Notes:
    The Commodity Channel Index (CCI) is best used with markets that display cyclical or
    seasonal characteristics, and is formulated to detect the beginning and ending of these
    cycles by incorporating a moving average together with a divisor that reflects both possible
    and actual trading ranges. The final index measures the deviation from normal, which indicates
    major changes in market trend.

    To put it simply, the Commodity Channel Index (CCI) value shows how the instrument is trading
    relative to its mean (average) price. When the CCI value is high, it means that the prices are
    high compared to the average price; when the CCI value is down, it means that the prices are low
    compared to the average price. The CCI value usually does not fall outside the -300 to 300 range
    and, in fact, is usually in the -100 to 100 range.
