    Description:
    Moving Average & Price Crossover

    Formula Parameters:
    Length : 40

    Notes:
    This is the almost simpliest strategy a trader can imagine. It is
    based on moving average concept. A Moving Average is an indicator
    that shows the average value of a security's price over a period of
    time. When calculating a moving average, a mathematical analysis of
    the security's average value over a predetermined time period is made.
    As the security's price changes, its average price moves up or down.
