        Exponential Moving Average Envelope (EMA Envelope) is a trend-based indicator that plots two Exponential Moving Averages (EMAs) as upper and lower bands over a price chart. The bands can be used as oversold and overbought levels respectively.

        InputDescription
        LengthThe number of periods the indicator uses to calculate the EMAs
        DisplaceThe number of bars the indicator to be shifted to
        PercentAboveThe percentage the EMA to be shifted upward
        PercentBelowThe percentage the EMA to be shifted downward
        PriceAbove
        The following data sources are available for calculation of the UppedBand:
        • Open. The Open Price of every bar for the specified period.
        • High. The High Price of every bar for the specified period.

        • Typical. The sum of High, Low, and Close prices divided by 3 for the specified period - (High + Low + Close) / 3.
        • OHLC average. The arithmetical mean of High, Low, Open, and Close prices for the specified period - (Open + High + Low + Close) / 4.
