Can-t-find-the-documentation-on-IndicatorBase-CalculatePartialValue

A summary, it's meant to calculate a partial update for streaming charts, that's the only place it's called. And we've only implemented it so far in 3 indicators, RSI, SMA and MFI. You assign the calculated value to the "StreamingValue" property.

Here is a reference implementation used in SMA:

CODE:

        //calculate partial value
        public override bool CalculatePartialValue()
        {
            StreamingValue = Double.NaN;
            TimeSeries source = Parameters[0].AsTimeSeries;
            if (Double.IsNaN(source.StreamingValue))
                return false;
            Int32 period = Parameters[1].AsInt;
            if (period >= source.Count)
                return false;
            double sum = 0;
            for (int n = 0; n < period - 1; n++)
            {
                var i = source.Count - 1 - n;
                sum += source[i];
            }
            sum += source.StreamingValue;
            StreamingValue = sum / period;
            return true;
        }
