So I guess it extrapolates the linear regression of the last x bars as a trend line of least squares and uses the end point thereof as current value of the yellow line, then adds envelopes and a kind of bollinger element to represent volatility. Not a bad idea but why not go a little further and project the end of the regression line a few bars into the future and take that as middle line value?
