fractal indicator

            var perviousFractalUp = IFractals.UpFractal.Last(1);
            var currentFractalUp = IFractals.UpFractal.Last(0);
            var perviousFractalDown = IFractals.DownFractal.Last(1);
            var currentFractalDown = IFractals.DownFractal.Last(0);

I want to get the first fractal and the second fractal values, how can I do that? that is to separate the value of the first fractal from the value of the second fractal.
