Topic: Declare Shadows

Hello
is it the right way to declare The lower Shadows !!

var adLshadow = new double[Bars];

            const int firstBar = 1;

            for (int bar = firstBar; bar < Bars; bar++)
            {
                adLshadow[bar] = Math.Min(Open[bar - 1], Close[bar - 1]) - Low[bar - 1];
            }
