use enum in IF?

Greetings all -- I am trying to learn how things work here, and could use some help, please.

I have done the following: Created an enum. Created a parameter that allows the selction of the enum.

Defined basic OHLC, and created an IF to plot a dot if (the IF) is satisfied...

What I want is to have the argument in the IF stand in for the actual enum - so that selecting the enum in the parameter will casue the IF to evaluate the defined variables, and if true, to plot a dot. Everything works but the if/enum business.

I am sure that ther is some basic aspect of C# I am violating or don't understand, so any help would be greatly appreciated!

Here is the code:

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;


namespace cAlgo
{
    [Indicator("Test00", IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class CT_BarColor : Indicator
    {
        public enum FormationType
        {
            UpClose,
            DownClose
        }


        [Parameter("BarColor")]
        public FormationType BarColor { get; set; }

        [Parameter("V Spacing Text", DefaultValue = 6, MinValue = 0, Step = 0.1)]
        public double V_space { get; set; }

        [Parameter("H Spacing Text", DefaultValue = 1.5, MinValue = 0, Step = 0.1)]
        public double H_space { get; set; }

        [Parameter("Dot Spacing", DefaultValue = 8, MinValue = 0, Step = 0.1)]
        public int DotSpacing { get; set; }

        [Output("Dot Above", LineColor = "#FD6341", PlotType = PlotType.Points, Thickness = 7)]
        public IndicatorDataSeries DotAbove { get; set; }

        [Output("Dot Below", LineColor = "#008000", PlotType = PlotType.Points, Thickness = 7)]
        public IndicatorDataSeries DotBelow { get; set; }


        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }


        public override void Calculate(int index)
        {

            double Open = MarketSeries.Open[index];
            double High = MarketSeries.High[index];
            double Low = MarketSeries.Low[index];
            double Close = MarketSeries.Close[index];

            bool DownClose = Close < Open;
            bool UpClose = Close > Open;

            ///This below works  -- But this is where I want the argument for the IF (currently DownClose), to grab the selected enum ///from the above parameter.
            ///i.e. I want it to be: if (BarColor) {}, so that (BarColor) returns whatever has been selected in the parameter
            
            if (DownClose)
            {
                DotAbove[index] = High + (DotSpacing * Symbol.PipSize);
            }

        }

    }
}
