Fractals indicator with Alert

Here is the Fractals indicator which I implemented my alert library on it: https://drive.google.com/open?id=11btllj6A4-HV04SEDKvofvdA7F3Cy9YD

using cAlgo.API;
using cAlgo.API.Alert;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, AccessRights = AccessRights.FullAccess)]
    public class Fractals : Indicator
    {
        #region Fields

        private int _lastAlertBar;

        #endregion Fields

        [Parameter(DefaultValue = 5, MinValue = 5)]
        public int Period { get; set; }

        [Parameter("Alert", DefaultValue = true)]
        public bool Alert { get; set; }

        [Output("Up Fractal", Color = Colors.Red, PlotType = PlotType.Points, Thickness = 5)]
        public IndicatorDataSeries UpFractal { get; set; }

        [Output("Down Fractal", Color = Colors.Blue, PlotType = PlotType.Points, Thickness = 5)]
        public IndicatorDataSeries DownFractal { get; set; }

        public override void Calculate(int index)
        {
            if (index < Period)
                return;

            DrawUpFractal(index);
            DrawDownFractal(index);

            cAlgo.API.Alert.Models.Configuration.Current.Tracer = Print;
        }

        private void DrawUpFractal(int index)
        {
            int period = Period % 2 == 0 ? Period - 1 : Period;
            int middleIndex = index - period / 2;
            double middleValue = MarketSeries.High[middleIndex];

            bool up = true;

            for (int i = 0; i < period; i++)
            {
                if (middleValue < MarketSeries.High[index - i])
                {
                    up = false;
                    break;
                }
            }
            if (up)
            {
                UpFractal[middleIndex] = middleValue;

                TriggerAlert(index, TradeType.Sell);
            }
        }

        private void DrawDownFractal(int index)
        {
            int period = Period % 2 == 0 ? Period - 1 : Period;
            int middleIndex = index - period / 2;
            double middleValue = MarketSeries.Low[middleIndex];
            bool down = true;

            for (int i = 0; i < period; i++)
            {
                if (middleValue > MarketSeries.Low[index - i])
                {
                    down = false;
                    break;
                }
            }
            if (down)
            {
                DownFractal[middleIndex] = middleValue;

                TriggerAlert(index, TradeType.Buy);
            }
        }

        private void TriggerAlert(int index, TradeType tradeType)
        {
            if (!IsLastBar || index == _lastAlertBar || !Alert)
            {
                return;
            }

            _lastAlertBar = index;

            string comment = tradeType == TradeType.Buy ? "Up" : "Down";

            Notifications.ShowPopup(TimeFrame, Symbol, tradeType, "Fractals");
        }
    }
}

The code isn't written by me, I just added the alerting part.
