Angle of the trendline

Hi Support

I have a test cbot and I'm looking how to assign trend angle into variable, but I can see any property to do that.

Can you please let me know if it possible to assign a trend angle into variable?

If not, can you please advice how trend angle is calculated so I can create a method myself?

Please see my code below

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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }
        
        double myangle;


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

        public override void Calculate(int index)
        {
            ChartTrendLine tl = Chart.DrawTrendLine("trendline", Bars.OpenTimes.Last(10), Bars.OpenPrices.Last(10), Bars.OpenTimes.Last(1), Bars.OpenPrices.Last(1), Color.White);
            tl.ShowAngle;

        }
    }
}
