I could build it now without any warnings or Failures with this version:

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

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class DrawdownRecorder : Robot
    {
        [Parameter(DefaultValue = 24)]
        public int RecordingInterval { get; set; }

        private double _previousHighWaterMark;
        private DateTime _lastRecordTime;
        private string _drawdownLabel;

        protected override void OnStart()
        {
            _previousHighWaterMark = Account.Equity;
            _lastRecordTime = Server.Time;
            _drawdownLabel = "Drawdown";
        }

        protected override void OnTick()
        {
            if (Server.Time.Hour == 0 && Server.Time.Minute == 0 && Server.Time.Second == 0)
            {
                _lastRecordTime = Server.Time;
                _previousHighWaterMark = Account.Equity;
            }
            else if ((Server.Time - _lastRecordTime).TotalHours >= RecordingInterval)
            {
                double currentEquity = Account.Equity;
                double drawdown = _previousHighWaterMark - currentEquity;
                _previousHighWaterMark = Math.Max(_previousHighWaterMark, currentEquity);

                Chart.RemoveObject(_drawdownLabel);
                Chart.DrawStaticText(_drawdownLabel, "24 hour Drawdown : " + drawdown, VerticalAlignment.Top, HorizontalAlignment.Right, Color.Yellow);
                _lastRecordTime = Server.Time;
            }
        }
    }
}

But when I start it nothing is displayed on the Chart :(
