hold trendlines after restart bot

30 EUR  Payment method:  Direct Payment

Hi, does anyone know if it is possible to keep chart drawings after restarting a bot?

When I start a bot it automatically draws a trendline right through the chrart until it gets drawn. if I stop the bot and start it again, the trendlines disappear and they are all across the chart again.

this problem does not happen in backtest.

Thank you in advance!

For example:

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

namespace cAlgo.Robots
    [Robot(TimeZone = TimeZones.WEuropeStandardTime, AccessRights = AccessRights.None)]
    public class RS : Robot

        private ChartTrendLine _trendLine1;

        protected override void OnStart()

         _trendLine1 = Chart.DrawTrendLine("High1", Chart.FirstVisibleBarIndex, Chart.BottomY, Chart.LastVisibleBarIndex, Chart.TopY, Color.Red);


        protected override void OnBar()

        protected override void OnTick()
            _trendLine1.IsInteractive = true;
            if (Bars.Last(0).High > Bars.Last(1).High & Bars.Last(1).High > Bars.Last(2).High )

                DateTime x2 = Bars.Last(0).OpenTime;
                DateTime x1 = Bars.Last(10).OpenTime;
                double y1 = Bars.Last(0).High;
                double y2 = Bars.Last(0).High;

                Chart.DrawTrendLine("High1", x1, y1, x2, y2, Color.Red);
