We plant add chart objects to backtesting in the future. Currently all chart objects are ignored in backtesting.

It seems everything to do with drawing is disabled during backtest, when drawing becomes a feature it would be handy to have a toggle for it, so the user can turn them back off for speed.

Can you use the chart Object in backtesting yet? Users have been asking for that for 6 years.

Hi lec0456,

Yes you can and you can use in conjunction with visual backtesting as well.

Best Regards,

I tried sing this line of code in my cBot at the point it takes an action:

ChartObjects.DrawVerticalLine("vLine"+OnBarIndex, (int)OnBarIndex, Colors.Red, 1, LineStyle.Solid);

It does not place a line on the backtest chart.

How do I do it?

Hi lec0456,

Here is an example

using System;
using System.Collections.Generic;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            ChartObjects.DrawHorizontalLine("Test", Symbol.Bid, Colors.Red);
        }

        protected override void OnTick()
        {
        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

and here is what you should see on the chart

Make sure you are using Visual Mode.

Best Regards,

Use Spotware Beta

It would be nice if you could select the directory for the Backtest Data so that you could use the the Beta release to backtest data from different brokers. I could probalbly manually copy in the data into the tick directory but it would be too cumbersome.  but thanks for letting me know this is soon to be available.  its a very important and nice feature.
