Dear trader,

Unfortunately the troubleshooting did not help us reproducing this behavior. Does this still happen in 4.5.1? If yes, can you send us the log?

Hi

Thanks for following up. I submitted a support request via cTrader yesterday which has a link to this thread in it. However, to clarify here, I've updated to 4.5.1 and am still getting the same results.

I even wiped my hard drive and installed a fresh copy of Windows 11, along with everything else and still the same problem.

Sorry if I'm being ignorant but are you referring to the log tab of the backtest? If so, these are the only two entries.

24/10/2022 00:00:00.000 | CBot instance [New cBot, EURUSD, h1] started.
24/10/2022 00:00:00.000 | CBot instance [New cBot, EURUSD, h1] process was unexpectedly terminated.
 

That is from a newly created bot without any changes made to it at all.

I'm guessing you still haven't been able to replicate this? I re-imaged my laptop again this weekend and it's still happening.

I also have the same problem

Hello, I also have the exact same problem. Only .net 4 (legacy) can work with backtesting but not .net 6....I had reinstalled Windows 11 and still same problem. What was the fix for that?

Thanks, appreciate your help!

I've not got a solution yet. I've spent my entire weekend trying to find a fix.

I've reinstalled Windows 11 again this yesterday and it's the same problem. I've also created Hyper-V VMs with Windows 10 Ent, Edu & Pro, as well as Windows 11 Ent, Edu & Pro. Each time both .NET6 and .NET4 bots and indicators work fine in all the Windows 10 VMs, but only the .NET4 bots and indicators work in all the Windows 11 VMs. You can probably appreciate the considerable time out of my weekend that this has taken.

I've contacted Spotware via Telegram, but they probably won't pick it up until tomorrow.

I can only assume, at the moment, that Spotware don't support Windows 11 for cTrader, which needs to be corrected pretty promptly, as a high priority, as all new Windows computers now come with Windows 11 and it is 14 month old OS, especially as it's a Windows only client.

I have another device "Microsoft Surface Go3" with Windows 11 and cTrader works there perfectly with .Net 6. Weird.

What edition of Windows 11 does your Surface Go have? I have a Surface Pro 8 and I have the Education edition. It's the same as the Enterprise but with out App-V I believe

Gets more interesting

If you debug the bot, changing the AccessRights to FullAccess, after running it and you get the Available Debuggers window, click Cancel and the bot will run. Change AccessRights back to the Default of None, and it crashes.

I just built a brand new machine tonight.  Loaded windows 11 and then ctrader.  I imported by bots and indicators.   They build, but they do nothing.

If you press the play button it acts like its going to run the backtest but does not.  Optimization loads threads but never does anything either.

System is Ryzen 9 7900X w 32GB DDR5, 2TB NVME, windows 11 pro.

RE: Same Issue

Hi there,

ever since I installed Windows 11 this has been happening to me. I've had to use .NET 4 for backtesting.

OS: Windows 11 Pro 22H2 (Build: 22621.1265)
cTrader Version: 4.5.9.13513 (ICMarkets)

Using the following code:

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

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.None)]
    public class SimpleTrader : Robot
    {
        [Parameter(DefaultValue = "Hello world!")]
        public string Message { get; set; }

        protected override void OnStart()
        {
            Print("Hello world");
        }

        protected override void OnTick()
        {
            
        }

        protected override void OnStop()
        {
            
        }
    }
}

My output in the console is:

05/02/2023 01:00:00.000 | Indicator instance [Bollinger Bands, EURUSD, Hh4] unloaded.
05/02/2023 01:00:00.000 | Indicator instance [Aroon, EURUSD, Hh4] unloaded.
05/02/2023 01:00:00.000 | Indicator instance [MACD Crossover, EURUSD, Hh4] unloaded.

05/02/2023 01:00:00.000 | CBot instance [SimpleTrader, EURUSD, Hh4] process was unexpectedly terminated.

I have tried everything, but could not get it to work on Windows 11. I have just resorted to compiling in .NET 4, and that still works.

Hoping this issue gets some more attention, glad to see I'm not the only one struggling with this.

Cheers

Hi Don,

Does your cBot reference any indicators?

Hi Panagiotis,

thanks for the reply. No, in an attempt to have a simple "Hello World" program, there are no custom indicators.

The indicator instances in the log are because I had them open on the backtesting chart. Even if I have a clean chart without any indicators on, the cBot process terminates unexpectedly on runtime. Is there a way to provide a detailed log output of what is happening in the background to debug?

Hi Panagiotis,

I am using cTrader version 4.6.4.13909 and I have installed the .NET SDK and set to use it in cTrader's settings.

The following code produces the "process terminated unexpectedly" error:

Hi there Panagiotis,

since there hasn't been much activity on this thread, I just wanted to post a workaround that I discovered whilst searching the forums.

If I set the AccessRights to Full in the cBot, the error is gone and I can compile and run bots using Automate. Hope it helps anyone else that is struggling with this issue.

Don

Thanks Don!  I've been dealing with this almost a month, installing and uninstalling .Net versions with no solution.

This was the only thing that worked!! Now what would the thing that changes from the 4.x that make it works with that change uh?

Thanks again!!
