Hi,

There is no such a feature right now, if you don't want to receive OnTick/Bar events then you can just set a Boolean flag based on your pause condition and ignore the events.

Thanks for the answer, but I don't want to lose these events, I want to wait for user action (e.g. mouse click on the chart) and then process onTick/Bar events

You don't have to, just use a boolean flag to disable/enable the events whenever you need.

Sorry I probably missing the point, how can I disable/enable the events?

This sample might help you:

using cAlgo.API;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class PauseEvents : Robot
    {
        private bool _isPaused;

        protected override void OnStart()
        {
            Chart.MouseDown += Chart_MouseDown;
        }

        private void Chart_MouseDown(ChartMouseEventArgs obj)
        {
            if (obj.ShiftKey)
            {
                _isPaused = true;

                Print("Events paused");
            }
            else if (obj.CtrlKey)
            {
                _isPaused = false;

                Print("Events running");
            }
        }

        protected override void OnTick()
        {
            if (_isPaused) return;
        }

        protected override void OnBar()
        {
            if (_isPaused) return;
        }
    }
}

If you press shift + click then it will pause the OnTick/Bar, and if you press Ctrl + Click then it will allow the code on OnTick/Bar after is pause check to execute.

it is not working, just printed log, I have deleted onBar or Ontick to test. what else do I need to do

Hi,

The above sample only disables OnTick/OnBar, it doesn't pause back tester.

RE: RE: RE:

I think there's no way to pause. Best you can do is to put the below line.

if (IsBacktesting)
{
    throw new Exception("THIS HAS TO STOP");
}

or

if (IsBacktesting)
{
    Print("Stopping here");
    Stop();
}

The only viable way to pause a cBot runtime during backtesting (mainly visual mode) is using windows forms.

        public void Pause()
        {
            if (!IsDebugEnabled) return;
            Print("[DEBUG] pausing the cBot runtime.");
            var result = System.Windows.Forms.MessageBox.Show("Do you want to continue?", "Confirmation", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);

            if (result == DialogResult.OK)
            {
                Print("[DEBUG] resuming the cBot runtime.");
            }
            else
            {
                Stop();
            }
        }

You also need to enable windows forms in the dotnet solution 

<Project Sdk="Microsoft.NET.Sdk">
 <PropertyGroup>
   <TargetFramework>net6.0-windows</TargetFramework>
   <UseWindowsForms>true</UseWindowsForms>
 </PropertyGroup>
 <ItemGroup>
   <PackageReference Include="cTrader.Automate" Version="1.*" />
 </ItemGroup>
</Project>

and use dotnet sdk for compiling the cBot instead of embedded compiler. You can do that in cTrader settings→Automate→Select Compiler
