Still getting error

Hi,

I am still getting the error. I am sharing the source code. Could you please try this on your end? It got 2 params, EventHours and  EventMins. If an economic event in an econimic calender is AT 16:30, The hours param will be 16 and the mins will be 30. Basically I am trying to execute an order at the same time market data in the economic calender is released. You can look at follwong calender for economic events

Hi prasanthtp,

As pointed out in our previous post, we need to arrange a TeamViewer session to investigate this on your pc.

Hi prasanthtp,

Our team has investigated your issue and here are our suggestions

1. Don't use Thread.Sleep(). Use Timer instead of it.
2. Don't use Environment.Exit(0) - it kills the cBot process. Use the Stop() function.

Find a code example below

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;
using System.Threading;

namespace cAlgo.Robots
{
    /*
    1) Don't use Thread.Sleep(). Use Timer instead of it
    2) Don't use Environment.Exit(0) - it kills cBot process. Use the `Stop()` function.
    */
    [Robot(AccessRights = AccessRights.None)]
    public class issue_40281 : Robot
    {
        [Parameter("Event Hours (24HR format)", Group = "WebSite")]
        public int EventHours { get; set; }
        [Parameter("Event Mins", Group = "WebSite")]
        public int EventMins { get; set; }

        public bool showMessage = true;

        protected override void OnStart()
        {
            var economicEventTime = DateTime.Now.Date.AddHours(EventHours).AddMinutes(EventMins);
            ShowMessage("Current Local Time : " + DateTime.Now.ToString());
            ShowMessage("Economic news Local Time : " + economicEventTime.ToString());


            /*
            you can also use event `TimerTick` to handle it in custom event handler instead of embedded OnTimer callback.
            
            Timer.TimerTick += OnTimerTick;

            private void OnTimerTick()
            {
            }
            */

            if (DateTime.Now < economicEventTime)
                Timer.Start((int)economicEventTime.Subtract(DateTime.Now).TotalSeconds);
        }


        protected override void OnTimer()
        {
            Print("OnTimer");
            Timer.Stop();
            var ExecutResult = ExecuteMarketOrder(TradeType.Sell, "AUDUSD", 5000, Guid.NewGuid().ToString(), null, 20);
        }


        protected override void OnException(Exception exception)
        {
            ShowMessage("OnException: " + exception.Message);

            if ((exception.InnerException != null))
                ShowMessage("OnException Inner: " + exception.InnerException.Message);
            Stop();

        }
        protected override void OnError(Error error)
        {

            ShowMessage("Error :" + error.ToString());

            ShowMessage("Error Code:" + error.Code.ToString());
            Stop();
        }

        private void ShowMessage(string message)
        {
            if (showMessage)
                Print(message);
        }
    }
