Hello Panagiotis,

It's the same code from yesterday I am working with which I am testing over several platforms, they work on all just that one gives the error.

Best regards, Bjorn.

Code:


using System;
using System.Linq;
using System.Text;
using cAlgo.API;
namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class DayTradeG1 : Robot
    {

        public int NewsHour { get; set; }

        public int NewsMinute { get; set; }

Hi Bjorn,

I ran the cBot for some time but could not reproduce the issue. Do you still get this exception or was it something temporary? If yes, can you please provide us with the exact steps you follow to reproduce this problem?

Best Regards,

Panagiotis
