Hi,

You can change date time to a numerical unit like Unix time and then use it instead of date time for your statistical models, as I know all time series data uses the date time for x coordinate.

Hi,

This sample cBot might help you:

using cAlgo.API;
using System;
using System.Globalization;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.FullAccess)]
    public class TradeTime : Robot
    {
        private TimeSpan _startTime, _endTime;

        [Parameter("Start Time", DefaultValue = "07:00:00", Group = "Time Filter")]
        public string StartTime { get; set; }

        [Parameter("End Time", DefaultValue = "16:00:00", Group = "Time Filter")]
        public string EndTime { get; set; }

        private DateTime CurrentTime
        {
            get { return Server.TimeInUtc.Add(-Application.UserTimeOffset); }
        }

        private bool IsTimeCorrect
        {
            get { return (_startTime > _endTime && (CurrentTime.TimeOfDay >= _startTime || CurrentTime.TimeOfDay <= _endTime)) || (_startTime < _endTime && (CurrentTime.TimeOfDay >= _startTime && CurrentTime.TimeOfDay <= _endTime)); }
        }

        protected override void OnStart()
        {
            if (!TimeSpan.TryParse(StartTime, CultureInfo.InvariantCulture, out _startTime))
            {
                Print("Invalid start time input");

                Stop();
            }

            if (!TimeSpan.TryParse(EndTime, CultureInfo.InvariantCulture, out _endTime))
            {
                Print("Invalid end time input");

                Stop();
            }
        }

        protected override void OnBar()
        {
            // Return if current time is not in start/end time range
            if (!IsTimeCorrect) return;
        }
    }
}

Please take a look on Server.Time, Server.TimeInUtc, Application.UserTimeOffset, .NET TimeSpan, and DateTime.

If you know the C# basics and cTrader automate API references then you can easily do it.

Hi,

You code is full of errors, please learn the basic of C# before trying to create an indicator or cBot.

You can't start your variable names in C# with a number, this is not allowed, and when you post code please use the code snippet option of editor.

We can't develop your cBot for you, we only can answer questions here.

I made some changes on your cBot code but it still has some errors as I don't had access to some of your variables and I don't know what are those variables.

            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.

Hi,

There is no such a feature right now, if you want not 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.

Thanks

 

You can open a thread on suggestions section, but your request is not that useful because when you back test you know how much data is available and there is no need to call load more history as all your backtest data will be loaded and no more or less, during live market condition its useful because you don't know the exact amount of available data so you can ask to load more if you need more data.

Hi,

There is already several very good free session indicators, you can use those instead of building a new one.

Regarding your code, for adding multiple time zone function you have to use the "Application.UserTimeOffset" and "Application.UserTimeOffsetChanged" for getting user current time zone offset, and then you can convert your indicator Server.Time or bar open times to the user time zone offset by adding the time offset value.

And yes its possible to show a vertical text, you have to use StringBuilder and add each latter as a new line on it.

Getting user time offset example:

using cAlgo.API;

namespace cAlgo
{
    /// <summary>
    /// This sample indicator shows how to use the API Application object nad display its properties data inside a chart control
    /// </summary>
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ApplicationSample : Indicator
    {
        private TextBlock _userTimeOffsetTextBlock, _themeTextBlock;

        [Parameter("Horizontal Alignment", DefaultValue = HorizontalAlignment.Center)]
        public HorizontalAlignment HorizontalAlignment { get; set; }

        [Parameter("Vertical Alignment", DefaultValue = VerticalAlignment.Center)]
        public VerticalAlignment VerticalAlignment { get; set; }

        protected override void Initialize()
        {
            Application.ColorThemeChanged += Application_ColorThemeChanged;
            Application.UserTimeOffsetChanged += Application_UserTimeOffsetChanged;

            DrawApplicationInfo();
        }

        private void Application_UserTimeOffsetChanged(UserTimeOffsetChangedEventArgs obj)
        {
            _userTimeOffsetTextBlock.Text = obj.UserTimeOffset.ToString();
        }

        private void Application_ColorThemeChanged(ColorThemeChangeEventArgs obj)
        {
            _themeTextBlock.Text = obj.ColorTheme.ToString();
        }

        private void DrawApplicationInfo()
        {
            var grid = new Grid(3, 2) 
            {
                BackgroundColor = Color.Goldenrod,
                HorizontalAlignment = HorizontalAlignment,
                VerticalAlignment = VerticalAlignment
            };

            grid.AddChild(new TextBlock 
            {
                Text = "Version",
                Margin = 5
            }, 0, 0);
            grid.AddChild(new TextBlock 
            {
                Text = Application.Version.ToString(),
                Margin = 5
            }, 0, 1);

            grid.AddChild(new TextBlock 
            {
                Text = "Theme",
                Margin = 5
            }, 1, 0);

            _themeTextBlock = new TextBlock 
            {
                Text = Application.ColorTheme.ToString(),
                Margin = 5
            };

            grid.AddChild(_themeTextBlock, 1, 1);

            grid.AddChild(new TextBlock 
            {
                Text = "User Time Offset",
                Margin = 5
            }, 2, 0);

            _userTimeOffsetTextBlock = new TextBlock 
            {
                Text = Application.UserTimeOffset.ToString(),
                Margin = 5
            };

            grid.AddChild(_userTimeOffsetTextBlock, 2, 1);

            Chart.AddControl(grid);
        }

        public override void Calculate(int index)
        {
        }
    }
}

Using StringBuilder:

using cAlgo.API;
using System.Text;

namespace cAlgo
{
    /// <summary>
    /// This sample shows how to use Chart.DrawStaticText method to draw static locked text on chart
    /// </summary>
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ChartStaticTextSample : Indicator
    {
        protected override void Initialize()
        {
            var stringBuilder = new StringBuilder();

            stringBuilder.AppendLine("Symbol: " + SymbolName);
            stringBuilder.AppendLine("TimeFrame: " + TimeFrame);
            stringBuilder.AppendLine("Chart Type: " + Chart.ChartType);

            Chart.DrawStaticText("Static_Sample", stringBuilder.ToString(), VerticalAlignment.Bottom, HorizontalAlignment.Left, Color.Red);
        }

        public override void Calculate(int index)
        {
        }
    }
}

Hello Ahmad,

Thanks for the suggestion. But with your suggested solution if you compare the result through the indicator code (Result[index]) and compare it to the result through the bot (crsi.Result[index]), you'd find that both values still don't match.

And I'm not sure why I'd need to change the indicator code to retrieve a value from indicator to bot, knowing the indicator already produces the correct values for CRSI.

Sameh

There was some issues in your indicator code, that causes issues when you use it on a cBot, like using invalid bar index.

I checked the indicator and cBot I posted and the results does match on backtest for EURUSD on Spotware cTrader beta.

Hi Panagiotis,

This bug can be reproduced with the simplest of bots, and is still present in cTrader 4.0.

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class Bug : Robot
    {

        protected override void OnStart()
        {
            var bars = MarketData.GetBars(TimeFrame.Hour4, "GBPUSD");
            bars.BarOpened += Bars_BarOpened;
        }

        private void Bars_BarOpened(BarOpenedEventArgs obj)
        {
            Print("BarOpened called at {0}", Server.Time);
        }
    }
}

The code above should only produce output on every 4 hour bar, but is executed on every tick instead.  This is the log output:

30/03/2021 23:34:22.614 | cBot "Bug" was stopped for GBPUSD, h4.

This doesn't happen in backtesting, only on a cbot running live.  That fact makes it a particularly nasty surprise, which has already cost me real money.

Hi,

Which broker cTrader you used for the test? I tried on Spotware Beta cTrader and I couldn't replicate the issue.
