RE:

I agree with this request. When the number of bots or indicators grows beyond a certain number it becomes very cumbersome to navigate the list of bots and to look up things.
An alternative or addition to the original request:
-- The possibility to organize bots and indicators in folders and subfolders, like in Metatrader 4.
-- Even better than folders, the possibility to assign labels and sublabels to bots and indicators (0, 1 or more labels for every bot or indicator), and then filter by label, like the messages in Gmail.  Also, it would be nice to have some sort of archival feature or label, where I can send the bots that I don't want to see again (for example, ideas that didn't work) but that I don't want to delete for good.  There should be a feature to manage labels (create, delete, etc), like in Gmail.

Hi, 

this is the way I do it. I do not know if there is a better way, but this works for me.

This is the workaround I am using until they fix this bug:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.WEuropeStandardTime, AccessRights = AccessRights.None)]
    public class xxx : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        private DateTime lastOpenTime;
        protected override void OnStart()
        {
            this.lastOpenTime = MarketSeries.OpenTime.LastValue;
            Print("start " + MarketSeries.OpenTime.LastValue.ToShortTimeString());
        }
        
        protected override void OnTick()
        {
            if (!MarketSeries.OpenTime.LastValue.Equals(this.lastOpenTime))
            {
                myOnBar();
                this.lastOpenTime = MarketSeries.OpenTime.LastValue;
            }
        }
        
        private void myOnBar()
        //protected override void OnBar()
        {
            Print("onbar " + MarketSeries.OpenTime.LastValue.ToShortTimeString());
        }
    }
}

This issue occurs when I run the robots on a demo account. On a live account it works fine.

In my previous post I forgot to mention that I am using the broker IC Markets.

I left the program running overnight, and this is the printout that I get for M5. Very weird.

Hello,
I am having the same problem as described above.

Today I noticed that my robots did not work properly.
The OnBar event waS not triggered on each and every bar.

I have prepared a little test program as follows:

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.WEuropeStandardTime, AccessRights = AccessRights.None)]
    public class xxx : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            Print("start " + MarketSeries.OpenTime.LastValue.ToShortTimeString());
        }
        protected override void OnBar()
        {
            Print("onbar " + MarketSeries.OpenTime.LastValue.ToShortTimeString());
        }
    }
}

The output of this program in EURUSD M2 is as follows:

19/08/2019 18:16:17.944 | cBot "xxx" was started successfully for EURUSD, m2.

As you can see many bars are missing.
The same problem happens in M1, M5 and M15. I did not try other timeframes.

Running several instances of the robot in different timeframes, 
it seems that when a candle is missing, it is missing in all 
timeframes that apply; and when a candle is not missing, it is
not missing in all timeframes that apply.

I have run the program on two different instances of ctrader,
on different computers on different locations. The issue is 
present in both instances of ctrader, and it seems that 
on both computers the printout is missing the same candles.

I have restarted the ctrader platform and the computer, but the problem is still there.

I have never noticed this issue before today.

Any help would be very much appreciated.

Regards

To illustrate further this issue, in the image bellow I have loaded the indicator in four H4 charts 
of EURUSD, USDCAD, XAUUSD and AUDJPY. The line is different in all four charts, and only the one of XAUUSD is correct.

Please let us know if we are doing anything wrong in the use of MarketData.GetSeries or instead this is a bug that can be fixed in due course.

Thanks a lot,

Guillermo
