Hi,

Can you send us the troubleshoot report by adding this forum thread URL to your reference description?

You can explain what actions you did that caused cTrader to become unresponsive?

If possible can you send us the code of cBots you used before cTrader became unresponsive?

 

Done.

I can cause even the new version 4.1 to become unresponsive when I switch views from Trade to cBot instance view. In v4.0 cTrader would go unresponsive when I try to scroll through the cBot list on the left of the window. It appears that every time cTrader went unresponsive I was trying to interact with its display, clicking, dragging, selecting, etc.

Hi,

Our team checked your troubleshoot report and they found that the issue is your cBots, in order to reproduce the issue we need your cBot code and a video that shows how to reproduce the issue.

RE:

amusleh said:

Hi,

Which broker cTrader you are using and which version?

Did you submit the troubleshoot report?

cTrader is not single-threaded, and it uses multiple threads when it needs.

1. IC Markets.

2. Yes.

3. Ok, it seems to hammer just one thread out of 6 or 24 available, so a process of some sort is holding up the rest.

RE:

I have the same problem. I submitted the issue using the cTrader reporting tool. The only way that I can run cTrader is if I allocate at least 8Gb to the virtual machine and that is fantastically excessive. I used to be able to run it well on a 2Gb VPS.

It has always been slow and I  feel it is not really improving in that matter for instance it takes a few minutes to start my profile  sadly because quickly operating is critical. . Perhaps upgrading to .latest version of Dot Net Framework from 7 years old 4.0 will do, thouight.

RE:

This looks great! Thank you.

One question, why are we declaring the following as a user variable? Is there any benefit to making the timer not refresh every second for example?

[Parameter("Timer Interval (Seconds)", DefaultValue = 1, MinValue = 1)]
        public int TimerIntervalInSeconds { get; set; }

V.

amusleh said:

Hi,

There are several issues with your code, first you should not put any time based logic inside OnBar method, instead you should use the OnTimer method and start timer on an interval that suits your specific needs.

You should not use TimeInUtc, the position EntryTime is set based on your robot time zone attribute, and you should use Server.Time not Server.TimeInUtc, it only works if your robot time zone is UTC.

Here is an example cBot:

using cAlgo.API;
using System;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class ClosePositionOnTime : Robot
    {
        [Parameter("Timer Interval (Seconds)", DefaultValue = 1, MinValue = 1)]
        public int TimerIntervalInSeconds { get; set; }

        [Parameter("Trade Type", DefaultValue = TradeType.Buy)]
        public TradeType TradeType { get; set; }

        [Parameter("Profit", DefaultValue = 100)]
        public double Profit { get; set; }

        [Parameter("Close Time (Minutes)", DefaultValue = 60)]
        public double CloseTimeInMinutes { get; set; }

        [Parameter("Label", DefaultValue = "My_cBot")]
        public string Label { get; set; }

        protected override void OnStart()
        {
            Timer.Start(TimerIntervalInSeconds);
        }

        protected override void OnTimer()
        {
            var currentTime = Server.Time;

            foreach (var position in Positions)
            {
                // Filter positions
                if (!string.Equals(position.Label, Label, StringComparison.OrdinalIgnoreCase) || !position.SymbolName.Equals(SymbolName, StringComparison.OrdinalIgnoreCase) || position.TradeType != TradeType)
                {
                    continue;
                }

                // Close if position meet the condition
                if (position.EntryTime.AddMinutes(CloseTimeInMinutes) >= currentTime && position.NetProfit >= Profit)
                {
                    ClosePosition(position);
                }
            }
        }
    }
}

RE:

Thank you Panagiotis.

Sorry for the clearly basic following question, but I learn by doing...

How do I change 

(TimeFrame.Hour).ClosePrices

Into an expression that allows me to declare a user selectable  time frame and source from the cBot settings for example these:

[Parameter("Timeframe", Group = "RSI", DefaultValue = "Minute10")]
        public TimeFrame RSITimeFrame { get; set; }

[Parameter("Source", Group = "RSI")]
        public DataSeries Source { get; set; }

Thanks,

Victor

Hi Victor,

Here is an example

 var rsi = Indicators.RelativeStrengthIndex(MarketData.GetBars(TimeFrame.Hour).ClosePrices, 14);

PanagiotisCharalampous said:

Hi victor.major,

This will be fixed in v3.8. The beta will be released soon. The problem is that when you assign the values to backtesting Close values are set as Source instead of Open. Please try changing the source manually to Open and let me know if this resolves the problem.

Ok that is great. I look forward to v3.8. The same problem occurs with tick data and not just with the example cBot, but also with the closed source ones.

Hi Panagiotis,

when do you anticipate this update to come? I am still unable to obtain sane optimization/backtesting results. The latest optimization attempt gives me a USD 3.5k profit in a given period, while the exactly the same, identical settings (both using tick data) in backtesting results in a USD 5k loss. This is not really useful.

RE:

Thank you for replying Panatiotis,

this happens with at least one closed source cBot. Regarding an open source example, the "Sample Breakout cBot" exhibits this behaviour. 

Steps to reproduce are as above:

1. Optimise

2. Apply

3. Get a vastly different result compared to the optismisation run whose settings were applied.

trander002 said:

we need this

Spotware made a decision to develop cTrader on c#, a proprietary MIcrosoft language and they take extensive use of .net libraries which are again proprietary to the Windows platform. Spotware would need to basically start again to make a cross platform version, which is actually what they should do. The sooner they start the sooner that 10 man years project time will start counting down.

RE: RE: Saving optimisation results

phill.beaney said:

I don't understand why more people aren't requesting this, unless there is a way to save the data from a temp file that everyone except me is ware of.

Any Ideas welcome.

I really like this to be implemented in order to do proper research, currently backtests and optimizations cannot be shared or exported, the only option is to do screenshots, which is awful.

Seconded and thirded +1... I now see that I was not mistaken and that there is in fact no way to export/save/restore optimisation data. I find this so unusual that I am still not convinced that I am not missing something. I am not aware of any other modeling or simulation software that does not save the simulation results, ie. I am not comparing cTrader to MetaTrader. There is a basic expectation that if you spend one day on generating simulation results that you will be able to work with them after the fact, or that they will be saved somewhere in case there is a software problem or a crash - which is what happened to me just then.

RE:

Something I forgot to mention is that you can export the history of backtesting and optimization results, if you right click inside the History tab and select "Export to Excel". I hope this helps!

Has saving optimisation results been addressed? I am using cTrader 3.7. It crashed before I could look at the optimisation results. Upon restart all the results were gone and I do not see any trace of any activity in History or Journal and I see no obvious way to access the optimisation results.

Please let me know that you are in fact saving them to a file somewhere and let me know where that file is.

RE: RE: RE: RE:

Nevertheless the bug has been replicated by the cBot developer and I was informed that the error is with the cTrader. When will you be releasing an update? I am keen to resume my optimisations.

PanagiotisCharalampous said:

victor.major said:

1. Optimization may have indeed finished. The parameters are different across different runs, however I have no way of seeing which parameters are optimal as all the results are zeroed.

2. When I press "play" the optimizer quickly goes through the sequence of run numbers and stops at 574 and shows the screen above.

3. cBot runs well and two optimisations completed successfuly on 3.6

4. I restarted cTrader, once automatically during update, once manually. I also removed the cBot instance and assigned it again. No change.

5. cBot is closed source.

My guess is that this is some kind of cache issue. Can I manually scrub the optimizer cache and start again?
