RE: Backtesting Options with custom timeframes

eivaremir said:

I've just written a bot which reads renko graphics, and I want to backtest it but this function isn't available, do you have plans to incorporate it in the future?

Hi eivaremir,

Yes this is in our plans. It will be added in one of the upcoming updates.

Hi erikvb,

There are several issues with your cBot. I made some changes so that you can build it but you need to check if this is what you want. See the code below

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.UTC, AccessRights = AccessRights.None)]
    public class HMABOT : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

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

        [Parameter("Volume", DefaultValue = 1000)]
        public int Volume { get; set; }

        [Parameter("Source")]
        public DataSeries Source { get; set; }

        [Parameter("Periods", DefaultValue = 14)]
        public int Periods { get; set; }

        internal HMASignals HmaSignals { get; set; }

        public bool IsBullish = false;
        public bool IsBearish = false;


        private MarketSeries HmaDaySeries;
        private HMASignals _hmaSignal;

        protected override void OnStart()
        {
            // Put your initialization logic here
            HmaDaySeries = MarketData.GetSeries(TimeFrame.Daily);
            _hmaSignal = Indicators.GetIndicator<HMASignals>(Periods,Source,false,false,1,false,1);
        }

        protected override void OnTick()
        {
            // Put your core logic here
            // BEARISH
            if (_hmaSignal.IsBearish && Positions.FindAll(Label, Symbol, TradeType.Buy).Length == 0)
            {
                IsBearish = true;
                IsBullish = false;
                close(TradeType.Sell);
                trade(TradeType.Buy);

            }

            // BULLISH
            if (_hmaSignal.IsBullish && Positions.FindAll(Label, Symbol, TradeType.Buy).Length == 0)
            {
                IsBearish = false;
                IsBullish = true;
                close(TradeType.Buy);
                trade(TradeType.Sell);
            }
        }

        private void close(TradeType tradeType)
        {
            foreach (var position in Positions.FindAll(Label, Symbol, tradeType))
                ClosePosition(position);
        }

        private void trade(TradeType tradetype)
        {
            ExecuteMarketOrder(tradetype, Symbol, Volume, Label);
        }
        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Hi James,

As the message clearly states, you need to end your region somewhere. You start your region here

        #region Indicator declarations
        private DSSBressert _DSS { get; set; }

Dear amsman,

There is no such thing as a single “root” memory issue with cTrader that needs to be addressed. First of all, most of the memory issues are caused by poorly programmed custom cBots and indicators.No matter how efficiently we program cTrader, if the custom cBot/Indicator uses a lof of memory, there is nothing we can do about it. This is why we always ask if a trader is running a custom cBot/Indicator and if yes, we ask for the code to investigate further.

In the rare cases a memory issue is caused by cTrader itself, we ask for the cooperation of traders to address it. I completely disagree with your statement “There is no support offered in these forums to eleviate the problem.... Other than post me you code and we'll have a look...”. We always ask for detailed troubleshooting information to reproduce the problem and we even proceed with TeamViewer sessions to investigate issues on trader machines. As soon as we identify the cause of each issue, we aim to resolve it with the next update. Many members of the community can confirm that they have received such treatment and that their issues have been handled and resolved in a reasonable time.

Also please note that cTrader is an evolving platform that constantly changes as new features and functionalities are introduced.Therefore there is no once and for all solution for everything unless we stop developing the platform. Issues will appear and will be resolved constantly as we release new versions of the platform. This is one of the main reasons we are releasing beta versions before releasing  to brokers. So that you can test it and report to us any issues you might have. Therefore if you still face memory issues with cTrader, let us know how to reproduce and we will be happy to have a look.

Best Regards,

Panagiotis

Hi lec0456,

ObjectHoverChanged works for non interactive objects as well. See below how to get the index of the hovered line

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.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        protected override void OnStart()
        {
            Chart.ObjectHoverChanged += OnChartObjectHoverChanged;
            var divLine = Chart.DrawVerticalLine("Dayend", Server.Time, Color.Orange, 1, LineStyle.DotsRare);
        }

        void OnChartObjectHoverChanged(ChartObjectHoverChangedEventArgs obj)
        {
            if (obj.IsObjectHovered)
            {
                if (Chart != null)
                    Chart.DrawStaticText("hoverText", obj.ChartObject.Name, VerticalAlignment.Top, HorizontalAlignment.Left, Chart.ColorSettings.ForegroundColor);
                if (obj.ChartObject is ChartVerticalLine)
                    Print("Index " + (obj.ChartObject as ChartVerticalLine).Time);
            }
            else
                Chart.RemoveObject("hoverText");
        }

        protected override void OnTick()
        {
            // Put your core logic here
        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Hi dmn,

We have investigated this issue and it seems you are using a custom indicator (I-Sessions) which causes the memory issue. Can you try removing the indicator and letting us know if it resolves the issue?

Thanks for posting in our forum. I downloaded the cBot but there is no source code. Can you please send it with source code? Also you can just post the code here, no need to send files.

Hi Sasha,

Yes it is a bug and we are aware about it. I just wanted to make sure it is the one we know. It happens on optimization when cBots get data form other timeframes than the one they execute on.

Best Regards,

Hi Sasha,

I have checked your cBot and you are using data from another timeframe

       [Parameter("S & R TimeFrame", DefaultValue = "Daily")]
        public TimeFrame SRTimframe { get; set; }
.
.
.

     seriesSR = MarketData.GetSeries(SRTimframe);
.

RE: IsOverlay not work as previous version did.

uvwxyz said:

Hi,

Previously one could use in the Indicators opened chart's tool : f / Custom and overlay a custom indicator B ( built with declaration: "IsOverlay = true;) over another custom indicator A (which is already displayed in a panel), by selecting (in the  f / Custom dialouge box)  B as the 'Indicator' and selecting an output series of indicator A as the input series (source) for indicator B.

Now doing so draws the Indicator B on the main chart which is useless, and also takes away a lot of power of cTrader custom indicators. Previously it drew on the panel of Indicator A.

Can you please, make this previously available funtionality available again.

Cheers.

Hi abs,

This is a bug and we will fix it.

Hi Ben,

There is no other feature at the moment.You can try double clicking on the Trend Line and choose Show Angle. This feature will help you drawing a straight line.
