Hi there,

It's better to ask your broker why this happened.

Best regards,

Hi there,

We have received the exception and the issue will be solved in an upcoming release.

Regarding the SL issue, we would need the cBot code and backtesting parameters in order to reproduce this and explain what happens.

Best regards,

Panagiotis

Hi Panagiotis,

Here is the test code that produce the SL issue, I'm using Nikkei225, Hm1 for testing

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using cAlgo.API;
using cAlgo.API.Collections;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

namespace cAlgo.Robots
{
    [Robot(AccessRights = AccessRights.FullAccess, TimeZone = TimeZones.EasternStandardTime)]
    public class Test2 : Robot
    {        
        [Parameter(DefaultValue = 10, MinValue = 0, MaxValue = 500, Step = 10)]
        public int lossCut { get; set; }
        
        [Parameter(DefaultValue = 10, MinValue = 0, MaxValue = 500, Step = 10)]
        public int takeProfit { get; set; }
        
        double volume = 0.0;
        
        protected override void OnStart()
        {
            // To learn more about cTrader Automate visit our Help Center:
            // https://help.ctrader.com/ctrader-automate
        }

        protected override void OnBarClosed()
        {
            volume = 10;
            
            var last_buy_position = Positions.Where(x => x.Label == "Test" && x.SymbolName == Symbol.Name && x.TradeType == TradeType.Buy).OrderByDescending(x => x.EntryTime).FirstOrDefault();
            
            // Handle price updates here
            if(MarketData.GetBars(TimeFrame, "US500").ClosePrices.Last(0) > MarketData.GetBars(TimeFrame, "US500").OpenPrices.Last(0))
               if (last_buy_position == null || Symbol.Ask < last_buy_position.EntryPrice - 100 * Symbol.TickSize)
                   ExecuteMarketOrder(TradeType.Buy, Symbol.Name, volume, "Test", lossCut, takeProfit, (Server.Time - Bars.Last(0).OpenTime).Milliseconds.ToString());            
        }
        protected override void OnTick() {
            foreach(var position in Positions.FindAll("Test", Symbol.Name))
                if(position.StopLoss == null)
                    ModifyPositionAsync(position, Symbol.Ask - 20 * Symbol.PipSize, position.TakeProfit);
                
        }

        protected override void OnStop()
        {
            // Handle cBot stop here
        }
    }
}

Can you also tell me the broker? This usually happens when your SL falls within the symbol's spread. Please check if this is the case

Hi there,

Why don't you use backtesting to test your cBots?

Best regards,

Panagiotis

I've been looking for the optimization / backtesting section for my cBot. Since the update, I haven't been able to locate it. I'm using Desktop version 5.0.25

How do I do that? When my backtest finishes, I am unable to change the timeframe on the backtest tab, the options are greyed out. Changing the timeframe under the Algo left panel does not update the backtest window timeframe either.

 

Hi there,

It looks like a bug. You should be able to change it from the instance.

Best regards,

Panagiotis

Hi Panagiotis,

I can indeed change the timeframe from the instance as per you screenshot, but the problem is when you change it there the chart on the finished backtesting tab is not changed, it stays on the timeframe of when you ran the backtest.

Kind regards

Beyers

Hi Beyers,

The timeframe will change as soon as you start backtesting again.

Best regards,

I have just tried this option and works fine. Can you provide more information e.g. record a video demonstrating this happening?

Hi Tarek,

One of the changes in cTrader 5.0 is that the data for all passes is kept. So if your cBot is printing too much information in the log, this could eventually hinder the performance of optimization

Hi there,

No it does not include swaps and commissions. If you need them, you would need to develop your own methods.

Hi there,

This is by design. If the price jumps more that one bar, then the method is only executed once for the last bar.

Hi there,

There is nothing cTrader specific here. Pip size is determined by the broker and the platform behaves accordingly.

Hi Cnicholasdownie,

No this is not possible and we do not have plans to add such an option. You cannot change the chart timeframe while the cBot is running.

Panagiotis, what about after the visual backtest has finished? Technically the bot is not running anymore, so why are we not able to change the timeframe then, but keep the backtest trade history?

After the backtest finishes it is possible to change the timeframe

Hi

How to get the troubleshooting?

Check the link in my first reply

Hi

OK.

But, I mean that how to look the “error log of cTrader”, to find the reason for frequent disconnections.

Thanks

There is no such log available to you

Hi there,

See the correct formula below

        private double CalculateSwap(double swap, double volume)
        { 
            return AssetConverter.Convert(Symbol.SwapLong * Symbol.PipSize * volume, Symbol.QuoteAsset, Account.Asset ); 
        }

Best regards,
