Thanks @PanagiotisCharalampous. Is there a temporary solution/hack I could use locally while you're guys finishish a proper fix? It's just a showstopper that stops the whole work I'm doing. 

Unfortunately there isn't. It seems that some data of the specific broker is corrupted and needs to be fixed

Ok, clear. How long do you think it will take to fix the data? Are we talking more days or weeks?

Yes and we are working on a solution.

RE: Sometimes MarketData.GetBars hangs forever

PanagiotisCharalampous said: 

Hi there,

Can you share the complete cBot code as well as the broker, so that we can reproduce and investigate?

Best regards,

Panagiotis

cTrader restart fixed the issue. Are there cTrader internal logs that I could share with you when it happens in the future?

RE: % Commission

PanagiotisCharalampous said: 

Hi there,

There is no such option at the moment.

Best regards,

Thank Panagiotis,

But that makes cTrading backtesting completely useless for anything except FX. Nobody trades stocks in millions with the same fee for different stocks. Here is a typical fee structure for CFD/stocks:

Are you guys planning to implement it in the near future?

RE: MarketHours TimeTillClose Backtesting Bug

Hi there,

Please send us the complete cBot code and your broker so that we can reproduce this issue on backtesting.

Best regards,

Somehow I can't reproduce it anymore. Really weird. I'll keep an eye on it.

Hm, actually

Action<Bars> callback = o =>{        Bars result = o;    Print("Market Bars found");};
MarketData.GetBarsAsync(TimeFrame.Daily, "American_Express_(AXP.N)", callback);

also hangs forever and never moves past the GetBarsAsync line.

Any suggestions how to avoid it?

Ok, found GetBarsAsync. Just wondering why did you guys decide to implement it with callbacks rather than proper Task Async methods?

RE: cTrader doesn't set SL bug

PanagiotisCharalampous said: 

Hi there,

This is not a bug, it's by design. You should check for these cases in your code and act accordingly.

Best regards,

Panagiotis

Hi Panagiotis,

How come not setting a stop loss can be by design? Shouldn't the ExecuteMarketOrder return IsSuccessful = false if the code can't place the trade I want?

Hi again,

Thank you. We managed to reproduce the problem and we will fix it in an upcoming release.

Thanks @PanagiotisCharalampous . Does cTrader autoupdate on a new version? I can't seem to find this option in the settings.

Hi PanagiotisCharalampous ,

Is this information available on the UI?

No it is not

Thanks. Are there plans to add this information at least to the UI? Because I can see this info for my Optimisation runs, but for whatever reasons it's not available for backtesting…

RE: CFD Backtesting Margin Calculations Bug

PanagiotisCharalampous said: 

Hi there,

Can you please share the complete cBot code and your broker so that we can reproduce this behavior?

Best regards,

Panagiotis

Hi, 

sure, that's the whole code:

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.EasternStandardTime, AccessRights = AccessRights.FullAccess)]
    public class FreeMarginBug : Robot
    {
        [Parameter(DefaultValue = "Hello world!")]
        public string Message { get; set; }

        protected override void OnStart()
        {
            Print(Message);
        }

        protected override void OnBar()
        {
            if (Time == new DateTime(2023, 03, 20, 12, 0, 0))
            {
                double qty = 109;
                Print($"Account Balance: {Account.Balance}");
                Print($"Margin Before: {Account.Margin}");
                Print($"Free Margin Before: {Account.FreeMargin}");
                Print($"Price: {Symbol.Ask}");
                ExecuteMarketOrder(TradeType.Buy, SymbolName, qty, "MyBot", 40, 20, "Test", false);
                Print($"Expected Margin: {qty * Symbol.Ask / Symbol.DynamicLeverage.First().Leverage}");
                Print($"Actual Margin: {Account.Margin}");
                Print($"Free Margin After: {Account.FreeMargin}");
            }
        }
    }
}

Steps to reproduce:

1. Create a new bot “FreeMarginBug”
2. Select Apple as a financial instrument
3. Set the first date of the backtesting to 19/03/2023
4. Run the backtesting and check the log window 

Additional data:

• Broker: PepperStone
• Account Type: Test
• Account Balance: 10,000

The same happens with any stock CFD on any date and any quantity. Specific stock and date was choosen just to simplify the debugging process.
