Hi there,

Better share a complete cBot code so that we can try to reproduce.

Thank you for your reply.

Here is some example code -

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.None)]
    public class sdfdsfdsf : Robot
    {
        protected override void OnStart()
        {
            System.Diagnostics.Debugger.Launch();

            string[] xSymbolsA;
            cAlgo.API.Internals.Symbol[] xSymbolsX;

            xSymbolsA = (this.Symbols.ToArray());
            xSymbolsX = (this.Symbols.GetSymbols(xSymbolsA));

            xSymbolsX = (xSymbolsX);

            this.Stop();
        }

        protected override void OnTick()
        {
            // Handle price updates here
        }

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

The code either times out, or produces a bunch of 'Log' 'Error' messages similar to -

"10/02/2023 11:40:37.568 | Failed to get symbol 'USDCHF': Symbol not found or has no quotes."

This happens for pretty much all symbols.

Thank you for your time,

An update -

I installed the latest 'cTrader' 'Desktop' (4.6.3.13401), direct from the ctrader.com website.

I previously was using my broker 'cTrader' download (4.5.9).  I didn't realize that I could use the 'non broker' 'cTrader'.

Anyway, I now get an 'error' 'pop up' window, as follows -

#Exception #6E789BB3 in cTrader 4.6.3.13401

An error has occurred.  The problem has been submitted to the cTrader team.  We apologize for the inconvenience.  Please restart cTrader.

If run through 'debugger' in 'VS2022', I get an 'Exception User-Unhandled' error, with the details -

I don't know if that helps with understanding the situation.

Thank you for your time,

RE:

Hi there,

I'm having similar problems with the MarketData.GetBars() Method. Currently running Version 4.6.7., where I get an Error

Failed to get symbol 'CADCHF': Symbol not found or has no quotes

for all symbols (CADCHF was just an example), except the symbol that is set in the bot options. I don't know exactly since when it doesn't work anymore, but a few weeks ago I had no such problem and everything worked well.

My broker is FxPro.

Best,
