Hi JerryTrader,

The indicator should print the messages if you are in the cTrader Automate section. If not, please share the source code to check. Alternatively, you can export your messages in a csv file.

I can't get the indicator logs displayed anywhere else than the Indicator instance itself.

If not, please share the source code to check.

using System;
using cAlgo.API;
using cAlgo.API.Internals;
using cAlgo.API.Indicators;
using cAlgo.Indicators;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TestPrintMessages : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }
        
        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        [Output("Moving Average")]
        public IndicatorDataSeries ResultMtfMa { get; set; }

        private Bars _mtfBars;
        private MovingAverage _mtfMa;
        
        protected override void Initialize()
        {
            _mtfBars = MarketData.GetBars(TimeFrame.Daily);
            _mtfMa = Indicators.MovingAverage(_mtfBars.ClosePrices, 100, MovingAverageType.Exponential);
        }

        public override void Calculate(int index)
        {
            var mtfMaIndex = _mtfBars.OpenTimes.GetIndexByTime(Bars.OpenTimes[index]);
            if (mtfMaIndex != -1)
            {
                Print(string.Format("Index is {0}. Mtf Index is {1}", index, mtfMaIndex)); 
                ResultMtfMa[index] = _mtfMa.Result[mtfMaIndex];
            }
        }
    }
}

Given the code above :

OK : cTrader Automate section -> Indicators -> Test Print Messages instance

NOK : cTrader Automate section -> cBot -> Basic cBot that does nothing else than printing a message on start

NOK : cTrader Automate section -> cBot -> Backtesting the basic cBot that does nothing else than printing a message on start

Hi JerryTrader,

You haven't shared your cBot code.

Hi JerryTrader,

Your cBot does not use the indicator in any way. Why do you expect to see any messages?

RE:

Hi PanagiotisCharalampous,

As I said, my chart does, not my cBot.

JerryTrader said:

For some unknown reason, it doesn't display the same way when I add it to a chart of a cBot backtest, so I would like to see the logs of my indicator to understand why some Outputs are not displayed on the chart.

I have a complex indicator that works fine in the Indicators tab, the cBot live instance and in cTrader Trade, but when I add it to a chart of a cBot backtest, it doesn't behave the same way.
I have no idea why an indicator would be displayed differently when used with the same settings, so I want to debug this by writing some messages and see what's going on.

Hence my question:

Is there a way to display logs (or get a file somewhere) of an indicator when it is instanciated elsewhere than the Indicator tab?

Hi JerryTrader,

Indicators added to the backtesting chart cannot use the backtesting log to print messages. Maybe try calling the indicator from a cBot. In this case, you should be able to see the messages.

Hmmm ok. 
I will try that. I can also log indicator messages to a file so that I don't have to create a cBot just to get logs from an indicator.

As long as I have workarounds, I'm fine ;)
But I think it could be handy to add a feature to let the user choose the log sources in the Log tab.

While you're there (sorry, this is off-topic but I can't find any answer...):
For 2-3 weeks now, I don't receive any notifications about the topics I am subscribed to. For example, if I don't visit/refresh this page, I'm not able to see if you answered to it.
I checked my settings and everything seems fine to me. I posted a message in the cTrader Web section, and I reported an issue through Pepperstone cTrader. I really have no idea where to report this so it can be fixed...

Can you please redirect me to the right place, or report this to the right team ?
